What you are seeing now is a video of karting sports, which are mainly divided into leisure and competitive categories. The speed of leisure category can reach 60km/h, and the speed of competitive category can reach 130km/h. This puts higher requirements on the impact resistance of karting shells!

Choosing the right type of mechanical seal and material is crucial for the long-term performance of the machinery, as well as for the protection of both workers and the environment.

At present, customers use mold etching, silk screen printing, spray painting, and in mold transfer printing methods to produce company logos, but they are not firm and easy to fall off. To solve this problem, you can try our company's laser marking PE rotational molding material!
