Thermoset Molding

Thermoset MoldingWith decades of thermoset molding experience and expertise, Woodland Plastics specializes in thermoset injection molding of Phenolic, Bulk Molding Compound (BMC), Epoxy, and DAP materials with press tonnage from 80-500T. Our customers rely on Woodland Plastics as a preferred thermoset supplier for molded components and assemblies within a variety of industries including the appliance, electrical, automotive, energy, and industrial markets that require parts and components to withstand aggressive and challenging application environments. Such environments suitable for thermosets may include high and intermittent operating temperatures, electrical environments, corrosive environments, outdoor and UV exposure, and applications exposed or submerged in chemicals, oils, and/or automotive fluids. Woodland Plastics has equipment and capacities in place to offer molding processes of injection, injection-compression hybrid, and insert molding of thermosets.

Whether a product assembly is completely new to the market, or an existing project exploring a material conversion from a metal or thermoplastic to thermoset; Woodland offers thermoset molding capabilities to alleviate product pain points, reduce manufacturing costs, consolidate the number of parts in an assembly, and improve overall product performance. Implementing molded thermosets into a product assembly allows OEMs and engineers are able to protect internal components and product assemblies from degradation or failure.

High Heat Stability

Customer Pain Point – Components or product assemblies may degrade or disfigure while exposed to high heat and high operating temperatures during application use.

What Thermoset Molding Provides – Heat resistance, temperature deflection, & dimensional stability up to 500° Fahrenheit and above.

Why Partner with Woodland Plastics – With extensive thermoset molding experience, Woodland Plastics manufactures heat-stable components that remain dimensionally stable even within high operating temperatures.

Chemical Resistance

Customer Pain Point – Product application may be exposed to oils, automotive fluids, or even rainwater run-off including salts or other chemicals.

What Thermoset Molding Provides – With excellent chemical resistance and stability, thermoset product assemblies and internal components will not corrode, nor be affected physically when exposed to harsh chemicals, fluids, or other challenging environments.

Why Partner with Woodland Plastics – Woodland Plastics has decades of experience molding for a variety of customer and product end-markets including for product applications exposed to oils, fluids, salts, and moisture.

Metal-to-Thermoset Conversion

Customer Pain Point – Metal components are costly and may require secondary operations such as machining and finishing.

What Thermoset Molding Provides – Consolidation of multiple parts of an assembly. Elimination of costly secondary machining or painting operations.

Why Partner with Woodland Plastics – Woodland Plastics offers integrated manufacturing solutions with support in engineering, tooling, and material selection to efficiently convert customers’ existing metal components or product assemblies to thermoset to drive product performance and lower manufacturing costs.

Lightweight, Cost Efficient

Customer Pain Point – Component assembly needs to be lighter to reduce overall cost of an assembly.

What Thermoset Molding Provides – Lowers component or product assembly weight over metallic applications without compromising product performance.

Why Partner with Woodland Plastics – Woodland assists with customer light-weighting efforts and leverages approved suppliers for tooling and material selection, keeping overall manufacturing costs competitive against metallic or thermoplastic components.
