In December 2022, the first HIP batch on Latin American soil was performed. The journey to success in HIP, as any HIP user will agree, is a bumpy road. What are the challenges that aerospace manufacturers with in house heat treating should be aware of when considering HIP processing? Learn how HT-MX Heat Treat & HIPing — the heat treater who ran the first HIP batch in Latin American history — navigated the transition from small tooling jobs to HIP processing for aerospace parts.

Writing this story as the first Latin American company to offer Nadcap accredited hot isostatic pressing brings a flood of memories and images to mind. HT-MX’s beginnings were simple, but also filled with challenges, failures, and lessons. When the company began, we were certain that, though small, we were still a “heat treat plant” and not just a shop.

Being located in Mexico means that there were large companies with headquarters located far away — potential customers — that would be deciding on their heat treat supplier close to their location. We worked hard to be and to present ourselves as being very professional. But a lesson soon learned was that achieving trust with partners takes a lot more than a good speech and a clean plant.
Unsurprisingly, the first jobs were simple tooling work, like quench and tempering tooling and carburizing gears. A junior engineer and I would drive around in my old hatch-back to local machine shops and pick up a small shaft or gear and bring it back to the plant. We would get so excited when we got the case depth right.
With minimal resources, we decided to complete quality control ourselves. We became friends with a quality manager from a local company, and he came over to help on weekends and after 6:00pm until the audit date came. His knowledge is still in use at HT-MX to this day. I remember celebrating with a “Carne Asada” (a Mexican style barbecue) when we finished that first audit, thinking we had just made a huge step forward, not realizing how far away we still were from our vision.

But as time passed, we turned our attention to the aerospace industry in Chihuahua, a city with four OEMs. We received the AS9100 certification and started working on Nadcap accreditation. This required time, but by then, a pretty strong engineering team was in action, and successfully obtained Nadcap accreditation in late 2019. Again, we celebrated with a Carne Asada, this time, with a better understanding on where we were and what future challenges we needed to face.
Taking On Hot Isostatic Pressing

