Pu Foam Molding Process. This process is currently the most widely accepted method for. In particular due to the low viscosity of PU material mold rotation technique is often employed to enable better foam material distribution in the filling and foaming stage. Annons Find Audited China Manufacturers of Bulk Pu Foam Ball Wholesaler. According to its mechanical properties PU foam products can be divided into two categories.
To the mould after filling so that there is sufficient cure of the foam moulding to allow early release from the mould. An endless variety of parts can be made using soft rigid or integral foam. They have lower bulk densities higher sag factors and permeable structures. Our PU processing technology is used for a variety of applications in many industries such as the sports and recreation and construction industries. There are basically 3 methods for PUR foaming. PU foams fall into two distinct categories flexible and rigid.
The injection method involves shooting the material into a mold at a very high speed.
The material shot into the mold is either in the form of liquid or in the form of hardened polyurethane droplets. Polyurethane PUR and PU is a polymer composed of organic units joined by carbamate urethane links. We support you throughout the entire process so that even the smallest details meet your specific production requirements. Simulation of Reaction Injection Molding Processes. This process is very long but it creates a material that can withstand many tons of force. This process is currently the most widely accepted method for.
