hot runner 12 cavitie pet preform mould

hot runner 12 cavitie pet preform mould in China for the preform with PCO 1810 neck. The weight of the preforms is 21g, Cycle time is 20 Sec with general PET screw type of injection molding machine. It could reach 10 Sec with 3 stage post cooling system.The main components of molds ( die core, die cavity and screw neck) are made by injection process, which are made of special mold steel ( Germany steel 2316) after preheating treatment in the original factory in Germany. In this way, the mold with long life service and high quality can be used for 3 million shots without any maintenance, meanwhile, the wall thickness between max. Parts and min. Part is not more than 0.05mm. We adopt 12 cavities preform mold base of 50# steel and sliding block of 718# steel.

A. Capacity of Research and Development
Jinteng company has a powerful team for research and development, which is capable of manufacturing the perform molds with one cavity to ninety-six cavities including the injection system. At the same time we can manufacture perform molds especially according to customers' injection molding machines. We also design cold parts, hot runners and other main exchangeable components to fix on the imported perform molds.
B. Mould Features:
1. Features of the perform mold. No cutting of valve gate is employed to reduce the labor cost.
2. Advanced hot runner system assures lower level of AA value.
3. Reasonable- designed cold water channels increase cooling effect and shorten the cycle time.
C. Material
1. The main components of perform molds are made of S136 material (Sweden ASSAB).
2. The mold base is made of imported P20. plate method avoids corrosion efficaciously and assures long life service of the perform molds.
3. German Vacuum stove is imported for heat treatment of the components, which assures the hardness of components HRC45-HRC48.
D. Advanced Processing Equipment

16203753974759901.jpgMany machine tools are imported from America and Japan, such as Machine center, CNC lathers, EDM and so on. All of these increases processing precision, good interchangeability and low eccentricity ≤0.10mm (perform length≤100).
E. After-Sales Service
Technologists professional in after-sales line and excellent credit assures stable operation of the mould.

1. Steel material: Mold main parts adopt S136 stainless steel, with high glossy surface finish and hardness up to HRC48-52. Mold base is chrome plated P20, and the chrome process helps avoid corrosion.
2. Self- lock and shut-off individually for each cavity to guarantee high precision and less defect of the final preform production.
3.Off-center adjustment system to ensure preform thickness difference < 0.05mm.
4. Hot runner valve gate is applied; no need to cut preform tail and it would save labor costs.
5. Hot runner: one temperature zone controls one point temperature; it would prevent the white defects on the preform.Hot-runner heater adopt ltalian technology and ltalian famous brand components.
6. Experienced designers design preform mold according to the final bottle shape; preform thickness and height is reasonably and perfectly designed to ensure the final bottles weigh light but feel hard.
