I1. There are 4 cavities up to 72 cavities on PET preform mold. 2. Electric control system with simulating stretch testing improve yield rate. 3. Adopt world advanced dipole taper localization technique, each cavity self-clamp independently, ensure mold concentricity. 4. The material of mold die core and die cavity are made of Sweden special mold steel. 5. International standard screw neck, imported nitrided steel with high hardness is of long usage. 6. Advanced hot runner design and even heating temperature make sure the high quality of plastic products. 7. Valve gated type without tail reduces labor force. 8. At least 3 million guarantee. PET Preform Mold Design Mitstrong 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 customer’s request. Mitstrong adopts a wide range of computer-aided engineering service from designconception to the finished products to make customer satisfied. Valve-gate system Mitstrong series preform injection mold adopts an advanced valve-gate unit, which is used to control the mold’s injection hole open & close on each cavity. Reliable sealing function, smoothingmoving, low thermal expansion rate, and long using life are its mainfeatures. Patent designed rectifying system for preform’s wall thickness The patent designed rectifying device is equipped to rectify the preform thickness during preform production. The preform thickness can be adjusted below 0.05mm. Heating system Mitstrong series PET preform mold with double heating system ensures perfect heating effect. It has separate temperature control mode: theheater bars are used to heat the mold’s 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 and valve gate system of Mitstrong preform injection mold. Hot runner system Mitstrong series preform injection mold adopts specially designed hotrunner 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 mold’s each part’s 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 Mitstrong's high quality molds. Heat treatment After mechanical treatment, enhance steel’s strength and prolong moldservice 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 Mitstrong. With right operation, PET preform mold reaches 2.5 millionshots. After-purchase service Each set of PET preform mold undergoes strict mold trials before shipping from factory and attaches full set of parameter that is recorded depending on their own and sole serial number. Together withthe PET preform mold, full set of spare parts will be supplied for free to keep mold normal working. In the use of the PET preform mold, Mitstrong provides adequate spare part to any request and Mitstrong service department are very willing to provide technical support immediately for any possible request in any time.
