1. Use Fushun electroslag remelting H13 or SKD61 material.

2. The inner hole grinding adopts deep hole internal cylindrical grinding, and the inner hole grinding does not connect the knife. It can be completed at one time, and the finish can reach more than 0.8; the external cylindrical grinding adopts through-mandrel grinding, and the roundness of the inner hole is the same as that of the inner hole. Axial degree, perpendicularity, etc. work 100% to meet the requirements of the drawings.

3. Heat treatment adopts vacuum high temperature quenching (1030°C~1050°C), secondary high temperature tempering (HRC42°~46°); surface treatment adopts glow ion nitriding (nitriding layer 0.25~0.30mm) , HV≥900~950 (equivalent to HRC62°~65°), the bottom layer has high hardness, high surface hardness, and the inner hole is not easy to be strained; it has good heat resistance, thermal fatigue resistance, and liquid metal erosion resistance.

4. The largest injection chambers we process are:

Ø101.6*167* within Ø40.

Ø260*1080*within Ø160
