Description
Extension Box with 100mm Insulation & Pressure Unit – PP Line
Product Overview

The extension box and pressure extension unit of this production line are the core components that impart high strength to PP strapping. The extension box has a total length of 6.5 meters (4m + 2.5m), with φ200mm extension rollers at HRC60 hardness, heating power of 41.6KW, and a 6KW mold temperature controller for precise roller surface temperature control.

The box features 100mm thick insulation, effectively reducing heat loss and ensuring uniform internal temperature. The pressure extension unit features a φ156mm roller driven by a 7.5KW motor, providing auxiliary stretching force for more complete molecular orientation. The unit has an adjustable temperature range of 50-250°C and a continuously adjustable draw ratio of 1.5-12 times.

The thick insulation not only saves energy but also improves the workshop environment, serving as an important guarantee for efficient and stable operation.

Key Features
  • Thick insulation: 100mm rock wool, significantly reduces heat loss
  • Energy saving: Reduces heating energy consumption, lowers operating costs
  • Temperature stability: Thick insulation isolates external interference, more precise control
  • Mold temp controller: 6KW ensures uniform roller surface temperature
  • Pressure-assisted stretching: Pressure unit provides additional stretching force
  • High hardness rollers: HRC60, wear-resistant and durable
  • Long heating zone: 6.5m length ensures sufficient preheating
  • Wide temperature range: 50-250°C for PP and modified materials
  • Safety design: Low outer wall temperature prevents burns
  • Easy maintenance: Insulation covered with stainless steel sheet, easy to clean
Frequently Asked Questions
Q: How much energy can 100mm insulation save compared to thinner insulation?
A: According to thermodynamic calculations and actual tests, 100mm insulation reduces heat loss by about 30-40% compared to 50mm, resulting in 20-30% lower overall heating energy consumption. Based on 6000 operating hours per year, the electricity savings are substantial.
Q: What is the function of the pressure extension unit?
A: The pressure extension unit applies pressure to the tape through an additional roller, providing auxiliary stretching force during the process. This makes PP molecular chain orientation more complete and uniform, further improving the product's tensile strength and toughness.
Q: How does the mold temperature controller work? Does it need an external water supply?
A: The mold temperature controller electrically heats oil or water, then circulates it through the extension rollers to maintain constant surface temperature. Typically, thermal oil is used; it requires an external power supply but no external water supply (water-type needs water).
