Thermosets can be molded using compression or injection processes. Each process has a different field of application. Injection molding requires a large tooling investment. The material is injected into the mold from a hopper through a hydraulic filler and a screw. The glass fiber filler is chopped up and dispersed during the molding process. It is a popular process for thermoset parts.
Thermoset molding is a form of thermoplastic injection molding. It is a great option for manufacturing products that require high heat deflection and strength. A thermoset mold is capable of enduring temperatures of up to 150degC and 302degF. When used correctly, thermoset molding can yield the desired result in just a few days. Once the thermoplastic material reaches the mold, it can be cooled in a temperature as low as 150 degrees.
Thermoset molding processes have several benefits over thermoplastic molding. A thermoset mold forms a shape after it has been heated. The heated material is forced into the mold. This process is irreversible, so it reduces the possibility of a part being altered during molding. Thermoset molds are stronger and more durable than thermoplastics due to the addition of catalysts that cause chemical reactions at the molecular level.
Thermoset mold manufacturers use glass-filled phenolic material in their parts. Thermoset molds are easy to work with and have a range of properties that can be adapted to your specific needs. When choosing the right thermoset mold maker, it is best to consult a database or manufacturer of thermoset molds. Once you've done this, you'll be on your way to success!
