Enhance Your Plastic Molding Process with Quality Products


When molding plastic materials, you need the finished product to release quickly with minimal molding defects and a consistent finish. However, when inferior mold releases cause parts to stick to the molding surface or impact the product's dimensional stability, you waste time and money by having to scrap the parts and mold them again. Your thermoplastic and thermoset molding operations deserve better products.

Every molder wants to get as many releases as possible from each application—with less downtime and waste. That's why we at Stoner Molding Solutions have been creating molding solutions for the thermoplastics industry since the 1950s. We work closely with the Plastics industry to create ground-breaking products that reduce scrap and increase productivity.

Injection Molding

The thermoplastic injection molding process is ideal for high-volume, mass-produced products requiring thousands or even millions of parts, such as toys, kitchen utensils, medical devices, surgical equipment, bottle caps, and more. It is typically a cost-efficient, high-output, low-waste, and versatile endeavor. Challenges can come when thermoplastic injection molding machinery breaks down from excessive wear and tear. Our products help avoid these costly repairs and the downtime that will harm your bottom line. These challenges are why it's crucial to maximize mold performance with Stoner mold products.

Rotational Molding

Combining high temperatures and rotational movement, rotational molding can easily form an even-walled thermoplastic or thermoset component. Some products formed through rotational molding include Kayaks, coolers, bins, tanks, containers, road cones, and more. Rotational molding produces high-strength parts with very little waste, though it is a slower process than some other plastic molding operations. Choosing a mold release agent for plastic that keeps rotational molding operations moving efficiently is the key to success.

Extrusion Molding

While other plastic molding processes moves plastic into a mold, extrusion moves melted plastic directly through a die. The die's shape determines the resulting part's shape. This fact makes extrusion perfect for creating atypical cross-sections and guarantees a smooth finish on the end product. Preventing waste in extrusion molding is essential, and the right mold release agent, sealer, cleaner, and lubricant for plastic molding is central to that goal. Additionally, our coating products provide easier de-nesting of thermoformed parts which create internal cavities for extruded plastics.

Blow Molding & Packaging

Blow molding, designed for high-volume manufacturing of hollow objects, creates uniformly thin-walled products at a very low cost. It can be used to achieve shapes that injection molding can't support, but blow molding does require close tolerances where build-up on molds can interfere with, increasing waste. You owe it to your team to optimize your blow  molds with Stoner mold release agents and our other related products that are designed to reduce build-up and lubricant close points.

Thermosets and Thermoplastics: The Plastic Molding Families

The plastics molding industry can largely be divided into two types of molding: Thermosets and thermoplastics. These two families of plastic molding provide unique benefits and drawbacks to the created products. When you begin your journey towards scaling production, consider what category of plastic will best fit your production needs:


Thermoset plastic molding typically involves injecting a mixture of materials into a high-heat mold. This heat activates a catalyst that forms a permanent chemical bond. This type of molded part typically can’t be reshaped or recycled due to the chemical process, but the result is a heat-resistant and very durable item.

Thermoset materials include:

  • Epoxy
  • Polyester
  • Bakelite®
  • Polyurethane

While these products can be very strong and durable, the byproducts of the chemical reaction are Volatile Organic Compounds or ‘VOCs.’ Dealing with these byproducts is a unique challenge for molding at scale. However, less heat and pressure is required.


Thermoplastics are, in some ways, a simpler molding material. The base materials are melted down and injected into a cold mold. This is a 100% reversible and renewable process for most thermoplastics. Thermoplastic molding produces more flexible bodies and aesthetically pleasing surfaces on molded objects.

Thermoplastics include:

  • Nylon
  • Polycarbonate
  • Acrylic
  • ABS

Thermoplastic requires high heat and high pressure, which means the machinery involved can often require a higher initial investment than other processes. Additionally, the low heat-tolerance can restrict the reasonable uses for the produced goods.

Our molding products can help you maximize your plastic molding production. Thermoplastic and Thermoset molding products can present unique challenges in demolding, cleaning, and sealing. If you are a plastic molding company looking to expand your repertoire or create at a larger scale, come to the molding products company that knows how to enhance and build upon your process.
