March 10, 2023 What is a cold box core shooting machine?

Core-making machine Core-making machine core-making machine Core-making machine core-making machine Casting equipment used to make cores. According to the different methods of real sand during core making, core shooting machines and core making machines can be divided into shock core making machines, core extrusion machines and core shooting machines. The vibrating core making machine is used to produce large and medium-sized sand cores that are hardened outside the core box, and can also be used for no-bake sand cores that are hardened inside the core box. It compacts the core sand by shock action. The core extrusion machine is used for sand cores with constant cross-sectional shape. The core shooter is a core-making equipment developed in the 1950s (Figure 1). The working principle of the core shooting machine is shown in Figure 2. When shooting sand, the compressed air quickly enters the sand shooting cylinder, pushes the sand particles through the gaps in the sand layer, and forms a sand air flow, so that the core sand is injected into the core box at high speed, and the core box is filled at the same time. Tight. The size of the core made by the core shooter, the surface is smooth. According to the shape and size of the core and the binder used in the core sand, the core shooting machine is divided into: ①The hot core box core shooting machine is a small and medium-sized core making machine with thermosetting resin as the binder. Heat hardens the core. ②The shell core machine is used to manufacture thin shell cores. The sand surface of the core sand is pre-covered with a phenolic resin film, which is hardened in a heated core box. ③The cold box core shooter is a small and medium-sized core making machine with resin as the binder, blowing air into the cold core box to harden the core. ④ Ordinary core shooters use vibrating sand buckets to add sand to make cores hardened outside the core box. Coated sand core shooting machine solves the problem of labor shortage in foundries flexible. The driving method of the coated sand core shooting machine is pneumatic, and it is used in conjunction with an air compressor. Equipped with mold cleaning and coating device. The machine is easy to operate and easy to use, even a lesbian can easily operate it. Equipped with a pneumatic sand feeding device, which can automatically add sand quantitatively. Thereby greatly reducing the labor intensity of workers. Special specifications can be designed and manufactured according to the needs of users. It can also design supporting designs and make molds for users. The advent of the coated sand core shooting machine has led to manual core making, and a part of it can also be made into a sand-coated shell casting method, which reduces the occupied area of the casting workshop, and how many layers can be stacked together. Simple, convenient, high utilization rate of molten iron. At the same time, the coated sand core shooting machine also solves the problem of labor sh...

  • March 10, 2023 Operation and method of water testing machine

      1. The water tester is used to test the glue effect of the glue strip. Air-tightness testing equipment is used to test whether there is water leakage, belt wear and other problems at the glued position in the form of hydraulic pressure. Generally test 3PSI for two minutes without water leakage, the bonding effect is considered qualified.   2. The test needs to be done step by step, first try IPSI/30 seconds, and slowly progress to 3PSI/2 minutes. Abnormal results caused by sudden pressure can be avoided.   3. Adjust the tightness of the "iron ring" of the water testing machine. If it is too tight, it will damage the rubber layer and film of the fabric, and the air tightness test will even leave marks on the fabric; if it is too loose, the water pressure will not meet the standard and cause not getting normal results   4. The glue layer and film of some fabrics are easily damaged, and the "iron ring" of the air tightness tester needs to add a layer of soft fabric. Prevent the "iron ring" from damaging the glue layer and film of the fabric.   5. The water used by the water testing machine must be clean and free of impurities, so as to avoid debris from clogging the pipes, and the waterproof tester will cause inaccurate data on the pressure gauge. The pipes and water container of the water tester need to be cleaned regularly.   6. When testing the water test machine, the airtight leak tester may have fabrics that are easy to absorb water, which should be handled carefully to prevent the fabrics from absorbing moisture and being difficult to dry, which will affect the subsequent processing and final packaging.    Choose D & S Automatic, we will provide you with the best service.

  • February 02, 2022 The working principle of the salt spray test machine

    The full name of the salt spray test machine is a salt spray test machine, which is mainly used to test the corrosion resistance of samples. At present, it is widely used in aerospace industry, automotive electronics, electronic electrician, mobile phone digital, plastic products, metal materials and other industries to test its corrosion resistance. It is also to simulate extreme conditions under natural conditions or working conditions to understand the properties of each sample. performance temperature. The working principle of the salt spray testing machine is relatively simple. It mainly uses corrosive gas and liquid to spray the sample. By spraying the corrosive gas and liquid until the corrosion of the sample occurs, the longer the time is as the corrosion resistance of the sample, the It means that the corrosion resistance of the sample is better. The working principle of the salt spray test is to compress the corrosive solution into an air spray, and then wrap the spray on all sides of the sample as much as possible. This test can be carried out continuously or cyclically until the expected corrosion phenomenon appears on the sample. The corrosion time is then recorded to indicate the corrosion resistance of the sample. Generally, the corrosion solution in the salt spray testing machine is mainly 5% sodium chloride solution or adding 0.26 grams of copper chloride per liter to the sodium chloride solution as a salt spray corrosion solution. In addition, the salt spray testing machine can independently adjust the settlement and spraying volume of salt spray to ensure constant test temperature, convenient operation and stable test environment. Therefore, it is often used to test the corrosion resistance of daily necessities or industrial products. Choose our D&S machines to provide you with the best salt spray testing machines.
