Longwang provide controlled thermal processing integrated with CNC machining to ensure superior mechanical properties and long-term reliability for industrial applications.
Heat Treatment is a controlled thermal process used to modify the physical and mechanical properties of metal components after machining. It does not significantly change the geometry of the part, but it greatly improves internal structure, hardness, strength, wear resistance, and fatigue performance.
In precision CNC machining industries, heat treatment is widely used for aluminium alloys, carbon steel, alloy steel, and stainless steel components that require enhanced durability and stable long-term performance.
How Heat Treatment Works？
Heat treatment involves heating the metal part to a specific temperature, holding it for a defined period, and then cooling it under controlled conditions. Different cooling methods—such as air cooling, oil quenching, or furnace cooling—determine the final mechanical properties of the material.
Common processes include:
Annealing – Reduces hardness and improves machinability
Quenching – Rapid cooling to increase hardness and strength
Tempering – Reduces brittleness after quenching
Aging Treatment – Strengthens aluminum alloys through precipitation hardening

Advanced Surface Finish Options for CNC Machined Parts
Longwang provides multiple surface treatments to improve function, aesthetics, and long-term performance of precision components.
As Machined
Standard finish, surface roughness of 3.2 μm (126 μin), removes sharp edges and deburs parts cleanly.
Tumbling
Utilizes barrel or vibratory processes with abrasives to smooth and polish the surface of parts.
Heat Treatment
Alters the physical (and sometimes chemical) properties of a material to achieve desired mechanical properties.
Alodine
Chemical treatment process providing corrosion protection and surface preparation for paint adhesion.
