How to detect the quality of automobile stamping parts

In the stamping parts of automobile, some parts are directly made into auto parts after stamping, and the other parts are processed by welding, mechanical processing, or paint after stamping. Xiaobian tells you that for automobile stamping parts to install automobile reliability, we need to check the quality of automotive stamping parts.
Quality inspection of automobile stamping parts:
1, material inspection: materials play a key role in automobile stamping parts, so we need to check the quality of materials, mainly materials receiving inspection and material cleaning before, after inspection and inspection before the production of materials.
2, the first 1 sequence parts check: the first part of the car stamping parts directly related to the quality of the whole batch, so we must strictly check the first piece, mainly check whether the parts are marked, cracking, wrinkles, deformation and other bad phenomena.
Automobile axle stamping parts:
3, online partition inspection: the 100% inspection of automotive stamping parts is achieved through partitioned inspection, including visual and tools.
4, plate thinning rate detection: using the plate thickness measuring instrument to detect the cracking parts of the parts and the cracked parts of the manufactured parts analyzed by the CAE, the early warning of the dangerous parts of the parts which are easy to crack can be detected in advance.
5, part precision detection: using tools to measure the precision of the parts (the first piece) in full size, it can early warning to the parts with higher qualified rate, so as to avoid the size accuracy of the whole vehicle.
6, part two check: the two inspection after the production of easy cracking parts can avoid the outflow of defective products due to the undetected preorder inspection.
7, the first part, middleware and tail part extraction check: using the first part, middleware and trailing parts extraction check can achieve better quality control.

8, the whole basket inspection: the whole basket after the basket to carry on the quality confirmation, can avoid due to the improper use of personnel basket and work position equipment caused by the outflow of bad parts.
9, defective products hand repair: defective products hand repair is to check the whole basket and two times after the product is repaired. The purpose is to repair defects in quality control projects, avoid outflow of defective products and reduce scrap losses.
10, the inspection of the products out of the warehouse is the last pass of the quality control of the parts, and the outflow of the defective products can be effectively avoided through the re confirmation of the outgoing inspection.
The above ten points are related to the quality inspection method of automotive stamping parts. Of course, here in Dongguan punching small editor to remind you, do not in order to catch up with efficiency, so that the quality of the test behind the brain, so it is likely to lead to car stamping parts, and lead to the safety of the car.

Precise metal processing flow, look at these points.

The hardware stamping parts have been widely used in life. We can produce items that we need daily by using precision metal stamping parts. Many people know that precision metal stamping parts, but do not know the processing flow of precision metal stamping parts. This is not the Dongguan hardware stamping Xiaobian to introduce the process of precision metal processing for you.
The process of precision hardware processing:
1. The process route of precision hardware processing has great uncertainty, a kind of parts or products can have many kinds of craft, and the machine equipment and fixture of the production process are many kinds.
2, there are many parts needed, and the workshop site often needs to fill in a large number of documents and see the "one word type". For process management, a large number of process transfer sheets should be filled in.
3, product parts are usually made by combining self-made and outsourcing processing. For example, special processes such as electroplating, sandblasting, oxidation, screen printing, radium carving and other special processes will be processed by external manufacturers.
4. Because of the scattered processing of the hardware manufacturing enterprises, the quality and productivity of the products depend greatly on the technical level of the workers, and the degree of automation is mainly in the unit level, such as CNC machine tools and flexible manufacturing systems.
The above four points are the basic process of hardware stamping. I think you know something about it. Dongguan hardware stamping Xiaobian tells you that the production process must pay attention to details, reduce unnecessary damage.
