How to control the quality of supporting products is a difficult problem that many host manufacturers have explored. Jinan Diesel Engine Co., Ltd. implemented extended management and extended the reach of quality management to the supporting manufacturing plant, effectively solving this problem.
In order to meet the needs of rapid business development, Jichai adopted a policy of “do something for nothing†and relied on social resources to spread the non-core components of internal combustion engines to the production of external companies, free up personnel and equipment, and concentrate on the production of core components. Increased production capacity. However, with the large number of kits, how to effectively control the quality of kits has become an important issue. To this end, Jichai put forward stringent quality requirements on the parts to meet the standards of exemption, no-clean and clean packaging. In order to achieve this goal, the company has implemented a method of extending management to advance the quality management from a single factory inspection to the manufacturer, and to control the production process of the parts. First of all, from the source, carefully select the supporting manufacturers. The company has carried out an orderly integration of supporting resources. On the basis of a large number of investigations, it eliminated some of the manufacturers with poor strength and small scale, concentrated the kits on some manufacturers with strong technical strength, and encouraged these manufacturers to purchase processing centers. And other advanced equipment, expand production scale, and form a processing base. At present, Jichai has six parts production bases and 16 major professional parts production bases, which satisfy the needs of Jichai for supporting products. Second, send quality supervisors to supporting manufacturers. Jichai pulled out 5 people to be stationed in the supporting factory for a long time and monitored all the production processes of the parts. Third, implement the second party review. The company formed a two-party review team to conduct a rigorous review of the quality assurance system of the parts manufacturer and help the supporting manufacturers to improve the quality management level so as to guarantee the quality of the parts. It is reported that the qualification rate of more than 5000 kits for Jichai last year reached 99.9%, an increase of 4 percentage points over the previous year. In 2005, the number of Jichuan diesel engines increased from several hundred in previous years to more than 2,000. In the case of a significant increase in the number of production, product quality has been effectively guaranteed.
