GET A QUOTE also called Urethane Casting VACUUM CASTING

Vacuum casting could be a great way if you have a limited budget for low volume plastic parts production, while 3D printing all of them are expensive.

 

Master model is usually CNC machined or 3D printed via SLA or SLS
Liquid silicone is poured around the master model and cured, once dry the master is cut from the mold to leave the cavity. Finally, the resin is poured into the cavity to create a production like replica.

 

Our prototyping partner facilities are well equipped for vacuum casting production along with all kinds of surface finishes, similar to 3D printing service.

 

We can provide a comprehensive quote including alternative production methods such as PIM (Plastic Injection Moulding), RIM (Reaction Injection Moulding) or CNC, so you can have a complete overview of all scenarios to decide which route is the best for your project.

Vacuum / urethane casting capability overview

Vacuum / urethane casting
Maximum part size Depending on the master model size
Typical lead time
3D Printing / CNC time + extra moulding time
Typically 7 - 15 days depending on quantity

When to use vacuum / urethane casting

  • High quality, precise and consistent plastic parts
  • Low volume production with fast lead time
  • First-to-market advantage while waiting for injection moulding tooling
  • Self-coloured parts
  • Production-like parts
  • Great range of materials
  • Rubber like parts and overmoulds

 

For very large plastic parts, consider RIM (Reaction Injection Moulding)

Frequent asked questions

How many parts can you get from a single mould

Depending on several factors, normally a urethane casting mould can yields 15 – 25 parts. Some geometry such as sharp edges or deep undercuts tend to shorten the lifespan of the mould. Some proprietary casting techniques can have an extended mould life up to 35 – 75 units
