MuCell® Microcellular Foam Molding System
We use a physical foaming method in which supercritical gas is directly dissolved into resin. This molding method has high foaming properties and a wide range of applications, enabling the production of injection molded products that are lightweight and have good dimensional stability.

About MuCell® Microcellular Foam Molding
This is a physical foaming molding method that uses nitrogen or carbon dioxide extracted from the atmosphere directly to dissolve the resin. It has stronger foaming power than chemical foaming and is more environmentally friendly.

Features of MuCell®
Reduction of resin usage
Foaming of resin can reduce weight and the amount of resin used. In addition, foaming can prevent sink marks, enabling unprecedented designs, and reducing the volume of molded products can further reduce the amount of resin used.
Improved warping and sink marks
Since the foaming of the resin replaces the pressure holding, it is possible to prevent sink marks. In most cases, setting a rib with the same thickness as the base wall thickness will prevent sink marks from occurring on the molded product.
In addition, since pressure holding is no longer necessary, warping caused by pressure holding can be improved.
Increased Productivity
Since foaming prevents sink marks, this molding method does not require pressure holding. This allows the clamping force to be reduced by approximately 50% (when the weight reduction rate is 10%), which allows the clamping tonnage of the molding machine to be reduced.
Also, with the same molding machine, you can double the number of molded parts. In addition, you can shorten the cycle time by reducing the time required for the pressure holding process.
