Stainless steel bottle opener

Most people now understandStainless steel precision casting, Also called investment casting or wax film forging, its processing technology is generally applicable to various castings, but this kind of small problem is often encountered during the whole forging process!
1. The hammer is stuck
Solution:
1. In the production and manufacturing, the temperature is often accurately measured to prevent the hammer head and the barrel temperature from being too high;
2. Use high-quality alloy products without residue to prevent the residue from sticking to the hammer head.
2. The injection head is stuck in the gooseneck
Solution:
When the machine and equipment are at room temperature, try to rotate the hammer head. If it fails to rotate, change the barrel and remove the hammer head. If you are willing to deal with the stuck problem quickly, the best thing is to change the pot.
3. It can’t be produced after hitting more than one hundred mold materials during punching, and it will be possible to punch again after more than ten minutes.
Check if there is any flash on the top of the material head. If the cross-section is dark gray, it indicates that the nozzle is blocked. The temperature of the nozzle can be increased appropriately, and the time to leave the nozzle is reduced by 0.1 to 0.2 seconds, and the fixed mold cooling cycle The water is slightly off.
Fourth, aluminum die-casting thick-walled products are the easiest to crack
Solution:
When this problem occurs, it will be that the raw materials are not good, the abrasive tools are not well set up, or the main parameters of the processing technology are not well selected. Try to manipulate the proportion of waste not to exceed 30%, and the mold retention time is not suitable for too long. The wall thickness of mm is 3s up and down, and the injection court cannot be long, usually 0.5-2s.
5. The raw materials are hard, and the CNC blades are easy to damage
Solution:
It is prepared with the original raw materials, no need to regenerate the raw materials, and the spar cutter head specially produced and manufactured for tungsten steel is selected.
Six, the castings are caused by lines after anodizing
Solution:
Uneven spray paint and injection oil, improper high-speed conversion parts, or excessive water content of copper ion in the air oxidation tank cause problems in the texture, so that the spray paint and injection oil can be spread evenly, not collected in the part, or set well High-speed conversion position to reduce under-casting conditions.
Seven, die-casting mold sticky material
Solution:
1. Check if the preparation of the release agent is abnormal, try to disassemble the release agent;
2. Adjust the surface layer of the spray paint to carry out polishing, and carefully polish and polish the abrasive tools that have been nitrided to avoid destroying the nitriding layer on the surface, resulting in a situation that becomes more and more sticky;
3. Improve the design and structure of the pouring control system to prevent the aluminum alloy liquid from continuously corroding the cavity wall or core;
6. Modification of the refrigeration system of abrasive tools;
5. Adjust the main parameters of the die-casting process, moderately reduce the injection rate, and reduce the two-speed stroke arrangement.
