  3. Product quality: product dimensional stability, compliance, product surface finish, product data utilization, etc.
  4. The use and protection of the mold: whether it is the most convenient to use, demould, and the production support time should be as short as possible;
  5. Protect the surface of the plastic mold: During the manufacturing process, the outer surface of the mold blank needs to be protected to prevent rust and scratches.
  6. Spray anti-rust agent: Before packing the mold, it is necessary to spray white/or colorless anti-rust agent to the inner mold. All mold surfaces must be cleaned and then buttered.
