The choice of manufacturing process (injection molding or vacuum forming) for a robot housing depends primarily on factors such as the housing's structural complexity, dimensions, precision requirements, production batch size, and cost budget. In today's rapidly evolving robotics industry, housings serve as both the first impression and a protective barrier for the device. The choice of manufacturing process directly impacts product quality and market competitiveness. As a company with extensive experience in plastic molding, CS MFG SOLUTION, drawing on our experience with over a thousand custom robot housings, explains the applicable scenarios and selection logic for injection molding and vacuum forming. The following detailed analysis focuses on the characteristics, applicable scenarios, and comparative perspectives of the two processes
