Factors Affecting The Service Life Of Cold Stamping Dies 1.Break Cold stamping die convex, concave mold in the course of use, sudden appearance of breakage, breakage and cracks. Since the convex and concave molds of the mold are the parts that the mold is subjected to the maximum punching force during the stamping work, the…
Structural Factors To Be Considered In Plastic Mold Design 1. Parting surface, that is, the contact surface where the die and the punch cooperate with each other when the mold is closed. The choice of its position and form is influenced by factors such as product shape and appearance, wall thickness, forming method, post-processing process,…
Mold Modular Design Method Shortening the design cycle and improving design quality is one of the keys to shortening the entire mold development cycle. The modular design is to use the similarity in structure and function of the product components to achieve standardization and combination of products. A large number of practices have shown that…
Factors Affecting The Metamorphic Layer Of The Middle Wire Cutting 1. Metallographic structure and elemental composition of the workpiece material Due to the discharge of the electric spark, the metallographic structure of the surface layer of the workpiece material changes significantly, forming a discontinuous, uneven thickness of the metamorphic layer. It is related to the…
What Is Vacuum Casting? Vacuum casting is a process that uses a ventilated mold. The molten metal flows into the mold by air pressure and then removes the air to form a vacuum. This casting method is mainly used for small parts or jewelry with intricate details. It is a physical modeling method. The vacuum…
What Kinds Of Vacuum Casting Are There? Vacuum casting can be roughly divided into three types: vacuum suction casting, vacuum low pressure casting, and vacuum differential pressure casting. 1.Vacuum suction casting Vacuum suction molding refers to placing the mold in a closed container and extracting the air inside the mold to cause a certain negative…
Selection Principle Of Die-Casting Mold Materials In all the molds, the order of the amount of the mold is a plastic mold, a cold stamping mold, a casting mold, a forging mold, and the like. However, due to incorrect material selection, improper process or improper operation, low temperature strength and toughness, poor high temperature wear…
Mold Overall Toughening Treatment The die steel is widely used. The conventional heat treatment process is quenched at 1050 °C ~ 1100 °C, tempered at 550 °C ~ 620 °C, and the hardness is generally 45 HRC ~ 50 HRC. The early fracture phenomenon often occurs in use, and the die life is often low.…
Mold Surface Strengthening Treatment In recent years, with the development of industry, the requirements for product quality have become increasingly strict, and the requirements for molds have become higher and higher. In particular, precision die-casting molds require a high degree of mechanical properties, and require a small amount of deformation, which is basically no longer…
What Is The Middle Wire Cutting Technology? The middle wire cutting process is a processing method that utilizes the thermal effect of the instantaneous discharge energy to melt and evaporate the workpiece material to meet the dimensional requirements. Since the wire-cut working fluid mostly uses a dielectric liquid, it is accompanied by a certain electrolysis…
