| dc.description.abstract | ABSTRACT
Since the whole biotechnology industry has been developed and product functions have been improved, the features of industrial products has become lighter, thinner, shorter, and smaller. The issues of material surface and characteristics of interface are relatively important. It will be helpful for product development and product analysis when we understand the surface and interface microstructure, chemical ingredients. In order to fulfill the functionality and production line with high capacity and to achieve cost efficiency, the plastic arc-shaped design blister which contains medical grade product develops the highly valued key factor consequently.
This study focuses on the injection molding technology. Take the arc-shaped design blister container with an outer diameter of 20 mm and a depth of 7.6 mm for example, the injection molding plastic is polypropylene resin, the structure of contact area between the content HEMA lens and the blister container will result in the adherence scale after the content HEMA lens is sterilized by high pressure and heat. Therefore, this study focuses on the copy feature of cavity core surface design in the injection molding process, and then to identify the relationship between the surface roughness and adhesion by surface profiler; moreover, to investigate the impact that manufacturing condition will bring to roughness and the microstructure copy rate in means of injection molding experiments.
Experimental mold verification shows that the microstructure has an effective transfer roughness range of 0.6~0.9μm, and it has a value of 1.57 in the process capability index, according to the full factor experiment, the best injection parameter is. The mold temperature is 35 degrees, the plastic temperature is 240 degrees, the injection speed is 30 mm/s, and the clamping force is 130 ton, which is the best injection molding parameter provided for the system of this paper. | en_US |
