This variable frequency blow molding equipment matches extrusion speed to real demand, an approach that lowers power consumption without sacrificing output on 10 L plastic jars. The frequency-controlled motor removes the waste of running the screw harder than the cycle requires.

A double proportional hydraulic valve extends the idea to the clamping and carriage motions, so the machine delivers smooth, efficient strokes and dependable jar quality shift after shift.

• Variable-Frequency Extrusion Motor: Screw speed follows demand electronically, cutting energy use while holding melt quality steady.
• Low Average Power Draw: The design keeps average energy consumption near 1.5 kW, easing running costs for continuous jar production.
• Double Proportional Valve: Electro-hydraulic control of pressure and flow smooths clamping and carriage motion and trims hydraulic losses.
• Stable 10 L Jar Moulding: 150 kN clamping force and a large platen keep jar moulds locked and wall thickness even.
• Clean Neck and Flash Control: Down-blowing calibration trims the neck, while a hydraulic lock removes parting-line flashes.
• Microcomputer Parison Programming: Wall thickness is regulated automatically for consistent jar weight and strength.
• Forty Mould Recipes: Stored settings make size changeover fast and repeatable.

Energy-conscious workshops producing 10 L jars for foods, paints, and cleaning products benefit most, since continuous operation makes power savings add up quickly.

It also suits producers who run mixed jar sizes and want quick, repeatable changeovers without re-tuning the machine.

Q: How does variable frequency reduce energy use?
A: The frequency-controlled motor matches screw speed to demand, so the machine extrudes only the melt each cycle needs instead of running at full load continuously.

Q: Does saving energy affect output?
A: No. Output stays steady because melt quality is maintained; the savings come from eliminating wasted screw speed and hydraulic losses.

Q: Can it mould different jar sizes?
A: Yes. The controller stores forty recipes, so jar size changes are quick and repeatable.

Q: What is the average power consumption?
A: Average energy consumption is about 1.5 kW, with a 70 kW total installed power available for peak demand.

Every unit is packed in a standard export package with an optional wooden pallet or wooden case for long-distance sea freight. The machine is CE and ISO9001:2008 certified and is supported by remote commissioning, operator training, wearing-part supply, and responsive after-sales service worldwide.
