The main materials for manufacturing LED lanterns are PETG, acrylic, rotary moulding and PC. Because of its wide range of applications, there are many scale types of LED lanterns. Generally, different scale types of LED lanterns have their corresponding application places, and different scale types of LED lanterns also have different production and manufacturing processes.
The LD lantern shell with a diameter of 15-50 cm is mostly made by injection moulding. The feature of this process is that the shell is divided into two halves, and the upper and lower cover of the final equipment is fixed.
The LD lantern shell with diameter of 60-80 cm is usually manufactured by blow-moulding process, which is characterized by short production cycle, one-time moulding of the shell, round appearance, good gloss and transmittance.
Injection moulding process is usually used for the LED lantern shell with a diameter of 90 cm or more. This process is characterized by the manufacture of large diameter shell, but at the same time, the quality of the lantern is also large.
