What are the key points when customizing PET blow molds for OEM production?
• Confirm mold material as aluminum alloy or steel; match cavity count to output rate.
• Require preform heating curve and blow pressure parameters.
• Mold cooling channel design must ensure wall thickness variation ≤0.2mm.
• OEM contract must clarify mold ownership and drawing confidentiality.
• At acceptance, test neck dimensions, volume and pressure resistance per GB or ISO.
