Through Hardened
Undergoing quenching and tempering in a vacuum environment will not lead to surface modifications such as carburization, oxidation, decarburization.
The surfaces of the parts fetched from the vacuum furnace are smooth and clear. TSI adopts the vacuum heat treatment process for tool steel and power steel, allowing the surface and core of the workpieces to have the same hardness.
Through Hardened components are designed to provide uniform mechanical properties throughout the entire cross-section of the material. Unlike surface-hardening processes that primarily strengthen the outer layer, through hardening ensures consistent hardness from the surface to the core, helping improve structural integrity and load-bearing capability. This makes the process particularly suitable for screws and critical components operating under demanding mechanical and thermal conditions.
The vacuum heat treatment process also helps maintain dimensional stability and surface quality by minimizing oxidation and contamination during heating. As a result, workpieces retain a clean surface finish while achieving reliable hardness characteristics, reducing the need for additional surface treatment or post-processing operations.
Leveraging extensive experience in precision manufacturing and heat treatment technologies, TAN STAR INDUSTRIES INC. utilizes Through Hardened processing to enhance component durability, wear resistance, and operational reliability. This technology is widely applied to screws and other industrial components that require stable mechanical performance, long service life, and consistent quality in extrusion, injection molding, and other demanding manufacturing applications.
