WHAT ARE THE ADVANTAGES OF VACUUM CASTING?

The main advantages of this process are a much lower tooling costs and a quicker turn-around than traditional steel mould making. the lead-time to create casted models is around 7-10 days. The products have an exceptional detail and accuracy which comes close to the final injected plastic parts. Flexible silicone moulds allow significant undercuts, simplifying mould-making and containing costs.

THE PROCESS:

The first step of vacuum casting process involves encapsulating/enclosing a master model in a liquid Silicone rubber. This model is usually made by 3d printing, SLA  stereo lithography or CNC vowin.cn/en/News/news1251.html' target='_blank'>machining.

Then a vacuum is applied to the mould. The mould is then cured in an oven at around 70°C.

Once cured the mould can be split up in 2 or more parts, at which point the master model is removed leaving a mould cavity perfectly replicating the master model.

WHAT IS POSSIBLE WITH VACUUM CASTING?

We can make double or triple shot products, we can cast rubber or TPE or TPR like materials. (with 20-80 shore A hardness)

We can vacuum cast optical clear plastics ( same like PMMA) and we can use Inserts in the products. Click here for vacuum casted examples.For more information and for a quotation please email your cadfiles (in IGES, IGS STEP or Parasolid format) and detailed information,
