Thick sheet thermoforming As a popular industry, materials include PP, PVC, ABS, acrylic, etc. Different materials have different performance requirements for thick film blister processing. Today, we will introduce the required performance requirements for PP plastic suitable for thick sheet thermoforming material processing.

　　1. Plastic memory performance:

　　The so-called plastic memory is that: when the softened PP sheet is stretched, the PP sheet has a tendency to tighten and resist tensile force, and also a tendency to stretch as evenly as possible. This characteristic allows the product formed by the thermoforming process, if heated to the original forming temperature again, to return to its original flat shape. This characteristic has an important impact on the stretching of the plastic forming process.

　　2. Hot stretching

　　The so-called hot stretchability refers to the ability of the PP sheet to be stretched when heated, which greatly affects the shape and quality of the thermoformed product. Some thick PP thermoforming materials can be stretched by 15%~20%, and some can even be stretched to 500%~600%.

　　3. Heat strength

　　That is, PP Thick sheet thermoforming During processing, the sheet material softened by heating, with a gentle press, will form a clear outline on the thermoforming mold. On the other hand, if the plastic forming requires too much pressure, and the pressure difference provided by vacuum plastic forming is limited, it is difficult to show some subtle patterns.

　　4. Forming temperature

　　Molding temperature performance means that the sheet material used for thick sheet blister molding should have a suitable processing temperature range. When the PP sheet is heated during the thermoforming processing production, it has a softening temperature, is easy to form, and has a certain distance from its melting temperature, and the forming temperature range is wide. It cannot be formed only within a very small specific temperature range. If the temperature is too high or too low, the forming is easy to tear and collapse.

　　In our thermoforming production, many automotive products require thick sheet thermoforming, which can help us in production. Products produced by this method have good quality and are applied to many industries. Some electronic equipment plastic shells require thick sheet thermoforming, which can beautify the product appearance while ensuring quality. Next, let's take a look at the advantages of thick sheet thermoforming.

　　1. Thick sheet thermoforming Strong anti-deformation ability. Compared with other hard metals, it is not only more affordable, but also has more prominent insulation performance. Applying this technology to the production of 4S store car logos can not only reduce production costs, but also make the car logos more durable, and due to its strong anti-deformation ability, it can also save transportation and packaging costs.

　　2. Thick sheet thermoforming is produced through a series of processes in the thermoforming industry. In this process, beautification effects will be designed and produced, bringing a better visual experience to the product, such as 4S store car logos, promoting car sales.

　　3. Thick sheet thermoforming products are lighter and easier to transport. Moreover, for large-scale demand, production and delivery can be completed in a short time, which can completely make up for the defects of the cumbersome and time-consuming production process of traditional production processes.
