Silicone Keypad Tooling & Prototyping
Temco Rubber supports custom silicone keypad projects from design review through mold development, prototype sampling, and production handoff. We work from PCB layouts, 2D/3D drawings, housing geometry, target actuation force, legend requirements, and expected production volume to develop tooling around the actual product interface.
Silicone Keypad Tooling Development Capabilities
Tooling decisions are reviewed together with keypad geometry, PCB contact layout, tactile targets, finishing requirements, and intended production volume.
DFM & Geometry Review
We review key height, web geometry, wall sections, parting-line strategy, venting, draft, and demolding considerations before tooling begins.
Tactile Response Planning
Key travel and target actuation force are considered during geometry review so the prototype can be evaluated against the intended user-interface feel.
Conductive Contact Layout
Carbon-pill position and contact geometry are reviewed against the PCB layout and the project’s electrical switching requirements.
Legend & Backlight Planning
Key-top geometry, printing areas, laser-etched symbols, coatings, and backlighting concepts can be reviewed before the mold is finalized.
Engineering Inputs for a Keypad Tooling Project
A complete input package helps reduce avoidable tooling revisions and keeps the prototype focused on the actual enclosure, PCB, and user-interface requirements.
From DFM Review to Prototype Approval
A typical keypad tooling project moves through controlled design review, mold development, sampling, validation, and production readiness.
Design Review
We review the keypad, housing, and PCB interfaces and identify geometry or manufacturability issues that should be addressed before tooling.
Mold Engineering
The mold concept is developed around cavity layout, parting lines, venting, demolding, and the selected silicone molding process.
Prototype Molding
Initial samples are molded so key geometry, fit, tactile behavior, conductive contacts, and finishing requirements can be reviewed.
Validation & Revision
Prototype feedback is used to evaluate agreed dimensional, functional, visual, and electrical requirements before production release.
Production Handoff
After approval, the tooling and process settings move into the planned production workflow for recurring OEM supply.
Prototype Review & Production Readiness
Inspection requirements are defined around the product rather than assumed as one fixed checklist for every keypad.
Dimensional Verification
Critical dimensions and fit can be checked against the agreed drawing or CAD requirements.
Actuation Measurements
Key force and travel can be reviewed according to the defined tactile targets.
Contact Testing
Electrical contact behavior can be checked according to the agreed PCB and switching requirements.
Legend & Surface Review
Printed or laser-marked legends, coatings, colors, and surface appearance can be reviewed before approval.
