In this increasingly competitive era, the CNC machining industry is becoming more complex. We will analyze the current state of the CNC machining sector from four key dimensions: market landscape, technological applications, industry challenges, and regional development:

Investment casting, also known as lost-wax casting, is a high-precision manufacturing process particularly suited for producing metal parts with complex geometries, tight dimensional tolerances, and smooth surface finishes. This method excels in creating intricate shapes that are difficult or impossible to achieve with other processes—such as hollow structures, multi-curved surfaces, and fine details. Depending on the part size and design, dimensional tolerances can reach ±0.1mm, significantly reducing machining allowances or even eliminating the need for post-processing. 

Both investment casting and sand casting fall under the umbrella of casting processes; however, they exhibit notable differences in their technological process, scope of application, quality of castings, and cost implications. In the ensuing discourse, we shall dissect the distinctions between them across these several dimensions, with the aspiration that this analysis will aid in the judicious selection of the appropriate manufacturing technique.

With the rapid advancement of technology and the swift progress of society, the field of precision machining is bound to undergo significant transformations to adapt to societal development. Below, we analyze potential future changes from several perspectives:

CNC machining is a highly precise and automated manufacturing process that is suitable for products of various materials and complex shapes. The CNC machining we usually talk about includes CNC milling, CNC turning, CNC grinding, CNC wire cutting, and CNC compound machining, etc. Some products can be completed using the above single process, while some require the above multiple processes to complete, which depends on the product structure. So which products or parts are suitable for CNC machining? We classify and analyze from the following points:

In investment casting production, casting defects are inevitable due to the long and complicated process. If casting defects occur during production, it will not only increase production costs, but also affect production progress and delivery time. If quality accidents occur during use, it will not only cause significant economic and reputation losses to the company.

    We have recently produced a rather special precision machining parts. Due to its special requirements, it is a relatively typical part. I would like to share it with you, hoping it can give you a reference.

   The following two pictures are actual photos of the product after production. This product has the following special features. Let me analyze them with you.

With the continuous change and development of science and technology, all walks of life are also facing the situation of continuous change and development. The CNC machining industry is no exception and will continue to develop with the changes in society and the development of science and technology. We can predict that the future of the CNC machining industry will change in the following aspects:

We have just completed the production of a product. The structure of this product seems to be not difficult, but it is still difficult to produce it according to the customer's requirements. So, I would like to share this product with you.

We can see metal products in many manufacturing industries or daily necessities. How are metal products processed? In fact, metal products can be formed in many ways depending on their structures, such as stamping, powder metallurgy, forging, die-casting, precision casting, CNC machining, etc. Today I will share a metal product we produce, which includes the following processes: investment casting, CNC machining, carbonitriding heat treatment, welding and grinding, black phosphating surface treatment, etc. Please see the finished product picture below:
