Streamoulding® is a process and equipment solution for light weighting injection moulded plastic products. It is new disruptive technology that uses water as opposed to gas or chemicals as the blowing agent adding it to the polymer in the nozzle rather than the barrel of the injection moulding machine. The equipment is low cost relative to competitors, retro fit, and is easily installed and moved between injection moulding machines.

The Streamoulding® equipment consists of a replacement mixing nozzle and a separate control plinth. To operate, it only needs compressed air and a single-phase power supply and a volt free connection from start of injection from the moulding machine.

The technology produces a cellular structure with a surface skin and will work across a range of unfilled and filled materials. Weights savings in the region of 8 -10% are typical given the right application. Additional benefits from cycle time reductions, clamp force reductions and energy savings are also typically achieved.

The surface finish produced gives a marbling effect which is typical of foaming processes. This can be improved markedly with the addition of rapid mould heating/cooling technologies.

ROI’s can be less than 12 months for some applications

Key markets are packaging and automotive generally with larger parts giving the best results and savings.
