Triple Qualitative Design of Precision Mold(2020)

There are seven main steps in the process of producing precision injection molds, also known as seven systems. Among these seven systems, the positioning system is an important part of precision injection mold design. If the design is unreasonable, the injection mold will be damaged, the specifications do not meet the requirements, and the processing is misaligned. Therefore, we must pay attention to the rationality of the positioning system in the design of precision molds.

The first requalitative: the initial positioning of the mold is completed by the guide column guide sleeve on the mold frame. The cooperation between the guide post and the guide sleeve is a clearance fit. For example, the MISUMI precision-level guide post and guide sleeve have a diameter of 25MM, and the clearance is between 0.02-0.03MM. If it is not properly matched, it is easy to cause mold wear, and the degree of wear will be more serious, and the gap between the final molded product and the drawing product is large.

Second qualitative: usually completed by the precise positioning of the sides on the die frame, the precise positioning of the cylinder, etc. This certainty is to compensate for the positioning error of the first qualitative effect as effectively as possible, so the cooperation requirements between the mold frames are more strict, and the cooperation accuracy is within 0.01MM. At the same time, the lifting error of the mold on the machine can also be avoided.

The third qualitative: the positioning of tiger mouth. With the development of CNC technology, Hukou positioning technology is being used in more and more factories. The purpose of making the tiger’s mouth is to accurately position the dynamic and fixed mold kernel, so the angle of the tiger’s mouth is more than 1 ° smaller than the break angle of the mold kernel, and the height is more than 2MM.

Precision mold design and processing must pay attention to these three qualitative characteristics. As long as these three points are well done, the problems of low mold accuracy and large errors will not usually occur. If these three qualities are ignored, if there are errors in the products produced, they will need to be reprocessed, which is a waste of time and technical difficulty is higher than the first manufacturing.

Why we need a solar framework？

If you want to install solar photovoltaic cells, then you must need a solar aluminum frame. To customize the solar aluminum frame, choose Jiangyin Mingding Aluminum Products Co., Ltd., a high-quality solar aluminum frame manufacturer from China.

Why is the solar aluminum frame a must for photovoltaic cells? Because solar cells need to be covered in a large area and need a metal frame to fix them, this requires the metal frame to have good performance and not be easily rusted. Although stainless steel is also a good choice for solar frames, the cost of stainless steel is much higher than that of solar aluminum alloy frames, so more people are willing to choose solar aluminum alloy frames. And aluminum alloy also has the advantages of wear resistance and corrosion resistance, light weight, easy installation, and easy to disassemble, it is a necessary choice for home solar cell installation.

Motor housing material, pig iron motor housing(Update)

Most motor casings are cast from iron, and iron is divided into pig iron and wrought iron. We generally use pig iron to cast the motor casing.

In the modern manufacturing industry, wrought iron is generally not used in factories, because the mechanical properties of wrought iron are too poor to meet the casting requirements in modern manufacturing. Although the products made by wrought iron are good in ductility, they are easily deformed. The protective product of the shell is not applicable.

The difference between wrought iron and pig iron is the difference in carbon content. The carbon content of pig iron is generally 2-6.69%, also called cast iron. Due to the high carbon content, pig iron is harder and wear-resistant, and has good castability. It is more suitable as a motor housing and protects the motor. In addition, the price of pig iron is much lower than that of wrought iron, so using pig iron as the raw material of the motor casing is the best choice!

Custom motor housing, pig iron motor housing, plastic motor housing, please go to Suzhou Santian Precision Mold Co., Ltd., we will provide you with the best quality service and the highest standard products.

3 major causes of blade damage

If the industrial fan blades are damaged, the entire industrial fan cannot work. Most blades are damaged due to vibration fatigue. Vibration fatigue is mainly divided into: forced vibration fatigue, resonance fatigue and flutter fatigue.

1. Forced vibration fatigue: It means that the blade has been subjected to the force of forced excitation when it is working, but the magnitude and frequency of the excitation force are different, so the damage to the blade is also different for a period of time.

