Profiles cooling channels facilitate efficient heat transfer from the preform spherical radius and gate area to minimize crystallinity. One-piece cavities eliminate parting line coolant leaks, eliminate nozzle gate inserts, and allow for water cooling channels to be profiles to the shape of the preform. This alignment ensures concentric material distribution from the nozzle into the injection cavity resulting in less leverage on the cores during injection therefore, more accurate control of preform wall thickness variation. Preform mold cavities, nozzle housings and nozzles are also located by the same jig-ground bore diameters in the mold bases. To achieve concentricity between core and cavity mold halves, final mold base bore diameters are jig-ground.
Molding surface components are made of ASSAB steel, hardened and ground to 45 Rockwell “C” in addition, all cooling channels are electro-less nickel plated to prevent corrosion. We use only the best mold steel available. This simple feature can prevent hundreds of downtime hours per year. Molding surface components, Valve-gate assemblies and hot manifold components can be removed, serviced and re-installed without removing the mold from the machine.

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. Hot runner valve gate is applied no need to cut preform tail and it would save labor costs. 3.Off-center adjustment system to ensure preform thickness difference < 0.05mm. Self- lock and shut-off individually for each cavity to guarantee high precision and less defect of the final preform production. Mold base is chrome plated P20, and the chrome process helps avoid corrosion. Steel material: Mold main parts adopt S136 stainless steel, with high glossy surface finish and hardness up to HRC48-52.
PET PREFORM MOLD PROFESSIONAL
After-Sales Service Technologists professional in after-sales line and excellent credit assures stable operation of the mould.ġ. All of these increases processing precision, good interchangeability and low eccentricity ≤0.10mm (perform length≤100). Advanced Processing Equipment Many machine tools are imported from America and Japan, such as Machine center, CNC lathers, EDM and so on. German Vacuum stove is imported for heat treatment of the components, which assures the hardness of components HRC45-HRC48. plate method avoids corrosion efficaciously and assures long life service of the perform molds.
The main components of perform molds are made of S136 material (Sweden ASSAB). Reasonable- designed cold water channels increase cooling effect and shorten the cycle time. Advanced hot runner system assures lower level of AA value. No cutting of valve gate is employed to reduce the labor cost. We also design cold parts, hot runners and other main exchangeable components to fix on the imported perform molds. At the same time we can manufacture perform molds especially according to customers' injection molding machines. 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. Note: The thickness and weight of the 12 cavities pet preform mould are in accordance with the preforms,these measurements will change in case the products are improved.Ī.
