Reaction injection molding
What is Reaction Injection Molding?
Reaction Injecion Molding is to mix two-component polyurethane materials and inject them into rapid molds under normal temperature and low pressure environment, and form products through chemical and physical processes such as polymerization, crosslinking, and curing of materials.
Reaction injection molding technical parameters
Applicable molds
⦁ ABS molds (≥ 100 PCS)
⦁ Resin molds (≥300 pieces)
⦁ Aluminum alloy molds (≥1,000 pieces)
Pouring material
⦁ HD-PU4210
⦁ DCP-RIM
⦁ AXSON-RIM 875
Injection pressure
⦁ About 10MPa
⦁ Flow control: 600g/s
