Not Sure Which Material Combination Works Best?
Send us your drawing or sample details. TryCooler can help review material fit, bonding risk and molding feasibility before tooling.
Our Overmolding Options
At TryCooler, we support different overmolding solutions to combine materials, improve product performance, and create durable multi-material parts for your application.
Combine two plastic materials or colors into one molded part to improve structure, appearance, and product functionality while reducing secondary assembly.
Mold TPE, TPU, silicone, or rubber-like materials over rigid plastic substrates to improve grip, comfort, sealing, and impact protection.
Encapsulate metal inserts, threaded studs, bushings, or cores with plastic to improve strength, insulation, and part integration.
Bond flexible elastomers or silicone materials to metal substrates for vibration damping, sealing, protection, and long-term durability.

From drawing review to production delivery.
Plastic, TPE, TPU, silicone, LSR and metal insert overmolding.
Tooling, samples and production managed together.
ISO 9001:2015 process for consistent batch quality.
Material Pairing for Reliable Overmolded Parts
Not every soft material bonds reliably with rigid substrates.
TryCooler reviews material fit, bonding design, and molding feasibility before tooling to reduce peeling, poor adhesion, and production risks.
- Common Overmolding Material Combinations
| Substrate | Overmold Material | Suitable Applications | Key Review Point |
| ABS / PC / PC ABS | TPE / TPU | Handles, electronic housings, consumer products, tool grips | Bonding performance, soft-touch feel, appearance, shrinkage |
| PP | Special TPE / TPV / TPO | Household products, daily-use parts, containers, plastic housings | PP has lower surface energy; special material grades or mechanical interlock may be required |
| PA / Nylon | TPE / TPU | Tools, automotive parts, industrial components, wear-resistant parts | Material drying, shrinkage difference, wear resistance, bonding structure |
| Metal Inserts | Plastic / TPE / TPU / Silicone | Connectors, threaded inserts, bushings, hardware parts, structural components | Encapsulation design, undercuts, grooves, mechanical locking |
| Rigid Plastic or Metal | Silicone / LSR | Sealing parts, waterproof parts, healthcare devices, wearable products, protective parts | Surface condition, sealing structure, bonding risk, use environment |
Our Overmolding Process
A clear workflow from design review to production-ready overmolded parts.
We review your drawings, material requirements, bonding areas and tooling feasibility before mold making.
We recommend suitable plastic, TPE, TPU, silicone or insert overmolding solutions based on your application.
T1 samples are provided for dimension, appearance, bonding and functional verification.
We support prototype validation, small batch trials and stable OEM mass production.
Finished parts are checked for dimensions, bonding, appearance, assembly fit and packaging before shipment.
Common materials include ABS, PC, PP, PA, TPE, TPU, silicone, LSR, and metal inserts. The final material choice depends on bonding, hardness, product function, and application environment.
Yes. TryCooler can review your 3D files, material requirements, bonding areas, overmold thickness, and tooling feasibility before mold making.
We review material compatibility, bonding structure, mechanical interlock, overmolded edges, and molding feasibility before tooling to help reduce peeling and weak adhesion risks.
STEP or STP 3D files are preferred. We can also review 2D drawings, samples, product photos, material requirements, estimated quantity, and application details.
Yes. We support prototype samples, small batch trials, and OEM mass production based on your product structure and tooling requirements.
Our ISO 9001:2015 certified process helps ensure consistent quality in every production batch. We check material, bonding, dimensions, appearance, hardness, assembly fit, packaging, and final shipment requirements.
Yes. Your drawings, samples, and project information can be kept secure and confidential. NNN or NDA support is available for custom OEM and ODM projects.
Overmolding cost is mainly affected by material choice, mold complexity, part size, tolerance, bonding requirements, order quantity, surface finish, and secondary operations. TryCooler reviews your drawings and application needs to recommend a cost-effective and stable production solution.
