1. 2316 and 638 are used as mold materials to prevent rusting of molds and water holes;
2. The front and rear molds are made of heat-treated steel materials such as 2344, S136, DC53, GS767, etc., and treated to HRC48-52 to extend the mold life and prevent rust;
3. Some inserts in the front and rear molds, such as hot nozzle inserts, use S136 or 083 and heat treatment, while the bottom inserts in the front mold cup use S136, 083, 2344 and other heat treatment methods. The low top inserts in the rear mold cup, due to the high temperature near the hot nozzle and poor heat dissipation, use beryllium copper.
4. Because both the front and rear molds are made of independent columbium, the guide sleeve on the mold must be supported by 2510 and quenched to HRC48-52.
5. All guide pillars and sleeves are made of HASCO.
6. The mold hot nozzle is specified to use HUSKY, and the assembly of the hot nozzle should be notified to the manufacturer in advance to arrange for professional installation.
