plastic assembly lines
ENGINEERED EFFICIENCY FOR DEMANDING APPLICATIONS
Our plastic assembly lines integrate precision tooling, real-time quality checks, and high-throughput processes to meet the demands of modern manufacturing. With capabilities in part welding, joining, and modular assembly, we deliver engineered sub-assemblies for complex industrial use cases. Our operations are streamlined for scale, efficiency, and repeatability — from prototype to production
Each assembly cell is designed for consistency, accuracy, and speed. Using advanced jigs, guided automation, and calibrated fixtures, we handle everything from multi-part integration to tight-tolerance fits. Our systems are built to reduce defects, minimize operator error, and support long-run durability across various sectors.
Assembled Plastic Components
We manage modular and final assemblies across a wide range of components, tailored to material type, load paths, and functional design.
- Sensor Modules: Fuel Tanks & Fluid Reservoirs: Assembled with fittings, caps, and pressure seals for high-load platforms.
- Air Ducts & Ventilation Lines: Joined for uniform flow and resistance to deformation in HVAC and engine systems.
- Washer Bottles & Coolant Tanks: Integrated with mounts, sight indicators, and pressure fittings.
- Seating Frame Sub-Assemblies: Assembled with brackets, hinges, and supports — ready for OEM integration.
- Battery Covers & Electronics Enclosures: Multi-part assemblies built for ingress protection and thermal safety.
- Protective Trim & Mountings: Fitted together for dashboards, consoles, rail interiors, and heavy vehicle cabins.
- Sensor Housings & Clamps: Assembled for dimensional alignment and load-bearing capacity.
- Cap Assemblies & Threaded Closures: Designed for torque retention, leak-proofing, and manual operation.
Built on Process Control
At Jairaj, process control is fundamental. We use real-time monitoring, cavity balancing, and calibrated cooling systems to maintain consistent wall thickness and part quality. Whether the part demands impact resistance, fitment precision, or long-term durability — we deliver with engineered discipline.
Applications & use cases
Plastic assembly lines are used to integrate multi-part plastic components—ideal for high-volume builds, modular assemblies, and precision fitment across diverse end-use sectors.
