Polyurethane Vacuum Casting

What is Polyurethane Vacuum Casting Services

What is vacuum casting (resin casting)? It is a highly versatile technology used for the production of small series of functional plastic parts. These parts are usually made of a wide range of polyurethane (PU) resins and cast nylon. Prototypes made in this way show great surface detail and fidelity to the original pattern. The polyurethane casting technique is ideally suited to low volume batch production when injection molding is not cost-beneficial.

There are hundreds of casting polymers available to reproduce any conceivable hardness and surface texture. These materials provide an outstanding variety of properties and offer the possibility to match colors and cast transparent components.

Vacuum casting is an extremely versatile method with many advantages such as low-cost and high efficiency. It is a cost-effective method for making a small number of rapid prototypes based on a master model. This method is suitable for plastic samples widely used in product testing, proof-of-concept, and display demos. At Tuowei prototype, from start to finish, our sophisticated vacuum casting technology, workflow, and professional staff can keep your project flowing smoothly to deliver exceptional molded parts and assemblies in a wide range of materials, colors, and finishes. We can provide you with premium plastic parts in the least time.

Advantages of Polyurethane vacuum casting

Polyurethane casting involves making a mold out of silicone rubber. It is usually based upon a master pattern created from CNC machines or one of our rapid prototyping services. Polyurethane vacuum casting is ideal for rapid prototyping or very low-volume production for the following reasons:

• Low initial cost. It does not require investment in expensive hard tooling

• High-fidelity of the mold. It gives excellent surface details, requiring little or no post-processing.

• It is an excellent way for testing multiple variations of a prototype design for rapid product development.

• Many different molding polymers are available.

• Once the master pattern is prepared, molds will be ready only in a few days.

• Molds are extremely durable, which can produce up to 30 copies.

• Different types and hardnesses of plastics can be molded together into a single unit.
