As precision plastic molding technology continues to evolve, two-shot injection molding has emerged as a key innovation that significantly enhances product functionality and design appeal. At baihao, a company specializing in precision plastic injection molding for consumer electronics and automotive components, we have embraced two-shot molding as a core competency—driving innovation, efficiency, and value for our clients.
Two-shot injection molding—also known as dual-material or multi-color molding—is a process in which two different plastic materials or colors are molded into a single part in two distinct stages, usually within the same cycle and mold. Compared to conventional single-shot molding, this technology allows for greater design freedom, improved product integrity, and enhanced tactile and visual quality.

baihao is equipped with a full range of state-of-the-art two-shot injection molding machines, supporting complex configurations such as rotary platen molds, stack molds, and multi-cavity systems. These machines enable high-accuracy switching between materials while maintaining production efficiency.

Two-shot molding hinges on mold precision. At baihao, we possess complete capabilities for mold design and manufacturing. Our engineering team excels in designing high-precision, high-complexity molds, optimizing factors like venting, alignment, and material bonding—all while minimizing development cycles.
