Urethane casting for rapid prototypes and low volume production – HY Metals Detail:

Urethane casting (1)

What is Urethane casting or called as Vaccum casting?

Urethane casting or Vaccum casting is a very commonly used and well-developed rapid tooling process with rubber or silicone molds to produce high-quality prototype or production parts in around 1-2 weeks. Compared with metal injection molds it is much faster and much cheaper.

Urethane casting is much more suitable for the prototypes and the low-volume production than the expensive injection molds. We all know the injection molds are quite complex,expensive,and takes weeks even months to finish. But for some prototype projects, you may have no so much time and money to budget. Urethane casting will be a great alternative solution.

How Urethane casting make parts?

Urethane casting is a rapid molding and copy process.

Step1. Prototyping

According to the 3D drawings supplied by the customer, HY Metals will make a highly accurate master pattern with 3D printing or CNC machining.

Step2. Make the silicone mold

After the prototype pattern is made, HY Metals will build a box around the pattern and add gates, sprues, parting lines to the pattern. Then the liquid silicone is poured around the pattern. After 8 hours of drying, remove the prototype, and the silicone mold is manufactured.

Step3.Vaccum Casting parts

The mold is then ready to be filled with urethane, silicone, or another plastic material(ABS、PC、PP、PA). The liquid material was injected into the silicone mold under pressure or vacuum, after 30-60 min of curing in a 60° -70° incubator ,parts can be removed from the mold which will be perfectly match the original pattern.

Generally, the service life of silicone mold is around 17-20 times.

So if the QTY of your order is 40 or more,we just need to make 2 sets or more same mold.
