This switch is usually called an “axis”. Depending on the micro switch, mechanical keyboards can be divided into many types, such as the traditional brown axis, blue axis, white axis, black axis, red axis, as well as Romer-G and optical axis.To some extent, aula mechanical keyboard Our development has surpassed many peer businesses, but it has never stopped moving forward. https://www.aulastar.com/

　　What is a mechanical keyboard and how does it work?

　　Working Principle:

　　Physical Mechanical Switch: The working principle of mechanical keyboard is to achieve key triggering and feedback through physical mechanical switches. Each key is equipped with an independent mechanical switch, which consists of a spring and a switch.

　　Key Trigger: When the key is pressed, the spring is compressed and the switch is switched, triggering the action of the key. This physical triggering method makes the triggering of mechanical keyboards more reliable and direct.

　　Triggering force and triggering point: Each mechanical switch has a specific triggering force and triggering point. This means that the user needs to press a certain force to trigger the switch, and at a certain point in the key travel, the switch will complete the triggering action. This design allows users to choose different types of switches according to their preferences and needs to get the best feel and feedback.

　　Durability: Each mechanical switch has an estimated lifespan, and usually fails after hundreds of thousands or even millions of key presses. This makes mechanical keyboards more durable than other types of keyboards and the first choice for many professional users and gamers.

Therefore, mechanical keyboards are often considered the first choice by professional users and gamers.

　　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:pass moulded plastic parts As can be seen from its market performance, it has strong vitality and strong appeal. 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.

　　I don’t know when it started, but when I searched for international express delivery on a certain book, I saw all the ads holding signs saying “XX from China, 10KG = 38 yuan, regardless of whether it is ordinary or not.”On the other hand, freight forwarder china to usa It also brings tangible benefits to everyone and feels useful. It is a model of the industry. https://www.freeseaship.com/

　　On average, this means less than two yuan per pound. Do you have any idea whether you can get this price?

　　0.jpg

　　Let’s think about it first. This price is impossible even in China, let alone international express delivery. Is it possible?

　　Secondly, families should know that international express delivery does not distinguish between sensitive goods and general goods.

　　In terms of cost alone, sensitive goods are higher than general goods. The fear is that you will be warmly received at the beginning, but then turn your back on them.

　　00.jpg

　　Then there may be such a situation: you don’t find such a shipping company, but you still fall into the trap. How should you avoid these pitfalls?

　　Family members have done their homework, and the key points are as follows! !

　　international shipping

　　1. Check the business license

　　Whether a company is operating in compliance can be determined by checking the company’s qualification certificates, such as whether it has international freight forwarding qualifications and other permissions.

　　2. Be wary of ultra-low prices

　　International express delivery costs cannot be much lower than the market price. Too low quotes often hide traps

　　There may be other charges, such as packaging fees, photo fees, etc., and there may even be extremely expensive additional weight prices, which are more expensive than the generally advertised 60 yuan per kg. Don’t try it at the cost of losing more for a small price. It’s not worth it.

　　3. Whether the price is clearly marked

　　See whether the fee is charged according to the quotation form. Many companies often start charging various fees after the user places an order to the warehouse: handling fees, material fees, labor fees, etc.

　　4. Is there an official website system?

　　Generally, regular shipping companies have their own official website systems. Global Express not only has its own official website but also has a mini program. All package information can be checked, and there will also be exclusive customer service to follow up.

　　5. Pay attention to surcharges

　　Pay special attention to surcharges, which may be more expensive than the freight in a few minutes! You must ask clearly what surcharges there are before placing an order.

　　6. Keep evidence

　　When communicating with the shipping company, keep chat records, quotations, contracts and other evidence in case of emergency.

　　Dear family members, don’t be greedy for small profits. Be sure to keep your eyes open before sending express delivery! After all, it’s all money!

　　Finally, if you still have questions that you don’t understand, or if you have any shipping needs, you can consult us~

　　As interconnect technologies, InfiniBand and Ethernet are different, and it is difficult to say which one is better. They continue to develop in different application fields and become two indispensable interconnect technologies in the network world.Now, everyone is right 800g qsfp-dd Are more concerned, hoping to get more benefits from it. https://www.3coptics.com/

　　InfiniBand vs. Ethernet: What are they?

