Mould Design & Manufacturing

A precision injection mould is designed according to the cap geometry, selected material, shrinkage characteristics, production volume, cavity configuration, injection machine specifications, cooling requirements, and ejection method.

The mould may include:

• Core and cavity

• Parting line

• Runner and gate system

• Cooling channels

• Ejection system

• Guide pillars and bushes

• Inserts

• Venting

• Draft angles

• Snap-fit forming sections

• Thread-forming features where applicable

• Sealing-surface geometry

Material Selection

Plastic material is selected according to the cap's moisture exposure, dimensional stability, mechanical requirements, temperature conditions, surface requirements, and retention mechanism.

PP is a suitable option for many lightweight moisture-exposed components, while ABS, Nylon, or other engineering plastics may be considered where greater rigidity, dimensional stability, or mechanical strength is required.

Where the cap is exposed to hot water or steam, the selected material should be evaluated according to the actual operating temperature and appliance requirements.

Injection Moulding Production

Plastic resin is fed into the injection moulding machine and heated to the required processing temperature.

The molten plastic is injected into the precision mould cavity under controlled pressure and speed. The material fills the cap wall, retaining mechanism, grip features, sealing sections, threads, clips, and other designed details.

Cooling & Ejection

The mould cooling system helps solidify the cap while controlling shrinkage and maintaining dimensional stability.

After adequate cooling, the mould opens and the ejection system releases the cap without damaging its retention features, sealing surfaces, grip sections, or other critical details.

Finishing & Quality Inspection

After moulding, the component may undergo:

• Gate trimming

• Flash removal

• Visual inspection

• Dimensional inspection

• Inlet fitment checking

• Snap-fit testing

• Press-fit testing

• Thread inspection where applicable

• Water leakage or sealing verification where required

• Surface inspection

• Warpage checking

• Housing compatibility testing

Mould Manufacturing Process

Renovator Appliances Ltd provides complete Egg Boiler Plastic Water Inlet Cap Mould Manufacturing Services.

Mould Design

The mould is engineered according to the approved cap design with appropriate core and cavity configuration, parting line, gate location, runner system, cooling channels, draft angles, ejection arrangement, venting, and shrinkage allowance.

Special attention is given to sealing surfaces, snap-fit sections, retaining clips, threads, grip features, and water inlet alignment.

CNC Machining

Mould plates, cavity components, core components, inserts, and other tooling parts are precision-machined using CNC equipment according to the approved mould design.

EDM & Wire EDM

EDM and Wire EDM can be used for detailed retention features, narrow sections, inserts, thread-related tooling features, snap-fit geometry, and areas requiring high machining precision.

Cooling System

Cooling channels are designed to provide controlled mould temperature and support consistent dimensions, stable production cycles, and reduced risk of deformation.

Ejection System

The ejection mechanism is designed to safely remove the water inlet cap while protecting sealing surfaces, snap-fit features, threads, clips, and other critical details.

Mould Assembly & Trial

After machining and finishing, mould components are assembled and aligned. Trial moulding is conducted to evaluate:

• Plastic filling

• Gate performance

• Cooling

• Ejection

• Shrinkage

• Warpage

• Cap dimensions

• Inlet fitment

• Retention force

• Sealing surface accuracy

• Snap-fit performance

• Thread engagement where applicable

• Surface quality

Final Mould Approval

Necessary tooling corrections, machining modifications, polishing, fitting, and finishing operations are completed before the mould is approved for regular injection moulding production.

Raw Materials

The final material depends on the required moisture resistance, mechanical strength, temperature exposure, dimensional stability, surface finish, and retention requirements.

For components that may come into contact with water used in food preparation, material selection should be based on the actual application and applicable food-contact requirements.

Quality Control

Every Egg Boiler Plastic Water Inlet Cap can undergo systematic inspection to maintain accurate fitment, proper retention, moisture resistance, and consistent manufacturing quality.

Production Capacity

Production capacity depends on:

• Mould cavity count

• Injection moulding machine capacity

• Product weight

• Plastic material

• Cycle time

• Cooling time

• Cap geometry

• Mould design

• Machine utilization

• Production efficiency

For example, a 4-cavity mould operating with a 20-second cycle time can theoretically produce approximately 720 pieces per hour:

4 cavities × 3600 ÷ 20 seconds = 720 pieces/hour

This is a theoretical calculation. Actual production output may vary because of machine downtime, material loading, mould changes, quality inspection, maintenance, rejection rate, operator efficiency, and other production factors.

The final production capacity is determined according to the water inlet cap design, mould cavity configuration, selected material, injection moulding machine specifications, cycle time, and required production schedule.
