オーバーモールディング

In product design, performance matters—but so does how it feels in the hand, how it grips, insulates, or protects. That’s where overmolding changes the game. At エリート・モールド・テック, we help brands enhance both function and aesthetics by seamlessly combining multiple materials into a single part—without screws, adhesives, or assembly lines.

From soft-touch handles to vibration-dampening housings, overmolding adds value where it counts.

What Is Overmolding?

Overmolding is a two-step injection molding process where one material (typically a soft thermoplastic elastomer or TPE) is molded over another (often a rigid plastic or metal substrate). The result is a cohesive, multi-material component with enhanced function and user experience.

This technique enables integration of soft grips, seals, or insulation directly onto structural components, eliminating the need for secondary operations.

Elite Mold Tech uses overmolding to help clients create durable, ergonomic, and visually appealing parts with reduced complexity.

Where Performance Meets Design

Overmolding is not just about looks—it provides real mechanical and chemical benefits. Here’s what it can offer your product:

• Improved ergonomics with non-slip surfaces

• Shock and vibration absorption

• Sealing against moisture, dust, and chemicals

• Electrical insulation and wire strain relief

• Tamper-proof or child-safe features

• Brand differentiation through color and texture contrast

Whether you’re building consumer goods, medical devices, or rugged industrial tools, overmolding adds tactile and technical value.

Our Overmolding Capabilities

Elite Mold Tech is equipped with the expertise and technology to handle single-shot and multi-shot overmolding with precision. We specialize in:

• Overmolding soft materials (TPE, TPU, silicone) over hard plastics (ABS, PC, nylon)

• Bonding over metal inserts or electronics

• Color, texture, and hardness customization

• Tooling for tight material compatibility tolerances

• Cleanroom-capable molding for medical and pharma sectors

We also offer early-stage design feedback to ensure your overmolded parts are both functional and manufacturable.

Typical Applications of Overmolding

Overmolding is used in nearly every sector where durability and design meet. Examples include:

• メディカル – Grips on surgical tools, blood collection handles, soft closures

• Consumer Products – Razor handles, toothbrushes, kitchen tools

• Industrial & Power Tools – Vibration-dampening grips, trigger covers

• Electronics – Wire seals, USB connectors, device enclosures

• 自動車 – Shift knobs, pedal pads, climate control buttons

Elite Mold Tech tailors each overmolding project to your product’s purpose and your industry’s demands.

Quality You Can Feel

The challenge in overmolding lies in achieving a perfect bond between materials with different properties. Our team uses advanced material selection, precision tooling, and mold flow analysis to ensure adhesion, longevity, and flawless appearance.

With in-house toolmaking and material testing, we minimize cycle times while maximizing product integrity.

We also ensure repeatability, even in multi-cavity, high-volume runs—so every unit delivers the same performance and finish.
