Trexel Inc. [8] is often referred to as the industry standard for microcellular plastics with their use of MuCell® Molding Technology. Trexel, and other manufacturers of microcellular plastics, use both injection molding and blow mold methods to create products for applications such as automotive, medical, packaging, consumer, and industrial.
Cyclic microcellular foaming refers to the solid-state Microcellular plastic manufacturing technique in which the polymer is foamed sequentially. The concept was first introduced in a research article in peer-reviewed international journal, Materials Letters [ 1 ] on Acrylonitrile butadiene styrene as the base Polymer .
Micro injection molding is a molding process for the manufacture of plastics components for shot weights of 1 to 0.1 grams with tolerances in the range of 10 to 100 microns. This molding process permits the manufacture of complicated small geometries with maximum possible accuracy and precision.
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...
Direct injection expanded foam molding (also known as injection molded foam) is a manufacturing process that creates soft foam products direct from a compound into a final product. [1] This process eliminates the steps normally required for die-cutting and compression molding , because it manufactures the foam and the product, simultaneously.

The bubble/foam-making process is irreversible and endothermic, i.e. it needs heat (e.g. from a melt process or the chemical exotherm due to cross-linking), to volatilize a liquid blowing agent. However, on cooling process, the blowing agent will condense, which is a reversible process. [2] [3]
