Manufacturing Process

The Geyser Plastic Inner Tank Top Cap is manufactured through a controlled plastic injection moulding process.

Step 1 – Product Design

The required component dimensions, wall thickness, mounting points, openings, ribs, bosses, clips, and other design features are finalized.

Step 2 – Material Selection

A suitable thermoplastic is selected based on mechanical strength, temperature requirements, dimensional stability, electrical requirements, and the intended application.

Step 3 – Plastic Injection

Plastic granules are fed into the injection moulding machine and heated until they become molten plastic.

Step 4 – Mould Filling

The molten plastic is injected into the precisely machined mould cavity under controlled pressure and temperature.

Step 5 – Cooling

Cooling channels in the mould help the molten plastic solidify while maintaining the required component geometry.

Step 6 – Ejection

After sufficient cooling, the mould opens and the finished plastic top cap is ejected using the mould's ejection system.

Step 7 – Finishing and Inspection

The component is checked for flash, deformation, dimensional accuracy, surface defects, and assembly fitment.

Mould Manufacturing Process

The mould for the Geyser Plastic Inner Tank Top Cap is manufactured according to the product design and expected production volume.

1. CAD and Mould Design

A 3D CAD model is used to develop the mould structure, including cavity, core, parting line, runners, gates, cooling channels, and ejection system.

2. Mould Material Selection

Suitable mould steel or other appropriate tooling material is selected according to production volume, product requirements, and expected mould life.

3. Precision Machining

Mould components are manufactured using processes such as CNC machining, EDM, drilling, grinding, and precision finishing.

4. Mould Assembly

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

5. Mould Trial

Trial production is conducted to evaluate filling, cooling, ejection, dimensions, surface finish, and overall component quality.

6. Final Correction and Approval

Any required tooling corrections are completed before the mould is released for regular production.

Raw Materials

The plastic material for the Geyser Plastic Inner Tank Top Cap is selected according to the product's technical requirements. Potential material options may include:

• Polypropylene (PP)

• ABS

• Polycarbonate (PC)

• Polyamide / Nylon (PA)

• Engineering-grade thermoplastics

• Heat-resistant plastic grades

• Flame-retardant plastic grades, where required

The final material should be selected according to the component's operating temperature, mechanical load, dimensional requirements, electrical safety requirements, and customer specifications.

Quality Control

Quality control is carried out to help maintain dimensional consistency and reliable product performance.

Inspection parameters may include:

• Overall dimensions

• Critical mounting dimensions

• Opening and hole dimensions

• Wall thickness

• Rib and boss dimensions

• Surface finish

• Warpage and deformation

• Flash and burrs

• Cracks and moulding defects

• Material consistency

• Assembly fitment

• Batch-to-batch consistency

Where required, customer-approved drawings and specifications can be used as the basis for inspection.

Production Capacity

Production capacity depends on several factors, including injection moulding machine capacity, mould cavity count, component weight, material, mould design, cycle time, and production efficiency.

For example, a 4-cavity mould with a 30-second cycle has a theoretical capacity of approximately 480 pieces per hour, before considering machine downtime, material handling, inspection, mould maintenance, and other production factors.

Actual production capacity is determined after evaluating the final product design, mould configuration, machine specifications, and required production schedule.
