Medical Device Overmolding | Custom Two-Shot Solutions
What is Medical Device Overmolding?
- Medical device overmolding is a complicated fabrication technique that involves the integration of two or more materials into one cohesive unit. This process is frequently done in two-shot molding of medical devices, bi-material injection molding of medical components, it can be used to create soft-touch finishes, ergonomic grips, two-color finishes, and high-function assemblies.
- Overmolding, as compared to the traditional molding process, not only removes the process of assembling, but it also lowers the manufacturing cost of labor and increases the performance, biocompatibility, and aesthetic of the medical equipment. The integration of such materials as thermoplastics, silicones, and TPEs allows the manufacturers to design the components that may be handled, withstand sterilization, and meet all healthcare requirements.

Medical Device Overmolding Uses
The application of medical device overmolding is found in a broad range of medical practices, which offers durability, comfort, and functionality:
Surgical Instruments
- Surgical tools are two-shot overmolded to provide ergonomic handles, a non-slip surface, and biocompatible materials.
- Overmolding solutions (with multi-materials) enhance sterility and durability.
Diagnostic Equipment
- Overmolding of diagnostic equipment promotes more accuracy, comfort ability and usefulness.
- Bi-material over-molding medical components offer solutions that offer functionality and tactile response to delicate tools.
Healthcare Devices
- Overmolding with the soft-touch of medical equipment enhances the comfort of prolonged procedures for users.
Such components as thermoplastic overmolding medical parts and dual-material injection molding medical parts enhance durability and chemical resistance.

The medical two-shot technique offers SunOn the chance to create complex geometry molded products, such as over-molded ergonomic handles on medical instruments, diagnostic equipment enclosures, and soft-touch healthcare products.

Overmolding Media in Medical Devices
The choice of the material used is very important to medical applications because it influences biocompatibility, durability, and sterilization. SunOn deals with a large variety of medical-grade materials:
- Thermoplastics: ABS, PC, PP, and PE of structural parts.
- Silicone and TPE: To soften hand ergonomics.
- Bio-Compatible Polymers: Adherent to FDA and ISO standards.
The compatibility of resin, control of the temperature of the mold, and the dynamics of polymer flow should be optimized to ensure that the process of medical molding is exact with a perfect finish and a high quality of performance.
