220v 1000w Half White Plated Halogen Ir Lamp Infrared Heat Lamp Heater For Plastic Moulding Goldisgood application
Preheating application in plastic molding
Mold preheating: In the plastic molding process, mold temperature is crucial to molding quality. This 220V, 1000W half-white plated halogen infrared heating lamp can be used to preheat plastic molds. Through infrared radiation, the heating lamp can quickly make the mold reach a suitable working temperature. For example, in injection molding, when the mold temperature is low, the fluidity of the plastic melt in the mold is poor, which can easily lead to defects such as short shots and weld marks on the product. Using this heating lamp to preheat the mold can effectively improve the fluidity of the plastic melt, so that the plastic can better fill the mold cavity, thereby improving the integrity and surface quality of the plastic product.
Raw material preheating: In addition to the mold, this heating lamp can also be used for preheating some high-viscosity plastic raw materials. It can make the plastic raw material reach a suitable temperature before entering the mold, reduce its viscosity, and facilitate subsequent molding operations. For example, for some thermoplastics containing fiber reinforcements, preheating can make the fibers more evenly distributed in the plastic matrix and enhance the mechanical properties of the plastic product.
Curing applications in plastic molding
Accelerate resin curing: In some plastic molding processes using resin materials (such as thermosetting resins), heating lamps can accelerate the curing process of the resin. Infrared radiation can penetrate the resin layer, causing the molecules inside the resin to react quickly and shorten the curing time. Taking unsaturated polyester resin as an example, using the heat provided by this heating lamp can make the resin change from liquid to solid in a shorter time, improving production efficiency. At the same time, since heating is achieved through infrared radiation, it can make the resin cure more evenly, reduce the internal stress caused by uneven curing, and improve the quality and stability of plastic products.
