Working principle of Yongte Vacuum lamination machine for WPC door panel
- Heating and softening: Place the plastic sheet on the heating device and heat it to its softening point to make it plastic.
- Vacuum adsorption: Start the vacuum pump to extract the air between the mold and the plastic sheet to form negative pressure. Under the action of the air pressure difference, the softened plastic sheet is tightly adsorbed on the mold surface and fits the shape of the mold.
- Cooling and shaping: After a period of adsorption, the plastic sheet is cooled by natural cooling or auxiliary cooling device to reduce its temperature and shape it, so as to obtain a plastic product consistent with the shape of the mold.
- Demolding and removal: After cooling, the vacuum state is released, and the molded plastic product is removed from the mold by the demolding device. After subsequent treatment such as trimming, the final product is obtained.
Structural composition of Yongte Vacuum lamination machine for WPC door panel
- Rack: As the supporting frame of the whole equipment, it ensures the stability of the equipment and the installation accuracy of each component. It is generally made of metal material with sufficient strength and rigidity.
- Heating system: It is usually composed of heating plate, heating tube, temperature controller, etc. Its function is to provide uniform heat for plastic sheet so that it can quickly soften and reach plastic state. Common heating methods include resistance heating, infrared heating, etc. Different heating methods have different heating efficiency and temperature uniformity.
- Vacuum system: It includes components such as vacuum pump, gas tank, vacuum pipe, valve and vacuum gauge. The vacuum pump is the core equipment for generating vacuum, which forms negative pressure by extracting air; the gas tank is used to store a certain amount of vacuum to ensure the stability of vacuum degree during the vacuum forming process; the vacuum pipe and valve are responsible for connecting various components and controlling the transmission and on and off of vacuum; the vacuum gauge is used to monitor the vacuum degree in real time so that the operator can make adjustments.
- Molding mold: It is a key component that determines the shape and size of plastic products. According to different product requirements, the mold can be designed into various shapes and structures, such as convex mold, concave mold, concave-convex mold, etc. The materials of the mold are generally gypsum, copper, aluminum, steel, etc. Different materials have different costs, precision and service life.
- Clamping device: used to fix the plastic sheet to prevent the sheet from moving or deforming during the vacuum forming process, and ensure the close fit between the plastic sheet and the mold to obtain a good molding effect. The clamping device usually has an adjustable clamping force that can adapt to sheets of different thicknesses and sizes.
- Cooling system: After vacuum forming, in order to quickly shape the plastic product, it needs to be cooled. The cooling system generally includes cooling water pipes, cooling fans, etc., which take away the heat of the plastic by circulating water or air cooling, speed up the cooling speed, and improve production efficiency.
- Control system: realize precise control and automatic operation of various parameters of the equipment, including the setting and adjustment of parameters such as heating temperature, vacuum degree, blister time, cooling time, as well as the start, stop, fault alarm and other functions of the equipment, to ensure the stable operation of the equipment and the consistency of product quality.
Features of Yongte Vacuum lamination machine for WPC door panel
- Wide range of applications: It can process a variety of thermoplastic materials, such as PVC, PE, PP, PET, PS, etc., and can produce plastic products of various shapes and sizes to meet the needs of different industries, such as packaging, decoration, electronics, automobiles and other fields.
- High production efficiency: It has a high degree of automation and can achieve continuous production, which greatly improves production efficiency and reduces labor costs. At the same time, the cycle of blister molding is relatively short, and plastic sheets can be quickly processed into finished products.
- Good product quality: Through vacuum adsorption molding, the surface of plastic products is smooth and flat, with high dimensional accuracy, which can better restore the details and texture of the mold, and the product quality is stable and reliable. In addition, the blister process can also stretch and thin the plastic material, so that the product can reduce weight while ensuring strength.
- Low mold cost: Compared with other molding processes such as injection molding, the mold manufacturing of the vacuum blister machine is relatively simple, low cost, and short production cycle, which is suitable for small batch and multi-variety production needs. When the product needs to be updated or slightly modified, the mold modification is also relatively convenient and can respond quickly to market changes.
- Environmental protection and energy saving: During the processing, it is generally not necessary to use a large amount of chemical solvents or additives, and there is basically no waste gas or wastewater discharge, which is environmentally friendly. At the same time, the energy consumption of the blister process is relatively low, which meets the requirements of modern environmental protection and energy saving.
