Deflashing Thermoset Parts

Comments Off on Deflashing Thermoset Parts

While thermoplastic and thermoset molded parts may appear similar, one difference between molded parts is that thermoset parts are molded with excess material or “flash”, and must be deflashed after they are molded, whereas thermoplastics are molded without excess flash. Flash is excess molding material needed in thermoset molding to fully form a part and avoid bad or rejected parts. In order to mold a full part, thermosets must be molded with excess material flash, otherwise the part integrity may be jeopardized by shorts, burns or other molding defects. Regardless of whether a molded thermoset part is molded into basic or complex geometries, it will always require a secondary deflash operation. Removing the excess flash can be done in a variety of ways, depending on what is most suitable to the part and volume requirements. (more…)

Molded Thermosets for Kitchen Appliance Products

Comments Off on Molded Thermosets for Kitchen Appliance Products

Thermosets are used in products in a variety of industries. Electrical and automotive are two heavy users of molded thermoset components due to thermoset materials durability and protection against high temperatures and electrical current. Another industry that relies on the unique properties of thermoset molding materials is the home and consumer appliance market. Whether a product is a larger home appliance, or countertop cookware appliance, molded thermosets are used for elements and components touching high operating temperatures or requiring protection against electrical elements.

Converting Parts from Metal to Thermoset

Comments Off on Converting Parts from Metal to Thermoset

Engineers and product designers convert the design of existing parts and components from metals or to thermoset plastics in applications for a variety of material property advantages and benefits to the application. While metal components may require costly secondary machining operations to manufacture a part, thermosets may be molded into complex geometries and shapes. Incorporating thermoset materials into a product design may allow for consolidation of multiple parts of an assembly, as well as reduce overall weight of a product or assembly compared with metallic parts. For high-volume applications, thermosets offer a highly scalable solution to meet increasing product demand and volume requirements with low waste. (more…)
