Compression molding is a molding process in which a preheated material is put into a preheated compression mold. The mold is then closed and the temperature and pressure are used to force the material to fill all areas of the mold and harden the material before ejecting the product. The product may contain flash, which can be cut off. Compared with several other molding methods, there is no runner and gate system in the compression mold. Compression molding has the ability to make complex parts without having to spend too much time and steps processing the parts, while putting part cost and turnaround time first, so for manufacturers in many industries, compression molding is a an advantageous process.
The compression molding process can produce parts of varying length, thickness and complexity. The strength of the objects it produces is also high, making it an attractive process for many different industries.
Thermoplastic and thermoset composites are the most common types of materials used in compression molding. MDC has experience with the following compression molding materials:
compression molding process includes four main steps:
When using compression molding methods, the following factors must be considered:
Compression molding application
Automotive part molds are the most common compression mold, Composite moulded automotive parts are lighter and stronger. In the construction industry, molded parts are more accurate and more durable...
