Plastic is a synthetic material created from a broad range of organic polymers that have become an indispensable part of our everyday world. The properties of plastic are numerous. For the most part, they are:
- Lightweight with a high strength-to-weight ratio
- Can be manufactured inexpensively and mass produced
- Water resistant
- Shock resistant
- Thermally and electrically insulating

RIM, or reaction injection molding, was developed in the late 1960’s. Over time, technology has evolved along with the RIM manufacturing process itself, allowing Osborne Industries to tap into the numerous and unique benefits and capabilities of RIM for a wide variety of products. RIM produces thermosetting plastic resin parts by forcing low-viscosity liquid polymers into a design mold. The liquid material conforms to the mold’s shape, and after a chemical reaction, generates the end part. RIM is a very economical process for low-production volumes and large parts. It also provides manufacturers and designers with more creative opportunities and projects, as it can easily mold thin and thick walls in the same part. Below we examine the multi-stage RIM process.

The advantages of injection molding over die cast molding have been debated since the former process was first introduced in the 1930s. There are benefits, but also limitations to the method, and that, primarily, is need-based. Original equipment manufacturers (OEM) and other consumers who rely on molded parts to produce their goods, are looking for such factors as quality, durability and affordability in deciding which molded parts best suit their needs.

Plastics are generally tough, corrosion and chemical resistant, lightweight, easy to fabricate, and less expensive when compared to alternative materials like metal. As with any manufacturing material, there are advantages and disadvantages to the different properties each material might have. Although there are many impact resistant plastics to choose from, there are a few that excel in their respective applications. Below we discuss the potential for three of the most common impact resistant plastics. Read more >

Have you ever wondered what the difference between thermoplastic and thermosetting plastic is? Although both sound similar, they have very different properties and applications. Below we discuss the differences between thermoplastics vs. thermosetting plastic, their curing process, and the pros and cons to each. Comprehending the performance differences can help you improve your product designs!
Thermoplastic vs Thermosetting Plastic
Thermoplastics and thermosetting plastics are two separate classes of polymers, which are differentiated based on their behavior in the presence of heat. The material difference between the two is that thermoplastics can be remelted, while thermoset plastics remain in a permanent solid state once hardened. As a result of these physical qualities, thermoplastic materials have low melting points while thermoset plastic products can withstand high temperatures without losing austerity. Read more >
In 1976, Osborne Industries, Inc., originated and initiated the closed-mold molding process that was later known in the plastics industry as resin transfer molding, or RTM. The resin transfer molding process has been in use ever since. RTM is one of the best methods for mass production of composite parts. It is primarily used to mold components with large surface areas, complex shapes and smooth finishes. The automotive, industrial equipment and agriculture industries have used the resin transfer molding process for decades for these reasons.
Below we discuss a more detailed step-by-step of the resin transfer molding process and its advantages.

When we had a customer that was looking for alternatives to the sheet metal hoods on boring machines used in the construction industry, Osborne offered pDCPD reaction injection molding (RIM) as a solution to the problems they were facing. The wet conditions on many construction boring jobs led to excessive rust on the steel hoods, while the rugged environment dented and damaged the sheet metal. As opposed to steel, pDCPD offers an excellent combination of chemical and corrosion resistance, as well as outstanding impact resistance. These characteristics made the engineered thermoset polymer the perfect replacement for the sheet metal hoods. Read more >
What is pDCPD? pDCPD is the abbreviation for polydicyclopentadiene, a thermoset polymer plastic material. Thermosets like pDCPD are distinguished from thermoplastic materials, the other main group of plastics, because, unlike thermoplastics which revert back to liquid form under excessive heat, thermosets will remain in a post-cured form.
pDCPD and other thermosets resist melting because of the process by which they’re created: two dissimilar liquids are mixed together, creating high temperatures that foster cross-linking between molecular chains. This cross-linking contributes to thermosets’ heat resistance. Read more >
