What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

What errors may occur during CNC machining and CNC machining​?

 CNC machining and numerical control machining are a method to control the movement of machine tools and the production process of machining through computer digitization and information digitization. It is an intelligent numerical control device developed as an economical, high-speed, reliable, multi-functional, intelligent, and open structure. CNC machining is also an important indicator that can measure the continuous level and comprehensive ability of a safety technology, as well as the degree of modernization of related science and technology capabilities, especially in aviation, biology, medical and other high-tech cultural industries, and it is also a powerful indicator. reflect. So, what errors may occur during CNC machining and CNC machining? Let us understand together:   The use of approximate machining motion or approximate tool contours causes errors in the CNC principle of machining. The reason why it is called machining principle error is because of the error in machining

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

Have all the operating procedures of the injection molding workshop been achieved?

               Start-up preparation
1. Make preparations before production.
2. Turn on the heating switch to heat up. Check whether the heating coil is working normally, and solve it in time if there are special circumstances or find relevant personnel to solve it.
3. Turn on the cooling water to prevent the high temperature in the latter part of the heating process from forming plastic backflow, which will block the feeding port and delay the normal start-up. And whether the cooling water pump is abnormal, whether the sound is normal, if there is any problem, solve it in time or find relevant personnel to solve it.
4. Before starting the machine, check whether the electrical appliances and mechanical safety devices of the machine are reliable. If there is any problem, fix it in time or find relevant personnel to solve it.
5. Check whether the fastening screws of the mold and the machine are loose, and whether the guide post and the guide sleeve are correctly inserted. If there is any problem, solve it in time to avoid unnecessary accidents or damage to the mold. Enter the corresponding injection molding benchmark process conditions according to the product name.

              Forming adjustment
1. Open the plastic machining mold and check whether there are foreign objects on the parting surface of the mold. If there are foreign objects, remove them in time to ensure that the parting surface is clean, so as not to crush or damage the mold and affect the accuracy of the mold.
2. When cleaning the plastic or impurities on the mold cavity or core, it is strictly forbidden to impact the mold cavity and core with iron or other hard metals to avoid damage to the mold.
3. Lubricate the guide post, guide sleeve and other sliding parts of the mold.
4. When the temperature of the barrel is reached, keep it warm for another 5 minutes to ensure that the plastic in the barrel is fully melted, and the machining uhmw plastic cannot be forced to start or predict, so as not to damage the screw and the inner wall of the barrel.
5. Without clamping the mold, it is strictly forbidden to advance the injection seat to avoid damage to the mold or accidental injury caused by the falling mold. Formal production
6. After the machine is turned on, the person in charge will take the first 5 molded products and confirm the first piece. The confirmation result is recorded in the "First Article Inspection Record Form". And notify the engineering inspector that the equipment has entered the production state.
7. After entering the formal production, record the actual production process conditions in the "Injection Molding Process Record Sheet".
8. During production, the personnel in charge need to clean the cnc machined parts molds and machines and update the grease every shift.
9. Temporary shutdown due to alarm or other reasons. When re-production, the first 2 molds should be discarded, and then 2 molds should be taken to confirm the appearance of the molded product.
                   shutdown
1. After the production reaches the production instruction quantity, close the hopper inlet and switch the molding machine to the "semi-automatic" state.
2. After cleaning the mold a little, spray anti-rust agent on the PL surface of the mold.
3. Turn off the mold cooling water 5-10 minutes before shutdown, and blow out the mold cooling water after shutdown.
4. Take out the excess material in the hopper, and clean up the part that cannot be taken out.
5. Clean the screw. If machining uhmw, PP, PE, PS, ABS raw materials, there is no need to clean the screw; to produce other raw materials (such as PVC material), you need to clean the screw with cleaning materials.
6. Screw cleaning method. After the production of PVC.POM raw materials, they are directly cleaned with cleaning materials. After PC and PA raw materials are produced, they are cleaned with cleaning materials first, and then the temperature of the barrel is lowered to 200 degrees, and then cleaned several times.
7. After the screw is cleaned, shoot the screw to the end.
8. At the end of production, the mold should be closed, but the mold should not be closed tightly, so that the movable and fixed molds should maintain a gap of 0.5-1mm.
