Technologies and materials:

1. Reaction Injection Molding (R.I.M)

We make rigid Polyurethane parts of various sizes, 3mm thick or more, weighting up to 45 kg's in a single injection.

The technology is well-suited for molding complex geometries, tight tolerance requirements and high cosmetic specifications.

Parts can be made of foamed or un foamed materials, which include threads, painting and a high level of finishing.


2. Injection Molding Thermoplastic

Rational Systems are not restricted to RIM polyurethane only. We offer other plastic material molding

technologies, such as injection molding ,silicon casting and more, in order to provide you the optimal solution in terms of quality

and cost for your needs. ABS, PC-ABS, PP, POM, ULTEM, Soft parts TPU, TPE, Silicon, and more (done in our sites in China).


3. Functional Prototypes

Manufacturing of functional prototypes, small production batches, and one-off enclosure sets, by CNC and 3D printing.

Using variety of materials like PC, ABS comply with UL-94V0 for medical devices.

High quality, quick feedback and supply service and support along the process from design assistance to finish parts and delivery.

unique capabilities for large scale systems parts.


4.Composite Materials

Manufacturing of big parts or small runs, made from Polyester or Epoxy, reinforced with glass fibers .Done by hand layup. High quality finish.


5. Painting& Shielding:

Painting of plastic parts by wet spraying and air-drying.
