5 Galon Preform Mould

5 Galon PET Preform Mould

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.
