Rubber molded parts are used for a wide variety of products and industries. There are multiple processing methods and materials that can be used as well. If you require rubber molded parts and need to decide what to use and how to mold it, this will be a handy guide.
As stated, rubber molded parts are pervasive throughout many products and industries in the United States. Some of these include:
- HVAC
- Appliances
- Compressors
- Automotive
- Heavy Equipment
- Airlines
- Bushings
- Couplings
- Generators
Types of Molding
- Compression molding pours a pre-measured amount of material in a heated, lower mold cavity. When the top cavity is closed, the liquid flows through the remaining mold and takes shape.
- Transfer molding measures, heats and forces the rubber material into chamber. A plunger applies force to the material and presses it into the mold using a system of runners and channels. The mold is heated and then opened so that the product can be removed.
- Injection molding uses a reciprocating screw to force the material into a heated mold. Once again, the rubber is formed under heat and pressure. It is then removed and cooled.
Another important decision to make is the type of rubber that would be most useful. Here are some questions to answer to help you make a decision.
What is the budget?
What is the application or function?
Does the part need to meet any regulatory requirements?
Will the part be exposed to chemicals?
Are there any temperature requirements?
Some of these questions may or may not apply to your specific application of the function of parts, but they are important considerations. Rubber molded parts can be made with different materials and in different ways. Determining what you need and what your budget is will help you and your manufacturer ensure the best solution for you.
