Standardization: standard parts or general-purpose machinery production process control of the assembly costs, improve labor / process / materials, the implementation of the standardization of equipment, but also a great benefit. The implementation of standardized management, applied the next twenty-eight law is to take 20% of the equipment to produce 80% of the ordinary products, so that we have 80% of the cost and effort do we believe that a greater contribution to the results or the importance of superior part of the product, which is 20% quality products. the implementation of standardized, the positive significance of the cost down: as long as we retained the machinery of key agencies, standardized part of the misappropriation of emergencies or useful occasions, you can greatly improve the utilization of equipment, and will not impede the production of smooth, standardized part can always be called from other PULL thus make full use of the machine (after the topic to talk about) (N "s: _ # j: E +} 'q4 the G7 z7 \ 1 f
(2) semi-automatic: full automation is difficult to do, but the semi-automatic is really a development direction, with the forward-looking and necessity. First of all, strictly speaking, semi-automatic only the independence of Taiwan and Taiwan fixtures through a ways to join or merge together, have more control part, but also need the participation of the operator, the efficiency is much higher than the purely artificial lines in the context of gradual improvement in the labor costs, product cost control a considerable portion to be transferred to machinery, semi-automatic undoubtedly can play this important role. Furthermore, many large customers as an indicator to measure whether the supplier has sufficient strength to do their own products through the analysis, I think, more reasonable production mix, might be: 20% 40 of the artificial line of automation 40% semi-automatic. 2 of S. h + r4 U1 is u4 l8 B, (q1 \ & y% r
Humane: This is not a general topic to talk about, on the contrary, of great significance. This is not only the operator's voice, the voice of the customer, or the voice of the era of user-friendly design, may for many people, have been no stranger, but there are a few people do it? analogy, how comfortable and efficient grip products put on the machine, which is related to an example of humanity. often see a lot of machine operator operating a little bit awkward.

Standardization: standard parts or general-purpose machinery production process control of the assembly costs, improve labor / process / materials, the implementation of the standardization of equipment, but also a great benefit. The implementation of standardized management, applied the next twenty-eight law is to take 20% of the equipment to produce 80% of the ordinary products, so that we have 80% of the cost and effort do we believe that a greater contribution to the results or the importance of superior part of the product, which is 20% quality products. the implementation of standardized, the positive significance of the cost down: as long as we retained the machinery of key agencies, standardized part of the misappropriation of emergencies or useful occasions, you can greatly improve the utilization of equipment, and will not impede the production of smooth, standardized part can always be called from other PULL thus make full use of the machine (after the topic to talk about) (N "s: _ # j: E +} 'q4 the G7 z7 \ 1 f
(2) semi-automatic: full automation is difficult to do, but the semi-automatic is really a development direction, with the forward-looking and necessity. First of all, strictly speaking, semi-automatic only the independence of Taiwan and Taiwan fixtures through a ways to join or merge together, have more control part, but also need the participation of the operator, the efficiency is much higher than the purely artificial lines in the context of gradual improvement in the labor costs, product cost control a considerable portion to be transferred to machinery, semi-automatic undoubtedly can play this important role. Furthermore, many large customers as an indicator to measure whether the supplier has sufficient strength to do their own products through the analysis, I think, more reasonable production mix, might be: 20% 40 of the artificial line of automation 40% semi-automatic. 2 of S. h + r4 U1 is u4 l8 B, (q1 \ & y% r
Humane: This is not a general topic to talk about, on the contrary, of great significance.