The pandemic hit. Boeing’s 737 Max crisis continued to impact the industry. Moving into aerospace was slow with limited volume, especially compared to what we had seen in the automotive and oil and gas industry. But by now, international companies were more willing to transfer heat treat operations to Mexican suppliers, and we were ready, beginning with running aluminum batches, precipitation hardening, annealing, and other standard processes. It was during this early start to serve the aerospace industry that we heard about hot isostatic pressing (HIP).
Around 2019 during an aerospace cluster event, an OEM with a local presence approached us with their HIP requirements. I had only heard of HIP, but I was immediately interested — until I found out how much one of those machines cost!
But good financing through government programs helped make this HIP project a reality. Timing was not the best, as the federal election in Mexico caused a temporary Mexican currency depreciation, handicapping the project at its beginning.
Getting the proper certifications and validations proved to be a long and complex process, too. Theoretically, we knew what to expect, in terms of getting the Nadcap checklist approved, but the reality was a little different. Gaining Nadcap certification slowly builds a certain culture into any company in its day-to-day activities. Translating that culture into a completely different business unit, new crew, and new process proved to bring its own challenges.
HIP Challenges: Pressure, Temperature, Thermocouples, and Argon Supply
Heat treating usually handles temperature, atmosphere control (or lack of), and regular traceability requirements. HIP, however, adds a few new dimensions to what we usually see: internal pressure, very high temperatures — up to 3632°F (2000°C) — and argon supply. It was the first time HT-MX dealt with a process that incorporated up to 30,000 psi and also used a lot of high purity argon.
Pressure has its own challenges, though the HIP press takes care of those challenges. Still, the internal workings on these kinds of presses are fundamentally different than that of a regular heat treat furnace. Yes, you need to heat it up, but apart from that, it’s not even a furnace but a press. Understanding how the machine works, what happens inside with all that pressure, how it affects the components undergoing hot isostatic pressing, and how it affects the baskets you’re using is a critical learning curve.
High temperatures change everything about running these types of cycles. We work with metals, which means temperatures range between 1832°F and 2372°F (1000°C and 1300°C). This has an impact on thermocouple selection, calibration, and more; with the company’s thermocouple product suppliers based in the U.S., this entails more challenges and extra costs. I have lost count on those urgent same-day trips to the border to retrieve critical spares in time. It’s an 800-km/498-mi roundtrip! We have fortunately found a great supplier that has offered the technical feedback we needed, and we have started to finally understand and control our thermocouple consumption. Although, I must be honest here, we still have a lot to learn in this aspect.
Then, there’s the argon supply. HT-MX never expected it to be a challenge, but it turns out getting the proper supplier — one that understands the requirements and is willing to work with you from validation to production — is key. You might be able to start your validation process using argon transported in gas containers but eventually you will need to switch to liquid argon. That proved to be more difficult than expected. There are not many projects requiring these kind of alliances locally. Getting the right supplier was key and more of a challenge than expected. And then came the lessons on efficiently using the liquid argon, avoiding excessive venting of the tank, and being all around smart with the HIP schedule. This has been a constant learning process, one that has high costs.
Final Hurdles: Certifications, Current Events, and Energy Costs
Once our company had the Nadcap certification, we still needed to get the OEM’s approval for the HIP process, then the approval for the specific version of the HIP process, and then the actual approval for the part numbers.
These approvals were handled by the headquarters’ engineering department and not locally. It was a time-consuming process, with several test runs, lab testing, multiple audits, visits, and more testing, etc. And while all of this was happening, we still had to design the operation, locate critical suppliers not available in Mexico, create alliances with suppliers, etc. Writing this down in a few lines makes it seem simpler and quicker than it really was.
Additionally, in instances like this, Mexican companies, especially small ones, face much more scrutiny than U.S. or European-based companies, and must prove themselves in every single step. It makes sense, even if it feels a little unfair, as HT-MX had no proven track record of high tech processes such as HIP. It does cost extra time, extra care, and sometimes extra testing, but it is the reality we face and we must overcome the extra hurdles.
While navigating HIP approval, the pandemic hit. Months later, the war in Europe began with significant impacts on the cost of energy. Our main clients were high volume and low margin, and with energy prices rising, our competitiveness began to diminish. To adapt and evolve, we decided to add some smaller furnaces for smaller parts, invest in training and increased sales efforts, and focus on AMS/Nadcap-based customers, letting go of major clients. Slowly, things began to turn around.
The First Official HIP Batch in Latin America History
In December 2022, HT-MX ran the first official HIP batch in Latin American history. It was a long time coming. I always thought that running that first batch would feel like reaching the Everest summit. When the day came, it just felt like reaching Everest’s base camp. We still have a long way to go to be truly an established HIP supplier. Now, it’s back to climbing and shooting for that summit, that summit that will perpetually precede the next summit.
There are still several challenges: stabilizing new processes and improving established ones. But I am confident we will move forward in this new stage. And I am so looking forward to the next Carne Asada.

De herramientas simples al tratamiento térmico aeroespacial
Humberto Ramos Fernández Founder and CEO HT-MX
Escribir esta historia de como llegamos a ser la primera compañía latinoamericana en ofrecer prensado isostático en caliente acreditado por NADCAP trae a la mente una avalancha de recuerdos e imágenes. Los comienzos de HT-MX fueron simples, pero también llenos de desafíos, fracasos y lecciones. Cuando comenzamos la compañía, estábamos seguros de que, aunque éramos pequeños, éramos una “planta de tratamiento térmico” y no solo un taller.

Estando ubicados en México quiere decir que hay grandes plantas con corporativos lejos de aquis — clientes potenciales — que estarían decidiendo sobre su proveedor de tratamiento térmico lejos de nuestra ubicación. Trabajamos arduamente para ser y presentarnos como profesionales y confiables. Pero pronto aprendimos que lograr la confi anza con los clientes requiere mucho más que un buen discurso y una planta limpia.
Como era de esperar, los primeros trabajos fueron trabajos simples de herramentales, algunos templados y revenidos de herramentales y carburizado de engranes. Recuerdo como un ingeniero junior y yo dábamos la vuelta en mi viejo hatchback alrededor de talleres locales y recogíamos un pequeño eje o engranaje y lo llevábamos de regreso a la planta. Nos emocionábamos mucho cuando lográbamos la profundidad de capa correcta.

