Now the camera is widely used in cars to record the driving situation,and it has pretty high requirments,and the barrel includes the chassis that supports the various lens elements and the cosmetic exterior. Plastic mounts, grooves, and moving portions of the lens are critical to the performance of the lens, and are machined to very specific tolerances. Our car lens barrel is also made of plastic.Plastic mounts are less expensive and of lighter weight. If the barrel is made of engineering plastic, it is produced by a highly efficient and precise method of injection molding. The interior surfaces of the barrel are also coated to protect them and to prevent internal reflection and flare.
Car camera lens barrel features:
1.Light weight and bear specific tolerance
2.High impact resistance and  good heat resistance
3.Compatible with 99% mobile phones in the market
4.Quality assurance admitted by many optical tech-giants.
