MINGDI Automatic Control Extruder Machine-PP/PS Sheet Extrusion Line Food Packages Sheet

PP/PS blister packaging sheet production line is an important part of modern production equipment, mainly used for the production of high quality PP (polypropylene) and PS (polystyrene) blister packaging sheet.

I. production line composition

PP/PS blister packaging sheet production line usually includes the following main parts:

Extruder: The extruder is the core equipment of the entire production line, which is used to heat and melt the plastic raw material (PP or PS), and extrude the molten plastic into sheets through a screw.

Die (extrusion die) : Die is an important part for plastic extrusion molding, and its structure determines the shape and size of the extrusion sheet. The die head is usually made of metal material and has a certain flow path structure.

Cooling system: The cooling system is used to quickly cool the extruded hot plastic sheet, allowing it to cure and form. The cooling system usually includes a water cooling device and an wind cooling device.

Sheet traction device: The sheet traction device is used to pull the extruded plastic sheet off the extruder and maintain a certain traction speed so that the sheet can be evenly stretched and cooled.

Cutting device: The cutting device is used to cut the extruded plastic sheet to a certain length for subsequent processing and packaging.

Tension control system: The tension control system is used to control the tension of the extruded sheet to ensure the stability of the sheet throughout the production process.

Control system: The control system is used for automatic control and monitoring of the entire production line, including the adjustment and monitoring of parameters such as temperature, speed and pressure of the extruder.

II. Application field

PP/PS blister packaging sheet has excellent physical properties and thermoplastic properties, and is widely used in various fields, such as:

• Packaging industry: Used to make a variety of blister packaging boxes, pallets, containers, etc., to protect products and enhance the appearance of products.
• Electronic industry: used to make electronic products shell, pallet and other components.
• Medical device industry: used to make medical device shell, bracket and other components.
• Automotive industry: Used for making automotive interior parts, parts packaging, etc.
