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: Quartz Infrared heating lamp can be designed with high power density, the infrared radiation energy emitted from quartz IR heat lamp can reach hundreds of degrees within one minute, even less time to around ten seconds. In plastics industry process, the plastics like ABS, PC, PE, PP, PS, PET, PVC, PMMA, they all can be laminated or formed in a short time under the fast response infrared heating because of their good thermoplastic properties.
