Engineering Workflow
From material pairing to finished parts
We develop overmolded components by combining the right materials, designing the tooling, validating bonding and fit, and then moving into controlled production.
01
DFM Review
Reviewing the interfaceWe review the base part, overmold areas, wall thickness, bonding surfaces, and parting lines before tooling. Required changes help ensure proper bonding and molding performance.

Production Capabilities
What overmolding delivers
Overmolding combines multiple materials into a single component, enabling better grip, protection, sealing, cushioning, and integrated product functionality.
01
2+
Material Combinations
Combines two or more materials within a single component to create integrated rigid, flexible, protective, or functional features.
02
Custom
Material Pairing
Selects compatible material combinations based on adhesion, flexibility, durability, appearance, and product requirements.
03
± 0.05 mm*
Typical Precision
Supports consistent positioning and dimensional control across the substrate and overmolded features.
04
Custom
Colors & Finishes
Allows different colors, textures, and surface finishes to create the required appearance, grip, and user feel.
05
Medium to High
Production Volumes
Well suited for repeat production where integrated multi-material components improve product performance and assembly.
06
Integrated
Component Design
Combines multiple functions into one component, reducing separate parts while adding grip, protection, cushioning, or sealing.
Typical values shown are general industry guidelines. Actual results may vary depending on material selection, part geometry, tooling design, and processing conditions.
Surface Finishes
Every finish has a purpose.
Overmolding supports a range of surface finishes across rigid and flexible materials, from refined cosmetic surfaces to functional textures. The right finish helps balance appearance, tactile feel, grip, and comfort while complementing the overall design of the finished product.

FAQ
Questions we hear before every project
What types of products can you make with overmolding?
We can produce components that combine rigid and flexible materials, including grips, handles, controls, protective housings, and other multi-material products.
Can you combine two different materials in one product?
Yes. Suitable material combinations can be selected according to the required performance, feel, appearance, and application.
Can I get samples before starting full production?
Yes. Samples can be produced to evaluate the material combination, appearance, fit, feel, and overall product before larger production.
