Application of halogen heating lampsIndustrial fieldPlastic processingIn addition to being used for heating plastic preforms in bottle blowing machines, they can also be used to preheat plastic pellets during injection molding. In some large injection molding equipment, halogen heating lamps are installed near the hopper to preheat the plastic pellets before entering the injection molding machine screw, reduce the viscosity of the plastic, and make the injection molding process smoother. For example, for some engineering plastics filled with reinforcing materials such as glass fiber, preheating can improve their fluidity and improve the surface quality and mechanical properties of the products.In the thermoforming process of plastics, such as vacuum forming and pressure forming, halogen heating lamps can quickly heat plastic sheets. For example, in the process of producing plastic pallets, PVC or PP plastic sheets are placed in the heating area, heated to the softening point by halogen heating lamps, and then fit into the mold under vacuum or pressure to produce pallets of various shapes.Metal processingHalogen heating lamps can play a role in the preheating stage of metal heat treatment. For example, before quenching or tempering some small metal parts, using halogen heating lamps for preheating can make the temperature of the parts rise evenly and reduce thermal stress. Compared with traditional resistance furnace preheating, halogen heating lamps preheat faster and can effectively improve production efficiency. In the process of metal welding, it can also be used to preheat weldments and improve the quality of welded joints.Printing and packagingIn the printing industry, halogen heating lamps are used to dry ink. In high-speed web printing presses, after the paper is printed, the ink needs to be dried quickly before subsequent processing. Halogen heating lamps can be installed between the printing unit and the winding unit to quickly evaporate the solvent in the ink through infrared radiation to solidify the ink. In the packaging industry, for some packaging materials that need to be heat-sealed, such as plastic film, halogen heating lamps can provide heat to seal the film under pressure to form a packaging container.Agricultural fieldGreenhouse heatingIn greenhouses, halogen heating lamps can be used as auxiliary heating equipment. Especially in early spring or late autumn, when the temperature is low at night, the use of halogen heating lamps can increase the temperature in the greenhouse and provide a suitable environment for plant growth. Compared with traditional heating equipment, the heat radiation of halogen heating lamps can be directly absorbed by plants, promoting plant photosynthesis and growth. For example, in a greenhouse for flower cultivation, turning on halogen heating lamps at night can not only prevent flowers from frost damage, but also promote the growth and flowering of flowers.For some plant seedling processes that require specific temperature and light conditions, halogen heating lamps can provide supplementary light and heat. In vegetable seedling cultivation, such as the cultivation of seedlings of tomatoes and peppers, by adjusting the height and lighting time of the halogen heating lamp, natural light and temperature conditions can be simulated to make the seedlings grow strong.
