From the manufacturing of individual components to fully-assembled functional devices, play the ultimate game of mix n' match with GMN Plastics! We understand that bundling parts and working with one instead of several suppliers saves you both time and money. That’s why GMN Plastics takes the holistic approach to building products by offering an incredibly diverse range of capabilities through its parent company, GM Nameplate.
Whether you are looking for labels, graphic overlays, die-cut components, or backlighting options, you’ll get custom-engineered solutions to fit your every need, big and small. With faster time to market and increased quality control, our electro-mechanical assemblies will provide you with a more reliable and streamlined supply chain. To create a winning solution, explore our vertically-integrated capabilities here.
In addition to our molding capabilities, GMN Plastics has consistently added complementary processes and services to meet the evolving needs of our customers. With a dedicated machining area and equipment, GMN Plastics offers secondary machining of injection molded parts. Some of the core benefits include modifying an existing part, de-gating, taping holes, or simply fine trimming a critical component. This secondary process can also help to reduce costs related to tooling by providing the flexibility to make design modifications before investing in a tool. As the majority of the components manufactured at GMN Plastics are employed in critical environments like surgical rooms and airplanes, our machining capability allows us to engineer parts that conform to the highest quality standards.
Plastic housing insert options
At GMN Plastics, we manufacture a multitude of plastic housings each day. As most housings require further assembly and need to be joined together, we offer different ways to add inserts to your parts.
Brass inserts are inserted onto a pin inside the molding machine. Once the plastic is injected into the mold, it surrounds the insert and molds it in place. By eliminating a secondary operation, this method is time and cost effective. For applications where it is unfeasible to mold-in the insert, a different approach like ultrasonic welding or heat staking is utilized.
Ultrasonic welding uses high-frequency acoustic vibrations to install an insert into a plastic component. The friction created between the insert and the plastic surface causes the plastic around the insert to melt. The insert is swiftly embedded in the correct location, creating a robust bond once the melted plastic cools and solidifies. Commonly used for joining dissimilar materials, this industrial process is extremely precise and requires seconds to complete.
Heat staking, also known as thermal insertion, uses a probe that is heated above the melting point of the plastic. The probe is applied to the insert, thereby transferring the heat and melting the plastic around the insert. The insert is pressured down to the desired spot before the plastic cools down. Ideal for multi-insert designs, heat staking is a great choice for complex geometries requiring inserts on different levels.
