Quality Molding Products for Various Types
of Thermoplastic Molding

When molding thermoplastic materials, you need the finished product to release quickly with minimal mold flow lines and a consistent finish. But 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 plastic injection molding operations deserve better products.

We've been creating molding solutions for the thermoplastics industry since the 1950s. We understand that 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 work closely with the thermoplastics industry to create ground-breaking products that reduce scrap and increase productivity.

Mold Cleaner

When you face molding operation issues such as discoloration, sticking parts, and decreased efficiency, you want to determine the root cause and correct it as soon as possible. A high-qualityB0B体育app下载from Stoner Molding Solutions will not only resolve these issues but also improve the effectiveness of your mold release agents and mold sealers.

A good mold cleaner will:

  • Remove contaminants
  • Reduce build-up
  • Improve molding efficiency
  • Leave no residue

Mold Sealer

Molds expand and contract during the thermal changes of the production cycle, which causes small cracks to form. When you don’t use ab0b体育appbefore applying your mold release agent, your finished product will have defects and stick to the molding surface.

Our mold sealers are:

  • Specifically formulated to improve the releasing of finished parts
  • 能延长模具的寿命
  • Designed to form a barrier between your tool surface and the thermoplastic resin
  • Created to work with our mold releases

Rust Preventative

In addition to our mold sealers' ability to extend the life of your mold, our rust preventatives can help too! When your mold is not in use—whether for maintenance, storage, or over the weekend—it’s at risk of年代ustaining damage from moisture, oxidation, and corrosion.Our rust preventativeswill effectively stop the rust from forming, so your molds will develop rust. We feature:

  • Short-term rust preventative—ideal for preventing rust overnight or during weekends
  • Medium-term rust preventative—ideal for rust proofing for several weeks
  • Long-term rust preventative—ideal for storing or transporting tools for up to a year

Industries Worldwide Rely on Our Release Agents

No matter what type of thermoplastic molding you do, we have a molding product for it! From mold releases with silicone and non-silicone formulations that provide an easy release tolubricantsthat reduce friction and make molding easier, you can count on Stoner Molding for several molding processes.

Injection Molding

Plastic injection molding 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 injection molding machinery—which is costly to repair—breaks down from excessive wear and tear. These challenges are why it's crucial tomaximize mold performancewith Stoner mold products.

Rotational Molding

Combining high temperatures and rotational movement, rotational molding can easily form an even-walled component. Some products formed through rotational molding include coolers, bins, 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 insert plastic film and sheet into a mold, extrusion molding moves melted plastic directly into a die. The die's shape—not the mold itself—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.

吹塑& 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 that build-up on molds can interfere with, increasing waste. You owe it to your team to optimize your blow and packaging molds with Stoner mold release agents and our other related products that are designed to reduce build-up and lubricant close points.
