Industrial Applications

Plastic junction boxes manufactured using our moulding services are suitable for:

Manufacturing Process

Our Plastic Junction Box Mould and Moulding Service follows a systematic manufacturing process to achieve reliable mould performance and consistent finished products.

Product Design & Development

Customer drawings, 3D models, box dimensions, cable-entry positions, internal wiring space, wall thickness, cover design, mounting provisions, sealing requirements, and functional requirements are reviewed before mould development.

Mould Flow & Engineering Analysis

The product design is evaluated for wall thickness, draft angle, shrinkage, gate position, cooling requirements, parting line, ejection system, ribs, screw bosses, cable openings, mounting features, and mould filling.

Mould Design

The junction box mould is designed using CAD/CAM software according to the required product geometry and injection moulding machine specifications.

CNC & EDM Machining

Mould components are manufactured using CNC machining, EDM, Wire Cut EDM, drilling, and grinding processes for accurate dimensions and high-quality mould surfaces.

Mould Assembly

Individual mould components are assembled and checked for alignment, cavity and core movement, cooling channels, ejector operation, guide systems, inserts, and proper mould closing.

Mould Trial & Sampling

The completed mould is installed on a compatible injection moulding machine and trial samples are produced for dimensional, cable-entry, cover operation, mounting, sealing, fitment, and visual verification.

Injection Moulding Production

Selected plastic material is heated and melted inside the injection moulding machine and injected into the mould cavity under controlled pressure and temperature.

Cooling & Ejection

The moulded junction box components are cooled inside the mould and carefully ejected to maintain dimensional stability and prevent deformation.

Finishing & Assembly

Excess plastic or flash is removed. Where required, cable glands, terminal blocks, connectors, screws, covers, hinges, mounting accessories, and other components can be assembled.

Quality Inspection

Finished junction boxes are inspected for dimensions, weight, cable-entry accuracy, cover operation, mounting accuracy, fitment, surface quality, and overall functionality.

Raw Materials

Material selection depends on the required electrical insulation, mechanical strength, impact resistance, temperature resistance, moisture resistance, UV exposure, dimensional stability, and intended application.

Mould Material

Production Capacity

Plastic junction box production capacity depends on product size, product weight, mould cavity configuration, injection moulding machine tonnage, cycle time, plastic material, mould design, and production requirements.

For example, if a single-cavity junction box mould operates with a 30-second cycle time, its theoretical output is approximately 120 pieces per hour. A 2-cavity mould operating at the same cycle time could theoretically produce approximately 240 pieces per hour.

Actual production capacity varies according to cooling time, machine efficiency, material handling, quality inspection, mould loading, assembly requirements, and other production conditions.

Actual production capacity is finalized after reviewing the product drawing, 3D model, product weight, mould cavity configuration, machine capacity, cycle time, material, assembly requirements, and required production quantity.
