Precision Injection Molding
Stable production for high-quality oral-care components. Our injection operation molds handles, brush-head bases and device housings in food- and medical-grade polymers — on robotic presses running consistent, monitored cycles, inside a dehumidified workshop built for clear and white dental-grade parts.

Repeatable molding for small, detailed oral-care parts
Oral-care components are small, high-precision and produced in high volumes — toothbrush handles, brush-head bases and necks, and the housings of facial and powered devices. Cosmetic quality matters: flash, weld lines, sink marks or off-tone white/clear parts are rejected before they ever reach assembly.
Across a fleet of 280+ professional presses in an 80–350 tonne range, every press uses robotic part extraction for unmanned, consistent cycles. PC, transparent and white dental parts run in a dedicated dehumidified workshop, and in-process dimensional checks plus per-batch parameter monitoring keep output stable from first shot to last.

- Precision micro-components and multi-color / insert molding
- Dehumidified workshop for PC, transparent and white dental parts
- Robotic part extraction on every press for stable, unmanned cycles

Molding capability, in numbers
Selected equipment: HAITIAN · NISSEI · FCS · JSW injection molding presses
From dried resin to checked, traceable parts
Material prep & drying
Dehumidifying drying of PC and hygroscopic grades, with color, recipe and lot control before molding.
Injection molding
Parts run on 80–350 T presses with temperature, pressure and cycle parameters monitored per batch.
Robotic extraction & degating
Robotic take-out on every press, automatic sprue separation and protected handling to avoid cosmetic damage.
In-process checks & handover
Dimensional and cosmetic checks against the approved part, then batch-linked handover to finishing.
Cosmetic and dimensional stability, batch after batch
Oral-care parts are judged up close. We control moisture, process parameters and cavity consistency so clear parts stay clear, whites stay white, and dimensions hold across the run.
- First-article and per-batch dimensional & cosmetic checks against the approved drawing
- Dehumidified material drying for PC and transparent / white dental-grade parts
- Temperature, pressure and cycle parameters recorded and monitored per batch
- Flash, short-shot and weld-line control on A-class cosmetic surfaces
- Cavity-to-cavity consistency checks for multi-cavity molds
- Batch traceability linked to mold, material lot and production run
