The principle and application of deep cryogenic treatment of molds.
Post-processing of molds, including grinding and electrical machining, generates localized high heat on the processed surface, which can lead to changes in the surface structure of the mold. The formation of primary martensite on the surface increases the brittleness of the mold surface and pits, reducing the mold's fatigue resistance while also decreasing its wear resistance. Excessive grinding and discharge can also lead to surface cracks.

Current status of the mold industry development
Molds, known as the "mother of industry," are processing tools that process raw materials, giving them complete configurations and precise dimensions. They are mainly used for the efficient mass production of related components in industrial products. The market size of the domestic mold industry: plastic molds account for a significant proportion of the total mold sales in the country, approximately 45%; stamping molds account for about 37%; casting molds account for about 9%; and other types of molds make up about 9%.

What is the function of a mold?
Molds are various molds and tools used in industrial production to obtain the desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to manufacture molds made up of various parts, while other molds consist of different parts. It mainly achieves the shaping of items through changes in the physical state of the molding materials. It has long been referred to as the 'mother of industry'.

Classification of mold materials
Molds are important process equipment for material forming and processing, and are one of the essential foundations for industrial production in sectors such as machinery, electronics, light industry, and national defense. The use of molds can achieve less or no cutting processing, thereby improving production efficiency and reducing costs. Due to the characteristics of high yield, high quality, and low consumption in mold forming, it enhances production efficiency and lowers costs. Mold forming is widely applied because of its high output, high quality, and low consumption. Among them, 60% to 70% of the forming processing for electromechanical products like airplanes, cars, and tractors; 80% to 90% for household appliances and plastic products.

Classification of molds and key design points
There are many types of molds, which can be classified based on the processing objects and processing techniques as follows: 1. Molds for processing metals. 2. Molds for processing non-metals and powder metallurgy. This includes plastic molds (such as two-color molds, compression molds, and extrusion molds), rubber molds, and powder metallurgy molds. Based on structural characteristics, molds can also be divided into flat punching molds and cavity molds with space. Molds are generally produced in single pieces or small batches. According to the different materials being formed, they can be categorized into hardware molds, plastic molds, and special molds.

Methods for selecting a cold-rolled pipe core rod manufacturer
Currently, the methods commonly used to select manufacturers of cold-rolled tube core rods are mainly as follows: 1. Intuitive Judgment Method The intuitive judgment method refers to a way of selecting manufacturers of cold-rolled tube core rods through investigation, soliciting opinions, comprehensive analysis, and judgment. It is a method with strong subjectivity, mainly listening to and adopting the opinions of experienced procurement personnel or directly making judgments based on the experience of procurement staff. The quality of this method depends on whether the information about the cold-rolled tube core rod manufacturers is accurate and complete, as well as the analytical judgment ability and experience of the decision-makers. This method is simple and quick to operate but lacks scientific rigor.

How to choose a manufacturer of cold-rolled pipe core rods?
1. Check the qualifications of the cold-rolled pipe core rod manufacturer When choosing a cold-rolled pipe core rod manufacturer, you should check whether they have a business license, production permit, and relevant certifications. There are many manufacturers who have entered the market halfway and lack the necessary qualifications, supervision, and related certifications. This makes it difficult to ensure that the products and quality produced by the cold-rolled pipe core rod manufacturers meet standards. 2. Investigate the strength of the cold-rolled pipe core rod manufacturer External promotions can be falsely exaggerated, while on-site inspections serve as a "mirror" that allows us to better understand the manufacturer's scale, production processing capabilities, workshop equipment, production technology, and research and development capabilities.
