Metal products include the manufacture of structural metal products, the manufacture of metal tools, the manufacture of containers and metal packaging containers, the manufacture of stainless steel and similar household metal products, etc. With the progress of society and the development of science and technology, metal products have been more and more widely used in various fields of industry, agriculture and people's life, creating more and more value for the society.
What is the craftsmanship of metal products? Let's analyze it together.
Metalworking is divided into various manual operations. Let me analyze the different types of processing in detail. And what cost and craftsmanship do they require?
What about the casting part of metal products? Let's analyze it together.
Casting: refers to the metal heating and melting and pouring into the mold. It is suitable for machining parts with complex shapes.
What is the classification of metal products? Let's analyze it together.
Sand casting: Low cost, small batch size, can machine complex shapes, but may require many post-processing processes.
Investment casting/wax casting: This processing method has high continuity and accuracy, and can also be used to machine complex shapes. On the premise of relatively low processing cost, the surface effect can be achieved, which is suitable for mass production.
Main method: used for machining complex shapes with high error. Due to the characteristics of the process itself, no post-processing is required after the product is formed, but the advantage of low cost can be shown only in the case of mass production.
Die casting method: The processing cost is high, and the cost is reasonable only in mass production. But the cost of the final product is relatively low and the error is relatively high. Can be used to produce thin-walled parts.
Rotary casting method: It is an ideal method for machining small parts and is generally used in the manufacture of accessories. Using models can reduce machining costs.
Directional solidification: A very strong superalloy with good fatigue resistance can be produced, injected into a mold, and then subjected to a tightly controlled heating and cooling process to eliminate small imperfections.
The metal products industry has also encountered many difficulties in the development process, such as single technology, low technical level, lack of equipment, lack of manpower, etc., which limit the development of the metal products industry. To this end, we can improve the technical level of enterprises, introduce advanced technology and equipment, cultivate applied talents, etc., to improve the development of China's metal products industry.
