Mold accessories are mainly parts or components installed on the mold. They can be widely used in various plastic molds, stamping molds, automobiles, electrical and aviation manufacturing fields. However, for mold accessories, the better the quality, the longer the life. Therefore, it is a problem that we all pay close attention to to understand the factors that affect the quality of mold accessories. Do you know what factors affect the quality of mold accessories? Hairong Precision introduces you below:To some extent, plastic moulding parts Our development has surpassed many peer businesses, but it has never stopped moving forward. https://www.dghrjmmj.com

　　The factors that affect the quality of mold accessories are as follows:

　　1. Rationality of mold accessory design

　　Mold accessory designers should first fully understand the user’s use requirements and working conditions, and the situation of die-casting force, and then select suitable materials according to the use requirements and working environment, and understand the die-casting performance of the materials. In the design of mold accessories, special attention should be paid to the premise of meeting the use requirements, and the die-casting structure should be as simple as possible. The wall thickness should be appropriately uniform, and the necessary mold slope should be left, otherwise it will cause pits, pores, shrinkage, underpressure, stretch marks, cracks, deformation and other defects on the casting. The requirements for the dimensional accuracy of the casting should be reasonable, otherwise it will bring unnecessary troubles to the mold design, mold processing, process condition formulation and management, and will cause a large number of unqualified products.

　　2. Mold structure, processing accuracy and mold material

　　The selection of mold accessories for die casting is closely related to the product quality of die casting, mold design, processing, mold material selection, etc. If the mold structure is unreasonable, it is difficult for mold accessories to make the product qualified no matter what measures are taken from the process. In addition, the mold material, mold processing accuracy, surface roughness, processing marks, small cracks in heat treatment, nitride layer thickness and mold assembly of heat-resistant and wear-resistant mold accessories will affect product quality and mold life.

　　3. Shrinkage rate of mold accessories

　　The shrinkage rate of casting materials is generally expressed as an average percentage or a percentage of a certain range of variation. The average shrinkage rate of the material is usually selected. For the design of high-precision die castings and molds of mold accessories, special attention should be paid to the selection of material shrinkage. If necessary, the mold can be tested first, the required data can be obtained in the test mold, and then the production quantity of large molds designed and manufactured can be carried out.

　　To sum up, these are the factors that affect the quality of mold accessories. In order to better ensure the quality of mold accessories, we try to choose the best structural solution in the design process. The designer of mold accessories must fully consider the technical requirements and structure of the parts, and must meet the processability and feasibility of mold manufacturing.

　　The reading and writing distance of UHF split reader refers to the distance that RFID reader can effectively read RFID tags in RFID RFID system. How far is the reading distance of UHF split reader? The reading distance of UHF is generally 3-5 meters, and the farthest can reach 15 meters. The split reader can be connected with multiple antennas, and it can read a longer distance if the antennas are connected. The specific reading distance is influenced by many factors, including but not limited to the power of the reader, the gain of the antenna, the types and characteristics of RFID tags and environmental factors. The following is a detailed analysis of the factors affecting the reading distance of UHF split reader.pass rfid module supplier As can be seen from its market performance, it has strong vitality and strong appeal. https://www.vanchrfid.com/

　　Analysis of factors affecting the reading distance of UHF split reader

　　1. Reader power

　　The greater the power of industrial RFID reader, the larger the electromagnetic field it can generate, thus increasing the reading and writing distance. For example, the maximum output power of some UHF readers can reach 30 dBm (or higher), which determines the upper limit of their reading and writing distance to some extent.

　　2. Antenna gain

　　Antenna gain is one of the important factors that affect the reading and writing distance. The greater the antenna gain, the greater the intensity of the electromagnetic field generated by the reader in a specific direction, thus increasing the reading and writing distance. According to the reference article, the reader equipped with 8dBi antenna can reach the reading and writing distance of 0~20 meters for ordinary tags.

　　3. Types and characteristics of RFID tags

　　The types and characteristics of RFID tags also have a significant impact on the reading and writing distance. Theoretically, the larger the size of RFID tags, the more distant UHF readers can read them.

　　4. Environmental factors

　　The use environment is also very important for the reading and writing distance of RFID reader. Metals and liquids have great influence on UHF performance. Therefore, if it is used in metal objects or working environments with many metal influences, it is necessary to use metal-resistant electronic tags, so as to reduce the influence of metals on tag data signals and facilitate the normal use of RFID electronic tags.

　　Industrial RFID reader

　　ANDEAWELL UHF split reader RU5321M&T-S04 can be connected with four antennas to work at the same time, which is convenient for distributed installation and deployment of antennas. The reading distance can reach 0~5000mm (the farthest distance is related to the label size), and the protection level is IP67. It is suitable for all kinds of harsh environments in the industrial field; Built-in filter and isolation module has strong anti-interference ability, high receiving sensitivity, stable performance and strong reliability. It supports standard industrial communication protocol ModBus and is convenient for users to integrate into control systems such as PLC.

　　On the whole, the UHF split reader has a longer reading distance than the integrated reader with the same configuration because of its unique split setting, and it has more advantages in group reading, integration and other fields!

China-Singapore, Beijing, July 16 (Reporter Sun Zifa) Springer Nature’s professional academic journal “Nature Astronomy” recently published a planetary science paper saying that researchers have discovered a potentially accessible underground tunnel originating from an open pit on the moon. Evidence of tunnel. The results of this study have enhanced people’s understanding of lunar geology and may become an ideal location for a lunar base, thus potentially serving as a refuge in future manned missions on the lunar surface.

The paper said that more than 200 craters known as skylights have been discovered on the lunar surface, some of which were formed after the collapse of underground lava tubes. Accessible lava tubes or channels may provide a warmer environment than the lunar surface, but it has previously been uncertain whether they can lead to large underground caves.

In this study, co-authors of the paper, LC and LB of the University of Trento in Italy, and collaborators, analyzed radar data from the Lunar Reconnaissance Orbiter and found that radar brightness on the west side of the crater increased. Jinghai Crater is the deepest known crater on the moon, with a radius of approximately 100 meters, with vertical or overhanging walls and a sloping bottom.

The authors of the paper used radar images to conduct simulations and found that these observations could be explained by the presence of a cave void or pipe spreading from the west side of the bottom of the pit. They estimate that the pipeline is located at a depth of 130-170 meters, 30-80 meters long and about 45 meters wide. The cave may be flat or inclined at an angle of up to 45 degrees and may be accessible.

The authors concluded that the pipes or channels discovered in this study may be a common feature under the lunar plains, and that the Jinghai Pit and its channels may be an ideal site for a potential lunar base. The method used in the study may also be suitable for evaluating and characterizing other lunar craters to discover more channels.
