Reaction injection Molding for Electronics support parts

Made of Polyurethane rigid foam

Introduction of Reaction Injection Molding

RIM is the result of a reaction between two liquid components isocyanate and polyol as they

are injected into a closed mould at low pressure.

The two components are mixed together as they flow into the mould as a low viscosity

liquid and the reaction, which increases the temperature and the pressure

at the surface of the tool, forms the polyurethane part in the tool cavity.

Polyurethane resins for RIM have grown into a broad range of formulations with particular physical

properties for specific performance requirements.

Rapid types can produce virtually anything from flexible elastomer , to foamcore parts to

extremely rigid, solid and thin-walled Polyurethane components.

Parts can be supplied primed, painted or surface treated with graphics to simulate various

textures such as carbon fibre.

Values not absolute some may be altered.

Brief Introduction of Xingang Company

Our 15 years of experience in polyurethane molding allow us to manufacture from simple to

very complex custom parts. We are expert in designing and producing Low density flexible

molding PUR foam.

Our specialized equipment and unique manufacturing processes are also the key of our success.

Since we only produce custom parts, color, hardness and configuration are your own choice,

and at the limits of your imagination.

TIPS

Reaction Injection Moulding (RIM) can provide very large parts such as automotive bumpers,

and enclosures for medical equipment for instance

BENEFITS

Low-cost tooling for large parts

Short lead-times for large components

Low volume production components

Low capital investment.

Short or long runs

Minimum set up

Cosmetic surface finishing

Rigid foam buoyant water proof materials

Soft foam materials

High impact PP like elastomer

Encapsulation and over-moulding

Hollow components low weight

Company introduction

We are Specializing in the design and manufacture of custom molded polyurethane foam parts, we 

have various kinds of different formulations of raw material. 

Hardness from 3ibs to 60ibs on the shore A. Both available in C and D

Our 15 years of experience in polyurethane molding allow us to manufacture from simple to very 

complex custom parts.

We are expert in designing and producing Low density flexible molding PUR foam.Of courese we both provide Rigid polyurethane foam and polyurethane elastomer.

Our specialized equipment and unique manufacturing processes are also the key of our success. 

Since we only produce custom parts, color, hardness and configuration are your own choice, and at the limits of your imagination.

As we are able to design 3D parts, we can also print prototypes for evaluation before production. Tell us about your project and we will be happy to develop them together with you in order to 

achieveyour production goals.

RIM All Of the products are made by Reaction and Injection molding Craft

We are always achieving your high quality production goals

There are many advantages to selecting Xingang PUR Foam.It exhibits excellent shock absorption, 

high dynamic load capacity, excellent vibration dampening, noise reduction and the highest modulus 

of elasticity of all elastomers. This high performance urethane foam is SGS approved and has 

excellent abrasion and cut resistance. Our PUR foam also performs well in oil and solvent 

environments.

Xingang PUR Foam parts are available in custom molded shapes,as well as Very low density Flexible 

foam .
