What Our Customers Say About Plastic Molding Services from Springboard

"We reached out to Springboard to help us create some plastic part and components to fit our medical devices. They were able to make it as both subassemblies as well as other components for our more complex medical devices…We were very pleased with our experience with stacks as they kept us informed throughout the entire process and allowed us to make changes to our parts even after the production process began."

Additional Plastic Molding Services

Plastic injection molding and other custom plastic molding services are designed to effectively mass-produce plastic parts and/or products in a short amount of time. Plastic molding services allows thousands or even millions of high quality, high precision parts to be manufactured with perfect repeatability and with relatively quick turnaround times. At Stack Plastics, we offer the following plastic molding services:

  • Overmolding Overmolding is a standard plastic injection process that combines a base layer mold with additional plastic layers that are molded around the part. Overmolding improves product grip and ergonomics, allow for electrical insulation, or create a waterproof seal.
  • Insert Molding Insert molding allows for a previously fabricated component to be fully encapsulated in a molten resin to create a finished part. Plastic insert molding is ideal for improving the strength and reliability of a component and can help save on cost and production time.
  • Ultrasonic Bonding The ultrasonic bonding process utilizes high frequency sound waves to fuse together two separate workpieces. Sonic welding decreases production costs while producing high quality bonds with tight seals.
  • Micro Molding Micro injection molding is highly useful in the medical and electronic industries and produces high precision parts that are extremely small, weighing in at less than one gram. Stack Plastics has the capabilities to produce miniscule parts with intricate details and features that would be impossible to manufacture by other means.