Con recursos mínimos, decidimos implementar el sistema de calidad nosotros mismos. Nos hicimos amigos de un gerente de calidad de una empresa local, venía a ayudarnos los fines de semana o después de las 6:00 p.m. hasta que llegó la fecha de la auditoría. Su enseñanzas aún se usan en HT-MX hasta el día de hoy. Recuerdo celebrar con una “Carne Asada” cuando terminamos esa primera auditoría, pensando que habíamos dado un gran paso adelante, sin darme cuenta de lo lejos que aún estábamos de nuestra visión.
Con el tiempo, dirigimos nuestra atención a la industria aeroespacial en Chihuahua, una ciudad con cuatro OEMs. Recibimos la certificación AS9100 y comenzamos a trabajar en la acreditación NADCAP. Esto requirió tiempo, pero para entonces contábamos con un equipo de Ingenieros bastante sólido y obtuvimos con éxito la acreditación de NADCAP a finales de 2019. Nuevamente, celebramos con una Carne Asada, esta vez con una mejor comprensión de dónde estábamos y qué futuros desafíos tendríamos que enfrentar.
Entrándole al Prensado Isostático en Caliente
La pandemia llegó. La crisis del 737 Max de Boeing continuó afectando a la industria. Empezar en sector aeroespacial fue lento y con un volumen limitado, especialmente en comparación con lo que habíamos visto en la industria automotriz y de oil&gas. Pero para entonces, las empresas internacionales estaban más dispuestas a trasladar las operaciones de tratamiento térmico a proveedores mexicanos, y estábamos listos, comenzando a procesar aluminio, endurecimiento por precipitación, recocido y otros procesos estándar. Fue durante estos inicios en la industria aeroespacial que escuchamos hablar del prensado isostático en caliente (HIP) por primera vez.
Alrededor de 2019, durante un evento del Cluster Aeroespacial de Chihuahua, un OEM con presencia local se acercó a nosotros con sus requerimientos de HIP. No conocíamos mucho de HIP, pero de inmediato me interesé . . . ¡hasta que descubrí cuánto cuesta una de esas máquinas!
Pero un buen financiamiento a través de programas gubernamentales ayudó a hacer realidad este proyecto de HIP. El momento no fue el mejor, ya que las elecciones federales en México causaron una depreciación temporal de la moneda mexicana, lo que obstaculizó el proyecto al principio.

