Small output Polyurethane High Pressure Machine

Swiss Precision combined with Linden Control Technology - an unbeatable combination!
Small output High-pressure Mixing and Dispensing Unit for Open/Closed Mold Pouring

The PSM 90 is ideal for specialty applications that require a small shot size of polyurethane. This high-pressure machine provides 100% flexibility in processing Polyurethane foams, elastomers, and polyureas. The PSM 90 utilizes high-pressure cylinder metering for highly accurate shots as small as 3 grams (see video) and throughput as low as 10 grams per second. Precision cylinder technology combined with closed loop processing provides the ultimate equipment designed for precise metering accuracy. The PSM 90 allows the molding of complex, technical parts in both open/closed molding processes.
