PMMA pepperballs are widely used in lighting industry. Because the transmittance of PMMA pepper balls is over 95%, which is close to that of glass balls, PMMA pepper balls have good toughness and are not easy to break, so PMMA pepper balls are widely used in lighting industry and automobile lighting field than glass balls.

The most commonly used method of PMMA pepperball is injection molding, and the diameter of PMMA pepperball is relatively large, so the injection molding machine used is a plastic machine specially used for PMMA processing. The injection molding of PMMA ball needs a clean workshop environment for processing, because the cleanliness of PMMA pepper ball is required in the field of lighting or automobile lighting, and no dust spots are allowed inside PMMA pepper ball. In addition, there can be no bubbles in the PMMA pepper ball, and it is difficult for ordinary injection molding machines to achieve such high-quality products, so PMMA pepperballs can only be processed by special injection molding machines.