Obtener las certificaciones y validaciones adecuadas resultó ser un proceso largo y complejo también. Teóricamente, sabíamos qué esperar en términos de obtener la aprobación para el checklist de NADCAP, pero la realidad fue un poco diferente. Obtener la certifi cación de NADCAP construye lentamente una determinada cultura en cualquier empresa en sus actividades diarias. Traducir esa cultura a una unidad de negocio completamente diferente, con un nuevo equipo y un nuevo proceso, demostró traer sus propios desafíos.
Retos en el HIP: presión, temperatura, termopares y argon
El tratamiento térmico generalmente trata de temperatura, control de la atmósfera (o la falta de ella) y los requisitos regulares de trazabilidad. HIP, sin embargo, agrega algunas dimensiones nuevas a lo que normalmente vemos: presión interna, temperaturas muy altas, de hasta 3632°F (2000°C) y suministro de argón. Fue la primera vez que HT-MX lidiaba con un proceso que incorporaba hasta 30,000 psi y también usaba mucho argón de alta pureza.
La presión tiene sus propios desafíos, aunque la prensa de HIP se encarga de ellos. Aún así, el funcionamiento interno en este tipo de prensas es fundamentalmente diferente al de un horno de tratamiento térmico regular. Sí, necesitas calentarlo, pero aparte de eso, no es ni siquiera un horno, sino una prensa. Comprender cómo funciona la máquina, qué sucede dentro con toda esa presión, cómo afecta a los componentes sometidos a prensado isostático en caliente y cómo afecta a las canastas y fi xtures que estás utilizando, es una curva de aprendizaje crítica.
Las altas temperaturas cambian todo sobre el funcionamiento de estos tipos de ciclos. Trabajamos con metales, lo que significa que las temperaturas oscilan entre 1832°F y 2372°F (1000°C y 1300°C). Esto tiene un impacto en la selección de termopares, calibración y más; con los proveedores de termopar basados en EUA, esto implica más desafíos y costos adicionales. He perdido la cuenta cuantos viajes urgentes de ida y vuelta por refacciones a la frontera he hecho. ¡Es un viaje redondo de 800 km! Afortunadamente, hemos encontrado un gran proveedor que nos ha ofrecido la retroalimentación técnica que necesitábamos, y finalmente hemos comenzado a comprender y controlar nuestro consumo de termopares. Aunque, debo ser honesto aquí, todavía tenemos mucho que aprender en este aspecto.
Luego está el suministro de argón. En HT-MX nunca esperamos que fuera un desafío, pero resulta que conseguir el proveedor adecuado, un que entienda los requisitos y esté dispuesto a trabajar contigo desde la validación hasta la producción, es clave. Es posible que puedas iniciar tu proceso de validación usando argón transportado en contenedores de gas, pero eventualmente necesitarás cambiar a argón líquido. Eso resultó ser más difícil de lo esperado. No hay muchos proyectos que requieran este tipo de alianzas a nivel local. Conseguir el proveedor adecuado fue clave y resultó ser un desafío mayor de lo esperado. Y luego vinieron las lecciones sobre cómo utilizar eficientemente el argón líquido, evitar el excesivo venteo del tanque y ser inteligente con el calendario de HIP en general. Esto ha sido un proceso de aprendizaje constante, uno que tiene altos costos.
Últimos obstáculos: certificaciones, eventos globales y costos energéticos
Una vez que nuestra empresa obtuvo la certificación NADCAP, todavía necesitábamos la aprobación de los OEM para el proceso HIP, luego la aprobación para la versión específica del proceso HIP y luego la aprobación real para los números de parte.
Estas aprobaciones fueron manejadas por el departamento de ingeniería del corporativo y no localmente. Fue un proceso que consumió mucho tiempo, con varias pruebas, pruebas de laboratorio, múltiples auditorías, visitas y más pruebas, etc. Y mientras todo esto sucedía, todavía teníamos que diseñar la operación, localizar proveedores críticos que no estaban disponibles en México, crear alianzas con proveedores, etc. Escribir esto en pocas líneas parece más simple y rápido de lo que realmente fue.
Además, en casos como este, las empresas mexicanas, especialmente las pequeñas, enfrentan mucho más escrutinio que las empresas estadounidenses o europeas, y deben probarse en cada paso. Tiene sentido, aunque se siente un poco injusto, ya que HT-MX no tenía un historial comprobado de procesos de alta tecnología como HIP. Cuesta tiempo extra, cuidado adicional y a veces pruebas adicionales, pero es la realidad que enfrentamos y debemos superar los obstáculos adicionales.
Mientras navegábamos en la aprobación de HIP, llegó la pandemia. Meses después, comenzó la guerra en Europa con impactos significativos en el costo de la energía. Nuestros principales clientes eran de alto volumen y bajo margen, y con el aumento de los precios de la energía, nuestra competitividad comenzó a disminuir. Para adaptarnos y evolucionar, decidimos agregar algunos hornos más pequeños para piezas más pequeñas, invertir en capacitación y aumentar los esfuerzos de ventas y enfocarnos en clientes basados en AMS / NADCAP, dejando ir a clientes principales. Poco a poco, las cosas comenzaron a mejorar.
La Primera Horneada Ofi cial de HIP en la Historia de Latinoamérica
En diciembre de 2022, HT-MX llevó a cabo la primera horneada oficial de HIP en la historia de Latinoamérica. Tomo bastante tiempo. Siempre pensé que hacer esa primera horneada se sentiría como llegar a la cima del Everest. Cuando llegó el día, solo se sintió como llegar al campamento base del Everest. Todavía nos queda mucho camino por recorrer para ser realmente un proveedor de HIP establecido. Ahora, volvemos a escalar y apuntamos a esa cima, esa cima que perpetuamente precederá a la próxima cima.
Todavía hay varios desafíos: estabilizar nuevos procesos y mejorar los establecidos. Pero estoy seguro de que avanzaremos en esta nueva etapa. Y estoy muy emocionado por la próxima Carne Asada.

