Energy Saving PP Strap Making Machine 280kg/h

PRODUCT OVERVIEW

On a strap line that runs three shifts, electricity is the second largest cost after resin. This PP strap making machine is engineered around 280kg/h output with variable frequency drives on every unit and an intelligent temperature system that heats to set point and then cuts back automatically.

The result is a lower and, more importantly, more predictable kWh figure per ton of 5-25mm strapping band. Even plasticization at reduced power also protects the melt from overheating, which shows up directly in strap tensile strength and elongation.

Where the Energy Savings Come From

• VFD on each driven unit: motors draw only the power the current speed needs, instead of running flat out against a throttle.
• Intelligent temperature control: the oven reaches set temperature and stops heating until heat is needed again.
• Insulated heating zones: less heat lost to the workshop, so the oven holds temperature with shorter heating cycles.
• Even plasticization: a correctly matched screw profile melts the resin with less shear heat and fewer rejects.
• Non-stop screen changer: production continues while filtering, avoiding the reheat cost of a full stop and restart.
• Automatic winding: fewer starts and stops on the haul-off, which is where peak current spikes come from.

Performance of the Energy Saving PP Strap Line

Advantages Beyond Power Cost

• Lower cost per ton: energy savings land directly in the margin of every coil you sell.
• Stable quality: controlled heating protects tensile strength and elongation through a long shift.
• Less downtime: fewer rejected metres and fewer heating element failures.
• Predictable bills: reduced peak load makes the electricity figure easy to budget.
• Cleaner workshop: reduced heat loss means a cooler, safer production floor.

Production Process

Raw material intake → mixing → pre-drying → melting and extrusion → water cooling and shaping → oven heating → first stretching → second stretching → embossing → oven tempering → cooling → automatic winding.

Typical Applications

Continuous strap production for carton plants, packaging distributors and industrial packing lines where power cost and long run quality both matter.

Service and Support

We record the actual running power of your configuration before shipment and share the figures, so the saving is measurable rather than claimed. Installation guidance, operator training and remote diagnosis are included.

FAQ

Q: How much power does the line actually use?
A: It depends on strap size and running speed; we measure and report the figure for your configuration before shipment.

Q: Do VFD drives affect strap quality?
A: No, they stabilise speed control, which makes width and thickness more consistent.

Q: Is recycled material still possible?
A: Yes, with clean, pre-dried recycled PP flakes and the matched screw configuration.
