Low pressure perfusion, also known as low-pressure reaction injection molding ( Reactian Injection Moulding, RIM ) is applied to the rapid production of a new process, it will double component polyurethane material through mixing, at room temperature, low pressure injection mould under the environment of rapid, material through the polymerization, cross-linking, curing and other chemical and physical processes forming products. With high efficiency, short production cycle, simple process, low cost advantages. Suitable for the process of product development trial production of small quantities, and the product has the advantages of simple structure and large covering parts of thick wall and uneven wall thickness products of small batch production.
Technical parameters:
