Features and advantages of HIPS Multi-layer plate production line:
1.High impact strength: the middle layer is made of high impact resistance to polystyrene, to ensure that the plate has good impact resistance, and is suitable for the application of high strength requirements.
2. Surface versatility:
The outer layer can perform many functions by adding special materials:
Bright surface: co-extrusion by PMMA or other materials to provide high gloss and weather resistance.
Matte or textured surfaces: decorative by embossing or special processes.
Scratch and antistatic: special surface performance through functional layer.
3,Lightweight design
The plate density is low, but it still has good mechanical properties, which is conducive to reduce the overall weight of the product.
4,Excellent processing performance
It can be processed for cutting, bending, hot forming and other processing to meet the manufacturing needs of complex shapes.
5, which is high and cost-effective
Through multi-layer design, optimize the raw material use structure (such as the use of recycled material in the middle layer) to achieve a balance of performance and cost.
HIPS multilayer plate production line basic components：
1. Raw material treatment system

2. Extrusion system
Single screw or double screw extruder: melt, mixing and extrusion HIPS material. Multilayer plate production usually requires multiple extruder machines.
Melt pump: Ensure stable material delivery and provide uniform pressure.
Net changer: filter the impurities in the molten material to ensure the quality of the finished product.
3. Allocation and co-extrusion module
Co-extrusion mold head: the melting material squeezed by multiple extruder is integrated to form a multi-layer structure through the flow channel design.
Splunt plate: evenly distribute melt to ensure each layer has uniform thickness.
4. Forming and cooling system
Calender (pressing roller set): pressing the molten material through multiple sets of rollers to form a flat multi-layer sheet.
Cooling roller set: quickly cooling plate to ensure the stability of plate size.
Side trimming equipment: remove the excess parts on both sides of the plate.
5. Traction and cutting system
Traction device: stably pull the plate to the subsequent processing area through synchronous control.
Cutting machine: according to the set size of the plate cutting, common flying knife cutting or round saw cutting.
6. Automatic control system
PLC control system: for automatic control of the whole production line, including real-time monitoring of temperature, pressure and speed.
Touch screen man-machine interface: easy operators to set and adjust process parameters.
7. Auxiliary equipment
Electrostatic eliminator: to prevent electrostatic accumulation on the plate surface.
Reder or stacker: roll or stack the finished sheet.
Advantages and features of HIPS Multi-layer Plate Extrusion Line:
1. Excellent mechanical properties
High impact resistance: HIPS materials have excellent impact resistance, especially in the multi-layer co-extrusion through the functional layer design, to further enhance the overall strength.
Combination of toughness and rigidity: the multi-layer plate structure can achieve the optimal ratio of surface rigidity and core toughness.
2. Excellent appearance and excellent quality
High gloss surface: through the co-extrusion process and surface treatment, the production of the plate surface is smooth and has a high gloss.
Color diversity: Different color and pattern designs can be achieved by adding a color matrix or a functional layer.
Good surface uniformity: extrusion and calendering technology ensure uniform plate thickness and surface free of bubbles or impurities.
3. Flexible in functional design
Multilayer structure advantages:
UV antiaging materials can be added to the surface layer to improve the weather resistance.
The core layer can use foaming materials or recycled materials to reduce costs and reduce weight.
The enhancement layer can be given impact resistance or other special functions.
Flame retardant performance: the fire protection requirements for specific applications are met through the addition of flame retardant.
4. Excellent processing performance
Easy molding: the plate can be processed by hot forming, cutting, drilling and other ways to meet the production needs of complex shapes.
Low contractility: the size of the processing process is stable, not easy to warp or deformation.
Good bonding and printing performance: the surface can be easily screen printing or other decorative treatment.
5. Environmental protection and economy
Recyclability: HIPS materials are easy to recycle and help reduce environmental impact.
Cost control: the multi-layer co-extrusion process allows the use of recycled material or filler material as the core layer to reduce the overall material cost.
