Vacuum casting uses silicon moulds to create high-quality prototypes of plastic and rubber components using two-component polyurethane resins.
Vacuum casting, also known as Urethane casting or Polyurethane casting, utilizes silicone moulds to produce plastic and rubber components under vacuum. This highly adaptable manufacturing process can mimic injection moulding to create complex parts in polyurethane resins and cast nylon.
The vacuum process ensures high-quality, bubble-free castings with smooth surface textures and no blemishes. Vacuum casting is particularly valuable for rapid prototyping of injection moulding parts and should be considered when selecting rapid prototyping processes for plastic or rubber components.
- One of the most cost-effective methods for producing high-quality, low-volume plastic parts comparable to injection moulding
- Ideal for form, fit, and function testing during embodiment design stages
- Suitable for marketing, field user testing, and product design verification
- Wide range of urethane casting resins available to meet various design requirements including temperature resistance, surface textures, and hardness
- Materials available in fully opaque, translucent, or completely transparent options
- Can produce high-quality wax masters for investment casting to enhance intricate feature details

ABS plastic is a terpolymer of acrylonitrile (A), butadiene (B), and styrene (S). The relative content of these three monomers can be varied to create different resin properties.
ABS combines the properties of its components:
- Acrylonitrile provides chemical resistance, heat resistance, and surface hardness
- Butadiene contributes elasticity and toughness
- Styrene enables thermoplastic processing and improves electrical properties
This versatile, cost-effective material is widely used in mechanical, electrical, textile, automotive, aerospace, marine, and chemical industries.
