Today, the editor of Jiuzhi.com analyzes the characteristics of plastic thermoforming processing. The characteristics are as follows:
1. Adaptability. By thermoforming, it is possible to produce various large, extra small, extra-thick and ultra-thin articles. The thickness of the sheet (sheet) used as raw material can be as thin as 1~2mm or even thinner; the surface area of ​​the product can be as large as possible. 10m2, belonging to the semi-shell structure, can be as small as a few square millimeters; the wall thickness can reach 20mm, as thin as 0.1mm, such as the product of thermoforming a tablet. Thermoformed articles are mostly concave and convex half-shell-shaped, and their depth is limited.
2. A wide range of applications. Due to the adaptability of thermoformed parts, their application range is large. From the packaging of the tablets to the refrigerator liner, and even to the aircraft cabin cover, it can be obtained by thermoforming. The types of products include cups, saucers and other household utensils, electronic instrument accessories and TV casings, billboards, bathtubs, toys, packaging utensils, and the like. There are also automotive parts, building components and aircraft cabin covers.
3. Equipment investment is small. Because the thermoforming equipment is simple. Moreover, the required total pressure is not high, and the requirements for the pressure equipment are not high, so the thermoforming equipment has the characteristics of low investment and low cost.
4. The mold is easy to manufacture. The thermoforming mold has simple structure, low material cost, easy manufacturing and processing, low requirements on materials, and convenient manufacture and modification. It can be made of steel, plastic, stone and other materials, and the cost is only 1/10 of the injection mold, and the product The design changes quickly and is suitable for the production of small batch parts.
5. High production efficiency. When using multi-mode production, the output per minute can be as high as 100 pieces.
6. High waste utilization rate. Since most thermoforming methods produce scraps, producing round products with sheets or films can produce 50% or more of the scrap, while producing rectangular products can also produce 25% of the scrap, in order to avoid waste. Mix these scraps with new materials.
