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…
Ten Surface Treatment Technologies For Forging Dies The treatment technology that uses modern technology to change the surface, subsurface composition, structure and properties of the forged mold is called surface modification technology, and mainly includes the following ten categories: 1.Electrochemical transformation The technique of forming an oxide film on the surface of a part in…
How To Judge Whether The Mold Is Invalid? Mold failure refers to the loss of normal working ability of the mold, and refers to the phenomenon that the working part of the mold is seriously worn or damaged and cannot be re-commissioned by the general repair method (sharpening, polishing). Die life refers to the number…
Factors Affecting The Polishability Of The Mold Surface 1. Surface condition of the workpiece During the machining process, the surface layer may be damaged by heat, internal stress or other factors, and improper cutting parameters may affect the polishing effect. The surface after EDM is more difficult to grind than the surface after machining or…
