No. It can not share the same mould, PETG request the mould to use a different steel mould like it must be anti-rust steel mould material, like 2316 or S136.

The auxiliary mould is pushed out, or the machine pulls the bottom.

You can use pushing off or rotary cutting.

It depends on the product itself, normally containers smaller than 200ML, cycle time can control to 25s.

There is some common mould steel, such as P20/718/2738/2316/S136/ALU ALLOY The specialty is Al alloy has better cooling and is also very light. But it’s too soft and crispy, so life is not there.

The maximum mould thickness of the machine – the thickness of the actual mould is greater than the maximum width of the finished product, and it can fall off.

As long as the position of the corresponding air hole is marked to avoid the cooling water channel.

Center distance – Bottle diameter = Spacing (25MM minimum)

The number of cavities is arranged according to the injection volume, and the minimum number of cavities is 25MM.

Point gate, side gate.

Ejector pin demoulding, push plate demoulding, strong demoulding.

2083、2344、H13

The circular regular machine is an independent cavity.

The hardness range is 30-52, and the moving parts are generally soft. For example, the slider uses NAK80

“1. Save raw materials and reduce costs.
2. Shorten molding cycle and improve machine efficiency
3. Improve the surface quality and mechanical properties of products.
4. Point gate can be used without three-plate mold.”

The feed port of the hot runner and the mold interface are easy to leak glue.

Half of the flip cap is hard to do full hot runner.

Yes. Pulled-off sliders are easy to break

1. Without a tail gas seal, there should be no tail at all. The short tail is very short after the air seal, and the long tail is longer.
2. Some mold factories use precision machining equipment such as slow-moving wires and mirror sparks in mold processing. After each link is processed, they pass the three-dimensional inspection. However, after they make plastic molds, there will still be large jaws and assembly stage differences. Big and so on the defect. But our molds rarely have such problems. Because we understand the importance of these three-level positioning.
The accuracy of the mold cavity does not guarantee the production of good products. It must be considered from many aspects. If the positioning design of the plastic mold is unreasonable, it will cause problems such as poor mold movement, damage, and dislocation. In addition to the precision of the plastic mold, the mold base, the side lock, and the tiger’s mouth are collectively referred to as three-level positioning, which is a very important system in the plastic mold.

The reason is that the runner and PET material are not dry well
