Vacuum Casting
Vacuum casting (also known as polyurethane casting, silicone mold casting) is an economical alternative to small batch injection molding of plastic parts.
It can be used to simulate the final molded part or finished product. Generally speaking, the mold is made of silicone rubber and uses CNC or SLA part as a main mode.
These molds replicate details and textures and give a consistent finish from one part to the next.

Advantages of Vacuum Casting

  • 01. Cost-effective prices thanks to the economic silicone mold;
  • 02. Rapid Prototyping with advanced equipment;
  • 03. Wide range of Material selection;
  • 04. High precision and fine details
  • 05. Excellent surface finish

Advantages of Reaction Injection Molding

Reaction injection molding (RIM Manufacturing) has the similar processes of vacuum casting for rapid plastic part prototyping. Compared to vacuum casting, reaction injection molding can be used to manufacture plastic prototypes with maximum dimensions of 2000 mm, and with varying wall thicknesses.

Materials for vacuum casting


(ABS is the acronym of Acrylonitrile Butadiene Styrene, which refers to acrylonitrile-butadiene-styrene copolymer) is a kind of thermoplastic polymer structure material with high strength, good toughness and easy processing and molding, also known as ABS resin .


PMMA is the abbreviation code for polymethyl methacrylate material. Commonly known as plexiglass, it is the most excellent and reasonably priced variety among synthetic transparent materials so far. Application: PMMA is soluble in organic solvents, such as phenol, anisole, etc., can form a good film by spin coating, has good dielectric properties, and can be used as an organic field effect transistor (OFET), also known as an organic thin film transistor (OTFT) The dielectric layer.


Polycarbonate (PC for short in English) is a high molecular weight polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the lower mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics.


Polypropylene (PP) is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, resistance to a variety of organic solvents and acid and alkali corrosion. It has a wide range of applications in the industry and is one of the common polymer materials. Australian coins are also made of polypropylene.
