Product Description

Short tail PET preform mould 

Mould Feature

  1. Injection System
     A. valve gate
         Short tail PET preform mould usually use an advanced valve gate unit for short tail PET preform mould, this special system can control the injection hole on each cavity, making it open and close, reliable sealing function, smoothing moving, low thermal expansion rate and long using life are all its main features.
 
     B. pin point gate
         Some customers will choose pin point gate for PET preform mould to reduce the costs.
         This is also many customers' good choice.
 
     C. direct gate
         Short tail PET preform mould with direct gate is much cheaper than moulds with other injection gate, but it will increase the labor costs to deal with the gate on products.
 
2. Heating System
Shuoqu usually use double heating system to ensure perfect heating effect on PET preform mould.
    It has separate temperature control mode: the heater bars are used to heat the mold's manifold plate;
    the small heaters are used to supply the continuous heating temperature for cavity nozzle.
 
3. Cooling System
    A special design of cooling system with perfect cooling effect for each inner parts including core, cavity and valve gate system of PET preform moulds.
 
4. Hot runner System
  Shuoqu adopts specially designed hot runner system to achieve ideal and prompt heating effect for PET preform production.
    Larger flowing channels of such hot runner system ensures the mould to produce preform with lower injection pressure, which reduces mould's each part's wear & tear, maintenance cost and saves electric energy.
 
5. Steel material and machining tools
    Cavity & core steel is imported mould steel with fine polishing, high hardness and anti-corrosion to guarantee mould's high procession and good quality.
     Digital Control Lathe, EDM, jig-boring machine and high-precision grinding machine have been used on mould machining.
     High machining precision and fast machining speed ensure Shuoqu's high quality moulds.
 
6. Heat treatment of steel
    After mechanical treatment, enhance steel's strength and prolong mould service life.
    For example, we coat chrome on the mould plate surface for rustproof purpose and go on nitrogen treatment on neck part to increase its hardness.
    With right operation, PET preform mould from Shuoqu can reach to 2.5 million shots.
