Our Vacuum Heat Treatment Services guarantee exceptional quality across various applications, from precise hardening to tempering and annealing. We utilize advanced materials to enhance the performance of components.
Tooling parts/components are heated in a horizontal state-of-the-art vacuum furnace above austenitising temperature and quenched at a predetermined cooling rate with the help of pressurized high purity Nitrogen gas. After quenching, multiple tempering heat treatment cycles are performed to achieve the desired hardness.
Our Solution Annealing services offer precision and reliability for a range of applications. This heat treatment process involves heating materials to a specific temperature, followed by controlled cooling, effectively eliminating impurities and enhancing material properties.
This service employs austenitic stainless steel grades, primarily from the 300 series. Our process involves heating the material to 1150 degrees Celsius, allowing carbon to dissolve into the solution. Swift cooling follows to maintain the carbon within the solution. This results in stainless steel in its utmost corrosion-resistant and ductile state.

Our Precipitation Hardening services offer a superior solution for enhancing the strength and durability of components. This specialized heat treatment process is tailored to precise hardening requirements, ensuring optimal performance.
Precipitation heat treatments strengthen materials by allowing the controlled release of constituents to form precipitate clusters which significantly enhance the strength of the component. This process is performed at temperatures ranging from 900 to 1150°F in a vacuum, inert atmosphere or air for hold times ranging from 1-4 hours. depending on the material and desired characteristics

Brazing is a metal-joining technique wherein a filler metal is used to join two or more materials by drawing it into the joint by capillary action. A filler metal is a material with a melting point lower than that of the materials to be joined. Vacuum Brazing is a process that creates high-quality joints under temperatures from about 800°C to 1150°C in a vacuum atmosphere. This also allows for the joining of different materials.
Vacuum brazing is a joining process used to connect materials, typically metals, through the use of a filler metal called a braze alloy. This method involves heating the base metals and the filler metal in a vacuum environment, where the absence of air prevents oxidation and contamination, ensuring a clean and strong joint.

Our Plasma Nitriding Services offer exceptional enhancements for a wide range of applications. This process increases the surface hardness of the steel and improves its wear and corrosion resistance properties.
This is a low-temperature process where voltage is applied between the parts to be nitride and the furnace wall. A glow discharge with a high ionization level is generated around the parts. On the surface area, directly charged by the ions, nitrides are formed and decompose, releasing active nitrogen onto the surface of the parts.

This service requires holding steel components at a temperature below zero degrees centigrade to obtain the required structure. The temperature used is usually between -70ºC and -90ºC and the process is always followed by tempering.
The materials are placed in a specially designed cold chamber, and the temperature is gradually lowered to the desired sub-zero temperature. This can be done using liquid nitrogen or other gases.
Once the materials reach the target temperature, they are held at that temperature for a specified duration. This soaking period allows the material's microstructure to undergo changes. After the soaking period, the materials are slowly brought back to room temperature. The controlled warming phase is essential to prevent thermal shock and potential damage to the treated materials.
Stress relieving is a thermal treatment process used to reduce internal stresses within materials, particularly metals. This method helps improve the stability, durability, and performance of components.
The material is placed in a furnace, and the temperature is raised to a specific level, typically below the material's recrystallization temperature but high enough to allow for stress relief. The temperature and soak time depend on the material type and thickness. After the soaking period, the material is slowly cooled down in the furnace. The controlled cooling rate helps prevent the formation of new stresses or cracks.
Vacuum sintering is the process of forming a single mass from multiple components, typically powder, by heat and/or pressure without melting the base materials to the point of liquefaction.
The material is placed in a furnace, and the temperature is raised to a specific level, typically below the material's recrystallization temperature but high enough to allow for stress relief. The temperature and soak time depend on the material type and thickness. After the soaking period, the material is slowly cooled down within the furnace. The controlled cooling rate helps prevent the formation of new stresses or cracks.
