Improving quality and increasing efficiency need the support of Guangzhou Six Sigma Green Belt Training. Through two cases, I tell you that in a factory that processes small fans, there is a case of poor assembly of fan products. This assembly is to assemble the fan blades with the rotor. Product defects are scratches after assembly. The original processing method is: firstly, the blades and rotors are assembled together; secondly, the assembled products are heated and riveted by plastic melt to achieve the purpose of connection and fixation. And both processes have scratches. The first idea is to repair the fixture in each process to reduce scratches. The second idea is to change the processing mode, combine the two processes into one, and reduce the number of clamping to reduce scratches. The project team chose the latter, and realized one-time assembly and fusion by designing new fixtures, which reduced one working procedure and scratch defects. It also shortens the processing cycle, improves the production efficiency, and the factory benefits greatly.

In a computer parts processing factory, there is a case of improving productivity: one of the key processes is to process aluminum alloy parts with numerical control equipment. Due to the expansion of production scale, although the factory has purchased hundreds of CNC machine tools, the CNC machining capacity is still insufficient. In a six-sigma project, by changing the clamping mode and selecting the appropriate cutting tools and processing parameters, it is necessary to stop loading one piece, and then two pieces can be processed at a time, so that the productivity is improved by 30% (it takes a little more time to process two pieces at a time). Therefore, the company can buy dozens of CNC machining centers less, and the income is huge. We can see many similar projects. The original heat treatment furnace can only heat one piece, and two pieces can be heated through process research. And so on, through process research to improve production capacity and reduce the use of special equipment to reduce the company's processing costs.

The thinking point of Guangzhou Six 6sigma Green Belt Training is to analyze and challenge the existing processing methods and technologies in order to improve the quality and efficiency. Any factory must have some main products, and these products must have some special processing methods and technical requirements. Improving these processing methods and improving product quality and processing efficiency will greatly improve the competitiveness of the company. In addition, some special equipment is usually used to complete these products, which is often the bottleneck of processing capacity. The improvement of the process avoids the periodic influence of the product. Therefore, it is of great significance to pay attention to the main processing technology and find a breakthrough, which is a good starting point for options.
