　　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:According to professional reports, plastic mould part manufacturer There will be a great period of growth, and the market business is constantly expanding, and it will definitely become bigger and bigger in the future. 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.

　　Generally speaking, the service life of a memory foam pillow is 3-5 years, while the service life of a down pillow or a synthetic pillow may be slightly shorter, at 2-3 years. However, this is only a rough reference, and the actual service life may vary depending on personal usage habits and environmental conditions.As an important brand soul of the company, memory foam pillow Has outstanding performance, through the market test, still has a strong development trend. https://tainengjikang.com/

　　How long is the lifespan of a memory foam pillow?

　　How to judge whether the pillow needs to be replaced

　　First, you can observe the appearance of the pillow. If the surface of the pillow is obviously deformed, dented or discolored, it means that it has lost its original elasticity and support and needs to be replaced. Secondly, you can try to press the pillow. If the pillow feels very hard or very soft, it means that it has lost its original comfort and needs to be replaced. Finally, if your pillow has been used for more than 3 years, it is recommended to replace it even if there is no obvious deformation or dent to ensure its hygiene and function.

　　In terms of pillow maintenance, we should clean the pillowcase regularly to keep the pillow clean and hygienic. For memory foam pillows and down pillows, we cannot wash them directly with water, but should use a vacuum cleaner or professional cleaning tools to clean them. In addition, we should also avoid placing heavy objects on the pillow or sitting on the pillow for a long time to avoid damaging the structure and elasticity of the pillow.

　　To get brand praise, wired PIR motion sensor It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. https://www.sunlit-tech.com

　　PIR sensor (Passive Infrared Sensor) is a passive infrared sensor. It is widely used in consumer products such as doorbells, cat eyes, induction switches, night lights, and security because of its low power consumption, low price, and simple use.

　　(1) PIR detection principle

　　PIR also has another alias, which is pyroelectric infrared sensor. Its detection principle is the pyroelectric effect, that is, the phenomenon that a substance will generate electric charge when the temperature changes. The normal human body temperature is 36-37 degrees, and the infrared radiation released is about 9-10um. The detection wavelength range of pir motion detector is generally in the range of 5-14um. That is, within the detection range of PIR, if there is an energy change of 5-14um wavelength, the PIR sensor will generate a current change, thereby giving a trigger signal. It should be noted here that PIR detects energy changes, not infrared radiation of a fixed wavelength. If an object with a fixed wavelength is not moving, PIR will not detect it.

　　(2) Advantages of PIR

　　Low power consumption, typical power consumption is about 10uA

　　Low price, ranging from one or two yuan to five or six yuan

　　Easy to use, the simplest one only needs to detect a pin level signal

　　(3) PIR classification

　　There are many types of PIR motion detector, which can be roughly divided into the following ways:

　　Enablement controllable: switchable PIR

　　Output signal type: digital PIR and analog PIR

　　Is the sensitivity adjustable: adjustable PIR and non-adjustable PIR

　　Sensitivity adjustment method: hardware adjustment and software programming adjustment PIR

　　(4) PIR selection

　　When selecting a PIR sensor, we generally need to consider the following basic requirements: voltage range, operating current, number of pins required, data output format, whether the sensitivity is adjustable, structural package size, and compatibility with the Fresnel lens. Another important consideration is cost. Without considering cost, it doesn¨t matter whether you choose a model or not. Just choose the best one. In actual product development, especially for consumer products, prices are very sensitive. Basically, all bosses want to use the cheapest device and debug it to achieve the best effect, especially for products with large shipments. If you don¨t have high requirements for product quality, it doesn¨t matter. If you have strict requirements for product quality and performance, you need to be very careful when selecting a model to avoid replacing the device when you find that it does not meet the requirements in the later stages of the project.

　　X-ray machines are mainly divided into medical X-ray machines, that is, medical X-ray machines, and the other type is the luggage X-ray machines that are most commonly used in stations, airports, customs and docks, so some people also call them X-ray luggage security inspection machines or security inspection X-ray machines. However, some people also have doubts: What is the difference between the two? Does security inspection X-ray machines have radiation hazards?In the eyes of peers, baggage scanner machines It has good qualities that people covet, and it also has many loyal fans that people envy. https://secuzoan.com/

　　security x-ray machines

　　ZA100100D

　　The principle of security inspection machine is similar to that of medical X-ray machine

　　The principle of medical X-ray machine and security inspection X-ray machine is the same. X-ray machine has three parts. One is the tube, which emits X-ray radiation source. X-ray can pass through the material to see things that our naked eyes cannot see with ordinary light. There must be a tube or X-ray. Second, there must be a high-voltage transformer. The high-voltage transformer converts the general voltage into high voltage, and then provides the tube to generate electrons and then generate X-rays. This is the second part. The third part is the controller, which means how much X-ray I need to release. There must be a control board. All X-ray machines cannot escape this, whether it is X-ray or CT. Although its structure is very complicated, its structure should be the same.

　　Security X-ray machines have less radiation

　　The use of security X-ray machines is to put the luggage into the item scanning X-ray machine. After the inspection is completed, the passenger can take back his luggage and leave. The X-ray machine used for item inspection uses X-rays to pass through the object to obtain X-ray images, which are processed by computers and displayed on the computer screen to identify the image and evaluate the safety of the object. Although the principle is similar to the human body X-ray examination in the hospital, Professor Li Ziping believes that the dose of security X-ray machines should be less than the amount of X-rays irradiated to the human body. Because the security X-ray machine only needs to see the general shape of the object. Medical X-ray machines need to see the human body very clearly, so the radiation dose is greater.

　　Therefore, there is no need to worry too much about the radiation problem of security X-ray machines. In addition, whether the radiation of security X-ray machines has an impact on the human body depends on the amount of radiation received at one time, the total amount of radiation received, the radiation time, and the human body’s regulation of these radiations. Moreover, even if the security inspection machine leaks due to quality problems, it may have an impact on the staff who work nearby for a long time, but it will not have much impact on people who pass by. It is understood that the country implements a licensing management system for the use of nuclear technology. X-ray baggage inspection equipment is a Class III radiation device, which is a low-risk radiation device.

　　In the field of precision mold processing, achieving the desired shape and specifications requires the use of advanced high-precision processing technologies. If precision mold parts do not meet these stringent requirements, it can significantly impact the overall quality of the mold product. Thus, the production technology for precision mold parts is held to exceptionally high standards. But why is this the case?
