Polyurethane casting prototype

Polyurethane ( PU ) casting rapid prototyping

Polyurethane (PU) casting by China Prototyping Center

We offer low volume production by Polyurethane casting or vacuum casting (RTV)

PU resin casting is a prototyping technology used when you need a small series or short run of your 3d cad model made out of a PolyUrethane with properties close to real injected plastics such as ABS, POM ,PA or TPE's. Usually  series of 5-100 pieces will be run.

The process:

The first step of PU Casting process involves encapsulating/enclosing a master model in a liquid Silicone rubber. Than 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. (Material that have a hardness of  20-80 shore A hardness)

We can vacuum cast optical clear plastics (similar to PMMA plastic material).

And we can color the resin in your RAL or PMS color. Or paint it later

WHAT ARE THE ADVANTAGES OF Polyurethane casting?

The main advantages of this process are lower tooling costs and a quicker turn-around than traditional mould making (e.g. we can deliver moldings within days of receipt of the masters).

The products have an exceptional detail and accuracy.

Minimal shrinkage permits use of duplicates or sub-masters for multiple impressions, useful if originals are delicate. Flexible moulds and inserts allow significant undercuts, simplifying mould-making and containing costs.

First of all, we create your 3d models by CNC milling or machining, we use this subtractive method to make your idea real in all kinds of steel plastics steel brass copper or aluminum. Sometimes SLA is used to create a "mother model"

For small quantity volume parts we use RTV ( room temperature vulcanization) with silicone moulds. Rubber or plastic parts can be made out of one mould

 

Our advantages:

  • willing to deliver as quick as possible /AQAP
  • western management led by industrial designers who will advise you the right technology.
