Improvement plan for short blade size of automobile vacuum pump

During the production process of blades in the workshop, the blades are often short in size. In order to ensure the quality of the blades leaving the factory, the company’s quality assurance department will conduct 100% internal inspection, but this seriously wastes working hours.

In order to solve this situation, the injection molding workshop, mold workshop, CNC workshop and quality assurance department jointly formulated the following corresponding plan, which solved the failure items in the process, improved the product qualification rate and saved costs for the company.

1. Modify the mold cavity according to the actual size

By repairing the mold, the external dimensions of different cavities are unified, laying a stable foundation for machining positioning.

2. Improve the process dimensions of the machining process

The machining process reasonably arranges the process allowance to ensure that each process meets the conditions for mass production. It is also easier for employees to operate during the production process and the product flow is smoother.

Results:

Through the joint efforts of colleagues in the injection molding workshop, mold workshop, CNC workshop, and quality assurance department, the product flow is smooth during the entire production process of automotive vacuum pump blades, saving 15%-20% of time waste.

For an enterprise, quality is the lifeline. Every one of us at Junhua is working hard every day to further improve product quality. Only by improving product quality can we win more customers and open up a larger market!!!