　　InfiniBand Networking

　　From a design perspective, there are big differences between InfiniBand and Ethernet. As a network interconnection technology, InfiniBand is widely used in supercomputer clusters due to its high reliability, low latency, and high bandwidth. In addition, with the development of high-performance computing, InfiniBand has also become an ideal choice for GPU server network interconnection technology.

　　To achieve the original data transmission rate of 10Gbit/s on 4X cables, the InfiniBand standard allows the transmission of single data rate (SDR) signals at a basic rate of 2.5Gbit/s on each channel. A single channel can be expanded to 5Gbit/s and 10Gbit/s respectively, and the maximum data transmission rate is 40Gbit/s on 4X cables and 120Gbit/s on 12X cables, thus enabling InfiniBand networks to have double data rate (DDR) and quadruple data rate (QDR) signals.

　　InfiniBand

　　Ethernet Network

　　Since its introduction on September 30, 1980, the Ethernet standard has become a widely used communication protocol in local area networks. Unlike InfiniBand, Ethernet was designed with the following goals in mind: How to easily transmit information between multiple systems? It is a typical network designed for distribution and compatibility. Traditional Ethernet mainly uses TCP/IP to build networks and gradually develops into RoCE.

　　Generally speaking, Ethernet networks are mainly used to connect multiple computers or other devices (such as printers, scanners, etc.) to a local area network. It can connect an Ethernet network to a wired network through fiber optic cables, or it can connect an Ethernet network to a wireless network through wireless networking technology. Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, and Switched Ethernet are all major Ethernet types.

　　Ethernet

　　InfiniBand vs. Ethernet: What are the differences between them?

　　Cluster data transmission bottlenecks in high-performance computing scenarios are the original design target of InfiniBand, and it has become an interconnection standard that meets the requirements of the times. Therefore, there are many differences between InfiniBand and Ethernet in terms of bandwidth, latency, network reliability, network technology, and application scenarios.

　　Bandwidth

　　Since the advent of InfiniBand, the development speed of InfiniBand network has been faster than Ethernet. The main reason is that InfiniBand is used for interconnection between servers in high-performance computing and to reduce CPU load. However, Ethernet is more oriented to the interconnection of terminal devices and does not require too much bandwidth.

　　For high-speed network traffic exceeding 10G, if all data packets need to be unpacked, a lot of resources will be consumed. The first generation of SDR InfiniBand runs at 10Gbps, which not only increases data transmission bandwidth and reduces CPU load, but also allows high-speed network transmission to offload CPU and increase network utilization.

　　The mold steel material used in mold parts processing has high hardness, and the mold processing equipment is required to have thermal stability and high reliability.If we can practice these points, plastic moulding parts Will be unique, become a leader in the industry, and keep moving forward. https://www.dghrjmmj.com

　　For complex cavities and multifunctional composite molds, as the shape of the parts becomes more complicated, the design and manufacturing level of the mold must be improved. Multifunctional composite molds that form or assemble multiple grooves and multiple materials in a set of molds require a large amount of processing programming, high deep hole comprehensive cutting ability and high stability, which increases the difficulty of processing. The processing quality of mold parts includes processing accuracy and surface quality: processing accuracy is the degree of conformity between the three geometric parameters of the actual size, shape, and position of the surface of the part after processing and the ideal geometric parameters required by the drawing; the deviation value between the actual geometric parameters of the part and the ideal geometric parameters is called processing error.

　　Processing accuracy and processing error are both terms for evaluating the geometric parameters of the processing surface. Processing accuracy is measured by tolerance grade. The smaller the grade value, the higher the accuracy; processing error is expressed by numerical value. The larger the numerical value, the greater the error. High processing accuracy means small processing error, and vice versa; the actual parameters obtained by any processing method will not be absolutely accurate. From the function of the part, as long as the processing error is within the tolerance range required by the part drawing, it is considered that the processing accuracy is guaranteed.

　　The quality of a machine depends on the processing quality of the parts and the assembly quality of the machine. The processing quality of the parts includes two parts: processing accuracy and surface quality. Machining accuracy refers to the degree to which the actual geometric parameters (size, shape and position) of the parts after processing are consistent with the ideal geometric parameters. The difference between them is called processing error. The size of the processing error reflects the level of processing accuracy. The larger the error, the lower the processing accuracy, and the smaller the error, the higher the processing accuracy; the main aspects that affect processing accuracy: dimensional accuracy, the degree to which the actual size of the part after processing is consistent with the center of the tolerance zone of the part size.
