CONSUMER ELECTRONICS DIE / MOLD & PARTS FABRICATION
Solving Consumer Electronics Tooling Challenges with Precision Engineering
From micro-connector inserts to thin-wall TWS earbud housings and high-gloss smartphone shells, we solve micro-tolerance, thin-wall deformation, and cosmetic surface challenges for consumer electronics OEMs and ODMs.
PAIN POINT 01
Micro-Tolerance Connector & Precision Insert Machining
The Challenge
Micro-connectors and precision plastic parts demand micron-level accuracy — glass-filled compounds and tiny cross-sections cause core pin wear, flash, and dimensional drift that break ±0.002 mm critical features.
Our Solution
Jig-ground and wire-EDM inserts holding ±0.002 mm on critical features, with DLC / TiAlN PVD-coated core pins extending mold life beyond 1,000,000 shots for high-volume device programs.
PAIN POINT 02
Thin-Wall Housing Injection Deformation
The Challenge
TWS earbud shells and smartphone housings with 0.5–0.8 mm walls suffer warpage, short shots, sink marks, and ejection distortion from imbalanced flow and cavity pressure.
Our Solution
Moldflow-verified thin-wall tooling with high-flow gate design, balanced venting, and conformal cooling channels — delivering zero-warpage, dimensionally stable housings in high-volume production.
PAIN POINT 03
High-Gloss Cosmetic Surface Defects
The Challenge
Mirror-finish visible parts expose every flow mark, weld line, gate blush, and polishing deformation — rejects skyrocket when cosmetic surfaces fail class-A appearance standards.
Our Solution
Makino mirror EDM and SPI A-1 polish achieving Ra 0.05 µm with balanced gating, venting, and cavity texturing — flawless high-gloss surfaces without manual polishing distortion.
