Speaking of Thick sheet thermoforming the principle, we must first explain what thermoforming is. I believe everyone has blown up balloons. Pressing the balloon firmly with both hands, covering it with your mouth, and sucking hard, you get a round balloon (product). Thick sheet thermoforming involves heating a roll of flat sheet at high temperature and using vacuum suction to adhere it to the mold surface. This is the origin of the word "suction." Then, the mold is cooled and fixed. Let's take a closer look at the principle of thick sheet thermoforming molds!

　　In fact, the high-temperature softened thick sheet thermoforming can produce products of different shapes according to the shape of the mold; after the thick sheet thermoforming is cooled and solidified into a product, it still has elasticity, and generally, the belt buckle can be directly demolded without separation.

　　Thick sheet thermoforming is widely used, and everyone has contact with it in daily life. However, because it is not often used in inner plastic shells, transparent sleeves, etc., one can imagine that plastic molding is used to hold things. Like cardboard packaging materials, of course, it is absolutely not used for everything. It can also be used as decoration and toy ornaments, which is rare.

　　 Thick sheet thermoforming The shapes and sizes of products used in packaging are different, and the weight is also insufficient, so the thickness of the materials used and the shape of the molds are naturally different. Answering questions about thick and thin blister molds. Molds are classified according to customer requirements and practicality, specifically including plaster molds, copper molds, aluminum molds, and rubber molds.

　　The above molds must have small vacuum holes at appropriate positions for film adsorption during molding. Plaster molds are basic, and other molds are first made using plaster molds, so theoretically, these molds can all be used to make products on a table with the same shape. The difference is that the surface of plaster molds is not smooth and is prone to cracking. In the thick sheet thermoforming industry, copper molds are more common, durable, and reasonably priced. Aluminum molds are used for products with strict requirements, and the dimensions and gloss are better than copper molds, but the price is slightly higher. Rubber molds are generally used to solve watermarks in the actual position, forming a glossy molding surface.

　　Thick sheet thermoforming is the direct forming equipment that determines the shape and size of the product. In the thermoforming process, the thick sheet thermoforming mold directly affects the product quality, production efficiency, and cost. When using a mold for molding, the part of the product surface with high quality is the surface that is in direct contact with the mold, and the structure is also clear and detailed. Therefore, a reasonably designed mold is very important. However, compared to one-time plastic molding, due to the low pressure applied to the mold, the range of materials for molds absorbed by thick sheets is wide.

　　 Thick sheet thermoforming Commonly used molding materials include wood, plaster, plastic, metal, and many other materials. Usually, based on factors such as plastic properties, sheet thickness, molding method, production batch, and mold cost, a comprehensive consideration is made before recommending a choice. Generally speaking, for products with high output, low surface roughness, and fine and complex structures, it is more suitable to use steel, aluminum, and copper metal materials to manufacture molds. Conversely, hardwood, high-strength plaster molds, or plastic materials can be used. In terms of cost, plaster molds are the cheapest, followed by copper-plated molds. The specific mold material is selected according to the specific situation. In summary, the mold is only the basis for forming various shapes through vacuum suction molding. The purpose of the buckle is to strengthen the rubber strength of the product placed inside or to change the type of blister structure such as folded products. The above situation may be boring for friends who have not been in contact with the absorber. The thick sheet thermoforming industry is like this; it is not a high-tech industry, but it requires contact.
