Luggage Plastic Sheet Extruder Machine is the core equipment in the upstream of the luggage industry chain, dedicated to the production of thermoplastic plastic sheets (such as ABS, PP, PC, etc.) required for luggage. It melts and plasticizes the granular raw materials at high temperature and extrude them, and finally cools and shapes them into sheets of uniform thickness. It is the “source production tool” for luggage shells, linings and other parts.
I. Core functions
Plasticization of raw materials
Heat the plastic particles to a molten state to form a uniform fluid.
Extrusion molding
Extrude the sheet through the mold to control the thickness and width.
Cooling and shaping
The sheet is quickly solidified through roller pressing, water cooling or air cooling system to ensure a smooth surface.
Automatic winding/cutting
Output rolls or fixed-length sheets to adapt to subsequent processing procedures.
II. Equipment structure
Extrusion system
Screw + barrel: core plasticizing component, divided into conveying section, compression section, and homogenization section.
Die system
T-type die: determines the uniformity of sheet width and thickness (accuracy ±0.1mm).
Calender roller group
Three-roller or multi-roller structure, flattening the surface and preliminary cooling.
Traction and cutting
Servo motor drive, precise control of winding or cutting length.
Temperature control system
Zone heating + cooling, precise adjustment of each section temperature (error ±1℃).
III. Core advantages
Customized production:adjustable thickness (0.3~10mm), color, hardness, to meet the needs of different bags.
High efficiency and energy saving: continuous production, single machine daily output can reach 2~5 tons (depending on the model).
Wide material adaptability: compatible with common bag plastics such as ABS and PP.
Environmental protection and low consumption: support the use of recycled materials to reduce raw material costs.
IV. Application scenarios
Hard case shell: ABS/PC sheet substrate for travel cases
Functional sheet: anti-static, antibacterial and other special bag materials.
V.Technical parameter examples
Screw diameter: common 65~120mm (determines output)
Sheet width: 500~1500mm (customizable)
Extrusion speed: 0.5~3m/min
Power: 30~100kW (depending on the model)
VI. Maintenance tips
Daily cleaning: remove residual material from the die to prevent carbonization blockage.
Monthly calibration: check the accuracy of temperature control sensor and pressure gauge.
Annual overhaul: replace wear parts such as screw and seal ring.
The luggage sheet extruder directly determines the performance and cost of luggage materials. With the trend of lightweight and recyclable, future equipment will pay more attention to thin-wall high-speed extrusion, bio-based/recycled material adaptation and intelligent temperature control technology. Whether it is a large-scale luggage factory or a supplier of special materials, it is an indispensable “board-making tool”.
