Gas-assisting technology can be used almost for all different kind of plastic products. For example to design and building plastic injection molds for Appliance, Automotive, Household products, Grocery products, OA products, etc..
Now there are upto 15%-20% molds can be gas-assisted technical involved, and the rate is keeping increasing.
In China, the biggest field of gas-assisted plastic injection mold is for home appliances. For example, in Japan, 90% of TV plastic parts with size above 64cm are to be formed by gas-assisted technology. While China produces around 95% of home appliances directly or indirectly for customers and end users all around the world.
Application of gas-assisted technology:
Gas-assisted mold can be used for almost all plastic materials except for those extreme soft ones and some of the thermoset plastics.
Based on different feature of the products gas-assisted technology mostly used, there are 3 main products categories included:
A) Plastic rod products ( such as handles with big thickness),
B) Plastic plate products which are easily be warped and big flat plastic parts with sectional melted plastic accumulation,
C) Special plastic products which are hard to be formed by conventional single injection processing.
Advantage by using gas-assisting technology for plastic mold:
1) Smaller clamping force is needed for same plastic part
2) Molding cycle time is shorter to form same plastic part comparing to normal single injection plastic mold
3) Reduce warping especially for big plastic plate parts.
4) Since smaller clamping force is required for same size plastic parts, it is possible to put the gas-assisted mold onto smaller injection molding machines for production. Therefore it can save plastic parts production cost.
However, the cost to design and build gas-assisted mold is higher than conventional single injection plastic mold. The cost difference is case to case. But for mass production parts with high volume, it is worthy to do the investment on good gas-assisted molds!
