THERMOSET INJECTION MOLDS Thermoset Injection Molds for Industrial Switch Thermoset Transfer Molding
Thermoset Plastic Pros
The strong molecular bonds provide additional strength to the material, and in some instances, the inability for the plastic to re-melt can be a benefit. In general, thermoset plastics have:
Chemical Resistance: Due to their chemical bonding during the process, thermoset plastics are less susceptible to damage from chemicals and corrosion.
Thermal Resistance: Because these plastics cannot be re-melted, they have higher temperature resistance.
Higher Rigidity: They have an overall higher mechanical strength and dimensional stability due to the cross-linked molecules.
Thermoset Plastic Cons
While thermoset plastics have their strengths, they can also be weaknesses. This comes from not only their strengths but also their place in the industry in general.
Availability: Before injection, thermoset plastics are liquids. Between handing, the need for modifications or special injection molds, and the general decline of use, they may be more difficult to find suppliers that carry them.
Un-Recyclable: As mentioned above, thermoset plastics cannot be re-melted, and therefore cannot be recycled into new plastics.
Lower Impact Resistance: While thermoset plastics have higher strength, they have a lower resistance when it comes to impacts. While harder, it tends to shatter instead of flex.

Why Use Thermoset Molding?
Thermoset materials are generally stronger than thermoplastic materials due to the catalysts that are added to the base compound that cause chemical reactions at the molecular level, forming a harder, irreversible final form. Thermoset plastics cannot be re-melted, only ground and recycled as filler for different applications.
Thermoset molded products have electrical and thermal insulation properties, which make them ideal for electrical and electronic applications. They are resistant to corrosion and have high impact strength, depending on the resin, and are cost competitive with engineered thermoplastics. Using thermoset molding allows producers to maintain tighter tolerances during the molding process compared to similar thermoplastic materials.
