At present, all walks of life are developing rapidly, the market demand for precision aluminum alloy parts is also increasing, and the shape and structure of products are becoming more and more complex. Increasingly demanding. Then, quality control has become the first consideration of CNC processing manufacturers.
Regarding quality control, 2F Prototypes does this.
First, the selection of raw materials. The characteristics and functions of different materials are different. The function of parts is guaranteed, and the raw materials purchased must meet the requirements of customers. 2F Prototypes selects the most suitable aluminum alloy material for processing based on the 3D drawings, samples and requirements provided by customers.
The second is the aluminum alloy processing technology. It is processed by the advanced CNC machining center in the current machining industry, which is characterized by small error in product processing, high precision, fast product forming speed, and can process precision parts with complex shapes and structures. After the aluminum alloy is processed, it is polished and polished by the manual department to make the surface of the product bright and round.
Finally, quality inspection. The surface treatment of the product is completed manually and after the initial inspection, it is handed over to the 2F Prototypes quality inspection department to inspect the overall product quality. This step consists of three steps: size, weight, and appearance of aluminum alloy parts. After the quality inspection is completed, they are packaged and mailed to customers. Ensure that the products delivered to customers meet the requirements and even exceed customer expectations.
