What is Overmolding?
Overmolding is a process where a secondary material like rubber or plastic is injected over a base part, enhancing grip, ergonomics, and durability. Common applications include overmolded handles and overmolded plastic components. Rubber overmolding adds comfort, while plastic overmolding provides strength. This technique is also used in electronics overmolding to protect sensitive components. Our overmolding services offer customizable solutions for both low-volume and high-volume production. With a range of materials and advanced techniques, we ensure high-quality, cost-effective results tailored to your specific needs.

FAQs of Overmolding Process
What is the difference between overmolding and insert molding?
Overmolding: A secondary material (like rubber) is molded over a base part, giving it a soft feel, better grip, and added durability.
Insert Molding: A pre-made part (usually metal) is placed in a mold, and plastic is injected around it, creating a strong bond for added strength and functionality. Looking for custom overmolding solutions? Contact us!
