Structural thermoplastic foam-moulded parts are much lighter, with higher strength-to-weight ratio than solid plastic. The automotive sector is the main driver to structural foam growth as lifetime energy & CO2 savings drive the need for lightweight components. There is growing demand for foam mouldings, but there is a need for good surface finish.In the State of the Art, foamed parts are produced by a form of injection moulding using a chemical blowing agent or gas (HFCs, Butane, N2 or CO2). These foaming processes fail to achieve good surface finish due to low process pressure, heat absorption by blowing agent and bubbles forming at part surface, often with a characteristic swirl pattern preventing use of this technology for good quality surface finish parts.FoamTech Systems Ltd has been working on the technology to replace hazardous foaming agents with water and have tried several methods for introducing the water into the molten polymer in various ways and forms. The Watermould process has shown the most promise, and we are now in a position to develop the process further with the view to commercialising it and exploiting a growing market opportunity.

结构热塑性泡沫塑料模塑部件比固体塑料轻得多，具有更高的强度重量比。汽车行业是结构泡沫增长的主要驱动力，因为终身节能和二氧化碳节约推动了对轻质部件的需求。对泡沫塑料成型件的需求不断增长，但同时也需要良好的表面光洁度。在现有技术中，泡沫部件是通过使用化学发泡剂或气体（HFC、丁烷、N2或CO2）的注塑成型形式生产的。这些发泡工艺由于低的工艺压力、发泡剂的吸热和在部件表面形成的气泡而不能实现良好的表面光洁度，FoamTech Systems Ltd一直致力于用水代替有害发泡剂的技术，并尝试了几种方法将水引入熔融聚合物中，各种方式和形式。Watermold工艺显示出最大的前景，我们现在能够进一步开发该工艺，以期将其商业化并利用不断增长的市场机会。
