Table of Contents What is Vacuum casting? Vacuum Casting (also known as Polyurethane casting) refers to the use of existing parts to make silicone molds in a vacuum state. Polyurethane, silica gel, nylon, ABS and other materials are used for casting in a vacuum state, so as to clone the same replica as the original

Table of Contents In the prototyping of plastic components, urethane casting and injection moulding are widely used. However, there are some similarities between the processes. Our customers are frequently torn between injection moulding — a common process in which molten material is injected into a metal mould — and vacuum casting, which uses less expensive

Table of Contents What is Urethane Casting? Urethane casting is a cost-effective way to create rigid or rubber-like plastic prototypes and end-use parts. It makes a limited number of castings with silicone molds rather than expensive metal tooling. It’s comparable to injection moulding, except the tooling is more flexible and soft. As a result, urethane casting

With the rapid development of the machinery manufacturing industry, the demand for molds is increasing. A more complex mold often requires a combination of multiple pieces, which is not only expensive and long, but also difficult to ensure dimensional accuracy. The production of silicone rubber molds solves the problems of long molding cycle and high
