Based on our previous discussion of high-temperature resistant joint solutions using ceramic terminals and high-purity PTFE PTFE tape under extreme high-temperature and humid conditions exceeding 260°C in hot runner systems, the cost per joint is as follows:
The unit price of a high-frequency alumina ceramic terminal is approximately 1.5~5 yuan, and the cost of a single roll of high-purity PTFE PTFE tape is approximately 8~15 yuan. Only a small section of PTFE tape is needed per joint, resulting in a total material cost of approximately 3~10 yuan.
The overall cost is only half that of imported special fluoroplastic heat shrink tubing, and far lower than high-temperature potting solutions, demonstrating a significant cost-performance advantage in high-temperature scenarios exceeding 260°C.
