Rotational Molding Capabilities
Rotational molding (rotomolding) is a process where powdered plastic is placed into a hollow mold that is heated and slowly rotated along two perpendicular axes. The plastic melts and coats the inside of the mold uniformly. After cooling, the seamless hollow part is removed. Rotomolding excels at producing large hollow parts with uniform wall thickness and no seams or weld lines. It is ideal for low-to-medium volume production because tooling costs are significantly lower than injection molding or blow molding. Common products include water tanks, septic tanks, playground equipment, kayaks, coolers, and furniture.

Rotational Molding in Elkhart — FAQ
How many Rotational Molding providers are in Elkhart, IN?
The Elkhart-Goshen metropolitan area has approximately 900 manufacturing establishments, many of which offer rotational molding services. The area employs about 42,000 manufacturing workers, ensuring a skilled workforce for your project.
What size parts can rotational molding produce?
Rotational molding can produce parts from small housings (a few inches) to very large tanks and containers up to 20+ feet in length and thousands of gallons in capacity. It's one of the best processes for very large hollow parts.
Why choose rotomolding over blow molding?
Rotomolding has lower tooling costs (aluminum vs. steel molds), produces more uniform wall thickness, handles larger parts, and is more economical at lower volumes. Blow molding is faster and better for very high volumes of smaller parts like bottles.
What is the minimum order for rotational molding?
Rotomolding is economical even at quantities as low as 25-100 parts because of its low tooling cost. Some shops will produce single prototype parts. This makes it ideal for niche products and low-volume production.
How strong are rotomolded parts?
Rotomolded parts are seamless and have uniform wall thickness, resulting in excellent impact resistance and stress distribution. They are highly durable and resist cracking, making them ideal for tanks, containers, and outdoor equipment.
