Custom tooling and sample development for silicone products, components and overmolded structures. We support drawing review, mold structure confirmation, tooling development, first samples, dimensional and functional checks, revisions and production approval.
WHEN IT IS NEEDED
When the required product shape does not exist as a standard molded item.
When the silicone part must fit an existing product, housing or interface.
When shape, logo, color or surface details are unique to a brand or program.
When silicone must be integrated with plastic, metal or another component.
When dimensions, grip, sealing, flexibility or other product functions must be confirmed.
When an approved sample and tooling are required as the reference for repeat production.
PROJECT INPUTS
The available project information is reviewed before tooling to confirm product geometry, material, mold structure and sampling requirements.
Sketches or 2D drawings with key dimensions and sections.
CAD files for precise geometry and mold structure review.
An existing part used as the dimensional and functional reference.
The product the silicone part must fit.
A reference item that shows the intended result.
Key measurements used to scope the tooling approach.
Function defined per use: sealing, grip, protection or contact.
Material and hardness expectations reviewed before tooling.
Logos, colors and artwork reviewed for mold integration.
Market context reviewed for material and finish requirements.
PRE-TOOLING REVIEW
Reviewing these details before tooling helps reduce avoidable mold revisions and sample changes.
Geometry reviewed for moldability and function.
Dimensions and agreed tolerances confirmed before tooling.
Wall sections planned for filling, strength and feel.
Parting line placement agreed before mold design.
Draft angles and demolding reviewed.
Undercuts reviewed for release or side-action needs.
Logos and surface details planned into the mold.
Material and hardness reviewed for the application.
TOOLING DEVELOPMENT
Confirm cavity layout, parting line, insert requirements and mold approach.
Confirm silicone type, molding method and relevant material requirements.
Prepare mold structure based on approved product geometry.
Produce tooling according to the confirmed design.
Inspect the completed mold before trial production.
Prepare tooling, material and project requirements for first sampling.
FIRST SAMPLES
The first sample is used to identify whether the product structure, molding result and project requirements are ready for approval or revision.
Material prepared per the confirmed specification.
First parts molded from the new tool.
Parts removed and handled per the agreed method.
Flash trimmed per the agreed criteria.
Dimensions checked against the drawing.
Visual review for surface and detail quality.
Function and fit checked against requirements.
Color and surface reviewed against references.
REVIEW & REVISION
If adjustments are required, the sample feedback should be confirmed before the next tooling or sampling step.
Checked against the drawing and agreed tolerances.
Fit against the mating product or interface.
Function checked against the agreed requirement.
Hardness confirmed against the specification.
Color reviewed against confirmed references.
Surface finish reviewed for look and feel.
Logos and details reviewed for legibility.
Assembly with other components checked.
APPROVAL TO PRODUCTION
Typical flow: Sample Review → Required Revisions → Final Sample → Customer Approval → Production Specification Confirmation → Mass Production Preparation. The approved sample and confirmed specifications become the reference for production and repeat OEM/ODM orders.
The first sample is reviewed across the agreed criteria.
Necessary adjustments are confirmed and applied.
A final sample reflects the confirmed changes.
The sample is approved as the production reference.
Specifications are confirmed for production.
Tooling, material and process are prepared for production.
COLOR & BRANDING
Color, surface and branding details should be confirmed during sampling before production approval.
Color matched against confirmed Pantone references.
Molded textures reviewed on samples.
Finish reviewed for look and feel.
Raised logo details checked for clarity.
Recessed logo details checked for clarity.
Printed decoration reviewed per surface.
Multi-color molding planned and confirmed.
TOOLING BY PROJECT TYPE
Tooling approaches adapted to each project type.
Tooling for custom molded product programs.
Tooling for LSR injection molded components.
Overmolding tooling with substrate positioning.
Insert tooling with retention and shut-off design.
Tooling for character detail and brand features.
Tooling for technical and functional parts.
