||Nd-Fe-B magnet, soft magnetic iron core and silicon steel core in the spindle motors, stepper motors, fan motors, buzzer, motor movement is extensively used, currently the required magnet, core materials, the vast some imports from the United States and Japan, currently a company of cases is there are ways to purchase directly from original raw materials and magnetic core material and the ability to self-production magnet core of the company, due to high visibility in the international market have been well-known manufacturer of magnetic MQI Japan as the world’’s top ten key support for manufacturers, production capacity has temporarily 3 ~ 5 ranking in the world. Although this magnet and the core product gross margin is not high, but the customers quality requirements of its extremely harsh, and other electrical and electronic products, such products also needs to face a market price decline, but the quality required by customers are more and more higher. Therefore, how to create cost effective control and reduce to a reasonable level, and can improve the quality of the original, has become the product can continue to maintain the competitiveness of important factors.|
In view of this, this study is standing in organize development to change the center of opinion, through employees to improve activities training and establish cross department project improve team to transmit application of QC statistic method, improve project skill, and fit it to use key point problem to analyze solving method ─ the Taguchi method, under the same conditions in the existing resources, on one hand expect core employees can change learning and behavior stratification plane in shortest time, it produce positive outstanding change. On the other hand changing in result stratification plane, deeply look forward to in the shortest time, lowest cost, most efficency, the most simple and statistics method, to help the company complete optimization product and process parameters of robust design. Improve the producing target in learning stratification plane, hope trained employees improve consciousness has outstanding progress, improve producing target in behavior stratification plane, hope qualities consciousness and solve the problems’ ability are able to outstanding elevated, in improving result, hope that output target to reduce the rate of 63% core poor, down the two main specifications of products magnet average defect rate of 16%, another goal in the outcome more than 30% want to reduce the manufacturing cost and also can improve the quality of the original level, and to reduce product variability, improve the quality of power, and thus enhance the market competitiveness are elevated and make business performance can growth a lot to reach purpose.
Improve learning and behavior stratification plane, due to limited staffs aren’t enough, thus using sampling in convenient way to draw from sample, testing mode to estimate training effects after training. Improve result stratification plane, in this study case factory set improving theme, a Nd-Fe-B magnet for two to improve product processes and themes, and the core power early book production process to improve the theme as a subject of the improvement, based on Taguchi method of experimental design principles, the three topics separate from parameter design unfold experiment plan, carry out activities, through simple random sampling in experiment, they were measured for each subject to improve the topics’ target that quality characteristic values, to see whether the experiment actually achieve the objectives target, its through engineering presume and present experiment confirm, to view whether indeed to reach target in experiment, and through experiment and control to around and behind test to show four months performance, to reach essence confirmation, whether the result have effect to prove in training.
To sum up, this study’s core heart is developing organize effects to promote improving effect on the premise, through each improving action training and cross function teams is effective in motion and use Taguchi method’s application. The ultimate aim of this study; is expected in both costs, qualities, effects, under the success in case, improve company’s quality work, further to reach employees’ learning to promote, behavior change in positive and product harmful rate to reduce, manufacture ability to promote (and quality elevated), manufacture cost to reduce (and cost strength to descend), that can improve much effect.
Through reality training study that shows a series of training activities, in study case company training employees improve the test result in learning stratification plane, in great and excellent area occupy 80%, improve test result in behavior stratification plane, department manager observe training employees, in agree and very agree area occupy 97.1%, and result stratification plane effect improve from statistics, quality strength stratification plane：product’s bad rate from 2.8% to declined lim0, manufacture ability by a wide margin elevated, in cost stratification plane：Producing cost save total about NTD 4.34 million, and confirm comparatively the result how effect in before and after improving. Therefore, the whole improvement effect is very remarkable. Therefore, that can improve activities training indeed get better in improving effect, and reach the target in future.
