What are the troubleshooting tips for stretch blow moulding?

When troubleshooting stretch blow molding, first check the preform temperature to ensure it's within the optimal range, as improper temperatures can lead to poor stretch and inconsistent wall thickness. Inspect the mold for any signs of wear or damage, as this can affect the final product's quality. Additionally, monitor the air pressure used during the blowing process, as inadequate pressure can result in incomplete bottle formation. Lastly, ensure that the material feed is consistent and free from contamination to maintain product integrity.
