3) PET Preform Mold Design

We designs not only preform with standard neck size for water preform, carbonated drink preform and oil preform, also design preform of special shape responding to customers request. We adopts a wide range of computer-aided engineering service from design conception to the finished products to make customer satisfied.

4)Valve-gate system

Our preform injection mold adopts an advanced valve-gate unit, which is used to control the molds injection point open & close on each cavity. Reliable sealing function, smoothing moving, low thermal expansion rate, and long using life are its main features.

Patent designed rectifying system for preforms wall thickness

The patent designed rectifying device is equipped to rectify the preform thickness during preform production. The preform thickness can be adjusted below 0.*5mm.

Heating system

PET preform mold with double heating system ensures perfect heating effect. It has separate temperature control mode: the heater bars are used to heat the molds manifold plate; the small heaters are used to supply the continuous heating temperature for cavity nozzle.

Cooling system

A specially designed cooling system with perfect cooling effect for each inner parts including core, cavity, valve gate system and necks. Perfect cooling system leads shot cycle time and higher output capacity.

Hot runner system

Preform injection mold adopts specially designed hot runner system to achieve ideal and prompt heating effect for preform production. Lager flowing channels of such hot runner system ensures the mold to produce preform with lower injection pressure, which reduces molds each parts wear & tear and maintenance cost, and also saves electric energy.

Steel material and machining tools

Mold cavity and Core are made of imported mold steel with fine polishing, high hardness and anti-corrosion to guarantee mold's high precession and good quality.
Digital Control Lathe, EDM, jig-boring machine and high-precision grinding machine have been used on mold machining. High machining precision and fast machining speed ensure UGOs high quality molds.

Heat treatment

After mechanical treatment, enhance steels strength and prolong mold service life. For example, we coat chrome on the mold plate surface for rustproof purpose and go on nitrogen treatment on neck part to increase its hardness. Special coatings also are available at our Machinery. With right operation, PET preform mold reaches 2.5 million shots.
