Quick Overview of Liquid Silicone Rubber Molding

by Nice Rapid | Mar 08,2020 | Liquid Silicone Rubber Molding

The liquid silicone rubber molding process started in the 1970s when liquid silicone rubber has become a popular material for making rubber parts and products. It is the distinctive qualities of the process that makes it different from the traditional manufacturing process that involves silicone.

There are thousands of applications for liquid silicone molding encompassing a wide range of industries that includes automotive, infant care, medical, aerospace, electronics, general industries, and many more. Although liquid silicone rubber molding is used most in long and long-run productions, it is also used during the last stage of prototyping.

What are the characteristics of liquid silicone rubber?

The significant quality of liquid silicone rubber is its manufactureability, and it is the same reason why many industries are choosing this material for their products. And the process of liquid silicone injection molding has provided businesses with high-volume molding, straightforward processing, consistency on the quality of parts, and improve productivity.

Liquid silicone rubber also has the following characteristics that made it ideal for many applications:

  • It possesses biocompatibility with body fluids and human tissue. Liquid silicone rubber is impervious to the growth of bacteria, and it does not decompose other materials. Because it is odorless and tasteless, it passes FDA standards.
  • It can endure extreme temperatures.
  • It is chemical resistant.
  • It can be stretched, has high tensile strength, is flexible, and hard.
  • It has topnotch insulating properties.
  • It has natural transparency that allows pigmentation.

The Advantages of Liquid Silicone Rubber Molding

Liquid silicone rubber molding has many advantages, including:

LSR materials have allowed manufacturers to produce cheaper and high-volume production of many complicated parts using liquid silicone rubber molding.

Since the process of liquid silicone rubber molding is in a closed system, it presents little room for contamination. Besides, the process does not allow human intervention, and the materials are not exposed to the environment.

The whole silicon rubber injection molding process is using automated injection equipment, tooling, and ejection. It needs a minimal workforce to monitor the process, and there is no need for frequent changes in the materials.

Depending on the design and the characteristics of the end product, liquid silicone molding has less cycle time.

Automation of the entire liquid silicone rubber injection molding decreases the chances for accidents and burns and other concerns about safety.

In summary, liquid silicone rubber injection molding has allowed for cost-effective, consistent, and efficient production of parts and products that can be used in many applications.
