Blow molding parison control affects mass production quality!

The technology to control meat thickness changes quality and cost.

In blow molding, the way the resin stretches varies depending on the product shape, which can lead to uneven wall thickness in different areas. Particularly, corners and neck areas tend to become thinner, which can cause insufficient strength, deformation, and defects. At Fuji Seiko, we utilize parison control technology to optimize wall thickness according to the product shape. By ensuring sufficient thickness in necessary areas while reducing thickness in unnecessary areas, we achieve a balance between quality and cost. Benefits of parison control: - Stabilization of quality through optimization of wall thickness distribution - Improved strength in corner and high-stress areas - Reduced risk of thin-wall defects and deformation - Cost reduction through decreased material usage - Suppression of quality variation during mass production Even if there are no issues during the prototype stage, variations in wall thickness and insufficient strength may become apparent during mass production. At Fuji Seiko, we implement quality design aimed at mass production through optimal molding conditions using blow molding machines equipped with parison control. We consistently support our customers in improving their QCD from prototype to mass production.
