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, Reaction Injection Molding can greatly help you to reduce unit price of each prototype. The biggest advantage of Reaction Injection Molding 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.

Reaction Injection Molding 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 Reaction Injection Molding 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 Reaction Injection Molding
1. Reaction Injection Molding Mould 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.
Reaction Injection Molding 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 Reaction Injection Molding process can reach your desired colors and surface effect without any polishing and spraying paints.

1. What type of 3D files do you accept for quoting?
We accept 3D CAD files in PRT, STEP, IGES, X_T, SLDPRT format. A 3D CAD file with STEP format is preferred, which can truly reflect the structural integrity of the 3D model and there will be no cracked surface.
2. Why surface treatment should be specified before quotation?
There are three kinds of surface treatment effects of prototypes: gloss, matte and sand surface. The sand surface effect has various specifications. For example, MT-11010 and MT--11020 are two different surface effects. The gloss effect requires the longest polishing time, resulting in more manufacturing costs.
3. What is the payment method of Leecheer?
When you chose Leecheer’s prototype manufacturing service, a deposit of 50% of contract amount should be paid to us. Then we will arrange production. After the completion of prototypes, we will take pictures of the prototypes and send them to you for review. If you have no problems and pay the remaining 50% of the contract amount, we will arrange shipment after receiving payment vouchers.
