Our
company is mainly engaged in medical inspection part mould mold making and injection
molding, including reusable PPSU gastroscope handle. The handle is a commonly used
external part of medical surgical instruments. On the one hand, it has to bear
a certain pressure, has high requirements for strength, and must be reused, so
repeated high-temperature sterilization is required. PPSU material can meet
380~400° high-temperature and high-pressure repeated sterilization , meeting the
functional requirements. The mold needs to adopt the high
temperature mold design method, and the mold design needs to add a heating
device. Combined with the mold flow analysis and the physical properties of the
material, when designing the mold, the moving parts of the slider should be set
with reasonable tolerances and fit clearances on the basis of considering the
coefficient of thermal expansion. Ensure the tolerance size requirements of the
mold and production stability. Through the combination of sc…
