Jwell
Polystyrene (PSP) sheet extrusion lines are specialized production systems designed to manufacture PSP sheets, widely used in packaging, construction, and other industrial applications due to their light weight, thermal insulation, and ease of processing. Here is an introduction to the components and features of Jwell PSP sheet extrusion line:
1. Raw Material Handling and Feeding:
- Raw Material Storage: High-quality polystyrene pellets or granules are stored in silos or hoppers.
- Feeding System: An automated feeding system delivers the raw materials consistently into the extrusion system.
2. Extrusion System:
- Extruder: The core machine where PSP granules are melted and mixed. It typically features a single or twin-screw design optimized for polystyrene processing.
- Temperature Control: Precise control of the barrel and screw temperatures is crucial for consistent melting and mixing.
3. Die Head and T-Die:
- Die Head: Shapes the molten PSP into a flat sheet. The die design influences the sheet thickness and width.
- T-Die: Ensures uniform melt distribution, forming a sheet with consistent thickness across its width.
4. Calendering Unit:
- Calender Rolls: A series of rollers that further shape and cool the PSP sheet. The gap between the rolls can be adjusted to control the sheet thickness.
- Temperature Control: The rolls are temperature-controlled to ensure even cooling and smooth surface finish.
5. Cooling and Haul-Off Unit:
- Cooling Rollers: Additional rollers to cool the sheet to ambient temperature, enhancing dimensional stability.
- Haul-Off System: Pulls the sheet through the extrusion line at a controlled speed, maintaining consistent tension.
6. Edge Trimming and Slitting:
- Edge Trimmers: Cut off the edges of the sheet to ensure uniform width.
- Slitting Unit: Cuts the sheet into desired widths as per specific application requirements.
7. Embossing (Optional):
- Embossing Rollers: Imprint patterns or textures onto the PSP sheet surface, adding functional or aesthetic features.
8. Annealing and Flattening:
- Annealing Oven: Relieves internal stresses in the sheet and stabilizes its dimensions.
- Flattening Rolls: Ensures the sheet remains flat and free from warping.
9. Winding and Stacking:
- Winding Unit: Rolls the finished sheet into coils for easy handling and transportation.
- Stacking System: Alternatively, the sheets can be cut to length and stacked.
- Versatility: Capable of producing PSP sheets of various thicknesses, widths, and surface finishes.
- Precision Control: Advanced control systems for temperature, pressure, and sheet thickness to ensure high-quality output.
- Customization: Ability to incorporate additives for different properties such as UV resistance, anti-static, and flame retardancy.
- Efficiency: High-speed production with minimal downtime for maintenance and material changeovers.
- Safety: Equipped with safety features to protect operators and ensure safe operation.
PSP sheets produced on these lines are used in various sectors, including:
- Packaging: Food containers, trays, and protective packaging.
- Construction: Insulation panels, decorative panels, and formwork.
- Industrial: Display boards, signage, and thermoformed parts.
- Consumer Goods: Hobby and craft materials, disposable items, and household products.
Jwell PSP sheet extrusion lines are sophisticated systems designed to produce high-quality polystyrene sheets for a broad range of applications. These lines emphasize precision, efficiency, and versatility, catering to the diverse needs of the packaging, construction, and industrial sectors.
| Model | Extruder | Main Motor Power | Products Thickness | Products Width | Max. Capacity |
| PSP100/130 | Ø100+Ø130 | 75/90KW+75KW | 1-4mm | 520-2000mm | 300kg/h |
| PSP115/150 | Ø115+Ø150 | 90/110KW+90KW | 1-4mm | 520-2000mm | 400kg/h |
| Note: The specifications are subject to change without prior notice. | |||||
This machine has advantages of good performance, excellent specification, high stability and high output capacity. There are four kinds of specification, 65-90, 90-120, 100-130 ,115-150 which can meet customer’s requirements. Presently this machine has been well sold to Russia, America, Indonesia and other countries.
