Thermoformed Shell Product features: Saves raw materials, lightweight, convenient transportation, meets environmental protection and green packaging requirements; can package any irregularly shaped products without adding buffer materials; the packaged product is transparent and visible, beautiful in appearance, easy to sell, suitable for mechanized and automated packaging, convenient for modern management, saving manpower and improving efficiency. For example, the blister tray is protective, transparent, intuitive, easy to use, lightweight, and commonly seen in life. TV shell thermoforming 。

Compared with other materials, thermoformed shells have the following characteristics: chemical resistance; glossy, partially transparent or translucent; most of them are good insulators; lightweight and strong; easy to process, mass production, low price; wide range of uses, multi-functional, easy to color, partially high temperature resistant
Thermoformed Shell They are also divided into general-purpose plastics and engineering plastics, which are mainly defined by their wide range of uses. For example, polyethylene and polypropylene are inexpensive and can be produced on many different types of machines. Engineering plastics are expensive, but the stability and physical properties of the raw materials are much better. In general, they are both rigid and tough.
In the processing and production of blister factories, especially in the customized production of products, various situations always occur, and errors are inevitable. So, for thermoformed shell factories, what are the thermoformed shell problems we often talk about? Most of the blistering problems we often talk about are the following problems:
Common problems in thermoformed shells:
Thermoformed Shell Insufficient thermoforming means that the shape is deformed, and the product with the same shape as the mold is not thermoformed.
Excessive bubbling means the product is too thin;
Pulling lines refers to unwanted line marks appearing on the molded product; uneven thickness.

Thermoforming processing Let me tell you, these problems need to be debugged on site after the mold is made, including: sheet feeding time, heating temperature and time, vacuum strength and time, descending position, upper mold time and depth, the placement position of the mold in the layout, whether to add accessories between molds, etc.
