Heated draw pins – for special effects
Heated draw pins are used in various areas of synthetic fibre production. Ideal for two-step processes, special effects such as thick/thin or light/dark areas are created with this stationary, fixed, non-rotating heating element. Retech heated draw pins are available in different shapes and with various surface treatments and structures.
Advantages
• Accurate surface temperature (for consistent yarn quality)
• Extended life of surface
• Exchangeable sleeves with recoverable surface
Characteristics
• PT100 temperature sensor with monitoring sensor for over-temperature protection
• Diverse surface materials available (chrome or ceramic)
• Diverse surface finishes available (smooth, knurled or orange peel)
Technical specifications
• Temperature: 60 - 250 °C
• Speed: up to 1000 m/min
• Roll diameter: 40 - 80 mm
• Supply voltage: 115/230 V
• Frequency: 50/60 Hz
• Installed power: 70 - 300 W
Plate heaters and ovens – convection or contact
Plate heaters are available either as contact or convection solutions in various standard lengths, or as special plate heaters or ovens with unique design, temperature profile and high temperature options up to 500 °C. The ovens, in contact or convection type, are either resistance or infrared heated with options to heat from bottom and top. They can be executed for production machines or for lab-line solutions.
