Development Status Of 3D Printing Materials 3D printing technology, also known as “rapid forming technology” or “additive manufacturing technology”, is based on digital model files, using powdered metal or plastic bonding materials to build objects by layer-by-layer stacking technology. At present, there are two main factors that restrict the development of 3D printing technology: printing…
DetailsSolutions For Poor Gloss On The Surface Of Products Low gloss (LowGloss) means that the surface is dark and dull, and the transparency of the transparent product is low, which causes many reasons for poor gloss. Other injection defects are also causes of poor gloss. 1.Mold failure Since the surface of the plastic part is…
DetailsPrevent Heat Treatment Deformation Of Precision Molds 1. Fair selection of materials. For precision and complex molds, the micro-deformed die steel with good material quality (such as air-quenched steel) should be selected, and the die steel with severe carbide segregation should be cast and carried out, and the solution steel can be solid solution and…
DetailsFactors 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…
DetailsStructural 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,…
DetailsMold 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…
DetailsFactors 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…
DetailsWhat 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…
DetailsWhat 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…
DetailsSelection 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…
