What is Injection Molding Service?
Injection molding Service, as a way of rapid prototyping, is a manufacturing process for producing parts by injecting material into a mold. Injection moulding service can be performed with a host of materials, including metals, elastomers, and most commonly thermoplastic and thermosetting polymers. Material for the injection part is fed into a heated barrel, mixed, and forced into a mould cavity, where it cools and hardens to the configuration of the cavity. Then prototype is formed.

Why Injection Molding at RPWORLD?

Free DFM

With 16+years experience, Expert feedback and free DFM (design for manufacturability) analysis can be provided to shorten customer's development time, lower manufacturing costs and improve product quality.

Various Special Materials

Various special materials available, like high-performance engineering materials, heat-resistance material and biomaterial and so on.

Flexible Molding Solutions

Multiple types of molds are available, such as soft molds, hard molds, experimental molds, mass-production molds and the like.

Lead Time

Our lead time can be as fast as 1 week. Generally, it will take 2 weeks to 4 weeks. It can be shorter as it depends on specific situations.


Rapid tooling can be as fast as 1 week. It may take 2-4 weeks for the mass-production molds. We can not only assist our customers on mass production, but also provide low-volume production service for 5-10 years continuously.

Micro Injection Molding

Micro injection molding will be launched, which can effectively reduce the production cost of low-volume plastic injection and shorten the mold development time from 4 weeks to 1-2 weeks.


Robot arms application achieves fully automatic production, which guarantees the high quality and product consistency. They accelerate the production and shorten the lead time to 1 week or less.
As another option, RPWORLD offers the 2K injection molding process (overmoulding) for small series production. This multi-stage process allows not only the overmoulding of thermoplastic components, but also that of metals.
