Process performance
About the mold production costs, the material costs generally account for 10% to 20%, while the mechanical processing, heat treatment, assembly and management costs accounted for more than 80%, so the mold material process performance is the most important factor on impact of mold production costs and manufacturing difficulties.
Q: How long could the mold be used?
A: In general, it will be used to calculate how many times of use, rather than years. The life of the mold depends on the durability of the materials, construction methods during manufacture, reinforced design and the thickness of the mold.
