Overmolding & Insert Molding
Combine rigid structures with soft surfaces or integrate a preformed insert into a molded part. Explore functional, tactile and assembly requirements together.
Built around your requirements
OPINOX describes overmolding with elastomer materials such as TPE, TPR and TPU, and insert molding around preformed components. Material compatibility, adhesion, geometry and the production sequence are evaluated for the specific part.

Start with a clear brief
Send the drawing or sample reference, estimated quantity, material preferences, critical tolerances and appearance requirements. Delivery and acceptance terms will be reviewed for your project.
Before you request a quotation
What information should I prepare?
Share drawings or a sample reference, the intended application, estimated order quantity, material preferences and critical dimensions. Tell us about appearance, assembly and packaging requirements.
How are samples and production approved?
Agree on the tooling proposal and sample requirements for the project. Trial samples are reviewed before the agreed production plan proceeds. Confirm the acceptance criteria with the project team.
What determines price and lead time?
Part geometry, material, tooling construction, appearance requirements and quantity affect the project plan. Price, minimum order quantity and delivery are reviewed for each enquiry.
Define the complete multi-material component.
Developing a soft-touch surface or a part around a preformed insert? Explain the base component and the intended result together. A useful brief identifies what already exists, what will be added and which decisions remain open.
Include in your enquiry
- Base-part or insert drawings, material and revision.
- Areas to cover, leave exposed or protect during manufacture.
- Functional, appearance and assembly requirements for the finished component.
- Who supplies the base parts or inserts, and who approves samples.
Buyer questions
Can the enquiry include buyer-supplied inserts?
Describe the inserts, their available documentation and intended supply arrangement. Confirm responsibilities and handling requirements during review; do not assume supplied components are already approved.
What if I am unsure which process to request?
Share drawings or photographs and describe the intended function. Discuss the process scope and unresolved material questions before requesting a final quotation.
