Abstract
Linear regression analysis of the three types of emitter was done, the mathematical model of the volumetric shrinkage and the wall thickness were obtained, the theory for optimization was provided, orthogonal test for investigation of the influence of processing parameter was designed, and the optimal injection molding process parameters were gained. Range analysis and analysis of variance were used to find out the main factors which affected the dimensional accuracy, and a theoretical basis for the production to ensure product dimensional accuracy was provided. According to the complex features of labyrinth emitter mini-channel, rapid prototyping and CNC wire cutting were used to produce precise prototype. With rapid tooling and the technology of rapidly producing, prototype emitter was manufactured. The performance of the product was verified by the hydraulic characteristics and clogging experiments.
