While thermoset molding materials are used in a variety of end-use industries, one of the larger industry users of molded thermoset parts is within the electrical industry. Parts molded in a thermoset material not only exude excellent electrical properties to remain strong and durable over the life of a part, but the electrical performance properties of thermosets also enhance the safety of end products and assemblies. With superior electrical properties over many engineered thermoplastics, thermosets are an excellent, low-cost material choice for electrical parts or assemblies that may experience electrical voltage, elevated temperatures, or thermal shock. ...continue reading

What is required to produce an acceptable part with thermoset plastics or composites? Is a thermoset molded part ready to be packed or boxed right off the press as a thermoplastic molded part can? While thermoset materials give molded components additional performance benefits over thermoplastics, they usually require secondary operations to complete the parts prior to shipping to customers. Thermoset processors must be proficient and capable to handle an array of secondary operations to complete parts. Similar to thermoplastics, thermoset molded parts can be painted, pad printed, and tapped or threaded after molding, however there are also other potential secondary operations required to complete parts. ...continue reading

With a commitment to quality, Woodland Plastics leverages technology to improve its overall quality functions.

PMs can include anything from cleaning molds to advanced tooling work or repolishing and chrome plating. ...continue reading

As a performance-based molding material, thermoset plastics are widely used in various electrical component applications. Implementing a molded thermoset into a product design gives the product added protection against challenging electrical environments in which components and part assemblies are at the risk of degradation. Parts such as circuit breakers, electrical enclosures or housings, covers, relays, switches, insulators, and motor components rely on a strong molding material that exhibits strong dielectric properties, thermal shock resistance, corrosion resistance, arc resistance, and electrically insulating properties. ...continue reading

As engineers and designers continually try and maximize their product application’s performance, thermosets are becoming more attractive to implement into component designs and assemblies. Molding thermoset materials such as a phenolic or bulk molding compound (BMC) polyester or vinyl ester provides an end part with better protection against challenging and aggressive environments including applications exposed to high temperatures and heat. Whereas engineered thermoplastics such as nylon (PA6/ PA66) and ABS may degrade and disfigure when exposed to excessive temperatures, creating an opportunity for product failure in the field, molded thermosets offer heat deflection properties up to 500F and even above in some formulations to protect components from damage or failure. ...continue reading

As a performance-based composite, thermoset plastics are an excellent material choice for applications exposed to aggressive and challenging environments. One of the top emerging applications for thermoset molding is with electrical enclosure applications. Electrical enclosures are used in all kinds of industries and end-markets including Appliance, Energy, Lighting, Industrial, and Utility markets. Implementing a thermoset into your enclosure design not only provides stronger material properties and resistance to aggressive environments but can lightweight your application significantly and reduce overall program costs over a cast aluminum enclosure. ...continue reading

As a thermoset injection molder, Woodland Plastics partners with a number of customers in different industries and end-markets to manufacture their thermoset parts and components. The physical properties of molded thermosets allow parts to remain dimensionally and chemically stable even when exposed to aggressive and challenging environments. Outdoor applications with high UV exposure are one area where most traditional engineered thermoplastics may discolor or see diminished physical properties over time, potentially harming the integrity of the molded part or assembly. ...continue reading

In support of Woodland Plastics’ thermoset molding capabilities, we also offer secondary operations and sourcing services as a full turnkey supplier. Aside from thermoset molding, Woodland can source hardware and component items, and assemble finish goods in-house prior to customer shipments. Woodland Plastics understands managing a complex supplier base can be challenging, and as such we offer turn-key services to mitigate pain points in a supply chain for our customers. ...continue reading

Choosing the right molding process for your thermoset part may seem daunting, but generally there are indicators in the design and program end-use application that push towards a specific molding process. Like thermoplastics, thermosets can be injection molded or compression molded. Each molding process has its own benefits and disadvantages a thermoset molder and end-customer must understand and balance, before sourcing out a new tool build. Variables such as program annual volumes, material property requirements, part design geometries, and use of molded-in inserts can all affect whether a part is better suited to be thermoset injection molded or manufactured with another molding process. ...continue reading

Woodland Plastics is a custom thermoset molder, located in Addison, Illinois, a suburb of Chicago. Specializing in medium-high volume thermoset molding applications, Woodland Plastics partnered with an automotive OEM to provide thermoset phenolic valve body components for the automaker’s transmission plants. As the program started, it was very labor-intensive, with Woodland operators manually removing the plastic gate by hand using files. Not only was the hand gate removal process labor-intensive, but it also created discomfort for the operators. ...continue reading
