Advantages of low pressure perfusion process

low pressure perfusion, also known as low pressure reaction injection molding ( Action Injection Moulding, RIM). It is a new process applied to the production of rapid die products. After mixing the two-component polyurethane materials, it is injected into the Rapid mold at normal temperature and low pressure, products are formed through chemical and physical processes such as polymerization, cross-linking, curing of materials. It has the advantages of high efficiency, short production cycle, simple process and low cost. It is suitable for small batch trial production in the process of product development, as well as the production of small batch production, simple structure covering parts and large thick wall and uneven wall thickness products.

RIM low pressure reaction injection is mainly used for small batch trial production during product development, as well as the production of small-batch production, simple-structure panels and large thick-walled and uneven wall thickness products. It is mainly used in medical and industrial product chassis, cabinets, trolleys, countertops, auto parts, automobile modification market, chemical containers, beauty, sports and leisure equipment, etc. , large and medium-sized plastic shells. It is especially suitable for small batch production with annual output of dozens, hundreds and thousands of pieces.

RIM low pressure perfusion process advantages:

has the advantages of high efficiency, short production cycle, simple process and low cost, it can be made into parts with different density, hardness and elasticity.

The molded product has good packaging effect and can meet the needs of design verification, structural testing and other purposes.

compared with VCM vacuum injection process, the molded product is larger in size, suitable for forming products with large wall thickness and no shrinkage marks on the surface.

The cost and cycle are significantly reduced compared to the traditional mold art and process.

Technical parameters:

applicable mold: resin mold (More than 100 pieces); ABS mold (More than 300 pieces); Aluminum Alloy mold (More than 1000 pieces).

pouring material: Two-Component Polyurethane PU.

physical performance: Similar to PP/ABS. The products have the features of aging resistance, strong impact resistance, high coincidence, easy loading and unloading, etc.

general working hours: 15- 30 minutes/piece, after demoulding, the part is cured at 80 ℃ for 2-Four hours.

standard replication accuracy: ±0. 20mm/100

The thickness of the pouring sample: The maximum pouring thickness is 10mm.

maximum pouring workpiece: 2000X1200X1000, 10KG
