Mold industry produces various molds and tools for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. to obtain the desired products. In short, a mold is a tool for forming an article, and the tool is composed of various parts, and different molds are composed of different parts. Because the aluminum mold has a density of only 36% of the general mold steel, the motion inertia is relatively low. In the production process, the deceleration is relatively easy, which can reduce the loss of the machine and the mold.
1. In the trial and kneading process, we should pay attention to the following aspects: A. The temperature of the front mold is determined by the temperature of the kneading mold. Is it necessary to reach the kneading temperature, and whether there is a transparent core (in the heating furnace) The placement of the mold is very important, and there must be a certain warming gap between the mold and the mold). B. The kneading mold must be aligned with the middle position and then prevent the occurrence of collapse and plugging. C. For different profile molds, choose the appropriate kneading speed to prevent too fast and too fast to form a poor discharge. D. In the process of kneading, we must pay attention to the quality of the aluminum rod to prevent the occurrence of mold collapse due to the problem of aluminum rod impurities.
2. Modification is a very important part, but the first thing to consider when repairing the mold is its strength. It is necessary to repair the mold on the basis of ensuring the strength of the mold. Soldering is usually not used to the extent of the final degree, since the welding has a serious influence on the life of the mold. In particular, the welding of the work belt is very simple to shorten the life. Regarding the correction of the profile speed, it is usually used to slow down the local repair rather than slow down the local slowdown. At this point, the reduction in the mold construction, to a certain extent, can ensure its life. Of course, improving the mold level and reducing the number of trials is also one of the ways to increase the life of the mold.
3. In the process of the model, it is especially important to pay attention to the part of the material, especially in some screw holes or weaker areas, otherwise it is very simple to smash the mold.
4. The transfer process of the mold should be carried out cautiously to prevent the bumps from hitting the work belt and so on. Before the mold is put into the warehouse, it must be cleaned and cleaned carefully and carefully, and the mold should be inspected with or without fine cracks and damage.
5. Regarding the finished mold, it is necessary to carry out useful processing of its technical data, such as the plan of repairing the mold, the details of processing, the technique of kneading. Since these can become a follow-up target for the mold or similar mold, it can be used to improve the qualification rate of the mold.
In general, the increase in the number of kneading molds depends on the perfect link between design, production, application and subsequent protection. By means of a single link, it is not useful to reach the intention. Through the useful combination of each link, trust can be improved in terms of the number of die life.

Resin Bond diamond and CBN Grinding Wheels
are made of either phenolic or polyimide resins. Pressure and heat are utilized
to bond the resin to our grinding wheel cores.
Phenolic bonded wheels can be utilized in dry or wet applications. Our
polyimide bonded wheels are best utilized in water or oil-based coolants for
improved form holding, typically required in CNC tool and cutter applications.
Resin bonded CBN Grinding Wheels are widely used on CNC machine for all tyeps of high speed steel cutter and drills machining and sharpening. They come mostly on shape of straight wheel of plat wheel, or bow shape wheel, or the working part can be sharpened to special shape like v shape or bevel shape.
A silicon carbide stone dresser is mostly used for the diamond or CBN grinding wheels.
Kemei produces all types and shapes diamond grinding wheels and CBN grinding wheels, and wheel dressers. If you need any grinding solution, contact us.
