Hot Runner Steel CNC  PET Preform Mould 40g 28mm PCO With 8 Cavity

Quick Detail:

40g 28mm PCO PET Preform Mold
8 Cavity
Hot Runner
Self-Lock
Core and Cavity Material: S136 or 2316

Description:

1. High quality mold material

As you known, material is the foundation of the mold, molds high quality should be guaranteed by the high quality material firstly. Aiming at the different characteristics, we adopted different material for different mold parts:

Core part and cavity part: Stainless steel(Sweden S136)

Neck part: High grade nitrogened steel(38CrMoAl)

Mold plate: 52# steel

Guide bar and guide cover: 20CrMo

2. 40g Preform Design

3. High precision tooling

We have advanced CNC equipment and various kinds of high precision mold tooling machine.

For Mold plate: The surface is machined through imported grinding machine, which will guarantee the parallel grade between the plates.

For guide bars hole: This part is machined through numerical boring machine or CNC(numerical milling machine),which will guarantee the high running precision of mold plates.

For core part and cavity part: After rough lathing, the parts will be tooled on high precision numerical lathing machine, which ensure the preforms shape and size as the same as our design exactly.

For cylinder and material mouth-sealing bar: The cavity of cylinder will be machined through inner-round grinding machine,and the material mouth-sealing bar will be machine on high precision coaxial outer-round grinding machine, thus our material mouth-sealing bar can run stably driven by the outside air pressure, at the same time, and the working life is prolonged.

4. Advanced heat treatment technical

The steels inner structure will have some different change under different heating or cooling condition, through which we can enhance the performance of material. And during the tooling course, the changing is effectively to eliminate the cutting stress, accordingly our work piece can get the excellent using performance.

Plate: Heat treatment is very important for mold, especially for the large m
