Rotational Molding (Rotomolding)

Rotational Molding (often called rotomolding) is a process of making hollow plastic parts by rotating melted plastics along 2 axes inside a hot mold. The hot mold is cooled while it continues rotating to create an even coating of plastic along the inside of the mold walls.

Our philosophy is to partner with our customers whenever we can because when our customers do well we will too. This partnering takes many forms. We like to be involved early in projects so we can help design for the highest quality at the lowest price. We will run warehouses for our customers shipping directly to their customers to minimize freight and handling cost. We focus on how we can do better as a team.

Lean manufacturing

Everyone says they have lean manufacturing but Trilogy lives it and has for years. Our 6S and continuous improvement process delivers the highest quality and a flexible process. That's how we can achieve 99% plus on-time delivery every year while responding to fluctuating demands.

Flexible attitude

We want to do what makes sense for both the customer and Trilogy so we keep an open mind. If we have to develop a new process or run a new material that has never been done before we are willing to try. We have used robots to solve particularly difficult decorating problems and developed a new process to solve foam adhesion. We don't limit ourselves to what we have done but always look at what we can do.

Dedicated employees

We are located in a small Ohio town where people still care about doing a good job and take pride in their work. Trilogy works hard to find, train and keep the best people because they deliver for our customers.
