Custom Rotational Molding Molds, Made From Your Part — Not From a Catalog
Most buyers who come to us do not start with a mold. They start with a part: a fuel tank that leaks at the seam, a case that cracks at the corner, a housing that costs too much to machine. They bring us the part itself, or a 3D file, and ask one question — can you make this, and what will it take?
That is the whole job. We make the mold, we run the parts, and the mold stays yours. This page explains exactly how that works, what it costs, and how long it takes — with nothing left vague, because a mold is the one place where vague gets expensive.

A word on the mold fee, because this is where buyers get burned. Some suppliers keep the mold, or charge you again when you reorder. We do not. You pay for the mold once, it is yours, and your design stays your design.
If your orders build up to 10,000 pieces or more, we refund the fee — and we put that in writing before we start.
