Industrial Applications

Manufacturing Process

1. Product Design & CAD Analysis – Review of knob dimensions, shaft interface, grip profile, and assembly requirements.

2. DFM & Mould Feasibility – Analysis of draft angles, wall thickness, locating features, inserts, and ejection requirements.

3. Precision Mould Design – Development of the injection mould according to the approved component design.

4. Mould Manufacturing – Precision machining and finishing of mould components.

5. Material Selection – Selection of suitable engineering thermoplastic according to application requirements.

6. Injection Moulding – Controlled injection of plastic material into the mould cavity.

7. Cooling & Ejection – Controlled cooling followed by safe component ejection.

8. Trimming & Finishing – Removal of gates, runners, and excess material.

9. Dimensional Inspection – Checking shaft interface, outer diameter, height, grip profile, and other critical dimensions.

10. Final Quality Inspection – Visual and fitment inspection before packaging and dispatch.

Raw Materials

Depending on the design and application requirements, suitable materials may include:

• ABS

• PC-ABS

• Polycarbonate (PC)

• PBT

• POM for suitable mechanical applications

• PP

• Other application-specific engineering thermoplastics

• Customized OEM plastic compounds

The final material should be selected according to the required mechanical strength, dimensional stability, grip characteristics, surface finish, cleaning requirements, and equipment-specific specifications.
