Germany Sports Water Bottle Blow Molding Case Study

Customer Background and Production Need

The customer is a German drinking-water and sports accessory company with more than 50 years of history. In 2017, the customer planned to expand production capacity at its Asian production base and evaluated Jonh Huah's extrusion blow molding solution for high-quality sports water bottles.

Technical Challenge

The product used a special compound based on LDPE to achieve durability and hand feel. The customer required a smooth bottle surface with minimal visible flow lines or parting marks. This required careful control of material flow, blowing pressure, mold cooling, and parison temperature stability.

Jonh Huah's Solution

Jonh Huah supplied the JHS-490F hybrid extrusion blow molding machine. The setup was tuned for blowing pressure control, mold cooling, and parison stability with the customer's LDPE compound. Servo-assisted motion helped improve mold closing consistency and surface quality.

Project Result

Testing showed that the customized JHS-490F could maintain a smooth bottle surface and stable forming quality with the special compound. The public output is 960 bottles per hour. The machine met the customer's purchasing evaluation for quality, price, and delivery flexibility, supporting its global production strategy.

Why This Solution Worked

This case depended on material trials, surface quality control, and stable machine movement. Jonh Huah tuned the process around the customer's LDPE compound and sports bottle appearance requirements. You can review more global customer cases or browse the technical FAQ.