Bodycote, a global thermal processing services provider, is expanding its hot isostatic pressing (HIP) capability in Greenville, SC in the U.S. The two vessels will be online by the end of 2022.
The new HIP capacity will focus on developments in additive manufacturing and advanced materials. This pairs well with the numerous vacuum furnaces and other capabilities at the facility that would support additive manufacturing clients. The Greenville site will serve the aerospace, defense, medical and general industrial customers in the Southeastern region.
"We are pleased to address our customer needs by bringing HIP services closer to their facilities," commented Stephen Harris, Chief Executive at Bodycote Group. "With the largest HIP operational capacity in the world, our continued investment demonstrates Bodycote’s commitment to align resources to serve our customers across North America."
Two atmosphere controlled retort box furnaces will be used for de-bindering ceramic matrix composite parts (CMC) as well as powder metals processing (PM) and hot isostatic pressing (HIP).
The main function of this L&L Special Furnace Co., Inc. furnace is to remove all organics and other materials used in the product prior to placing in a high fire vacuum chamber in a process called de-bindering: Parts are heated to 1220°F in a retort chamber that is pressurized with nitrogen. The by-products of the outgassing part are directed by pressure and flow out the rear of the furnace. The parts are then heated in a vacuum furnace to temperatures in excess of 2300°F. The result is a component that is stronger and lighter than titanium.
Aerospace and military have always been the key areas that CMC and additive technologies are applied. The CMC development is a key part of the subsonic ordnance project along with multitudes of other military applications. This technology allows for lighter and more durable aircraft, munitions, and body armor versus using some alloy and ceramic substitutes. Automotive has also always had a strong presence in the additive manufacturing industry as well.
It is new application areas were CMC technology is starting to shine. CMC technology is beginning to establish a presence in agricultural applications such as water desalinization, power and battery technology in providing lighter fuel cells. This technology will be applied to battery operated transportation vehicles, not only improving transportation capabilities but also lowering greenhouse emissions.
A hot isostatic press (HIP) was recently delivered to T.A.G. Medical Products Corporation Ltd. (TAGMPC), a manufacturer of medical and dental solutions that improve surgical procedures. The HIP will ensure the production of implants and surgical tools with the optimal material properties required by the exacting environments in which they are used.
Ran Weizman Executive Vice President T. A. G. Medical Products Corporation
"To increase production capacity, we invested in a new MIM (metal injection molding) production line," states Ran Weizman, Executive VP at TAGMPC. "The [Quintus Technologies] press will serve us for the implants and minimal cutting tools production, where high material uniformity and good mechanical properties are required."
Advanced proprietary features such as High Pressure Heat Treatment™ (HPHT™) and Uniform Rapid Quenching (URQ®) enable the Quintus press model QIH 15L to produce finished MIM parts with maximum theoretical density, ductility, and fatigue resistance. Incorporating heat treatment and cooling in a single process, HPHT combines stress-relief annealing, HIP, high-temperature solution-annealing (SA), high pressure gas quenching (HPGQ), and subsequent ageing or precipitation hardening (PH) in one integrated furnace cycle.
"All T.A.G. manufacturing processes, from A to Z, are done under one roof. Therefore, it is important for us to work with equipment that gives us this option,” Mr. Weizman comments.
With a new emphasis on disposable surgical instruments in the TAGMIM production chain, faster throughput and higher workpiece quality are also essential. The QIH 15L’s URQ capability achieves a cooling rate of >80K/s while minimizing thermal distortion and non-uniform grain growth. The press’s furnace chamber has a diameter of 6.69 inches (170 mm) and a height of 11.4 inches (290 mm) and operates at a maximum pressure of 207 MPa (30,000 psi) and a maximum temperature of 2,552°F (1,400°C).
The press was installed in the T.A.G. facility in May 2022.
