VACUUM CASTING

The Best Choice for Low Volume Production

Vacuum Casting is an extremely adaptable manufacturing process capable of mimicking the injection moulding to produce complex parts in polyurethane resins and cast nylon. The best choice for low volume production.

Applications of Vacuum Casting

Vacuum casting, sometimes referred to as Urethane casting or Polyurethane casting uses silicone moulds to make plastic and rubber components under vacuum. It is an extremely adaptable manufacturing process capable of mimicking the injection moulding to produce complex parts in polyurethane resins and cast nylon. Since sofe materials such as silicone and rubber cannot be manufactured by CNC Machining or 3D Priting, the Vacuum casting is adapted to produce that kind of materials. And it also apply to low volume production, because the mold can be used repeatedly. Normaly it can produce 15 some parts each mold.

Applications of Vacuum Casting

  • Vacuum casting is one of the most cost-effective ways to produce high quality, low volume plastic parts which can be similar to injection moulding parts
  • The parts are especially suitable for form, fit and function tests during the embodiment design stages, where they can be used for marketing, field user testing and product design verification purposes
  • There are many vacuum casting resins commercially available that can be used to create parts to satisfy a wide range of design requirements such as temperature requirements, different surface textures, hardness, etc.
  • Materials are also available to create parts that are fully opaque, translucent or completely transparent
  • Sometimes high-quality wax masters can be made using vacuum casting for investment casting to increase the finer details of intricate features

Advantages of Vacuum Casting

  • Multiple components can be used from the master pattern within 24hrs which would reduce the product design prototyping stage cutting time and cost on new product development
  • Vacuum casting can be used to create small batches of high-quality injection moulding type parts for prototypes or low volume end-use parts for low stress, relatively benign environments
  • A wide range of vacuum casting resins are available to suit various applications such as clear, rubbery, flame retardant, food-grade and coloured to suit
  • Resin type can be changed easily without the need to retool to test various material types for a given application or part
  • Complex shapes and features can be accommodated by using multi-segment moulds & cores
  • Aluminium and brass in-mould inserts can also be used
