1) Material selection: 

ISO 9001 encourages a well-documented process for material selection. It requires clear guidelines for selecting materials based on their properties, suitability for the product's intended use, and regulatory compliance. Documented procedures help ensure consistent material quality and traceability. 

2) Material preparation: 

Under ISO 9001, procedures are established for handling, storage, and preparation of materials. This includes keeping records of material sources, ensuring proper storage conditions, and tracking the use of materials to prevent contamination or mix-ups. 

3) Melting: 

ISO 9001 emphasises process control in the melting stage, this means monitoring and documenting the temperature and pressure of the plastic material, ensuring it consistently meets the specified ISO 9001 Requirements. Any deviations are addressed promptly. 

4) Injection: 

During the Injection stage, ISO 9001 Principles highlight the importance of consistency. Process control ensures that the Injection parameters, such as pressure, flow rate, and shot size, are monitored and adjusted to maintain uniformity across multiple cycles. 

5) Cooling and solidification:  

ISO 9001 reinforces the need for controlled processes, and this applies to cooling as well. Cooling systems must be maintained and monitored to ensure that the cooling process consistently achieves the desired solidification rate and quality. 

6) Mould opening and ejection: 

The Mould opening and ejection process should be controlled and documented. This includes the maintenance and lubrication of Mould components, the speed of the ejection process, and the proper handling of ejected parts to prevent damage.  

7) Quality Control: 

ISO 9001 places significant emphasis on Quality Control. It requires the establishment of inspection and testing procedures to verify the quality of the produced parts. Inspection records should be maintained, and any non-conforming parts should be identified, segregated, and documented. 

8) Repeating the process:  

The repetitive nature of Plastic Injection Moulding makes ISO 9001 highly valuable. The standard encourages the use of standardised work instructions, training programs, and process monitoring to ensure the consistent production of high-quality parts throughout the manufacturing process.
