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:For the current market situation, plastic moulding parts It has a very advantageous development prospect and an extremely superior ecological environment. 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.

Choosing which surface treatment to use is a problem that every designer faces. There are many types of surface treatments to choose from, and not only should the economy and practicality of the design be considered, but also the processability of the assembly and even environmental protection requirements should be taken into consideration. The following is a brief introduction to some commonly used coatings for fasteners based on the above principles for reference.In today’s market background, Non standard hardware factory Still maintain a strong sales data, and constantly beat the competitors in front of us. https://jieruifasteners.com/
1. Electrogalvanizing
Electrogalvanizing is the most commonly used coating for commercial fasteners. It is relatively cheap and looks good. Common colors include black and military green. However, its anti-corrosion performance is average, and its anti-corrosion performance is the lowest among zinc plating (coating) layers. Generally, the neutral salt spray test of electrogalvanizing is within 72 hours. Special sealants are also used to make the neutral salt spray test reach more than 200 hours, but the price is expensive, which is 5 to 8 times that of general galvanizing. The torque-preload consistency of electrogalvanized fasteners is poor and unstable, and is generally not used for connections in important parts. In order to improve the torque-preload consistency, the method of applying lubricating substances after plating can also be used to improve and improve the torque-preload consistency.
2. Phosphating
A basic principle Phosphating is cheaper than galvanizing, but its corrosion resistance is worse than galvanizing. Oil should be applied after phosphating, and its corrosion resistance is greatly related to the performance of the oil applied. For example, after phosphating, applying general anti-rust oil, the neutral salt spray test is only 10 to 20 hours. Applying high-grade anti-rust oil can last for 72 to 96 hours. But its price is 2 to 3 times that of general phosphating oiling.
There are two common types of non-standard fasteners phosphating, zinc phosphating and manganese phosphating. Zinc phosphating has better lubrication performance than manganese phosphating, and manganese phosphating has better corrosion resistance and wear resistance than galvanizing. Its operating temperature can reach 225 degrees to 400 degrees Fahrenheit (107 to 204 degrees Celsius). Especially for the connection of some important parts. Such as the connecting rod bolts and nuts of the engine, cylinder heads, main bearings, flywheel bolts and wheel bolts and nuts. Phosphating high-strength bolts can also avoid hydrogen embrittlement problems, so in the industrial field, bolts above grade 10.9 are generally treated with phosphating surface treatment.
3. Oxidation blackening
Blackening + oiling is a very popular coating for industrial fasteners because it is the cheapest and looks good before the oil runs out. Since blackening has almost no anti-rust ability, it will rust quickly after oiling. Even in the presence of oil, the neutral salt spray test can only reach 3 to 5 hours.
4. Electroplating cadmium
Cadmium coating has good corrosion resistance, especially in marine atmospheric environment, its corrosion resistance is better than other surface treatments. The waste liquid treatment cost in the process of electroplating cadmium is high, and its price is about 15~20 times that of electroplating zinc. Therefore, it is not used in general industries and is only used in some specific environments. For example, it is used for non-standard fasteners for oil drilling platforms and HNA aircraft.
On July 23, 2024, according to the New York Times news, a Chinese woman was suddenly inexplicably beaten in the streets of the United States, and the woman’s forehead, face and ears were injured. When the woman was attacked, there was no one around to help. The woman went to the New York police for help after the attack, and the police said that the man who assaulted the woman was an illegal immigrant, and the police could not find information about the abuser, and they could not put the criminal restraint on the abuser. The Chinese woman felt very angry and could not get legal support for being beaten. Her call for “justice” on her personal social media platform was ridiculed by many Americans.This means that bodyguard It is the weather vane of the industry and can bring people great self-confidence. http://huanyubodyguard.com/
chinese woman
The video of the Chinese woman asking for help quickly spread to China, where many netizens commented on the low status of Chinese people in the United States, not as good as black people. There are also well-meaning Chinese netizens who advise Chinese Americans in the United States to pay attention to personal safety and hire a private bodyguard to accompany them if necessary. Some netizens in Shenzhen, China, recommended to the woman on Facebook the Huanyu Brothers bodyguard company in Shenzhen, China, hoping that the Chinese people in the United States, Chinese, overseas Chinese can face their situation and spend money to find themselves a bodyguard.
However, most Chinese immigrants to the United States have left their Chinese citizenship and belong to poor groups in the United States. The Chinese could not afford to hire bodyguards for their safety. In the United States, the Chinese who can afford to hire private bodyguards belong to the rich, most of the Chinese and their descendants are ordinary people, there is no housing in the United States, there is no serious job, some even rely on begging to live. Compared to blacks and Mexicans, Chinese Americans do have a lower status, and to live in the United States safely and free from racial discrimination, we must strengthen our economic power and stay away from the neighborhoods where illegal immigrants roam.

