What Is Rubber Molding and Ways to Make Rubber Molded Parts

Do you need to make models of rubber-like plastic parts? At HLH Prototypes, we understand the importance of prototyping to ensure high-quality end-use products. Our prototype services include vacuum casting, a versatile manufacturing process for self-colored rubber parts for rapid iterations, and market testing.

Our solution can deliver a wide range of products, from small gaskets and seals to complex bumpers and car parts. It’s cost-effective yet highly accurate and precise, making it ideal for various industries, including communication, automotive, medical, and consumer electronics.

Are you new to rubber molding via vacuum casting? Keep reading this blog for more insights on what it is and how it can help you make high-quality rubber parts.

Understanding vacuum casting

Also known as cast urethanes, vacuum casting can produce parts without production tooling, making it more cost-effective and fast. It’s among the prototype services we offer for making any rubber part, regardless of size. It’s for making a low volume of identical rubber-like components.

Here’s what’s involved in the urethane casting process:

  • We make the master model via SLS or SLA 3D printing or CNC machining, depending on your design’s complexity and specifications.
  • Once the master model is ready, we pour liquid silicone around it and leave it to cure.
  • After drying, we cut the master from the mold, leaving the cavity.
  • We pour your chosen resin into the cavity to cast and make the rubber part.

Why choose rubber molding?

Rubber molding is among our prototype services that can deliver precise components cost-effectively and with minimal waste. It can craft parts with complex shapes and designs without compromising durability. In addition, this manufacturing process is ideal for parts for demanding applications, as rubber is inherently resistant to harsh conditions, corrosion, and extreme temperatures.

At HLH Prototypes, we leverage the adaptability of vacuum casting to customize rubber compounds. This allows us to meet specific performance requirements, especially when working with sectors that value material resilience and precision, such as healthcare and automotive.
