Plastic Covers
Precision moulded plastic covers and end shrouds engineered to provide dust-tight IP protection, impact resistance, and electrical insulation across terminal blocks, bearings, gearbox output shafts, and electronic controllers.
Types & Configurations of Plastic Covers
Bearing Housing End Covers
Snap-fit yellow and black polypropylene covers protecting rolling bearings from washdown slurry.
Electrical Terminal Shrouds
Transparent or red flame-retardant polycarbonate shrouds preventing accidental live contact.
Hydraulic Valve Manifold Dust Covers
Flexible LDPE/EVA protective covers guarding sensitive proportional valve solenoids.
Gearbox Shaft Extension Protectors
Tough PA6 covers shielding rotating shaft stubs in accordance with OSHA machinery safety.
Sensor Access Port Flip Covers
Spring-loaded or tethered weather-resistant covers protecting industrial diagnostic sockets.

Material Selection & Properties
We offer specialized compound formulations tailored to chemical media, thermal extremes, static deflection, and dynamic fatigue requirements. The best material depends on your operating environment and required service life.
| Material / Polymer | Key Engineering Properties | Recommended Applications & Considerations |
|---|---|---|
| Nylon 6 / 66 (Polyamide) | High tensile strength, toughness, good sliding properties | Gears, wear pads, wire rope pulleys, bushings |
| POM (Acetal / Delrin) | High dimensional stability, zero moisture absorption | Precision gears, valve seats, fuel sender parts |
| UHMW-PE (Ultra-High Molecular) | Extremely low coefficient of friction (0.10), zero wear | Conveyor wear strips, chute liners, chain guides |
| HDPE / Polypropylene | Chemical resistance to acids & alkalis, food contact | Chemical tank flanges, pipe fittings, plating barrels |
| Polycarbonate (PC) | Optically clear, high impact strength (unbreakable) | Machine safety guards, instrument sight glasses |
