Consumer electronics injection molding at Fecision covers the parts that make up a device's housing, sealing, and internal structure.
Our capabilities combine precision tooling, materials suited to electronics-specific demands, and a production line that scales from validated prototype to volume.
Fecision's manufacturing capability for a consumer electronics program breaks down into the following areas:
FECISION supports design validation through rapid tooling, trial molding, and dimensional review before production — confirming resin behavior, filling, shrinkage, assembly fit, and functional tolerance with a production-representative process.
This staged approach is built to catch design issues before they reach an expensive production tool, which matters more in consumer electronics than in most industries given how often a design revises before launch.
High-cavity-count electronics molds — the kind that need to hit a production ramp without a tooling bottleneck — depend on mold-making precision. Fecision's mold shop runs CNC, EDM, and wire-EDM equipment in-house at tolerances down to ±0.002 mm, so tooling for a multi-cavity electronics production run is built, adjusted, and maintained on-site rather than queued at a separate toolmaker.
Consumer electronics connector and structural parts carry tight tolerance stacks — an insulator body that doesn't hold dimension under thermal cycling, or a housing that doesn't clear an internal component by the design margin, becomes a field return.
Fecision molds these components in POM or glass-filled nylon, chosen for dielectric stability and dimensional precision, with mold design and part tolerance handled by the same team rather than reconciled after the fact between separate tooling and molding vendors.
Material selection for a consumer electronics part has to solve three tensions at once: enough mechanical and thermal performance for the application, a cosmetic finish that matches the brand, and a cost that holds up at volume. Getting it wrong shows up later as warping, a failed drop test, or a part that's over-specified and over-priced for what it actually needs to do.

Fecision's production range — POM and glass-filled nylon (PA6+GF30, PA66+GF33) for structural and dielectric parts, LSR for sealing — covers the load-bearing and sealing side of that list directly. ABS and PC run through the prototyping stage today; a project specifying either for volume production gets that scoped and confirmed during DFM.
Water ingress and finish drift are two of the more common reasons a consumer electronics part fails after it ships — one during a submersion test, the other slowly, as a mold wears and a cosmetic surface stops matching the approved sample. Both get addressed at the tooling and material stage rather than patched afterward.
IP ratings describe two things: the first digit rates protection against dust, the second against liquid ingress. The jump from IP67 (temporary submersion to 1 meter, 30 minutes) to IP68 (deeper and longer, as the manufacturer defines and tests) usually means switching from a compressible O-ring to a molded gasket or full overmold, with tighter tolerance control on the mating surfaces. Fecision's LSR tooling holds ±0.03 mm on that mating surface — the tolerance band IP68 sealing actually depends on.
A cosmetic surface that looks right on the first article and drifts by the ten-thousandth part is usually a mold problem, not a material problem. Fecision controls finish through cavity polish level and coating applied to the tool itself, which holds a consistent as-molded surface across a full production run without a repeated secondary step — the same coating process that extends mold life on high-wear tooling, since a mold holding its finish is generally also holding its dimensions.
Fast iteration doesn't mean starting over: rapid and production tooling share the same design data and injection molding team, so lessons from trial molding carry directly into the production mold.
Mold and molding floor are one operation: the same tool that holds a cosmetic finish is built, coated, and maintained in-house, so finish consistency doesn't depend on coordinating a separate toolmaker and molder.
Mold wear is tracked, not assumed: coated inserts are built to hold both dimension and finish across a long production run — relevant for a part that needs to look and fit the same at piece 5,000,000 as it did at piece 1.
A SUS304 stainless-steel connector insert was overmolded with LSR on cold-runner, flash-free tooling holding ±0.03 mm tolerance. The finished assembly reached IP68 performance.
A connector program used rapid tooling and trial molding for assembly-fit and tolerance validation, catching a draft-angle issue before production tooling began.
A 0.8 mm cross-section LSR sealing ring for a consumer electronics brand used rapid-tooling trials to lock the gate location before the production mold was built. The production mold reached a 98% first-article pass rate.
