紫外光固化模塑成型性研究

通过将注射成型工艺与光固化技术相结合的“化学-制造”工艺，以直径为6 mm、高为10 mm的圆柱体制品为紫外线(UV)光固化材料模塑成型目标，以成型制品的质量作为衡量标准，使用单因素方差分析方法确定辐射强度、辐射时长、灯源距模腔表面距离（简称灯距）对制品成型性的影响规律。结果表明，辐射强度、辐射时长、灯距3个工艺参数对制品的成型性有着显著的影响；制品的成型质量会随辐射强度的增强、辐射时长的延长而增大，随灯距的增高而减小。

Research of Molding Formability by Ultraviolet Radiation

A new concept named “chemical manufacturing” was proposed from the combination of traditional injection molding with UV curing. A cylinder with a diameter of 6 mm and a height of 10 mm was set as the molding goal and the weight of the products was set as standard to evaluate; a single factor analysis of variance method was used to determine the effect of the intensity of ultraviolet, the duration of ultraviolet, and the distance between UVLED device and product surface on curing and molding of the final products. The experimental results showed that the intensity of UV radiation, UV irradiation duration, and the distance between UVLED device and product surface, have significant effects on the molding of the product. The weight of the product would increase with increasing intensity of UV radiation; and would decrease with increasing UV irradiation duration and increasing distance between UVLED device and product surface.
