RIM is the short name for Reaction Injection Molding. When your prototype required quantity is more than 50 pieces and dimension is larger than 1000 x 800 x 300 mm, RIM casting can greatly help you to reduce unit price of each prototype. The biggest advantage of RIM casting is that prototype can be different wall thicknesses and the maximum wall thickness can be 10mm, which Urethane casting and Plastic Injection Molding don’t have.

RIM casting material is made from two mixing PU materials which are difference in properties . At present, the common used materials are HD-PU4210, DCP-RIM and AXSON-RIM875. Prototype molded by RIM have similar property with PP material or ABS material, which is anti-aging, strong impact force resistance,high goodness of fit, easy to assemble and unassemble,etc.
Technical parameters of RIM casting
1. RIM Mold Material
Resin Mould — apply to manufacturing quantity above 50 pieces.
ABS Mould — apply to manufacturing quantity above 300 pieces.
Aluminium Mould — apply to manufacturing quantity above 1000 pieces.
2. Prototype wall thickness:the best casting wall thickness is 4-6mm and the biggest casting wall thickness is 10 mm.
3. Prototype casting accuracy : ±0.2mm /100mm.
4. The biggest casting dimension : 2000mm x 1200 x1000mm
5. Casting time of each prototype : 15-30 min/piece.
RIM Casting Service provided by Leecheer Company can help you finish prototype with small batch (500-1000 pieces) and large dimension in 20 working days, and ensure prototype deformation in a allowable range.The biggest advantage of Leecheer Company is that prototype manufactured by RIM casting process can reach your desired colors and surface effect without any polishing and spraying paints.

About delivery time,our company choose FedEx intl. Priority service for all prototype to ensure that customers can receive their prototype with the quickest way.
Below time table of FedEx is the shipping time from China to different countries.
1. Is it available to process one prototype with two materials?
Yes, we can process it through overmould.
2. How many prototypes can be copied from a set of silicone molds?
If the dimensional accuracy is high, 15 pieces can be copied. If the dimensional accuracy is not high, 20 pieces can be copied.
3. What is the shipment method of Leecheer company?
We ship FedEx when you did not specify any express company. Except that we can also ship UPS,DHL,TNT and EMS. For Asia countries, we ship Aramex or Bre-line.
