What affects the beauty of metal powder injection molding
Whether there is a certain standard for the selection of metal powder injection molding parts is certain. The standard generally refers to whether its quality is qualified and whether it can withstand long-time action. If it is a part with poor quality, the time it can use will be much shorter than that of a part with good quality, and it will also delay a lot of things. Now let's talk about the method of burr removal of metal powder injection molding parts
Burr removal method of metal powder injection molding parts:
1. Electrolytic deburring
This deburring method is achieved by dissolving the anode with electric energy and chemical energy. The turbine flowmeter part is connected with the positive pole of the DC film as the anode, and the forming tool is connected with the negative pole of the DC power supply as the cathode. A gap is maintained between the two poles to allow the electrolyte to circulate.
2. Chemical deburring
Put the sorted parts into the metal solution, and the metal on the surface of the parts will be transferred to the solution in the form of ions. These ions will adhere to the surface of the part to form a film with high resistance and low conductivity to protect the workpiece from corrosion. Since the burr is higher than the surface, the burr can be removed by chemical action.
3. High temperature deburring
First put the parts to be deburred into the tight sealing chamber, and then send them into the hydrogen and oxygen mixed gas with a certain pressure. Ignite the mixed gas to explode and release heat, so as to burn the burrs of the parts without damaging the parts.
4. Roll grinding deburring
Put the parts and abrasives into the closed drum. During the rotation of the drum, the dynamic torque sensor, parts and abrasives grind together to remove burrs. Abrasives can be quartz sand, sawdust, alumina, ceramics, metal rings and so on.
These articles not only have high precision, but also have good performance, and are suitable for mass production of small precision and complex metal parts. However, sometimes there are burrs on the surface of parts, which will affect the beauty of use, which needs to be removed by reasonable methods.
