Wanlong has beenspending on new technology and innovation, in 2010, is already developing newtechnology of mould compression; It is an extension of the traditional formingtechnology. It can increase injection parts lingers length/thickness ratio;Using smaller clamping force and injection pressure; Reduce pressure insidematerial; And raise the productivity of machining.
Suitable for all kinds of mould compression molding thermoplastic engineering plastic products, such as large curved surface parts, thin walled, miniaturization parts, optical lenses,Automobile skylight, triangle window, etc. Now our company has been successfully applied in the TV sprocket plate, transparent panel. Mould compression technology in the process of clamping, dynamic model with a certain gap, gap of large injection molding machine, ranging from 1 mm to 20 mm. Completely to a certain volume of plastic injection mould, the mould is plastic volume contraction due to cooling, and then closed mold, from the outside with a mandatory force to make the product smaller size, and make the part shrinkage compensation, to get the required size and precision.
Die internal compression strengths:
1. Reduce cavity pressure
2. Reduce molecular orientation
3. Reduce residual stress
4. Reduce uneven contraction
5. Reduce birefringence
6. To overcome warp
7. To reduce density change
8. Improve dimensional accuracy.
