Mold is used for the final molding of glass bottles. Cast iron with copper alloy material, the main ingredients: copper, aluminum, nickel, casting hardness is 210-230 - hb, adopting secondary melting process, ensure the stability of the material, the copper alloy mold material has a good size heat fatigue and high temperature stability, relative iron mould service life 5 times, it is mainly used for opening mold, mold, molding die.
The advantages of V method casting and V casting glass mould are adopted in mold casting.
1. Higher production efficiency: using V method casting process to produce glass mould, the shape is convenient, the labor intensity is high, the production efficiency is much higher than the traditional sand casting process.
2, better machinability: V method casting dimension precision, good surface finish, compact structure, provides us with better machining performance, small machining allowance, greatly reduce mechanical processing capacity.
Microstructure: 3, better than sand casting castings, V method casting d-type graphite organization can obtain more excellent and more excellent casting density, more advantageous to work in the process of glass mould heat.
