Manufacturing Process

The Geyser Plastic Terminal Block Cover is manufactured through a controlled plastic injection moulding process.

1. Product Design

The cover is designed according to the terminal block dimensions, electrical connection arrangement, cable-entry requirements, mounting points, wall thickness, clips, bosses, and clearance requirements.

2. Material Selection

A suitable thermoplastic material is selected according to the required electrical insulation, temperature resistance, impact strength, dimensional stability, and application requirements.

3. Plastic Preparation

The selected plastic granules are prepared according to the material manufacturer's processing specifications and fed into the injection moulding machine.

4. Injection

The plastic is heated and converted into molten material before being injected into the mould cavity under controlled pressure and temperature.

5. Filling and Packing

The molten plastic fills the mould cavity and holding pressure is applied to maintain the required geometry and dimensional accuracy.

6. Cooling

The mould cooling system removes heat from the component until it reaches sufficient rigidity for ejection.

7. Ejection

After cooling, the mould opens and the finished terminal block cover is removed using the designed ejection mechanism.

8. Finishing and Inspection

The component is inspected for flash, warpage, short shots, sink marks, surface defects, dimensional accuracy, cable-entry openings, and assembly fitment.

Mould Manufacturing Process

The Geyser Plastic Terminal Block Cover Mould is manufactured according to the component geometry, terminal-block arrangement, production quantity, injection machine capacity, and required mould life.

1. Product and Mould Design

Customer drawings, 3D CAD models, or approved samples are used to develop the mould. The cavity, core, parting line, gates, runners, cooling channels, and ejection system are designed according to the component.

2. Mould Material Selection

Suitable mould steel is selected according to production volume, expected mould life, dimensional requirements, component complexity, and required surface finish.

3. Precision Machining

The cavity, core, inserts, cable-entry features, mounting details, and other mould components are manufactured using CNC machining, EDM, drilling, grinding, and precision finishing processes.

4. Cooling System

Cooling channels are designed to provide controlled and uniform cooling and help minimize dimensional variation.

5. Ejection System

Ejector pins, ejector plates, inserts, or other suitable mechanisms are incorporated according to the terminal block cover's geometry.

6. Mould Assembly

The cavity, core, inserts, guide components, cooling system, runner/gating system, and ejection system are assembled and aligned.

7. Mould Trial

Trial production is performed to evaluate filling, cooling, ejection, cable openings, dimensions, surface finish, warpage, and assembly fitment.

8. Final Tool Correction

Any modifications identified during the mould trial are completed before the mould is released for regular production.

Raw Materials

Material selection should consider the terminal cover's electrical insulation requirements, operating temperature, flame resistance, mechanical strength, dimensional stability, and customer specifications.

Potential materials include:

• PP – Polypropylene

• ABS – Acrylonitrile Butadiene Styrene

• PC/ABS – Polycarbonate ABS Blend

• PA – Polyamide/Nylon

• PBT – Polybutylene Terephthalate

• Flame-retardant engineering thermoplastics

• Heat-resistant plastic grades

For electrical applications, the final material should be selected according to the required electrical, thermal, flame-retardancy, and safety specifications.

Quality Control

Quality control can include inspection of:

• Overall length, width, and height

• Terminal block clearance

• Cable-entry dimensions

• Wall thickness

• Mounting-hole dimensions

• Screw boss dimensions

• Clip and locking dimensions

• Surface finish

• Colour consistency

• Warpage and deformation

• Flash and burrs

• Sink marks

• Short shots

• Cracks

• Assembly fitment

• Wire-routing clearance

• Batch-to-batch dimensional consistency

Where specified, the component can also undergo electrical insulation, temperature resistance, or flame-retardancy verification according to applicable customer requirements.

Production Capacity

Production capacity depends on product weight, mould cavity count, injection moulding machine capacity, plastic material, mould design, cycle time, and production efficiency.

For example, a single-cavity mould operating with a 20-second cycle has a theoretical output of approximately 180 pieces per hour, before accounting for machine downtime, inspection, material handling, mould maintenance, and other production losses.

Multi-cavity moulds can be considered for higher-volume production where technically suitable.

Actual production capacity should be finalized after reviewing the terminal block cover's product weight, dimensions, mould configuration, machine capacity, and required production volume.
