Customer Background
Founded in 1993, this customer is a Tier-1 cosmetic plastic container manufacturer with over 2,500 employees and a massive 90,000-square-meter facility in Southern China. Serving high-end global beauty brands, they require packaging that exudes luxury and quality, often simulating the clarity and weight of glass. Since 2002, they have trusted Jonh Huah's Extrusion Blow Molding (EBM) technology to produce their most challenging designs, achieving a balance between premium aesthetics and manufacturing flexibility.
Technical Challenges
The production of thick-bottom PETG bottles is notoriously difficult. Unlike standard thin-walled containers, thick-bottom designs require precise control over material distribution (parison programming) to avoid "sink marks" or uneven clarity. PETG, a material with a high melt index (MI), demands a very fast and reliable machine response to maintain shape integrity during the blowing process. Furthermore, for high-end cosmetics, the surface finish must be flawless, with no discernible parting lines or optical distortions.
Our Solution
Jonh Huah implemented the JHD-370D Hybrid Blow Molding Machine, specifically customized for PETG applications. The machine’s advanced electronic control system allows for micro-adjustments in parison wall thickness, which is critical for achieving the "glass-like" thick bottom. By utilizing EBM technology instead of more expensive IBM (Injection Blow Molding) or ISBM (Injection Stretch Blow Molding) processes, we provided a much more cost-effective solution. Our EBM machines only require one set of blowing molds and allow for easy weight adjustments via the HMI touch panel, making them ideal for small-batch diversity and frequent product launches.
Results & Testimonials
The transition to Jonh Huah's hybrid system has given the customer a significant competitive edge in the cosmetic market. Their production flexibility has increased dramatically, allowing them to take on diverse, low-volume orders that were previously unprofitable. The customer noted: "Jonh Huah machines provide exceptional stability and efficiency. Their user-friendly interface allows our technicians to master the production of complex PETG bottles quickly. It’s a reliable investment that continues to pay off."
