Infrared radiation does not need to contact the product and does not require the intermediate medium to transfer heat.
Under the sunlight, the sunshine side is warm but the sunless side is cold. This is not due to temperature differences, but radiation heating, the heat energy of electromagnetic waves (infrared radiation) from the sun that is transferred to objects. The sun is the source of heating energy, so the infrared quartz lamps are the heating source for industrial heating process.
Infrared heating lamps are widely used in the processing of thermoplastic materials. Their efficient and precise heating characteristics make them a significant technology in modern industry, serving as an alternative to traditional heating methods such as convection or contact heating.
Infrared Heating Advantages:
High Efficiency: Infrared radiation heat transfer efficiency can reach up to 90%, which is more than 50% higher than that of hot air convection heating (30-40%).
Rapid Heating: Heating speed is 5-10 times faster than traditional methods. For example, in PVC sheet thermoforming, infrared heating reduces the cycle time from 120 seconds to 20 seconds, increasing production capacity sixfold.
Precise Temperature Control: Temperature control accuracy is ±1°C, preventing overheating or insufficient melting. For instance, the defect rate in medical catheter welding decreased from 3% to 0.2%.
Wavelength Matching: Short-wave infrared (0.8-1.4μm) is suitable for dark materials (e.g., carbon fiber-reinforced plastics), while medium to long-wave infrared (2-10μm) is ideal for transparent or light-colored materials (e.g., PC, PMMA).
Customizable Power Density: Power density can be customized up to 600KW/M².
Adjustable Radiation Distance: The distance between the infrared heating tube and the heated object can be adjusted for safety and uniformity, preventing overheating or material melting hazards.
Industry Plastic Heating Applications:
Plastic Welding and Bonding: Infrared heating lamps emit infrared radiation with strong penetration, allowing focused heating on weld seams (e.g., automotive tail lights, medical device housings). This enables rapid surface melting for seamless welding, avoiding overall heating-induced thermal deformation.
Injection Molding and Extrusion Processes: Infrared heating lamps can quickly preheat molds before injection, reducing issues like short shots or residual stress. They also efficiently remove trace moisture from hygroscopic materials like PET, preventing injection molding defects.
Thermoforming and Film Processing: In thermoforming, infrared radiation can penetrate ABS sheets up to 5mm thick, achieving synchronous heating of inner and outer layers (temperature difference <5°C), reducing uneven cooling shrinkage. In bi-axial stretching of films, infrared heating lamps can elevate the film to its glass transition temperature (e.g., PET's Tg ≈75°C) before stretching, ensuring consistent molecular orientation.
3D Printing and Composite Materials: In selective laser sintering, infrared heating maintains the powder bed at 170-180°C, reducing laser energy requirements and increasing forming speed by over 30%. Localized infrared heating can activate epoxy resin matrices for rapid curing (e.g., from 120°C to 180°C in just 2 minutes).
