Plastic hose production line is an integrated raw material pretreatment, extrusion molding, cooling and shaping, traction cutting, quality testing and packaging warehousing and other processes of automated production equipment. Its main components include:
Raw material pretreatment system: responsible for the drying, proportioning and transportation of raw materials to ensure the purity and uniformity of raw materials.
Extrusion molding equipment: the molten plastic raw materials are extruded into a continuous tubular form, which is the core equipment of the production line.
Mold system: Installed at the extruder outlet, determines the cross-section shape and size of the hose to ensure product consistency and accuracy.
Cooling and shaping device: Rapid cooling of the extruded thermoplastic tube to shape and maintain dimensional stability.
Traction cutting equipment: the cooled hose is continuously pulled and cut into a single hose according to the set length.
Quality inspection system: All-round quality inspection of the cut hose to ensure that the product meets the specifications.
Packaging storage system: automatically arrange, package and store qualified hose.
▏Main Production Materials
The main production materials of plastic hoses include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polytetrafluoroethylene (PTFE) and other thermoplastics. These materials have good flexibility, corrosion resistance, weather resistance and processing properties to meet the needs of different areas of hose performance.
▏Production Process Flow
The production process of plastic hose mainly includes the following steps:
1. Raw material pretreatment: drying, matching and conveying of raw materials to ensure the purity and uniformity of raw materials.
2. Extrusion molding: Raw materials are heated and melted in the extruder, and then extrusion through the mold to form a continuous tubular shape.
3. Cooling and shaping: The extruded thermoplastic pipe immediately enters the cooling and shaping device, and is quickly cooled by water bath or air cooling to make it finalize and maintain dimensional stability.
4. Traction cutting: the cooled hose is continuously pulled by the traction device and cut into a single hose according to the set length.
5. Quality inspection: The appearance, size and flexibility of the cut hose are tested to ensure that the product meets the specifications.
6. Packing and warehousing: The qualified hose shall be sorted, packed and stored in the warehouse, waiting for delivery.
▏Product Performance Characteristics
Plastic hose has the following significant performance characteristics:
Good flexibility: easy to bend and fold, easy to install and use.
Corrosion resistance: can resist the corrosion of a variety of chemical substances, extend the service life.
Weather resistance: adapt to a variety of environments, not easy to deteriorate.
High transparency: the hose made of some materials has good transparency, which is easy to observe the material in the tube.
Good processing performance: easy to cut, connect and process into various shapes and sizes.
▏Type Of Production Line
According to different production needs and product specifications, plastic hose production lines can be divided into the following types:
Single screw extrusion line: suitable for the production of small diameter, thin wall hose.
Twin-screw extrusion line: Suitable for the production of large diameter, thick wall hose, and hose requiring high mixing effect.
Multi-layer co-extrusion line: can produce hose with multi-layer structure to meet different performance requirements.
▏Introduce Key Devices
Extruder: extrusion of molten plastic raw materials into a tubular form, is the core equipment of the production line. Its performance directly affects the quality and production efficiency of the hose.
Mold system: Determines the cross-section shape and size of the hose, which needs to be customized according to product specifications and requirements.
Cooling and shaping device: ensure that the hose is cooled and shaped quickly after extrusion, and keep the size stable. Its cooling efficiency and setting effect directly affect the quality of the hose.
▏Common Problem Handling
During the production of plastic hoses, the following problems may be encountered:
Hose breakage: may be caused by poor quality of raw materials, unreasonable mold design or improper temperature control of the extruder. It is necessary to check the quality of raw materials, optimize the mold design and adjust the temperature of the extruder.
Uneven tube wall thickness: may be caused by mold wear, extruder screw speed instability or poor flow of raw materials. It is necessary to change the mold regularly, adjust the screw speed and optimize the ratio of raw materials.
The surface of the hose is uneven: it may be caused by the rough surface of the mold, the unstable pressure of the extruder or the poor cooling effect. It is necessary to polish the die, adjust the extruder pressure and optimize the cooling setting device.
▏Application Field
Plastic hose because of its excellent performance characteristics, widely used in the following fields:
Daily chemical industry: as a packaging material for shampoo, body wash, toothpaste and other products.
Medical industry: as an integral part of medical instruments such as infusion tubes and catheters.
Food industry: as food packaging materials, such as yogurt tubes, jam tubes, etc.
Chemical industry: as a pipeline for conveying corrosive substances, such as paint pipes, glue pipes, etc.
Agricultural industry: as part of agricultural facilities such as irrigation pipes and greenhouse frames.
To sum up, plastic hose production line is a set of raw material processing, extrusion molding, cooling and shaping, traction cutting, quality testing and packaging warehousing processes in one of the automated production equipment. By optimizing production parameters and maintaining equipment regularly, the efficiency and product quality of the production line can be improved to meet the market demand for high-quality plastic hoses.
