Do you know all about the failure of wire drawing dies?
After installation and debugging of the wire drawing mold, qualified workpiece can be normally produced, and this process is called mold service. In general, we always hope that the mold can have a sufficiently long service life to meet the actual needs of production.

Do you know the relationship between the quality of the wire drawing die and the core material?
The quality of wire drawing dies is closely related to the core material. In fact, for wire drawing dies, all their quality is also closely related to the production materials used in production. If you are in production, if you do not meet the requirements for production materials, it will also reduce the quality of the entire product. If users of wire production introduce this mold, naturally, they cannot allow themselves to improve the efficiency and quality of wire products.
Introduction to Alloy Wire Drawing Dies How do mold manufacturers prevent strain during use?
It can be said that friends who make molds for stretch products are very common, but designing such mold manufacturers takes some time. After all, there may be some differences between on-site mold testing and mold design. In fact, it is common for this type of product to experience strain during use, so how should we prevent strain? Let's follow the alloy wire drawing die to learn more! 1. Materials Some materials with special requirements require special treatment, such as phosphating, spraying, and other methods. This is to produce a thin film on the surface of the mold manufacturer to prevent or reduce strain problems. This method is highly effective, but it costs a lot of money, so it is not used much. 2. Material structure The cost of using protective films on products is very high, so we switched to plastic films. This is a good way to obtain a layer of PVC film. Some small products can be solved with lubricants. However, this film preparation method is only suitable for mass production and small batch production, as each product must be made of thin films, which will increase a lot of time and waste. 3. Structure When I say this, I cannot help but say that the previous methods may not completely solve the problem. A better method is to immediately change the material and hardness of the concave and convex mold, or titanium plating and polishing the product if there is a strain problem. To essentially change the contact surface between the product material and the concave and convex mold to eliminate the problem of strain. The above is an introduction to alloy wire drawing molds on how to prevent strain during the use of the mold. I hope it can help everyone.
How to select a mold base and insert for a wire drawing die?
Determination of mold base and insert dimensions The size of the wire drawing die mainly depends on the size and structure of the plastic product. For molds, the more compact the structure, the better, while ensuring sufficient strength. The size of the insert can be determined based on the external dimensions of the product and the structure of the product itself. After determining the size of the insert, you can roughly determine the size of the mold frame. 2. Selection of insert material The performance of die insert materials for wire drawing molds mainly includes four aspects: hardness, wear resistance, strength and toughness, and corrosion resistance. The selection of mold insert materials mainly depends on the volume and type of plastic product. These products are ordinary plastics, such as ABS, PP, PC, and other plastics. P20 type and other types of pre quenched and tempered steel are commonly used. If the product batch is large, quenched and tempered steel, such as H13 type, should be used. 3. Determine the height of the square iron The height of the square iron should ensure sufficient ejection stroke, and then leave a certain margin to ensure that when the ejector is fully ejected, the fixed plate of the ejection pin will not touch the movable template or the movable mold support plate. 4. Determination of the overall structure of the mold base After the basic selection of the mold base, the overall structure of the frame should be checked to see if the determined mold base is suitable for the selected or customer specified injection molding machine, including the size, thickness, large mold opening stroke, ejection method, and ejection stroke of the mold base. The above is an introduction to the selection of mold bases and inserts for wire drawing dies. I hope you can understand.
Introduction to Basic Knowledge of Wire Drawing Dies
The reason for the ring groove in the drawing die is that the resistance of the metal wire entering the die hole when the cross section changes and the periodic pressure caused by the vibration of the metal wire during drawing lead to the fatigue failure of the die.
Application and main application of wire drawing die in some industries
Drawing dies have a wide range of applications, such as advanced wire for electronic equipment, radar, television, appearance, and aerospace, as well as commonly used tungsten, molybdenum, stainless steel, wire and cable, and various alloys. For silk, the diamond drawing die uses natural diamond as the material, which has strong wear resistance, rather than extremely high wear resistance. The production process of wire drawing dies includes multiple processes such as molding, drawing, and turning.
