Motorcycle Brake Lever Injection Molding Part

This lever-style operating component is designed for the braking systems of two-wheeled vehicles, with the main body formed by one-piece injection molding of engineering plastic. The structure features a long cantilever grip area and a triangular mounting base. The side of the base is equipped with circular through-holes and positioning bosses, allowing connection to the handlebar assembly via pins to function as a rotational pivot. The grip end is designed with a rounded ball shape to optimize finger contact area and provide a comfortable feel during operation.

For such irregularly shaped parts with slender cantilevers and concentrated stress at the root, it is crucial to control melt flow balance and holding pressure profiles during injection molding. This prevents surface sink marks, warpage deformation, or internal stress concentration caused by wall thickness differences. The coaxiality of the mounting holes, the flatness of the base mating surface, and the straightness of the grip arm directly affect the sensitivity and safety of braking operations. Therefore, gate locations and cooling channel layouts are optimized in mold design to ensure dimensional stability and mechanical strength in mass production.

Located in the Ninghai automotive parts industrial cluster in Zhejiang, our factory specializes in motorcycle accessories and rehabilitation medical equipment. We are equipped with Haitian precision injection molding machines and fully automatic video measuring instruments. We offer one-stop services ranging from UG/ProE structural design verification and mold flow simulation analysis to precision mold development. We can customize molding parameters based on the characteristics of common engineering plastics such as PA66 GF and ABS, effectively solving molding challenges for complex aesthetic and load-bearing structural parts. This ensures we meet the strict delivery standards for appearance quality and dimensional precision required by the automotive and motorcycle parts industry.
