As a manufacturer, we also understand the problems that need to be considered in the production process of precision casting. For example, when producing some large castings, the tools or equipment selected must be different from the past, and the replacement and maintenance of the equipment should also be done well. Casting is inseparable from the mold, and choosing a good mold is also very critical. Moreover, high-quality tools and technology can complete the whole process of precision casting, and the precision degree can measure the quality of the castings we make, which is also a main reason why we value the precision casting process. When the production process is perfect, we should try our best to do these work and consider the problems thoroughly.
Pouring and gate of stainless steel castings are the two main processes. For Junya precision casting, good casting technology can achieve the most exquisite products. If casting products are not produced by good technology, their quality will also be reduced.
The pouring and gate design scheme of stainless steel castings is mainly shown as follows:
The cutting surface of the upper and lower castings of the mold shall be in the lower box as far as possible, because the shrinkage cavity in the lower part is small and the material is dense. The pouring methods include top pouring from the upper part of the casting and bottom pouring from the lower part and middle part. The top pouring mold is easy to produce sand flushing and is not often used. The position of the inner gate is determined because the molten iron flowing into the cavity is rapidly cooled into solid. If the inner gate is opened in the thick wall part, the molten iron cannot enter the thin wall part. When making large castings, if the inner gate is small, the molten iron will pass quickly. Sand washing is required near the inner gate. Its position shall be determined by considering the number and shape of the inner gate. We have made a detailed discussion on its pouring and gate, which I believe will be helpful to you.
The precision casting process can fully build the gear. So, since the superiority of this product is so strong, what technology is behind it? The answer can be found from the following discussion.
In the process of gear processing, advanced blank forming process, more stable and precise heat treatment process and especially suitable surface Petrochemical treatment procedure are the key factors for the final formation of high-quality gears. We can see several key links in grinding. By selecting the grinding wheel with sharp grinding edge and low grinding surface stress, we can improve the grinding feed, which will shorten the grinding time, improve the grinding efficiency, and prolong the grinding wheel dressing interval to reduce the cost. Precision casting technology can not only achieve high-quality gears, but also bring light to the gear industry, and create a batch of high-quality gears to be used in various industries.
The heat treatment of precision casting is easy to cause unreasonable micro-structure and excessive grain size, which will lead to the decline of main properties such as toughness, cold and hot fatigue performance and wear resistance of stainless steel castings, and affect the service life of precision casting work-piece. However, this refers to the result of improper heat treatment. As an intermediate link or final process in the manufacturing process of stainless steel castings, the cracking, deformation and performance caused by heat treatment are out of tolerance, which is easy to scrap the castings in most cases. However, this is mainly because we use improper heat treatment methods. However, heat treatment must be a step that needs our operation. However, its operation must be appropriate, otherwise it is easy to cause the above phenomena. If precision casting wants to make a good stainless steel casting, it must deal with the relevant links.
