Low pressure overmolding is a great option for packaging electronics in the medium to high volume range. Injection and demolding times are very short with little labor involved. One-shot overmolding is optimal to keep costs down but multiple-shots can be performed for large products or multiple colors.
Thermoset materials like Polyurethane & Epoxy can be used for overmolding sensitive components and materials. Generally these materials are used for casting, potting and encapsulation but we can also inject these materials into closed into closed cavities.
With this injection process we can mold plastic and rubber directly onto pc boards, batteries, LEDs and antennas. The best part about this process is it can be performed at 90 degrees Fahrenheit and as low as 5 PSI — unlike any other injection molding process.
Ramp up and transfer is a service we offer to customer that know in the end that they want to perform the overmolding at their location but don’t have the capacity or capability to make the tooling, resaerch the correct equipment, choose the correct molding compound or develop a process and then validate it.
With our in-house tooling department, extensive overmolding experience and unbiased expertise, we can help you through the steps or we can take ownership of the entire process. We start by choosing the correct equipment for your project, then we manufacture the tooling, next we set up and run first articles units for approval and finally we create production quantities. When your manufacturing area is ready, this entire process can be transferred to your facility for continued production.
Building a prototype is a major part of the process required for main line production. With the prototype you can determine any modifications that will need to be made before tooling and machines can be setup for production. We can fabricate a single cavity prototype mold for overmolding your electronic assembly. With this mold you will have the capability of producing enough parts to perform all your pre-production testing. The prototype mold will also allow you to test various molding materials.
