A change of just 0.2mm can make all the difference. Overview Orifice Sizing plays a key role in determining mix quality of the 2 part polyurethane foam in a Reaction Injection Molding operation. Multiple factors contribute to the overall Injection Pressure of your system, and the orifice is the last stop before mixing. Each polyurethane chemical supplier provides a datasheet that should provide the ideal injection pressure for your chemistry. Other important considerations would be chemical...

Determining Pump Rotation can be confusing. This post examines how to confidently determine pump rotation for proper operation.

A Mix Head : The Heart of Polyurethane Processing Equipment A mix head is essentially the business end of a reaction injection molding (RIM) or polyurethane foam system. It is where two or more liquid chemicals meet, blend, and immediately head into a mold or spray nozzle. This process is crucial as it initiates the reaction and curing of the materials. 1. Purpose of the Mix Head The mix head serves several important functions: Precise Metering: It accurately measures the correct ratio of...
