项目摘要
The laser beam lithography is widely applied to trial product. Resin pattern may required for various test, however, since heat resistant and mechanical properties of resin pattern was inferior to that of the metal.Therefore, if a resin pattern is quickly copied by the metal castings, time for trial is expected to be remarkably shortened.Then, the resin pattern was set in a plaster mold and heated up to the temperature the resin completely burnt out, then molten metal was cast in the mold. As the result, in case of the thick pattern, crack was generated in the plaster mold. However, thin pattern was able to be copied to the metal castings. The crack was generated in the mold, since coefficient of thermal expansion was higher than that of the plaster, and the gas pressure was increased by the burning.Then, effect of heating rate on the crack of the mold was investigated. In case of heating rate of mold was low, gas pressure was lowered, the mold was prevented from crack, and resin pattern was able to be copied to metal castings. New photopolymer for burning pattern in the mold are expected for further development of the process.
激光光刻在试制产品中得到了广泛的应用。然而,各种测试可能需要树脂模板,因为树脂模板的耐热性和机械性能不如金属。因此,如果用金属铸件快速复制树脂模板,预计试验时间将显著缩短。然后,将树脂模板放置在石膏模具中,加热到树脂完全燃烧的温度,然后将熔化的金属浇注在模具中。结果,在花纹较厚的情况下,石膏模具会产生裂纹。然而,薄图案能够复制到金属铸件上。由于热膨胀系数大于石膏的热膨胀系数,燃烧时气体压力增大,从而在结晶器内产生裂纹,研究了升温速率对结晶器裂纹的影响。在模具加热速度低的情况下,降低了气体压力,防止了模具开裂,树脂模样可以复制到金属铸件上。新型光致聚合物在模具中的燃烧模式有望进一步发展。
