Problems of China TZM Hot Runner Technology Research

TZM hot runner technology research, although there is a certain degree of development, but most of the research work or rely on experience with the introduction of foreign TZM hot runner mold to achieve, a strong dependence on the experience and long design cycles, TZM hot runner mold design iterations The possibility increases, resulting in higher costs overall design. These studies major problems exist in the following two aspects:
1. Expression of hot runner design knowledge is not standardized and unified forms vary, difficult to effectively describe the runner's knowledge and design methods, problems encountered during the design of hot runner solutions making it difficult for good.
2. Existing computer-aided research mainly focuses on the analysis of temperature field injection products, rather than their own hot runner temperature field analysis of system structure, it is difficult to analyze temperature distribution within the system of the plastic melt, it is difficult to pass temperature field to determine the reasonableness of the structural design of the runner.
