Custom product development combining silicone with plastic, metal, straps, textile, hardware and other components for more functional and differentiated product structures. We support structure review, material combination, tooling, sampling, assembly, quality control and repeat OEM/ODM production.
WHEN IT FITS
Suitable when one material alone cannot provide all required product functions.
Suitable when flexible silicone must be combined with a rigid plastic or metal structure.
Suitable when the product includes clips, rings, buckles, fasteners or other hardware.
Suitable for products combining molded parts with straps, webbing, textile or carry features.
Suitable for custom products that require multiple materials, finishes and brand-specific details.
Suitable for repeat OEM/ODM products requiring coordinated components, assembly and packaging.
PROJECT INPUTS
The complete product structure should be reviewed before tooling so that material combinations, interfaces, component sourcing and assembly requirements are confirmed early.
Sketches or 2D drawings with the product structure.
CAD files for geometry and interface review.
An existing part or assembly used as the reference.
A concept described or sketched for structure review.
A reference item showing the intended structure.
Known components and materials listed for review.
Material expectations per component.
Assembly scope and sequence expectations.
Packaging and kitting expectations per program.
Market context reviewed for materials and finish.
MATERIAL COMBINATIONS
Material selection depends on product function, structure, contact surfaces, finish, assembly and target-market requirements. Not every material pair bonds or molds together directly; the connection approach is reviewed per combination.
Flexible silicone over or around rigid plastic structures.
Silicone over metal inserts and hardware.
Molded parts integrated with straps and webbing.
Silicone combined with textile contact surfaces.
Clips, rings, buckles and fasteners integrated.
Several molded parts combined into one product.
STRUCTURE & INTERFACE
Multi-material products should be reviewed as a complete system so that interfaces, fit and assembly are resolved before tooling and production.
How components fit together reviewed as one system.
Interfaces between materials defined early.
Connections planned for strength and assembly.
Bonding or retention approach selected per pair.
Stack-up reviewed across all components.
Inserts located and held during molding.
Assembly order confirmed during sampling.
Serviceable parts reviewed where required.
BEFORE TOOLING
Overall structure reviewed as one system.
Material pairs reviewed for function and connection.
Each part geometry reviewed for its process.
Wall sections planned per material.
Tolerances agreed across components.
Fastening approach selected per connection.
Where overmolding applies in the structure.
Assembly access reviewed for feasibility.
Finish reviewed per material and contact area.
Packaging reviewed for size and protection.
TOOLING & COMPONENTS
Each step is confirmed per project. Dedicated tooling and sampling support is described on the Tooling & Sampling capability page.
The complete structure is reviewed before tooling.
Materials and components confirmed per part.
Tooling strategy set across all molded parts.
Each molded part developed with its own tooling.
First samples molded for every molded component.
Fit and interfaces reviewed across components.
Parts assembled as a trial to confirm the sequence.
The approved set becomes the production reference.
ASSEMBLY
Assembly steps should be confirmed during sampling so that fit, sequence, labor requirements and quality checkpoints are understood before repeat production.
Components prepared and checked before assembly.
Molded parts matched per the confirmed design.
Parts assembled mechanically per the design.
Bonding steps reviewed where the design requires.
Hardware installed per the confirmed list.
Straps and textile integrated per the design.
Assembled products checked for function.
Assembled products packed per the program.
REPEAT PRODUCTION
Approved samples, component specifications and assembly requirements are used as the reference for repeat production.
Molded components produced against approved samples.
Incoming components checked per the agreed criteria.
Sub-assemblies built per the confirmed sequence.
Final assembly completed and checked.
Function and fit checked on finished products.
Inspection against the approved sample.
