At Great Lakes Trim Inc., we are dedicated to giving our customers the best possible solutions. With our extensive range of equipment, no job is too challenging. We stay ahead of the curve by continually improving upon existing systems for maximum efficiency.  


Robotic Trimming

Using advanced software and precision cutting tools, we can trim complex shapes and curves with unparalleled accuracy and speed, resulting in consistent and precise parts. Robotic trimming also allows us to produce higher-quality trim parts at a faster rate, improving overall productivity and reducing lead times.

Compression Molding

Preheated material is placed into a heated mold cavity and compressed under high pressure until it takes on the desired shape. Ideal for producing complex parts with intricate designs and varying thicknesses, it offers excellent dimensional stability, consistency, and repeatability. The process helps produce products resistant to heat, moisture, and abrasion.

Sonic Welding

High-frequency vibrations melt and fuse the plastic pieces, creating a strong and seamless bond. Sonic welding is particularly useful for trim parts such as door panels, dashboards, and interior consoles, as it allows for precise and efficient assembly. Additionally, it produces minimal waste and is environmentally friendly. 

Thermal Forming

Used to help shape plastic sheets into various forms and designs, this process involves heating a plastic sheet to a temperature where it can be easily manipulated, and then applying pressure to create the desired shape. It offers numerous benefits, including lower tooling costs, faster production times, and the ability to create complex shapes and designs.

In-Mold Grain (IMG) Thermoforming

A textured finish is applied to the surface of the component during the molding process using a combination of heat and pressure to mold plastic into desired shape and texture while embossing a decorative grain pattern onto the surface. The result is a high-quality, durable trim part that is not only resistant to wear and tear but has a premium look.

CNC Cutting

This machine uses computer-aided design (CAD) software to precisely cut and shape materials such as plastic, aluminum, and steel into the desired shapes and sizes. This allows for the creation of intricate designs and patterns that would be difficult to achieve using traditional cutting methods. It also ensures a high level of accuracy and consistency, reducing waste and increasing efficiency in the production process.

Spray Transfer Molding (STM)

Spray Transfer Molding (STM)  involves spraying a mixture of resin and chopped fibers onto a mold surface, followed by compaction using a transfer pad. The resulting part has an excellent surface finish and mechanical properties, making it ideal for use in high-end automotive applications. STM is a cost-effective alternative to traditional injection molding, as it requires less tooling and has a shorter cycle time. At the same time, it offers greater design flexibility and the ability to produce complex shapes and contours with ease.

Structural Reaction Injection Molding (RIM)

With Structural RIM (Reaction Injection Molding) the injection of thermosetting polymers into a closed mold creates a durable, high-strength composite material. Structural RIM allows us to produce large, complex parts with excellent dimensional stability and consistent wall thickness. Structural RIM parts are lightweight and have a high strength-to-weight ratio, making them ideal for use in automotive applications where weight reduction is a priority.
