Different from the traditional injection mould, the stack moulding has multiple cavities arranged in the mold clamping direction. It usually has more than one parting surfaces and there could be more than one cavity on each surface. It's equal to stacking multiple single level moulds together and producing on one injection machine. The stack molding technology is most suitable for large size flat product, shallow cavity shell product and small multi-cavities thin wall products.
Double the output while only increase 10% clamping force
Lower the cost of operation
No need for extra equipment
Shorten the mould manufacture cycle and lower its cost
As a well-known plastic injection moulding manufacturer in China, Jeward mould has an experienced mould design and manufacture team. We are specialized in stacking molding technology for shallow cavity shell product and large size flat product.
The injection points of stacking moulds are arranged in different parting surfaces. So, it's a great challenge for the hot runner system to inject resin to different surfaces. In addition, the middle part of stacking mould is too heavy to be held by a guide pillar. Therefore, each parting surface's plastic injection and the middle support of stacking mould are the key issues to solve.
Cooperated with top hot runner company YUDO, Jeward Mould adopts valve gate hot runner system to offer stable plastic injection solution. Also, to solve the middle support issue, our mould design team decided to use the support pillar system after discussion and analysis. This structure is highly stable and easy to maintain.
With the help of good hot runner system and support system, our stack mold operates stably and effectively. It brings our customers better economic benefit.
No, we could achieve stack molding with ordinary injection machine.
For the large size flat product, Jeward Mould uses cylinder and injection machine to achieve the ejection on two parting surfaces.
