Engineering Overview: The “Double-Row” Productivity Multiplier<\/h2>\n

In the high-volume production of small-format containers\u2014such as pharmaceutical vials, hotel amenities, and mini-liquor bottles\u2014cycle time is only half the battle. The real victory lies in cavitation density. As an engineer who has spent two decades optimizing One Step Blow Molding Machine<\/a> layouts, I present the HGY250-V4-B<\/strong>. This is not just a standard machine; it is a “Double-Row” (Double Bank) powerhouse designed to effectively double your output per footprint.<\/p>\n

The HGY250-V4-B operates on a 4-station rotary indexing system but utilizes a specialized mold layout that accommodates two rows of cavities. This allows for an astounding 16 to 28 cavities<\/strong> for bottles under 100ml, while maintaining a robust 300KN Injection Clamping Force<\/strong>. By injecting a massive theoretical shot weight of 680g<\/strong>, this machine is specifically engineered for manufacturers who need to produce millions of units of high-quality, flash-free PET or PETG containers annually without investing in multiple standard machines. It is the ultimate high-efficiency solution in the ISBM Machine<\/a> sector.<\/p>\n<\/div>\n

Core Technology: 4-Station Double-Row ISBM Process<\/h2>\n

The One Step PET Bottle Machine<\/a> maximizes quality by controlling the polymer’s thermal history. The HGY250-V4-B employs a unique 4-station process that handles two rows of bottles simultaneously, doubling throughput without sacrificing precision.<\/p>\n

\"4-Station<\/div>\n
\n
\n

1. Double-Row Injection<\/h3>\n

Molten PET is injected into a double-row cavity plate. The 300KN clamping force<\/strong> and 680g shot capacity ensure equal pressure across all 28 cavities (in max configuration), preventing short shots.<\/p>\n<\/div>\n

\n

2. Uniform Conditioning<\/h3>\n

The double row of preforms is transferred to the conditioning station. Advanced thermal regulation ensures that inner and outer rows receive identical heat profiles for consistent stretching.<\/p>\n<\/div>\n

\n

3. Precision Stretch & Blow<\/h3>\n

Stretch rods extend the preforms axially while 2.0-3.5 Mpa air expands them. The 250KN Blow Clamping Force<\/strong> ensures zero parting lines, even when molding 28 bottles at once.<\/p>\n<\/div>\n

\n

4. Mass Ejection<\/h3>\n

Finished bottles are stripped from the lip molds. The touchless process makes this machine ideal for high-volume pharmaceutical and food-grade applications.<\/p>\n<\/div>\n<\/div>\n
