Heat Treatment

Heat treatment is a method to change the hardness and sometime chemical properties of material. Suitable heat-treatment is the balance between cost and life-durability.

Tien-I have three main types of heat treatment:
- Continuous Heating Furnace
- Batch Heating Furnace
- Vacuum Heat Treatment Furnace

Heat Treatment
Environmental Friendly Plating

The surface treatment improve durability and appearance. However, the traditional plating may cause serious environmental issue.

We hope to supply the products with quality as well as green.

That's why Tien-I choose the qualified plating factories complying with the government environmental regulation and international ROHS requirements.
