pc extrusion lampshade is a common lighting appliance, in the production process of raw material selection and treatment is very important. The following will introduce the relevant knowledge of raw material selection and processing of PC extrusion lampshade.

First of all, the selection of raw materials should consider the quality of PC (polycarbonate), PC materials are mainly imported, foreign brands are relatively high quality, such as Bayer, Makrolon, etc., and some domestic brands of PC material quality is uneven, so it is necessary to be careful when selecting materials.

Secondly, the disposal of raw materials is also very important. In the extrusion process, the PC material needs to go through two stages of drying and heating.

Drying: During the storage or transportation of PC materials, moisture in the air may be absorbed, causing bubbles and blemishes in the PC extrusion lampshade. Therefore, the PC material needs to be dried before extrusion. The drying time and temperature are generally adjusted according to the data provided by the supplier and the specific situation of the extruder.

Heating: During the extrusion process, the PC material needs to be heated to a certain temperature in order to form a uniform flow of material in the extrusion head. Different materials need to be heated at different temperatures, and it is generally necessary to set a constant temperature heating area in the extruder to maintain a certain heating temperature.

In addition, the dimensional accuracy and surface finish of PC extrusion lampshade are more important. In the extrusion process, it is necessary to set the appropriate die head according to different shapes and thickness, and to ensure the dimensional accuracy through certain adjustments. At the same time, the surface treatment of the mold and the selection of the die head also need to be fully considered to ensure the finish of the lamp shade surface.

In summary, the selection and treatment of raw materials for PC extrusion lampshade has a crucial impact on the quality of the final product. In actual production, different adjustments need to be made according to different requirements to ensure that the quality of the final product meets the requirements.
