What changes will occur in the Dry Powder Pressing Mold the powder
Under normal circumstances, the Dry Powder Pressing Mold brittle cutting effect, in fact, much better than plastic, and can more easily meet the relevant processing requirements, but for the same material, in the metallographic structure, if it is smaller Of the words, then the better, this point in the industry are more recognized.
First, Dry Powder Pressing Mold In the forging equipment, if it is based on the weight of the forging classification, then it is best to use tonnage larger mold or equipment, and in forging before the use of hammer or hammer drill on the mold Preheating in advance to ensure the good operation of the production process.
Second, the Dry Powder Pressing Mold in the preparation of the blank powder, blank in the cutting time, it is best to carry out cold saw, and according to the different requirements of Dry Powder Pressing Mold, in the choice of raw materials, should be in accordance with the level to choose, different Of the material selection of different molds, so that the processing will be more accurate.
Third, the dry powder to suppress the mold blank heating, the blank when the heating, it is best to slow to prevent the rapid heating of the way to avoid the phenomenon of burning, and in the heating process, the temperature should not limit the lower limit, If there is a burning situation, you should first cool it and then press it.
If you are heating a number of Dry Powder Pressing Molds, between each piece and each piece must be provided with a certain clearance during heating, and during the whole heating process, the parts must be flipped at all times to ensure that they are There will be no bonding between, to ensure that the product processing and use of normal.
After the cutting of the Dry Powder Pressing Mold in the contours and shape is still relatively poor degree of roughness, and pure structure and made from the contours of a large difference, mainly because of the cutting process, the plastic appeared serious Deformation, and we in the cutting time, the choice of the tool is also more important.
Because the different tools in the precision, as well as fine cutting high and low speed will have an impact, it is serious will affect the normal use of Dry Powder Pressing Mold. If it is for the brittle dry powder mold material processing, then the rate of cutting for the roughness of the impact is not large.
Dry Powder Pressing Mold is that we are in the preparation of metal powder or metal powder, and we call the metal powder and non-metallic powder mixture as a raw material, and then through the forming and sintering, and finally to the manufacturing Metal materials or composite materials and other types of products of a technology tool.
For dry powder pressing machine injection molding machine is concerned, we encountered a fault, then it is very common, this time we how to do it? Then for everyone to talk about this issue.
1: Dry Powder Pressing Mold injection molding machine pump motor and pump start, but no pressure up
This time may be dry powder mold pump oil pump on the proportional valve wiring loose or coil burned, so we should check the proportion of the pressure valve is through the electricity; there is impurities in the oil pump on the proportional pressure valve port, this time we will To remove the proportional pressure valve to remove impurities; Moreover, the pressure oil is not clean, found that accumulation of debris in the oil filter on the surface, the pressure oil into the pump had an obstacle, this time as long as the oil filter cleaning, and then replace the pressure Yes.
