Description
Technical Field
[0001] This utility model relates to the field of PC board manufacturing technology, and in particular to a PC board thermoforming machine. Background Technology
[0002] A PC sheet thermoforming machine is a device used for thermoforming polycarbonate sheets. The thermoforming machine uses a heating device to heat the PC sheet to above its glass transition temperature, making the PC sheet soft and malleable. In this state, the PC sheet is formed by molds and pressure devices, such as bending, stretching, and pressing into various shapes. After the PC sheet cools, it can be fixed into the desired shape. The glass transition temperature range of PC sheets is generally around 145-150℃.
[0003] Currently, PC boards are typically manufactured with additives such as lubricants, antioxidants, and UV absorbers. When the PC board is heated to the temperature required for thermoforming, the high temperature of the PC board and the added additives will produce a certain irritating odor. These gases can cause certain harm to human health and the environment. However, no exhaust gas cleaning components are installed during the production process. After searching, it was found that the technical solution provided by the utility model application with application number CN201922466234.6 also has the above-mentioned problems.
