The feathers of our mould making are high precision, long service life, short cycle, reasonable price, timely deliver and excellent after-sale service. Our products are well received by theforeign customers. We Sincerely welcome new and old cilents both at home and abroad to cooperate with us principle for common development. Highly effective, the energy conservation, the environmental protection, the safe mould open and close the mould to pull out inserts the core and the threadtransfers the threadextension is my factory passes through one kind of new product which many years' development but independently develops, in domesticand foreign still was the blank. Usesthis to pull out inserts the core organization and thread rotation the thread rotation drawingof patterns organization, has solved the cylinde, the oil motor, the electrical machinery inproduction use flaw. This organization has stably pulls out inserts the core the machine capability, opens using the injection moulding machineGathers the mould the performance disposagble synchronization to complete the product to pull out inserts the core movement and revolves the movement. Compared with the original mould structure enhanced about the mould the pattern making time, saved gas and oil, the provinnce electricity, reduced greatly the production cycle Has solved the production safety problem which the injection moulding machine emergency exit closes.
