Intelligent Proportional Hydraulic & Pneumatic Control Adopted for Full-series Blow Molding Machines
2026/06/19
1. Uniform Product Wall Thickness, Lower Material Waste
Accurate micro-adjustment of blowing pressure avoids thin walls, bulges, wrinkles and other common defects of plastic bottles, jerry cans and hollow plastic parts. The wall thickness deviation of final products is controlled within ±0.02mm, greatly improving product qualification rate. Meanwhile, manufacturers can reduce raw material usage by 3%-6% for each production run, cutting direct material production costs effectively.
2. Soft Machine Movement, Less Wear and Longer Service Life
Proportional valves realize gradual pressure rise and fall instead of sudden start and stop. This soft running mode eliminates mechanical vibration and impact during mold opening and closing, protecting hydraulic cylinders, sealing rings and other vulnerable components. It reduces daily maintenance frequency and repair cost, and extends the overall service life of blow molding machines by more than 20%.
3. Easy Parameter Switching for Diversified Production
Operators can directly set production parameters on the human-machine touch screen. The proportional control system will automatically match optimal pressure curves for PE, PP, PET and other plastic materials. The machine is compatible with various products, including daily cosmetic bottles, food packaging containers, industrial chemical barrels and automotive hollow plastic accessories. It supports fast mold change and flexible switching between mass production and customized small-batch orders.
4. Adaptive Power Output, Remarkable Energy Saving Effect
The proportional hydraulic system intelligently adjusts power output based on actual working load, rather than maintaining constant high pressure like old-style blow molding machines. It cuts ineffective power consumption during standby and low-load working periods, reducing overall machine power consumption by 8%-12%. The energy-saving design helps manufacturers meet global environmental production requirements and lower long-term electricity bills.