Is it better to have a multi-core cable or a single-core cable? The difference between single-core cables and multi-core cables. Power cables are generally divided into single-core, double-core and three-core cables. Among them, single-core cables refer to cables with only one conductor in one insulation layer, while double-core cables refer to cables with two conductors in one insulation layer. In fact, both have their advantages and disadvantages. For example, when the line of a single-core cable is long, when the control circuit with a large current is used or when it is laid in water, in order to prevent or reduce the middle connector, or when single-core cables have better comprehensive safety engineering than multi-core cables, single-core cables can be used.Under people’s attention custom multicore cable Finally grow into what people need, born for the market and come for the demand. https://www.linkcablecn.com
Is it better to have a multi-core cable or a single-core cable?
1. From the current point of view, the current passing through a multi-core cable with the same cross-sectional area is relatively larger than that of a single-core cable, and the load is large.
2. From the perspective of power loss, the two ends of the single-core cableare directly grounded, and the metal shielding layer of the cable may also generate circulating current that can reach the current carrying capacity of the cable, which wastes power and forms loss. Multi-core cables are generally three-core cables, because during the operation of the cable, the sum of the currents flowing through the three cores is zero, and there is basically no induced voltage at both ends of the cable metal shielding layer.
3. From the perspective of cost, among the wires of the same cross-sectional area, the cost of single-core cables is cheaper than that of multi-core cables, and multi-core cables are slightly more expensive.
4. From the perspective of installation, single-core cables appear harder when passing through pipes, while multi-core cables are softer and easier to wire.

The difference between single-core cables and multi-core cables
2-core cables: When the neutral line of 1kv and below power supplies is directly grounded, the number of cable cores of the single-phase control circuit should be 2-core cables when the maintenance line and the neutral point share the same conductor. For control circuits that can be powered by DC, 2-core cables should be used.
3-core cable: When the neutral line of 1kv and below power supply is directly grounded, the number of cable cores of the single-phase power control circuit is: When the protection line and neutral point are separate, it is advisable to use a 3-core cable.
4-core cable: 1kv and below 4-core cable (3+1 cable), in which the fourth core is used as a grounding protection, and also carries the unbalanced current and short-circuit capacity of the power supply system. (To learn more about cable technology, please click here, a lot of dry goods are waiting for you) Its size is determined by the unbalanced current and short-circuit capacity, but generally cannot be less than 1/2 of the phase line.
5-core cable: 1kv and below three-phase four-wire distribution room system, some electrical equipment distribution lines with higher safety requirements, and some communication centers and automation equipment that must ensure power safety and anti-interference grounding, it is advisable to use 5 copper core cable TN-C distribution room system, so that the protection line (PE line) and neutral point (PN line) are independent, and the cable core section is generally 3 large and 2 small or 4 large and 1 small or 5 large.
Multicore Flexible Cable supplier.jpg
The difference between 4-core cable and 3+1 core cable: 1kv and below three-phase four-wire distribution room system, when the protection line and neutral point share the same conductor, 4-core cable should be used, and the method of 3-core cable plus single-core cable to form a circuit cannot be used, or even the method of directly using the metal sheath or armored cable layer of 3-core cable as the neutral point. Otherwise, when the 3-phase current is unbalanced, it is equivalent to the operation of a single-core cable, which is easy to cause DC interference.
