Our company is leading in manufacturing PET Preform Mould from single to 144cavities over 20years in China. Now let me show you our PET preform mould features.

1.Steel:

Cav/cor steel: we use S136 stainless steel, made in Sweden, the HRC hardness 48-52. This steel can be  anti-rust and acquire substantial accuracy and fantastic quality; excellent polish feature and make sure the mould guarantee time.

Mould base steel: DIN1.2311 with precise grinding machine with each plate thickness tolerance 0.015mm for  a plate size 500*500*400mm, the hardness 32.

2.Injection Gate

Injection gate: we use valve gate with hot runner system. In addition, I also know that some customer use short tail or long tail in the mould. But we don’t suggest do that.  

Vale Gate VS Short/Long Tail

Using valve gate with hot runner system: 1). It can save material;

2). It’s easily for material flowing and having beautiful surface;

3). It needn’t worker to cut down the tail, so that saving labor cost.

4). In the early stage, the mould of valve gate cost will be a litter higher than short/long tail mould.

Using short/longer tail: 1). It will be waste material than valve gate.

2). It has tail and need worker to cut down the tail,  so that increase labor cost.

3).  Short/long tail will be broken in the mould, later maintenance will be difficult.  

4) In the early stage, the mould cost will be cheaper.

3.Mould Guarantee Time

In China, most of preform suppliers offer the mould guarantee time is 2 million shots, but our mould gurantee time is 5 million shots, the quality guarantee time is 2 times longer than most of PET preform mold makers.
