Anti-slip, Shockproof, Sealing & Wear-resistant, Cost-effective Solution
Overview：We offer professional overmolding solutions that combine rigid engineering plastics with soft TPE/TPU or secondary hard materials in one integrated process. It creates parts with enhanced grip, impact resistance, and ergonomic comfort, eliminating assembly steps and improving product durability. We support design optimization, mold customization, prototyping, and mass production for consumer electronics, automotive, and household applications.
Overmolding is a mature secondary injection molding technology. The rigid base part is molded first, then soft materials are injected to fully cover its surface. It achieves seamless fusion under high temperature without adhesive bonding, greatly improving product grip, protection performance and layered appearance for functional plastic products.
Soft-to-Hard Overmolding: Encapsulate rigid plastic or metal parts with TPE/TPU for grip, comfort, and sealing
Hard-to-Hard Overmolding: Combine two different rigid materials for multi-color or multi-functional parts
Ergonomic & Functional Design: Custom textures and shapes to improve user experience and product performance
Insert Integration: Combine overmolding with metal inserts to add strength and conductivity in one process
Prototype & Volume Production: From quick samples to high-volume manufacturing with consistent quality control
Two Shot Overmolding
It combines the advantages of two-color injection and overmolding technology. It realizes dual-color design and hard-soft wrapping forming at one time, with accurate positioning and neat color boundary. Perfect for mass production of high-grade appearance products.
Silicone Overmolding
Adopt silicone as outer wrapping material, featuring food safety grade, high temperature resistance, waterproof sealing, skin-friendly and anti-slip performance. Eco-friendly, non-toxic and anti-aging, widely used in baby products, kitchenware, medical devices and daily necessities.
Rubber Overmolding
Soft rubber overmolding owns strong elasticity, excellent shock absorption, great wear resistance and tear resistance. It is suitable for heavy-duty scenarios such as industrial tools, outdoor equipment and heavy grip accessories.
Plastic Overmolding
Adopt soft engineering plastic such as TPE and TPU for outer wrapping. It has high cost performance, rich color options and moderate flexibility, easy for mass production, which is the most common solution for consumer electronics and home appliance parts.
Overmolding Silicone
Including common anti-slip silicone, food-grade silicone, medical-grade silicone, high-temperature resistant silicone and flame-retardant silicone. Soft, breathable, with excellent sealing, heat insulation and drop resistance, hardness and color can be customized.
Composite Overmolding Process
Multi-material layered composite wrapping process, supporting partial fixed-point overmolding and full coverage overmolding. It can realize anti-slip, sealing, heat insulation and insulation functions at the same time with highly flexible structural design.
Overmolding Plastic
Common rigid base plastic: ABS, PP, PC, PA66, POM, HIPS, PE. Features high hardness, stable structure, precise dimension and strong supporting force, used as internal framework to match all kinds of soft wrapping materials.
Low Pressure Overmolding
Low pressure and low speed injection molding with mild injection pressure, which will not damage tiny precision base parts. It effectively reduces internal stress and avoids deformation, cracking and whitening, ideal for thin-wall parts and fragile component overmolding.

Optimized material pairing and surface preparation ensure reliable adhesion between layers, preventing delamination
Precision molds with advanced runner and venting systems to handle two-shot molding challenges
Deep experience in matching rigid and soft materials to meet mechanical, thermal, and tactile requirements
Strict quality checks at every stage to ensure dimensional accuracy and consistent part quality
Eliminates secondary assembly steps and improves product reliability
From DFM analysis and mold making to prototyping and mass production, with dedicated project management
We adopt compatible matched materials and standard molding process to avoid peeling, delamination and cracking in long-term use.
Low pressure overmolding is most suitable for thin-wall parts, tiny structural parts and easy-deformation fragile plastic products.
Silicone can be perfectly combined with PP, ABS, PC and other plastics for stable and safe overmolding production.
Two shot overmolding owns higher precision and better integrated appearance for high-end products, while ordinary overmolding is more cost-effective for common functional goods.
