Company A Diesel Part Manufacturing Process Quality Control Study

Because of the very fast about development of transportation business,marketing share of diesel engine is constantly expanding.Behind the considerable sales volume,there is a battle for the position of the major engine manufacturing companies.The position is profit,and the reputation is position.What can we do for the unbeaten reputation?The quality should be the first.Quality is not only designed,but also the quality is manufactured.The design quality needs strong professionalism,once it is finalized,it will be stable;but the manufacturing quality is just the opposite.Only the manufacturing process that is effectively controlled can ensure the stability of the quality.Since the invention of assembly line,each country has formed its own and even general process control means and control methods to obtain stable quality,such as Toyota Motor,Bosch group,which means high reputation and high sales volume,that is,high profit in the world.At present,our country is in the key stage of intelligent manufacturing transformation.It is the current trend to get rid of the style of small workshops and invest a lot of high-end equipment.These belong to the preparation of hardware.The quality control of manufacturing process is the soft power.Only by adopting appropriate control means and control methods,can we put an end to waste,maximize profits and bring vitality to the manufacturing industry This paper takes company A as the research object.Company A has a high-end position in the industry.The company has excellent historical precipitation and excellent management experience.In the manufacturing process of the engine,there are layers of quality control.At the same time,using big data and SPC process control,MSA analysis tools,it has accumulated a lot of process manufacturing data,real-time monitoring,constantly updating and improving the manufacturing process,and strictly controlling manufacturing Quality,so as to improve the product qualification rate,reduce the repair cost,put an end to seven wastes,and improve the competitiveness of the company from the perspective of cost and quality.Aiming at the cylinder head manufacturing line of company A,this paper attempts to explore the potential of quality control in the manufacturing process of diesel engine parts of company A,analyze the disassembly of the manufacturing process,find out the weak links in the process,use quality management and management tools for in-depth analysis,and get a set of effective quality control means for the manufacturing process of company A,or even get More promotion and popularization.
