PRODUCT DESCRIPTION OF PET STRAPPINE MACHINE

PET plastic-steel strapping equipment is a specialized production line that converts recycled or virgin polyethylene terephthalate (PET) into high-strength plastic strapping through a process including melting, extrusion, stretching, shaping, and winding. PET plastic-steel strapping is widely used for heavy-duty packaging in industries such as steel, aluminum, papermaking, chemical fiber, and building materials due to its high strength, corrosion resistance, aesthetic appeal, and recyclability.

Features

1. Good tensile strength----PET strapping tape production line has the tensile strength of steel tape, good ductility, good impact resistance, not easy to break, and ensures the safety of product transportation.
2. Small elongation----Although PET strapping tape is a kind of plastic, its elongation changes very little, and its elongation is only 1/6 of polypropylene. It can maintain tension and make the expansion and contraction amount no longer change after packaging.
3. Strong temperature resistance----Experiments have proved that the melting point of PET strapping tape is about 260℃, and it can be used for a long time at 120℃ without deformation, and has good stability.
4. Good economic benefits----The density of PET strapping tape is 1.30~1.38g/cm3, which is only 1/6 of the density of steel tape (7.8g/cm3), equivalent to the length of 6-ton steel tape, and the price per unit length is relatively low.

What should be paid attention to when purchasing PET plastic steel belt production equipment?

When purchasing PET plastic steel belt production equipment, the following matters should be considered:

Comprehensively consider production needs, equipment performance, supplier strength, technical services and other aspects to ensure equipment adaptability, cost-effectiveness and subsequent production stability.

1. Clarify production needs and positioning

Capacity planning

Select equipment models, extrusion output, etc. (such as 120-200 meters/minute or more) and continuous operation capabilities according to expected output to avoid insufficient production capacity or over-investment.

Raw material type

Determine the raw materials that can be used for the PET plastic steel belt production equipment,

100% new PET crushed materials or recycled crushed materials

Product specifications and functional requirements

Specifications------width (such as 9mm-32mm), thickness (0.6mm-1.2mm), tensile strength (such as ≥1800N) and other parameters, the equipment needs to support flexible adjustment;

Function------whether embossing (increasing friction), color printing, customized tensile strength, etc. are required, some equipment needs to be additionally equipped with embossing rollers or masterbatch adding systems.

2. Pay attention to the core performance and technical parameters of the equipment

Host and extrusion system

Screw design: Prefer a screw with a large aspect ratio (such as 30:1) to ensure that the raw materials are fully melted and reduce poor plasticization (such as bubbles and broken belts);

Heating system------Use ceramic heating rings, high-temperature and high-power heating tubes, and uniform heating of the screw to avoid local overheating and decomposition of raw materials;

Extrusion volume stability------Equipped with a 100CC metering melt pump, pressure sensor and automatic adjustment device to ensure stable extrusion speed and avoid fluctuations in the width and thickness of the finished PP belt.

Stretching and shaping system

Stretching multiple-----PET plastic steel belt needs to be stretched to increase its strength. The stretching multiple is usually 3-10 times, and the equipment needs to support precise control (such as the primary stretching temperature of 80-100℃ and the secondary stretching temperature of 120-150℃);

Shaping method: The water cooling or air cooling system needs to be uniform to avoid deformation of the PET belt and affect the flatness of the winding.

Automation and control system

Intelligence: Choose PLC control system + touch screen operation interface, support real-time monitoring of parameters (such as temperature, pressure, traction speed) and fault alarm;

Energy-saving and environmental protection design

Energy-saving----Use servo motor or energy-saving motor, saving more than 30% of electricity compared with ordinary motor;

Production----High-speed operation of the machine, increase production by more than 40-50%.

Simple operation-----Reduce 1-2 people.
