Besides, proper heat treatment is able to upgrade some functions of steel.

2. Structural design : It's important to consider the shrinkage rate, cycle temperature, cooling system before manufacturing.

3. Machining : Reasonable process can greatly shorter the production time and save cost.

4. Standard parts

5. Assembly : Be careful the clean work, especially the water system and screw hole.
