What is gas injection molding? |
|
|
- Suitable for thick or large products and widely used. It is a technology to inject nitrogen into the inside of a product to make a hole.
- Enhances discretion of product design, reduces cost and fortifies structural strength.
- Improves numeric safety and formability and reduces injection molding cost due to lowered tonnage.
- Here are benefits from product form.
- Easily applicable to products and short gas flowing distance.
But, it is hard to control uniform processing and the machine is very expensive.

Gas injection support status and trends |
|
|
|
In Korea, it was mainly applied to television –related areas. Recently, with the big size products in the mainstream, it is actively applied to OA equipment and automobiles.

|
- PFP gas injection molding technology is originally developed by NSCC.(1994)
- The major advantages are removing sink mark and residual stress with only very-low pressurized air.
- It is needed simple and cheap control system only.
|
|
|
 |
|
|
PFP reaction mechanism |
|
 |
|
 |
|
- Install a nozzle to a thick area of product.
- Fill resin with full shot forming.
- Void is created when air pressure to a nozzle gets higher than internal pressure.
- When volume is shrinking, void is created and then stops when resin is hardened.
|
|
 |
|
 |
|
 |
|
|
|
Void creation mechanism |
|
|
- Void is created when internal pressure is lower than the ambient pressure.
- Void grows with shrinking volume.
- The direction of void is decided by shrinkage.
So, it grows toward thick part or hotter resin.
- Void grows stops when resin is hardened by cooling.

Liquid Injection Process(Liquid Injection Process) |
|
 |
|
|
|
|
What is liquid injection process?
- While resin is flowing into a mold, a liquid easy to gasify is injected into a mold and absorbs residual heat from resin to gasify. It creates a void inside the product using the pressure generated by the gasification of the liquid.
- It is used to mold a thick product and its appearance quality is important. It is suitable for products with simple design.
