Plastic PE profile production line is a complete set of plastic processing equipment system, mainly including the following key components:
Raw material supply system: responsible for the transport of PE (polyethylene) raw material to the extruder, usually including hopper, metering feeding device, etc.
Extruder: is the core equipment of the production line, responsible for heating and melting PE raw materials and extrusion. Extruder is usually composed of screw, barrel, heating device and transmission device.
Mold system: According to the shape and size of the profile, design and manufacture a specific mold for extruding the molten PE plastic into the desired shape.
Shaping device: preliminary shaping of the extruded profile to ensure that its section shape and size meet the design requirements.
Cooling system: Usually water-cooled or air-cooled, the shaped profile is quickly cooled to improve its hardness and strength.
Traction and cutting device: responsible for pulling the cooled profile out of the mold and cutting it as needed.
Control system: Monitor and control the temperature, speed, pressure and other parameters of the entire production line to ensure the stability of the production process and product quality.
PE profiles are widely used in construction, furniture, automobiles, electronic appliances, packaging and other fields because of their characteristics of light weight, high strength, corrosion resistance and easy processing. For example, in the field of construction, PE profiles can be used to make door and window frames, partitions, decorative strips, etc. In the field of furniture, it can be used to make table legs, chair backs and other parts; In the automotive field, it can be used to make interior parts, bumpers, etc. In the field of electronic appliances, it can be used to make shells, brackets, etc.
Highly automated: The use of advanced control systems to achieve automated production and reduce manual labor intensity.
High precision: The mold design is reasonable, the extrusion process is stable, the dimensional precision of the produced profile is high, and the surface finish is good.
High efficiency: The production line runs fast and has high production efficiency, which can meet the needs of large-scale production.
Energy saving and environmental protection: The use of energy-saving heating and cooling systems to reduce energy consumption and reduce production costs.
Raw material preparation is the first step in the production of PE profiles. First of all, PE raw materials with stable quality need to be selected, and matched and mixed according to production needs. Then, the mixed raw materials are fed into the hopper and wait for the extruder to process.
In the extruder, the PE raw material is gradually heated and melted after the rotation and shearing of the screw. The heating device of the extruder usually uses an electric heating wire or an electric heating rod to achieve a molten state of PE raw materials by controlling the heating temperature and time. The molten PE plastic is pushed by the screw and extruded into the mold.
Mold is the key component of PE profile production. Design and manufacture a specific mold according to the shape and size of the profile. When the molten PE plastic enters the mold, the molding part of the mold squeezes and shapes the plastic to form the desired shape. The screw speed of the extruder and the design of the die will affect the extrusion speed and shape accuracy of the profile.
The extruded profiles need to go through a cooling shaping step to ensure that their cross-section shape and size are stable. The cooling system is usually water-cooled or air-cooled to quickly cool the profile below room temperature. The choice of cooling speed and cooling method will affect the hardness and strength of the profile.
PE profiles after cooling need to be inspected for quality, including dimensional accuracy, surface finish, hardness and other aspects of inspection. Qualified profiles will be fed into the packaging process for packaging, labeling, etc., for transportation and storage.
Plastic PE profile production line is a complete set of plastic processing equipment system, through automatic and efficient production methods, can produce PE profile products of various shapes and sizes, widely used in many fields. In the production process, it is necessary to strictly control the parameters and quality requirements of each link to ensure the quality and performance of the product.
