TAIZHOU DOUBLE WORLD PLASTIC&MOULD CO., LTD.

Mould Process:


Prep Stage：3D drawing checking，products mold-flow analysis, confirm best design concept, send 3D drawing to client for final confirmation.

Medium-term treatment: quenching and tempering to higher mold steel hardness

Post-processing: mold steel nitridation (making nitridation just need low temperature, less deformation without quenching, higher steel hardness to HV850, stronger wear resistance.

Mold making process: checking drawing---make mold steel ready---machining---mold base machining---mold core machining---graphite electrode pole machining---mold components machining---inspection---assembling---checking cooling system-mold test---samples sending---client feedback---mold packing---shipping

Packing:

 The movement components are coated with grease.

The sprue opening is blocked with butter

Mold lock stripper is installed, and its specifications meets the design requirements (three plate mold fixed to the B plate) at least two pieces.

Mold drawings, structural drawings, drawing of waterline layout, spare parts and mold material suppliers details, manual, packing lists, electronic documents.

The surface of PET prefrom mold should be painted (if any special requirements from customers, follow according to the contract and technical requirements)
