Dual Shot Injection Molding TPE Overmolded Consumer Electronic Parts Textured Surface Custom

This dual shot injection molding service produces TPE overmolded consumer electronic parts, combining a rigid engineering substrate with a soft-touch elastomer layer in a single automated cycle. Typical parts include power tool grips, smart device covers, game controller shells, wearable bands and handheld instrument housings where grip, impact absorption and aesthetics matter.

Rotary platen tooling indexes the first-shot substrate into the second cavity, where TPE is overmolded with a controlled chemical or mechanical bond, producing a seamless two-material part without secondary assembly.

• Two-shot rotary platen system: substrate and overmold are produced in one machine cycle with precise alignment.
• TPE 30-70 Shore A overmold: soft-touch grip with adjustable hardness for ergonomic feel.
• Textured and gloss surfaces: combined finishes create premium consumer product aesthetics.
• Verified material adhesion: chemical bond grades are qualified with peel testing per program.
• Wear resistance: overmold layers withstand repeated handling, cleaning and UV exposure.
• In-mold decoration options: IMD film and pad printing can be integrated for branding.

Two-shot TPE parts from this service are used in power tools, garden equipment, smart home controllers, VR accessories, medical handheld devices, cameras and audio equipment. The dual material construction improves grip, dampens vibration, protects against drops and elevates the perceived quality of consumer electronics.

Xiamen KDT Technology Co., Ltd. has manufactured injection molds and molded parts since 2007, with dedicated dual shot experience including rotary platen tools and multi-material overmolding. Our integrated plant employs 40 to 50 engineers and operators running CNC, EDM and injection machines from 90 to 650 tons, exporting 80% to 90% of output to consumer electronics and tool brands worldwide.

We start every two-shot program with a material pairing study to confirm TPE adhesion to your substrate, then run DFM analysis covering the rotary sequence, gate balance and overmold thickness. Mold flow simulation validates both shots before steel cutting. For pilot runs, we offer single-cavity development tools that can be upgraded to multi-cavity production tools once the design is frozen.

A power tool brand in Germany uses our 2+2 rotary mold for a TPE overmolded drill handle, producing 600,000 units per year with consistent grip hardness and zero delamination in field testing. A US smart home company adopted our two-shot cover for a thermostat controller, combining a textured rear and gloss front, and cut assembly cost by eliminating a separate rubber boot.

Two-shot parts are packed in anti-static bags with EPE compartment trays to protect soft-touch surfaces, then palletized in export cartons. Every batch passes adhesion, hardness and cosmetic inspection against the golden sample, with AQL 2.5 final inspection.
