How does Anhui Cummins view the control of quality? Intertwined, happy in it

The automotive industry has been rumored to be saying that quality is not just tested, it is also designed, produced, and procured.

As the quality director of Anhui Cummins Power Co., Ltd. (hereinafter referred to as Ankang), there is a lot of positions in this kind of link that can't make a mistake. Jiang Huawei gives the impression that he is happy. His interpretation of quality is a series of technical terms, as well as a very interesting statement: the value of the quality department is to let users feel the quality of the surprise.

For Ankang, the surprise has already occurred: the early failure failure rate has dropped drastically, and the thousand failure rate is controlled within 1‰.

Process assurance fully adopts Cummins quality standards

In the first year of the joint venture, Ankang set high demands on its quality. Surprise comes from the Cummins quality management system and the full use of Cummins quality standards.

Jiang Huawei told reporters that because quality penetrated into the whole process of products from scratch, Ankang learned from the Cummins approach and established the PQC (Product Quality Committee) management process to organize teams including technology, quality, manufacturing, procurement, and service. Quality issues are analyzed in detail to determine improvement needs.

Drawing on Cummins, it is also reflected in the establishment of a sound quality information collection and management system. “Only the information is accurate, only to know the current problems and the level of the situation.” He further said that in the manufacturing process, Ankang introduced Cummins safety management process, manufacturing process quality verification, and understanding the status of each component concerned. The parameters (such as crankshaft torque and fit clearance) are analyzed and recorded. “The judging panel will review the records and report to the company management after signing that there is no problem.”

The benefits of doing so are obvious. As a newly established company, launching products to achieve sales is the core task. If there is no process guarantee, it is easy to rush into the market due to the situation, causing the problem engine to flow to the market, which will bring irreversible negative impact. “With process guarantees, every component is confirmed, and the chances of failure are low,” he said.

Manufacturing strict internal and external repairs to create the "Ankang produced" label

Manufacturing is an important part of quality management, and it is also an aspect that Ankang attaches great importance to. “This can be subdivided into two situations: internal and external.” Jiang Huawei told reporters that the internal and external software and hardware upgrades improve product quality. “For example, through hardware upgrades, our process capability index is greater than 1.67. : In industrial production, when the process capability index is between 1.67 and 2, it means 'the test can be appropriately relaxed'; the index is 1.33-1.67, which means 'continue to keep')."

Externally, it refers to supply chain management. In this respect, the health of the Cummins standard has changed a lot. Ankang will evaluate the supplier's technical and quality control capabilities based on the procurement input list, increase cooperation with suppliers that best meet the needs of users, and adjust to suppliers that cannot meet the requirements; especially for problems that have occurred in user use. Key inspections of parts with early failure problems. In the early stages of the new product, Ankang will require the supplier to confirm each batch of products, and will also send procurement engineers to the site for confirmation. “After confirming that the requirements are fully met, the parts are allowed to be sent to Ankang; without confirmation report, even if the supplier delivers the goods according to the order, our warehouse will not receive it.” He further introduced that “the country’s six-stage warehousing inspection will More stringent, such as the important indicator of cleanliness, we will check the fuel pipeline, oil pipeline and airway."

Post-sale iteration to form a discovery-solution-prevention closed loop

In the usual sense, after the quality of the manufacturing process is controlled, the task of the quality department is completed. However, the chain of the quality department of Ankang is longer – extending to the after-sales service.

The quality problems of this link can be divided into three categories. The first type is the early failure failure, which is the problem that occurs during the initial use of the user. We control it as a key KPI indicator. The Quality and Service Department will jointly analyze each of the early failure failures to find out which part of the design, manufacturing, and parts are involved. For example, if a 3,000-kilometer failure occurs in a service order, the service personnel will go to the site to confirm. If the problem cannot be confirmed, the replaced parts will be shipped back to the company in time, and the quality and technical personnel will analyze the reasons.

The second category is the failure after long-term operation, and Ankang will solve the problem in a large number of cases.

The third category is the problems that occur in the assembly and commissioning of Ankang's OEM customers. As long as it is an Ankang problem, each case will be included in the zero-kilometer failure for improvement.

Among these quality problems, there is a special "quality problem", which is the fault caused by improper use of the user. "For example, if the limit of the urea is not up to standard, it is more important to remind the user than to distinguish the responsible person. We will put the problem into a prominent position and the service staff will explain the user. Jiang Huawei said that Ankang has compiled a detailed inspection manual and service operation procedures to inform the processing steps of the service station.

In the face of cumbersome work, using "fine" to change the same, this is the secret of the quality of Ankang.

uPVC window corner-cleaning machine is specially used to clean weld seams on uPVC windows and doors, and it is one of major uPVC window machines. After uPVC profiles are heated, melted, and welded to form window frames or sashes, of which there will be weld seams (weld beadings) on the corners. Cleaning these weld seams with a corner-cleaning machine will not only ensure the beautiful outfit of uPVC windows, but guarantees the weld strength and increases the productivity of uPVC windows and doors.
