48 cavities injection moulds for plastic pet preform bottle   

Introduction: 

    We complete mould making line, from the mould's design, processing, assemblage, test to perfect mould. The mould designed by AutoCAD system, PRO-Engineer system, Solidworks system etc. 

For the mould processing, we use precision machines and CNC machine.

For the mould assemblage, we have experienced workers who has more assemblage experience. With carefully work attitude and rich experience, make our mould quality better and better. 

For the mould test, our company also make all kinds types of injection molding machine, this is our excellent, as other mould company not have this advantage for good testing. 

For PET preform mould, there are 8 cavities, 16cavities, 24cavities, 32 cavities  48 cavitied  and 72cavitied for choice. 

PET material because of its exceptional performance, are generally used two-step molding process, by the preform injection molding machine to produce a 24-hour After cooling, the internal molecular structure of their re-arranged in an orderly manner, and blowing for the next step to create good conditions, so that more excellent blowing performance products. Such as the famous Coca-Cola Company is currently using this technology. Its production processes are as follows:

Characteristics of the production line

First: PET material→dehumidify→load material→injection machine→ preforms

Second: PET Preforms →heat preform → stretch → blowing → bottles

Cap on in the injection molding machine is completely automated production, its production process is as follows::

     PP material→load material→dry→heat material →injection→cooling molding  →preforms→cap

      Injection molding machine: Adopting Europe technology, hydraulic unit adopts proportional pressure and flow control, the pressure and the speed can be adjusted, stable movement curve and gentle shock, the computer is imported from Industry family. The LCD displaying screen with high clarity has Chinese and English language to use. Close-loop PID temperature control with the advantage of high precision. The operating table of the injection molding machine have two safety, one is machine safety, another is electrical safety, that ensures the operators’ safety.  

       Mould: Our mould producing center produces exact mould, adopts the high grade material to make. The perform mould uses the hot runner technology, inside uses the imported steel, the surface’s brightness is very high and the service time is very long.

1.The design of equipment is logical, easily operation.

2.The automatic level is very high, the wage is very little.

3.Using famous imported hydraulic, electrical, sealing parts, the trouble is low.

4.No matter what the product’s outside or inside, they can get the best guarantee, the good products rate can be above 99%
