Quality Concept

Dana has repeatedly stressed to enhance the team in the whole process of quality management concept。Different concepts led to different behavior。Only by constantly improving the quality of the whole team concept，Get people to focus on the details of the work，And in all aspects of quality control。In Dana，As we all know，Quality is the fundamental survival and development of Dana，And Dana's senior management must have a high quality concept。

QC

Dana has established its own perfect production and management system。Each process has a strict quality control management。We try to avoid errors，Error and ends the process extends to the next。

1) Product and mold design checks

Whether Dana design or customers design，We will conduct a comprehensive analysis and testing，The molding process feasibility，Feasible mold structure and，All plastic parts and the like matching of。It avoids mold modification，Waste and other unnecessary mold repair work，This is caused by a design fault。We believe we have spent over 10 minutes on the design，A month may reduce production。

2) Procurement of raw materials inspection

Parts procurement strict inspection process and time control，Parts standardization，Dimensional accuracy，Mold material hardness and material defects detection。

3) Processing quality control

Precise size，The paper size and tolerance limit control requirements，Self-test for each tooling spare parts。Only by checking，Spare parts can be delivered the next working step。Impermissible previous work flows error processing step。

Quality Inspection

1) Mold mounting quality inspection

Conduct a comprehensive inspection of the mold，Ensure structural integrity and standardization of spare parts。Project managers and quality control personnel should participate according to the standard mold test，To ensure product quality。If errors are found，You can promptly correct the error。It also prevents errors。Moreover，We will also mold cooling system，Hydraulic system oil passage and the mold hot runner system independent standardized test。

2) Acceptance inspection sample size and dimensions of the mold

QC department should conduct product testing at 24 hours post mold testing and submit the test report。The report should include product size，Exterior，Full range of testing and analysis techniques and physical parameters of the injection。We use different testing standards and tools for different products。With our equipment，Measuring and test equipment continue to improve，Our product testing more professional。

3) Acceptance inspection test mold

to some extent，Our tests are designed to find mold mold quality problems，Instead of solving the problem。therefore，We have many steps in the mold test，Including dry run，High pressure bearing，High speed injection mold injection time and the necessary checks。

4) Mold delivery inspection

According to the order file，Customer requirements and company standards，We will die rigorous testing and acceptance。These documents should be reported along with other inspection records and recorded before delivery。
