With the current competitive environment in the manufacturing industry, it is important to identify an effective precision overmolding manufacturer that can deliver high-quality products, high durability, and ergonomics in products. We are the experts in offering precision overmolding solutions to a broad spectrum of industries at SunOn, such as electronics, automobiles, medical equipment, and consumer products. Our experience will make every overmolded part of high quality and the most functional and appealing to the eye.
What is Precision Overmolding?
Precision overmolding can be defined as the sophisticated manufacturing technique in which two or more materials are embedded in one component through the application of the thermoplastic overmolding procedures. This may involve TPU and silicone overmolding, soft-touch, and multi-material compounds to make the products more durable, ergonomic, and aesthetic. Precision overmolding, in contrast to conventional assembly, who use adhesives or fasteners, does not require labor because it removes the use of adhesives or fasteners.
Important Benefits of Collaborating with a Precision Overmolding
Collaborating with a manufacturer of expertise in precision overmolding, such as SunOn, would have various benefits:
Increased Product Life: Overmolded parts have excellent wear, impact, and environmental resistance.
Ergonomic Design: Perfect to use in tool grips, tool handles, and consumer electronics where comfort to the user is needed.
Cost-Efficiency: It minimizes assembly operations and manpower needs and enhances cycle time.
Multi-Material Solutions: Allows soft-touch and hard cores, as well as specialty plastics, to be incorporated in a single part.
Quality Finishes: This is done through precision mold fabrication, which means that there are no rough borders, transitions are seamless, and it has a pleasing look.

Precision Overmolding Process: The Working Principle
SunOn uses the latest methods in high-precision overmolding:
Mold Cavity Design: Advanced mold cavity design of precision overmolding guarantees the consistency and perfection in the overmolding.
Material Choice: TPU, silicone, Thermoplastic elastomers, and reinforced polymers are selected according to their performance requirements.
Injection Overmolding: Multi-shot overmolding is our technique that combines several materials at once in one cycle in order to achieve uniform quality.
Robotic & Automated Systems: Automation enhances the efficiency of the cycle time and reduces the effect of human error.
Post-Processing and Inspection: Each batch is checked in terms of shrink compensation, surface finish quality, and the strength of bonding between the materials.
Through the use of overmolding and insert molding, we can produce parts with metal or plastic inserts that are embedded to enhance their strength and functionality.
Precision Overmolding Materials
A manufacturer of precision overmolding needs to be skilled in a large variety of materials:
TPU Overmolding: Soft-feeling, flexible, wearable devices, grips, and other wearable devices.
Silicone Overmolding: A heat-stable and chemically stable compound with medical or consumer usage.
