ALD Tratamientos Termicos

What ALD Tratamientos Termicos does

ALD Tratamientos Termicos S.A. de C.V. is a Mexican vacuum heat treatment contract manufacturer established in 2008 in Ramos Arizpe, Coahuila, as a wholly-owned subsidiary of ALD Vacuum Technologies GmbH (Germany), which itself sits inside publicly listed AMG Critical Materials N.V. (Amsterdam). The company operates as part of the ALD Heat Treatment Services (HTS) division alongside sister plants in Germany (VACUHEAT GmbH), the United States (ALD Thermal Treatment Inc., Michigan), and China (opened 2021), delivering standardized ModulTherm and VZKQ vacuum furnace capacity to customers who wish to outsource metallurgical processing rather than invest capital in their own equipment.

The Mexico facility runs three ModulTherm modular vacuum systems with 17 treatment chambers plus one VZKQ dual-chamber furnace and two nitriding furnaces, producing Low Pressure Carburizing (LPC) using Acetylene at 5-15 mbar, High Pressure Gas Quenching (HPGQ) at up to 20 bar Helium or Nitrogen, neutral hardening, vacuum annealing, cryogenic treatment at -80°C, nitriding, and high-temperature vacuum brazing. Quality is supported by in-house metallographic analysis, geometrical distortion inspection, and heat treatment consultancy services. Since start of production in 2008, the plant has processed more than 3 million automatic transmissions with a documented zero field PPM record and holds IATF 16949:2016, ISO 9001:2015, and ISO 14001:2015 certifications.

ALD Tratamientos Termicos generates revenue through B2B contract heat treatment services, charging per-batch or contract-based toll-processing fees for automotive transmission and drivetrain components as well as mechanical engineering parts (dies, pump shafts, drive wheels). Named enterprise customers include General Motors (recipient of seven Supplier Quality Awards from 2014 through 2022), Linamar, Magna Powertrain, and Regal. Sales are conducted directly through dedicated account managers, with no intermediaries, and the facility is positioned inside the northern Mexico automotive manufacturing corridor to serve cross-border OEM supply chains under ALD's standardized quality management framework.

Revenue model

1. Contract Heat Treatment Services: ALD Tratamientos Termicos generates revenue through commercial vacuum heat treatment contract manufacturing services. Customers outsource their heat treatment operations to HTS Mexico, benefiting from ALD's state-of-the-art vacuum furnace technology without capital investment. The company processes automotive transmission components and precision parts at industrial scale, with production records exceeding 3 million automatic transmissions. Revenue is derived from processing fees per batch or contract volume, typical of toll heat treatment / contract manufacturing arrangements.

Functional benefit

Products and services

• Low Pressure Carburizing (LPC) Vacuum carburizing process at temperatures between 870°C and 1050°C (typically 920°C to 980°C) using Acetylene as the carbon source at 5-15 mbar pressure, providing precise carbon diffusion for case hardening of automotive and industrial components. Enables uniform carburizing even for complex shapes including bore holes and blind holes.
• Neutral Hardening in Vacuum Vacuum hardening process where components are heated under vacuum or convection using nitrogen or argon, eliminating intergranular oxidation and surface decarburization, reducing post-machining costs, and producing oxide-free, metallically bright parts.
• High Pressure Gas Quenching (HPGQ) Gas quenching at pressures up to 20 bar using nitrogen or helium in a separate, cold quench chamber, providing lower and more reproducible dimensional changes compared to conventional oil, salt, or polymer quenching, with 99% Helium recovery and elimination of post-quench washing.
• Vacuum Annealing Stress relief and recrystallization annealing in vacuum, providing oxide-free and decarburization-free microstructure with bright metallic surfaces for automotive and industrial components.
• Cryogenic Treatment Deep freezing at -80°C using liquid nitrogen to transform retained austenite to martensite, reducing distortion risk and improving dimensional stability in precision components.
• Tempering Post-hardening process to adjust hardness-toughness ratio, available under vacuum or air atmosphere depending on component specifications.
• Nitriding Nitrogen diffusion process for surface hardening of components, performed in 2 dedicated nitriding furnaces at the Ramos Arizpe facility.
• High Temperature Vacuum Brazing Brazing process performed at temperatures above 900°C in a vacuum environment, producing metallurgically clean joints without corrosive flux residues.
• Thermal De-oiling Pre-treatment process for powder metallurgy components to remove calibration oils from open porosity before vacuum heat treatment.
• Pre-cleaning Aqueous cleaning of components before heat treatment to remove lubricants, coolants, cutting fluids, or rust preventives that could affect treatment quality.
• Rust Protection After Treatment Corrosion protection services including oil conservation, VCI paper, or VCI film packaging for temporary protection during storage and transport.
• Shot Peening and Shot Blasting for Deburring Shot peening and blast cleaning services for stress relief and surface preparation, plus deburring to remove sharp edges and burrs from machined components.
• Metallography and Related Analysis Material analysis services including surface hardness, case depth, microstructure evaluation, and carbon content determination to verify heat treatment results.
• Geometrical Inspection (Distortion Analysis) Dimensional inspection services including gear measurements, runout testing, and complete gear analysis to quantify heat treatment distortion in customer components.
• Heat Treatment Consultancy Technical consulting services for heat treatment feasibility assessment and trial treatments with laboratory evaluation to support customer engineering teams.
