Custom Molding
Custom Rotational Molding
• Variety of Materials & Colors
The rotomolding process is a fairly easy process to understand. Plastic resin is placed into a hollow steel or cast aluminum mold, placed into an oven and rotated on two axes at a low speed. As the material heats, the resin starts to adhere to the mold's inner surface and the part continues to form until all of the resin is completely fused. The mold is then cooled by air or water or both until the mold returns to standard temperature. The mold is then opened and the part is removed.
A variety of materials are available for rotomolding, however, the most commonly used material is Polyethylene. Plastisols, polypropylene, nylons and fluoropolymers can also be rotomolded. Additive packages are also available, which allow added flexibility in part functionality; UV stabilizers, cross-links, non-static conducting packages. The benefits of rotational molding are many. Parts can be molded in a variety of shapes and sizes, many of them impossible to produce in any other process. Tooling costs are usually lower than any other process due to the fact that there is no pressure involved. Many molds can be thin walled aluminum castings or sheet metal fabrication. Mold turn around is shorter than most other molding processes. Rotomolded parts have excellent load-bearing properties and have a greater resistance to cracking and corrosion due to a "stress free" molding environment.

Remcon Plastics has been rotomolding quality parts since 1982. We offer a complete line of proprietary products for a variety of industries as well as custom molding for OEM customers. Our plant is approximately 78,000 square feet and is equipped with six rotomolding machines.
Our Ferry RS-400 is one of the largest rotomolding machines on the east coast. The machine has 160" swing capabilities and each straight arm is rated for a 5,000 pound capacity (Combined weight of mold and material). Which means that we can mold a part as large as a 4,000-gallon tank (Approx. 125" diameter by 80" tall). We also have two Ferry RS-220 machines, two Ferry RS-280 machines and one Akron Crane 95.)
Our plant is equipped with Rotolog, which monitors the temperature of the part during the production cycle and helps insure the parts quality. If your part requires secondary operations, we also have a 5 axis CNC routing machine to insure consistency of each part. We provide finishing, stenciling, molded in graphics, assembly, packaging and many other valuable services. Engineering and Design services are also available from our in-house engineering staff to ensure your part design is the best it can be.
Rapid Prototyping - Remcon also has the capability to create "prototype tools" capable of making 5 to 10 parts in a matter of weeks.
