Overmolding & Insert Molding Services – Complex Custom Components

Custom Injection Molded Parts with Overmolding: Enhancing Grip and Functionality
We specialize in creating custom injection molded parts using overmolding, a technique that bonds two or more materials into a single component, enhancing both functionality and user experience. This process is ideal for parts needing a soft, grippy surface combined with a rigid core—think tool handles, medical device grips, and consumer product controls. We often pair hard plastics like ABS or PC with soft thermoplastic elastomers (TPE) or rubber, ensuring a secure bond that withstands repeated use and cleaning. Our overmolding expertise allows us to design complex geometries, integrating features like ergonomic contours or sealing gaskets in one step, reducing assembly time and costs. Whether it’s a surgical instrument handle requiring a non-slip grip or a power tool needing vibration dampening, our custom injection molded parts with overmolding deliver durability, comfort, and precision, meeting the unique demands of each application.

Custom Injection Molded Parts with Insert Molding: Combining Strength and Versatility
Insert molding is our go-to method for producing custom injection molded parts that integrate metal or other materials into plastic components, creating strong, multi-material assemblies. We insert metal threads, pins, or mesh into molds before injecting plastic, resulting in parts like electrical connectors with embedded terminals, automotive brackets with reinforced metal inserts, or industrial fasteners with durable plastic bodies. This process eliminates the need for secondary assembly steps, reducing the risk of loose components and improving overall part strength. We work with a range of insert materials, including stainless steel, brass, and even ceramics, ensuring compatibility with the base plastic—whether it’s nylon, POM, or high-temperature resins. Our precision tooling ensures inserts are perfectly positioned, maintaining tight tolerances critical for applications like aerospace components or medical device hardware, where reliability is non-negotiable.

Custom Injection Molded Parts for Medical Devices: Sterility and Comfort
In medical device manufacturing, custom injection molded parts made with overmolding and insert molding must meet strict standards for sterility, biocompatibility, and user comfort—and we deliver on all fronts. Overmolding allows us to create components like catheter handles with soft, latex-free grips that remain comfortable during long procedures, while insert molding integrates metal sensors or electrical contacts into plastic housings for diagnostic equipment, ensuring reliable performance. We use medical-grade materials such as USP Class VI TPE and biocompatible PC, paired with stainless steel inserts, to meet FDA and ISO requirements. Our cleanroom processes prevent contamination, and our designs prioritize easy sterilization, with smooth surfaces that resist bacteria buildup. From surgical tools to patient monitors, our custom injection molded parts for medical devices combine functionality with the safety and comfort needed in healthcare settings.

Custom Injection Molded Parts for Electronics: Sealing and Conductivity
Electronics demand custom injection molded parts that protect sensitive components from moisture, dust, and impact—tasks overmolding and insert molding handle exceptionally well. Overmolding creates watertight seals for devices like smartphones and wearables, using TPE to seal gaps around ports and buttons, while the rigid plastic core provides structural support. Insert molding integrates conductive metal inserts into plastic casings for connectors and circuit boards, ensuring reliable electrical conductivity without the need for soldering. We select materials like flame-retardant ABS and high-insulation PBT to meet safety standards, and our precision molding ensures inserts align perfectly with circuit pathways. Whether it’s a rugged tablet case for industrial use or a compact sensor housing for smart home devices, our custom injection molded parts for electronics offer the durability and performance needed to protect delicate technology.

Custom Injection Molded Parts for Automotive: Durability and Integration
The automotive industry relies on custom injection molded parts made with overmolding and insert molding to withstand harsh conditions while integrating multiple functions. Overmolding creates weather-resistant seals for door handles and window controls, pairing rigid nylon with UV-stable TPE to resist fading and cracking. Insert molding embeds metal bolts or brackets into plastic components like engine mounts and interior trim, reducing weight while maintaining strength. We use heat-resistant materials such as PA66 and PEEK for under-the-hood parts, ensuring they stand up to high temperatures and chemical exposure. Our ability to combine materials in a single process streamlines production, lowering costs for automotive clients. From electric vehicle battery components to traditional car interior parts, our custom injection molded parts for automotive applications deliver the durability, integration, and performance needed for the road.

Custom Injection Molded Parts for Industrial Equipment: Heavy-Duty Performance
Industrial equipment requires custom injection molded parts that can handle heavy loads, frequent use, and harsh environments—and overmolding and insert molding make that possible. Overmolding creates shock-absorbing components like conveyor belt rollers, using tough TPE over a rigid plastic core to reduce noise and wear. Insert molding reinforces industrial handles and levers with metal inserts, ensuring they can withstand repeated force without breaking. We use robust materials such as glass-filled nylon and impact-resistant POM, paired with corrosion-resistant metal inserts, to create parts that resist chemicals, temperature extremes, and abrasion. Our designs focus on longevity, reducing the need for frequent replacements in factories, construction sites, and mining operations. Whether it’s a heavy machinery control panel or a material handling component, our custom injection molded parts for industrial equipment deliver the heavy-duty performance and reliability that industrial clients depend on.
