If you work in rotomolding, you've experienced it: the raw material hasn't changed, the mold hasn't changed, yet problems keep cropping up in your products. Bubbles on the surface, voids inside, warpage and distortion after cooling, uneven wall thickness — scrap rates remain stubbornly high.

Summer Maintenance Guide for Rotomolding machines' Electrical Cabinets

In our last installment, we explored the fundamental principles behind rotational molding — no high pressure, almost zero waste, just a simple and efficient process that has established itself firmly in the world of hollow plastic products. If the science we covered is the skeleton of rotomolding, then what we’re diving into today — its application areas — is the lifeblood that keeps it moving.

From large outdoor water tanks and septic tanks to small playground equipment and agricultural parts, many hollow plastic products owe their existence to an unsung yet highly effective technology — rotational molding (commonly called rotomolding).
