Trim & Final Line · Doors-Off / Doors-On & Body Shop
Low-friction overhead light-track rail systems and pneumatic door manipulators engineered for damage-free door removal, trim carrier transfer, and precision hinge fitting on moving assembly lines—running at major Malaysian automotive plants including Stellantis.

Modern automotive Trim & Final lines remove painted doors at the start of trim ('doors-off') and re-fit fully dressed doors near the end of the line ('doors-on'). Because a dressed front or rear door weighs 25–55 kg with glass, regulator, wiring, and trim panels—and has an offset centre of gravity—manual handling causes panel dings, hinge misalignment, and operator shoulder strain.
Ovity Sdn. Bhd. engineers complete turnkey door handling stations—combining custom pneumatic door manipulators with overhead aluminium and steel light-track X-Y rail systems and full structural load calculations. Our door manipulators and light-track modifications are running across Malaysian OEM assembly plants including Stellantis and passenger vehicle lines nationwide.
Ovity's 100% pneumatic balancers, air hoists, KH Track rails, and mechanical reaction arms operate reliably in Malaysia's high shop-floor heat and humidity, require zero expensive imported servo drives or PCB boards, and are supported directly by our Puchong engineering and fabrication team.
Every Ovity system is engineered and supported from Puchong, Selangor around your payload (kg), torque (Nm), overhead span, conveyor height, and cycle-time requirements.
| Typical Payload Range | 20 kg – 85 kg (front/rear doors, tailgates, bonnets/hoods, and commercial vehicle cab doors) |
|---|---|
| Mounting Options | Column Pedestal / Overhead Fixed / Overhead Light-Track X-Y Rail (Aluminium or Steel Profile with Hanger Structure) |
| Rotation & Tilt | 360° swivel with ±15° fine pitch/roll adjustment for hinge pin and striker alignment |
| Control System | Pneumatic Zero-Gravity Auto-Balance or Dual-Balance with fingertip up/down and parking brake |
| Safety Standard | Anti-drop check valve + part-present interlock + DOSH ergonomic compliance |
| Air Supply | 6–7 bar clean dry compressed air |
| Local Support | Designed & fabricated in Puchong, Selangor |
Proven on Malaysian assembly lines. Ovity systems—including our KH Track overhead rails, Zero-Gravity Air Balancers, Pneumatic Air Hoists, DC Torque Reaction Arms, and manipulators at Chery Shah Alam, Perodua EV, Stellantis, and Kia lines—are engineered and supported locally from Puchong, Selangor.
