Blister is a thermoforming process. During the forming process, a plastic box is a process that changes from hot to cold, from molecular to fixed, and from flat to shaped. Blister in this process, can overheat, air pressure on the flat film up and down, all aspects of stretching, suction; This process is a plastic molding process.
Blister machines (high-speed machine) have a variety of types, commonly used high speed and high. This article is also about the general principle of high-speed machine about the plastic molding process.
The high-speed machine is a single-sided oven, which heats the film from the top down. The high-speed machine can meet the production needs of most daily plastic boxes. High-speed machine in the heating process, the length of time, the power consumption of the machine is a very important factor to consider. This is not only due to the consideration of the quality of plastics, but also the cost considerations. When the machine ages, the power consumption will increase (the bill of electricity for the plastic blister will be larger in the whole production process), and the large-area baking process will affect the yield of the blister because of the uneven temperature in each inch of the place.
In addition to the mechanical performance considerations of high-speed machines, there are high-speed and high-level auxiliary equipment, and the most important is the performance level of air compressors. Air compressors are used in various industries. The air-pressure equipment in the plastics industry is different from other industries. This is not only because of its huge appearance, but also because of its storage pressure. Now the minimum pressure of the blister air compressor equipment must be 100 to normal production, and then a small amount of gas, then the slightly more complex structure of the plastic blister box will be inadequate because of pressure, shape not in place. Therefore, if it is a newly established factory, it is necessary to select a high-performance air compressor in the selection of air-pressure equipment. This not only directly affects the production quality of plastics, but also determines the production efficiency and indirectly saves costs.
