PET Strap Making Machine Manufacturers in Gujarat, India
A PET Strap Extrusion Line is a production line used to manufacture PET (Polyester) straps, commonly used for packaging and securing products. PET Strap Extrusion Line offered by MICRO, is suitable for making straps from 100% PET bottle flakes or 100% recycled PET strap grinders with dedicated parameters and accessories set to suit quality straps.
PET Strap Extrusion Line StraPET extrusion range for different models from 2-line machines to 8-line machines is designed perfectly by considering the customer’s exact requirements. Its extrusion capacity varies from 1,400 tons per year (200 kg. /hr.) to 6,000 tons per year (750 kg. /hr.)
Here’s an overview of the process and main components involved in a PET strap extrusion line:
- Raw Material Feeding: PET flakes, often mixed with additives for improved properties, are fed into the extrusion line.
- Drying: PET material needs to be dried to reduce its moisture content, as moisture can negatively affect the extrusion process and the quality of the straps.
- Extrusion: The dried PET material is fed into an extruder, where it is melted and homogenized. The extruder has a screw that pushes the melted PET through a die to form a continuous strap.
- Quenching: The extruded strap is quickly cooled in a water tank to solidify it. Cooling helps the strap retain its shape and achieve the desired physical properties.
- First Stretching: After quenching, the strap undergoes a first stretching process, which helps to orient the polymer molecules and enhance the strength of the strap.
- Second Stretching: A second stretching process is often performed to further improve the tensile strength and elasticity of the strap.
- Embossing: The strap may pass through an embossing unit to create a textured surface, which improves the strap’s grip and handling characteristics.
- Annealing: The strap is then heated in an annealing oven to relieve internal stresses and further improve its mechanical properties.
- Cooling: The strap is cooled again to stabilize its dimensions and properties.
- Winding: The finished strap is wound onto reels or spools for easy handling, storage, and transportation.
- Quality Control: Throughout the process, various quality control measures are implemented to ensure the straps meet the required specifications. This can include checking dimensions, tensile strength, and elongation.
Key components of a PET strap extrusion line include:
- Extruder: For melting and homogenizing the PET material.
- Die: For shaping the molten PET into a strap.
- Quenching Tank: For rapid cooling of the extruded strap.
- Stretching Units: For orienting the polymer molecules and enhancing strength.
- Embossing Unit: For creating textured surfaces.
- Annealing Oven: For heat treatment to relieve internal stresses.
- Cooling Units: For stabilizing the strap’s properties.
- Winder: For winding the finished strap onto reels.
