How To Choose High Quality And Suitable Pellet Machine Mould

1. The pellet machine mold processing equipment is an important factor in determining the quality of the mold. At present, all regular pellet machine mold manufacturers use CNC machine tools for production. However, the poor-quality pellet machine mold uses an old-fashioned lathe that cannot achieve the required machining accuracy! In addition, the production of this kind of mold itself is imitation, and it is difficult to ensure the accuracy of the main mating surfaces and processing dimensions. The mold hole processing technology of the sawdust pellet machine is very particular. It has neatly arranged mold holes and the whole wall is as smooth as a mirror surface. Etc. However, most of the mold holes of inferior molds are processed manually by small drilling machines. The inner walls of the holes are rough and there is ribbing. The compression ratio of the mold is different, which makes it difficult to discharge the mold, and it is easy to block the mold and block the machine, which increases the electricity consumption and reduces the production capacity. The appearance of the particles is not smooth, and the length of the finished material is uneven, especially when the machine is blocked, the temperature in the extrusion cavity of the die rises rapidly, and it is easy to burn out the roller bearing and the spindle bearing, and the working load increases, which makes the sawdust pellet machine. Large and small gears wear faster.

2. The raw material of the pellet machine mold is another important factor in determining the pellet machine mold. At present, the most commonly used raw material for pellet machine mold is alloy steel, and the other material is stainless steel. However, the inferior pellet machine molds are made of ordinary steel that cannot achieve such strength. You must know that the wood pellet machine produces some coarse materials, so the requirements for wear resistance and strength of the pellet machine mold are very high! Molds made of this common steel have a short service life and are prone to cracking. If such a mold is selected, it will not only waste the capital investment of the enterprise due to frequent replacement of molds but more seriously, there will be hidden dangers in production safety.

3. The processing of inferior molds is mostly imitation, and its processing accuracy cannot be controlled, plus the accumulation of errors in various aspects. If this mold is used for a long time, the normal work of the pellet machine will be seriously affected, and the safety of the pellet machine cannot be achieved at all. , the purpose of high yield and low consumption. After careful calculation, although the purchase price of inferior molds is lower, the economic benefits of the enterprise will be affected if the pellet machine frequently fails, the parts and bearings are frequently replaced, the output is reduced, and the power consumption is increased, and the manpower is wasted. In order to make your pellet machine achieve the purpose of high product quality, high output, low power consumption, and production safety in the production process of fuel pellets give full play to the working efficiency of the pellet machine. It should be noted that the pellet machines produced by different pellet machine manufacturers are different, and there may be differences in the pellet machine mold. The use of molds produced by other manufacturers may not be applicable!

4. The quenching process of the pellet machine mold is an important part of mold manufacturing, and the mold quenching process is very particular. At present, it is difficult for small mold manufacturers to have this advanced equipment. Generally, the quenching of the earth method is used in the pit furnace. This equipment cannot automatically control the temperature of the mold quenching, resulting in inconsistent hardness between the outside and the inside of the pellet machine mold after quenching, and the deformation coefficient is relatively high. Large, the mold is easy to be out of round. During the operation of the pellet machine using this mold, the pressure roller will frequently hit the mold, which will increase the vibration and noise of the wood pellet machine. It is also an important factor in the damage to the main shaft and the empty shaft. If the bearing of the empty shaft is damaged or runs off the inner and outer rings, the main shaft and the empty shaft may be scrapped. If the bearing hole of the main engine box is worn, not only will the pellet machine work weakly, but the output will be significantly reduced, and also the pellet machine will not work properly. The quality of the quenching process directly determines the hardness of the pellet machine mold and the wear resistance of the mold, and directly affects the use time of the pellet machine mold!
