Stamping 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…
Standard 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).…
Six 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…
How 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…
Method 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…
Benefits 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…
Common 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…
What Are The Advantages Of Making Molds With 3D Printing? 1. Mold production cycle shortened 3D printing molds shorten the entire product development cycle and become the source of drive innovation. In the past, companies sometimes chose to postpone or abandon design updates for new products, given the large capital investment required to create new…
Mold Polishing Work Environment The polishing process should be carried out separately at two working locations, that is, the rough grinding processing location and the fine polishing processing location are separated, and care should be taken to clean the sand particles remaining on the surface of the workpiece in the previous process. Generally, after rough…
Matters Needing Attention During The Polishing Process Of The Mold Surface 1. When a new cavity begins to be processed, the surface of the workpiece should be inspected first, and the surface should be cleaned with kerosene so that the surface of the oilstone does not stick to dirt and the function of cutting is…
