Pinning System
Pinning System ระบบควบคุมการม้วนฟิล์มให้เรียบสม่ำเสมอ
Pinning system เป็นระบบการปล่อยประจุไฟฟ้าที่จะช่วยทำให้โพลิเมอร์ไหลแนบไปกับลูกกลิ้งได้อย่างสม่ำเสมอ ไม่มีรอยพับ รอยย่น หรือ ฟองอากาศ
The pinning system provides an even, controlled application of extruded polymer to the casting roll.
Applications
- PET / BOPET
- PE Co-extrusion
- Nylon / BOPA
- PTFE
- PLAY
- CPP
Advantages
- Increased productivity
– Higher line speed - Improved quality of film
surface and CD profile - Better quality
– Clear and even surface - Less TDO break
Principle
- High voltage is applied on the wire or band electrode.
- Electrical corona discharged to the surrounding air.
- The film or sheet of positive polarity moves into the cast roll of negative polarity.
System Components
- The main components are a winder/ unwinder assembly, local switch box, X-Y frame, and an operating panel including HV
Power supply and control PC. Compose of a pinning system(Wire/Band) and Operating panel Software
