Mold Material Selection Needs To Meet The Performance Requirements Mold manufacturing generally involves several processes such as forging, cutting, and heat treatment. In order to ensure the quality of the mold and reduce the production cost, the material should have good forgeability, machinability, hardenability, hardenability and grindability; it should also have small oxidation, decarburization sensitivity…
DetailsFactors Affecting The Accuracy Of Mold Processing The quality of the machine depends on the processing quality of the part and the assembly quality of the machine. The machining quality of the part includes the machining accuracy and surface quality of the part. The machining precision refers to the actual geometric parameters (size, shape and…
DetailsAutomotive Plastic Mold Classification There are many methods for classifying automotive plastic molds. According to the different methods of plastic parts molding, they can be divided into the following categories. 1.Injection mold The injection mold is also called an injection mold. The molding process of such a mold is characterized in that the plastic raw…
DetailsStamping Die Damage Reasons 1. Check whether the manufacturing material of the stamping die is suitable, and whether the corresponding hot-buried process is reasonable. The heat treatment process of the stamping die material has a great influence on it. If the quenching temperature of the stamping die is too high, the quenching method and time…
DetailsStandard Stamping Die Punching Method The standard stamping die punch mainly includes five kinds of cutting edge cross-section shapes, wherein the circular cutting edge cross-sectional shape is relatively simple and has only one diameter parameter. The other types of cutting edge cross-sections involve multiple parameters such as length (P), width (W), and rounded corner (R).…
DetailsSix Major Reasons For Screw Breakage In Injection Molding Machines The six common reasons for screw breakage in injection molding machines are as follows: (1) The quality of the screw of the injection molding machine itself is poor. (2) The screw length to diameter ratio is too large. (3) There is a problem with the…
DetailsHow To Judge The Quality Of The Extrusion Die The use of extrusion dies is also very common. If you do not notice the quality of the extrusion when you use it, it will seriously affect the normal use of the extrusion dies. In order to make the molds use well, the following judgments are…
DetailsMethod For Solving The Problem Of Tensile Mold Strain Solving the problem of strain in the mold and workpiece forming process should be based on the basic principle of reducing adhesive wear, and changing the nature of the contact pair as a starting point. Hereinafter, the three sides of the pair of contact pairs are…
DetailsBenefits Of Multi-Layer Hot Runner Mold ompared to conventional single-sided injection molds, the use of stacked hot runner molds allows the plastic melt to be evenly distributed into two separate parting surfaces, thereby more than doubling the throughput of the injection molding machine. Double the production of parts The stacked hot runner mold technology does…
DetailsCommon Defects And Correction Methods For Aluminum Castings 1. Under-casting (under-filling, unclear outline, corner defects) Reason for formation: (1) The fluidity of the aluminum liquid is not strong, the gas content in the liquid is high, and the scale is large. (2) The cause of the casting system is bad. The inner gate section is…
