Molded rubber goods can be created using a variety of processes. One process for creating molded rubber goods is Liquid Injection Molding (LIM). Liquid Injection Mold involves using Liquid Silicon Rubber (LSR). LSR has a high bio-compatibility, making it especially well suited for making molded rubber goods for the Medical Industry.
In the LIM process, two components that are the consistency of toothpaste are mixed together with precision, and then pumped into a part of an injection machine. Here, it is cured or vulcanized. The final component is ejected from the machine and packaged.
Using LIM to create molded rubber goods is very cost-effective. It is also a very clean process with a fast cycle time, making it possible to create large volumes of molded rubber goods. In addition, LIM is fully automated, which results in a greater product consistency.
Injection molding can also be used to create molded rubber goods. In this process, molten rubber is injected into a mold using a high amount of pressure. The mold, however, is in the inverse shape of the desired final product. Injection molding can be used to create very small or large molded rubber goods.
Compression molding can also be used to process molded rubber goods. With compression molding, the rubber is usually preheated, then placed inside an open mold cavity, which is also heated. The mold is then closed and pressure is applied. This forces the rubber to make contact with all of the mold areas. The heat and pressure are maintained until all of the rubber is cured. Compression molding is capable of creating high volumes of molded rubber goods and is good for creating molded rubber goods that need to have a high strength.
Some molded rubber goods include rubber bands for a variety of purposes, including large rubber bands used in industrial packaging. Molded rubber goods also include tubing and other components for medical use, seals, and o-rings.
