Normally cooling lines and ejector pins holes are tooled by deep hole drilling tooling. As normal drilling machine tooling, holes may not straight. Therefor, especially for ejector pins holes, not allowed to be tooled by normal drilling machine.
After precise tooling finish and cooling lines and ejector pins holes ready tooled, moulds can be assembled and polished. Some home appliances mould need high shinning finish on the part surface, mould polish request is very high. Therefore this mould can't be polished by polishing machine, they need to be polished by manual. After that we take mould testing and provide client good performance trial samples for approval. Our testing machines are Haitian injection machines from small tonnage to large tonnage, including MA 160Ton, MA 250 Ton, MA 320 Ton, MA 470Ton, MA530 Ton, MA 800Ton, MA1000Ton.
Testing plastic raw material can be norminated brand and model number by client. Mould trial videoes and injection molding prameters will be provided to client by us.
