Overmolding Injection Molding Service TPE Soft Touch Grip Two Shot Molding

Overmolding bonds a soft TPE or TPU skin to a rigid substrate in one two shot process, producing grips and seals that feel good and stay attached. This service covers two shot rotary molds and insert overmolding for tools, electronics, and appliances.

We engineer substrate design, bonding chemistry, and gate placement so that the soft layer adheres firmly and survives repeated flexing and cleaning.

• Two shot in one cycle: rigid plus soft layers bonded without manual assembly
• Durable TPE bonding: mechanical and chemical adhesion that resists peeling
• Soft touch feel: textured grips with the hardness you specify
• Sealing capability: overmolded gaskets for water and dust resistance
• Multi material options: TPE, TPU, and silicone overmold combinations
• Consistent quality: process control on both shots for stable output

Two shot overmolding removes a costly assembly step and improves the feel and durability of a product in one operation.

• Substrate and overmold design review to guarantee a strong mechanical lock
• Material pairing selection for reliable chemical bonding
• Rotary table or core back tooling matched to your press and volume
• Seal and gasket overmolding for IP rated enclosures

• Power tool and hand tool grips
• Electronics and wearable soft touch housings
• Appliance handles and control knobs
• Automotive knobs, seals, and trims
• Sports, medical, and personal care grips

With more than 18 years of focused experience in plastic injection molding, our factory runs an integrated tooling room, a clean injection workshop, and a controlled assembly line under one roof. We are ISO 9001:2015 certified and export precision molds and molded components to over 40 countries across Europe, North America, and Southeast Asia, supporting OEM and ODM programs from concept to serial delivery.

• 18 years of OEM and ODM experience in plastic injection molding with an integrated tooling room and clean injection workshop
• Injection machines from 60T to 1600T, all fitted with controlled robotic handling systems
• Advanced equipment and skilled engineers covering CNC machining, EDM, wire cutting, mold flow analysis, and DFM reporting
• In-house prototyping, tooling, injection, painting, printing, and assembly services delivered under one roof
• Experienced quality team performing dimensional inspection with CMM and 3D scanning before every shipment

Typical lead times are shown above. Provide your design and volume and we will confirm the tooling concept and schedule in the DFM quotation.

• A tool brand replaced a glued rubber grip with a two shot TPE overmold and removed a manual assembly station.
• An electronics OEM used overmolded sealing to reach an IP54 rating without adding a separate gasket.
• An appliance maker improved grip comfort while cutting part count by combining two parts into one overmolded piece.

Molds ship in a treated wooden case with anti-rust film, a mold report, and process notes for both shots. Molded parts are packed in PE bags inside cartons, or in returnable trays for high volume programs.

Q1. Can you make a prototype for us?

Yes. We produce prototypes by CNC machining and hand polishing so that fit, finish, and function can be validated before tooling is cut.

Q2. How can I place an order?

Send your 2D and 3D drawings (a .step file is preferred) together with annual volume, material, and surface requirements. Our engineers reply with a DFM report and quotation within one working day.

Q3. How can I get a sample to check your quality?

After price confirmation you can request samples. For a new mold we provide T1 samples for evaluation; the buyer covers the express freight.

Q4. Can you do the design for us?

Yes. Our design team has rich experience in plastic products and molds. Share your idea or a reference part and we will refine it into a manufacturable design.

Q5. How long can I expect to get the sample and mass production?

For an existing mold, samples take 3-7 days and mass production 1-2 weeks. For a new mold, allow 25-35 days for mold building plus 1-4 weeks for mass production.

Q6. What are your terms of delivery?

We accept EXW, FOB, CFR, CIF, DDU, and DDP. Choose the option that best fits your cost and logistics plan.
