Common market requirements for aluminum parts processing and how to select quality standards for processing raw materials

With the development of the times, people will invent various products to meet the needs of users, because only in this way can there be good market sales and people will like it. The same is true for the production of aluminum parts. What common market needs can it meet for aluminum parts processing? Let's take a look.

In life, we use a variety of parts, that is, when using many machines, we use many parts. But sometimes our parts are not accurate enough, so we can buy aluminum parts for production at this time. Why? Because in fact, the production of aluminum parts can be equivalent to many ordinary parts. Without these parts, many of our machines would be useless.

But we often reoccur, which is to say, we sometimes find that our aluminum machining production is not good enough. Take a car as an example. If our car breaks down, we will buy parts and then buy cnc parts. When we got back, we found that we still couldn't meet our car's requirements. At this point, you need to deal with things like aluminum production, i.e. processing the aluminum production that you purchased, and then meet the requirements of your machine. A very simple thing.

The quality of aluminum processing products means that the qualified products provided need to fully reasonably meet the service performance and user requirements of the products. That is to say, from the selection of raw materials and accessories, the careful design of process equipment and molds, the careful preparation and implementation of aluminum processing production methods and process specifications, and the accurate inspection of products during the production process, the technical standards or technical quality are officially determined by both parties. sign. The requirements of the indicators can be met in all aspects (including material composition, appearance and internal quality, organization and performance, accuracy of size and shape, etc.). Like most other products, the quality indicators of the raw materials selected for processing aluminum parts should include the following:

1. Chemical composition. Including the main constituent elements of the alloy and their proportions, the amount of added trace elements and impurity elements, should meet the requirements of relevant technical standards or technical agreements.

2. Internal organization. Mainly include particle size, morphology and distribution; number, scale and distribution of the second stage; number, size and distribution of metallic and non-metallic inclusions; porosity and gas content and distribution; internal cracks and other discontinuous defects; Meet the requirements of technical standards or technical agreements.

3. Internal and external surface quality. According to the requirements of the technical standard, the inner and outer surfaces should be smooth, smooth, harmonious in color, to a certain degree of smoothness, free from cracks, scratches, scratches and corrosion marks, no air bubbles, pores, black and white spots, pits and waves.

4. Performance. According to technical standards or user requirements, reasonable physical and chemical properties, corrosion resistance, mechanical properties, processing properties or special performance indicators should be achieved.

5. Dimensional tolerance and shape and position accuracy. Dimensional tolerances including cross-section and product shape and positional accuracy should meet technical standards and usage requirements.
