Plastics encompass a wide array of materials and molding processes used to create finished parts. Typical injection molding involves heating thermoplastic or thermosetting plastic polymers and injecting them into a mold where it conforms to the mold cavity, cools and hardens. Other molding processes, like Resin Transfer Molding (RTM), involve injecting or spraying liquid thermosetting materials into a mold with reinforcing fibers, like fiberglass. Typical plastic molding can be done two ways: either by closed molding or open molding. In simple terms, plastic resin exposed to the atmosphere during curing is known as open molding, while that which is not exposed to air during curing is known as closed molding. Each type of molding has its place within the plastics industry, with advantages and disadvantages for each. Read more >
Osborne Company News and Industry Updates
Custom plastic parts require production methods and tools that can deliver with precision. If one measurement, trim pattern, or hole is off even slightly throughout that process, it can result in scrapped parts that don’t match customer specifications. Fortunately for Osborne’s growing group of leading original equipment manufacturers (OEMs), automated CNC machining services are available to ensure accuracy with every round of production.

It’s no secret that both thermosetting plastics and thermoplastics play a significant role in the world today, but with so many different material properties, it can be difficult to determine which one is appropriate for a specific application. How do you determine which material is best?
Two popular plastics with somewhat similar material properties are UHMWPE and pDCPD, both of which offer unique benefits to fabrication and the applications in which they are used. Below, we compare and contrast these two key players to help you decipher which will work best for your application. Read more >
For plastic molding projects, the quality and performance of a finished product start with its design. Several molding processes, like Resin Transfer Molding (RTM) and Reaction Injection Molding (RIM), are ideal for accommodating molded-in components that can improve both part quality and performance. Incorporating these composite materials can improve structural integrity or reduce secondary operations. When designed properly, complex plastic molded parts incorporating these components can result in lower production costs and higher strength. Read more >
Polydicyclopentadiene (pDCPD) is a highly engineered thermoset polymer with exceptional physical properties including chemical and corrosion resistance, impact strength, stiffness, and heat resistance. Perfect for rough and demanding environments, pDCPD is used in thousands of applications where large, strong, and aesthetically-pleasing parts are required.
The design freedom of pDCPD has virtually no limitation on part size or weight. It delivers the molding flexibility of a thermoset, but with characteristics similar to expensive engineered thermoplastics. Read more >
Reaction Injection Molded (RIM) components feature a combination of unique physical properties not found in thermoplastics or metal. Incredible impact and corrosion resistance makes RIM-molded thermosetting resins like polyurethane and polydicyclopentadiene (pDCPD) an excellent choice for original equipment manufacturer’s (OEMs) whose equipment must withstand harsh conditions. RIM plastics excel in high temperature, highly corrosive, and extremely abrasive environments.
Dear Customers, Suppliers, and Employee-Owners,
The novel Coronavirus, better known as COVID-19, has become a household word. Although we do not fully understand its future within our company nor the economy, we do understand and support those that are battling the virus on the front lines. Osborne is working to keep its business safe and steady to support any and all business as the many economies continue to re-open around the world. Read more >
One of the advantages of custom plastic molding is the ability to easily accommodate molded-in components. From brackets or threaded inserts to attach molded plastic parts to finished equipment or cores to add structural integrity to a part, the RTM (Resin Transfer Molding) and RIM (Reaction Injection Molding) processes are well suited for molded-in components.

Molded thermoset plastic products offer numerous advantages over other plastic molding processes, including outstanding structural rigidity and strength and lower tooling costs. The molding process is crucial to reap the rewards of these advantages, but the properties of the materials used, like fiber-reinforced polymer or fiberglass-reinforced plastics (FRP), are what make these finished parts a success.

Comprehending the difference between thermoset vs thermoplastics, and which applications are suitable for each type, is often confused. Though thermoplastics and thermosets may seem similar, they actually have very different properties, and thus, industry applications. The differences between these two polymers are significant enough that understanding the behavior of each can ultimately help improve product designs and decisions.
Osborne Industries breaks down the differences between these two types of well-known polymers. Read more >
