The objective of this paper is to study the suitability of design and capability analysis for the multi-type CIM(Ceramic Injection Molding) that can mass-produce three-type sleeves using in a mold by conduct the experiments as well as the flow analysis.
11 minutes and 40 seconds that was about 29% of general exchange way was required to exchange 8-cavity cores and center pins on the average, and the accuracy dispersion was only ±6㎛. Therefore the mold design and manufacturing was very excellent for multi-type sleeve produce in large quantities. Yield that is more than gravity 6.0 that establish by target as result that analyze gravity of products at investigated injection conditions was each 97.88%, 92.65%, 90.32% from 8SC-OLC-OSC/LC, 6SC-ILC-ISC/LC and 4SC-2LC-2SC/LC cavity combination. The measured results of the SC, LC, and SC/LC sleeve products showed 5.46㎛, 11.41㎛, and 13.05㎛ on concentricity and 3.43㎛, 6.74㎛, and 4.16㎛ on roundness respectively.
