48 cavity pet preform mould

Preform Injection Mold from 1-cavity for wide mouth jar and gallon bottle perform up to 72-carrow neck perform mold; Tube blank is designed with the help of computer, which surely contributes to the increasing of yield of bottle; Employed internationally advanced two-step dual taper locating technology. Each cavity self-locks independently to ensure low decentration of product; Core and cavity are made of special mold steel after preheating treatment in the original factory in Sweden. Individual tempera-ture control of each cavity; Lip cavity is made of imported nitrated steel, which is of high hardness and long service life, in accordance with international standard; The cavity is made of imported nitrated steel, which is of high hardness and long service life, in accordance with international standard; The excellent hot runner design assures uniform heating and improves greatly of the plastic product quality; No cutting of gate is employed to reduce the labor intensity; Standard inter-changeable mold components; The life of mold is more than 3 million times.I.Off-center Adjustment System Off-center adjustment system can make the error of preform’s wall thickness less than 0.05mm. This system does not affect the lifetime of mold; II.Self-lock System International advanced bi-awls fixed orientation self-locked structure has been adopted. III.Cooling System All the water Channels in the mold’s each inner part, which make the cycle time short enough. And all the cooling channels have been specially treated to prevent them from jam; IV.Heating System Double Heating System can ensure that the impact of heating is good and quality control is credible. The Heating Band unit makes nozzles be with invariable temperature. The Heater Unit is used to heat the hot runner plate with long using life and powerful heating capacity. V.Hot Runner System The perform mold adopt Pin-valve type Hot Runner System, such hot runner system can reduce mold’s each part’s wear & tear and maintenance cost, and also save 10% 15% electric energy; VI.Hydraulic Ejecting System The perform-doffing success ratio has achieved firm endurance and the whole perform ejecting process will become much quieter.
