Advantages

　　I. The rationality of thick sheet thermoforming engineering projects

　　In the packaging manufacturing process, unless you use cardboard as the packaging product, there is no other processing method that can compete with the thick-film blister processing technology in the market. The main advantage of thick sheet thermoforming is the rationality of its engineering projects. By moderately changing the molds for composite sheet materials, polyurethane foam sheet materials, and packaging and printing sheet materials, it replaces the conversion of thick-plate blister processing and molding equipment. Products with walls that are too thin can be processed with thick plates with high melt viscosity, while powders with the same wall thickness should be injected with low melt viscosity. For a small number of plastic parts, favorable mold costs are another advantage of thick blister processing. For a large number of products, the product can achieve a very thin thickness, and equipment with a high thermoforming rate is very advantageous.

　　II. A wide range of raw materials are optional for thick sheet thermoforming processing

　　Thick sheet thermoforming can produce small products such as packaging products for pills or charging batteries for wristwatches, and it can also produce very large products, such as 3-5m long garden water pools. The thickness of the molding raw materials can range from 0.05 to 15mm, and for foamed plastics, the thickness can reach 60mm. Any kind of thermosetting plastic or raw material with similar properties can be thermoformed.

　　III. Scrap material acquisition

　　Light cutting, which may lead to residue. After crushing this residual material, it will be mixed with the original raw materials, and then it can be made into sheets again.

　　In recent years, the recovery of remaining materials throughout the thick-plate blister processing process has gradually become crucial. Nowadays, after the waste materials are crushed and then mixed with the original ecological raw materials, they can be recycled and reused, which has produced a processing technology.

　　According to many standards, waste plastic and rubber products can be recycled, such as packaging products and even engineering products, but some of them still need development trends. The acquisition that can be carried out at this stage is mainly some chemical raw materials and electric energy raw materials.

　　In order to improve the recycling rate, we must work hard in the green ecology and economy of the entire processing process.

　　Disadvantages

　　I. Only single-sided or double-sided thermoforming

　　In the thermoforming process, only one surface of the sheet material is in contact with the thermoforming mold, so only one surface is consistent with the geometry of the thermoforming mold. The contour of the other surface of the product is obtained through yarn splitting.

　　II. Higher cost

　　The commonly used raw materials for thick sheet thermoforming are sheet materials with a thickness of 0.05-15mm, which are semi-finished products made from powders or granules. Therefore, compared with injection molding, the raw materials for thick sheet thermoforming will increase additional costs.
