HyperFoam High-Performance Foam Injection Moulding System

Horizontal Injection Machine

Products Name: HyperFoam High-Performance Foam Injection Moulding System

Features Specifications:

HyperFoam is a low cost breakthrough technology in chemical foaming agent based plastic foam injection moulding. HyperFoam can achieve: elimination of shrinkage, sink marks and warpage; dimensional stability; 10-30% of part weight reduction; and shortened cycle time. HyperFoam can achieve:

  1. Up to 50-60% clamping force reduction
  2. Reduction on operational power consumption
  3. Up to 10-30% part weight reduction

HyperFoam adopts high pressure injection principle. High pressure injection principle means fusing carbon dioxide gas, produced by chemical foaming agent with polymer melt under the supercritical state. When this supercritical fluid is injected into the mould cavity, HyperFoaming occurs with instantaneous cell nucleation takes place, forming a honeycomb like structural foam upon cooling. With the principle, HyperFoam is a completed solution for applying foam injection moulding to lower production cost and to make high quality foamed part in stable and accurate dimensions.

To execute this principle mentioned above, the intricate operation of a few accessories is required. HyperFoam operates with an endothermic (heat absorbing) chemical foaming agent, a nitrogen injection accumulator and a high pressure shut off nozzle. With these components work together, HyperFoam miraculously makes foamed plastic part consistent and reliable. HyperFoam can be used for manufacturing of automotive parts, electrical appliances, household products, electronic products, storage products, furniture, and many more application to be discovered.

HyperFoam is co-developed by Welltec Machinery Ltd. and China Venture International Ltd. This innovative technology is patent pending in China.