2. Resonance fatigue: Resonance fatigue of blades has always been the focus of blade research, because most blades are damaged and malfunction due to resonance fatigue. The fracture feature caused by resonance fatigue is that there is a fatigue source on the surface of the fatigue crack. After the fatigue source is formed, it develops from the source point to form a shell-shaped fatigue ring.

Two conditions required for resonance fatigue damage: ① reach a certain alternating stress ② vibrate to a certain time

3. Flutter fatigue: Flutter fatigue is caused by blade flutter, and is also called low cycle fatigue. Although there is little flutter fatigue, it is the most harmful. The blade flutters, which is characterized by large amplitude, large vibration stress, and accompanying squeal noise, which can cause serious damage to the blade in a short time.

Acid etching treatment of industrial aluminum profiles

How do industrial aluminum profiles achieve a bright surface? This requires acid etching. The acid etching treatment technology of industrial aluminum profile is to transform the traditional acid etching bath, adding sand polishing tank and plane polishing tank to perform bright treatment on the acid etching material, so this process is also called bright acid etching technology.

Bright acid etching technology is composed of four processes: degreasing and dewaxing, brightening and acid etching, sand surface polishing and plane polishing. These four processes cooperate with each other and are indispensable. It is a perfect set of industrial aluminum profile brightening technology.

The main points of bright acid etching technology operation:

1. Reminder for slot setting: there is no water washing tank between the brightening acid etching tank and the sand polishing tank

2. Slot function description: degreasing and dewaxing tank, brightening and acid etching tank, sand polishing tank, flat polishing tank, anodizing tank

3. Description of process operation method: the industrial aluminum profile is degreased after 1-4min, after one wash, it enters the brightening and acid etching tank, after 4-12min, it directly enters the sand surface polishing tank, and after 3-9min, it undergoes another wash Enter the flat polishing tank, wait for 3-7min, after two water washings, and finally perform anodizing treatment.

3 factors affecting the cooling of industrial fans(Update)

Why turn on the industrial fan to dissipate heat, but it has no effect? Why is the cooling effect of my industrial fan so poor? If you want to avoid the above problems, you need to pay attention to the following three points when purchasing industrial cooling fans.

1. Speed

The speed of the fan refers to the speed of rotation of the fan, which is usually measured by the number of rotations in one minute, that is, the RPM marked on the fan. The higher the RPM, the faster the fan speed and the better the cooling performance of the fan. However, it should also be noted that the greater the speed of the fan, the noise and vibration will increase accordingly. Suzhou Santian Precision Mould Manufacturing Co., Ltd. recommends that you choose a low-speed fan that meets the heat dissipation requirements when purchasing the fan.

If you don’t mind the noise and vibration, you should pay attention to whether the bearing of the fan is safe and can withstand the high-speed rotation of the fan when purchasing an industrial fan, so as to prevent the fan bearing from breaking at high speed, which is very dangerous!

2. Number of blades

The industrial fan rotates the blades to make the air flow, thereby generating wind and achieving the purpose of heat dissipation. The amount of air volume generated also has a certain relationship with the number of industrial fan blades. Generally speaking, it is best when the number of industrial fan blades is 3, and the air volume generated at this time is the largest. The 5-blade industrial fan on the market does not generate as much air as the 3-blade industrial fan, but the noise emitted is much smaller. Suzhou Santian Precision Mould Manufacturing Co., Ltd. recommends that you buy a three-blade industrial fan, and do not choose to buy an even-numbered industrial fan, because this does not meet the balance principle of rotational dynamics, and it is easy to cause blade collision and damage.

3. Air volume and pressure

The air volume and air pressure of an industrial fan refer to the speed of air flow and the resistance to air supply it can produce. The measurement of air volume and pressure requires professional tools, so we can generally only use the data provided by the manufacturer as a reference.

The unit of air volume is m³ / s. When the value is larger, it means that the air volume of the industrial fan is larger, then the air absorbs more heat, and the heat dissipation effect is more obvious.

Wind pressure is the most difficult to judge. Generally, manufacturers rarely write wind pressure on product data, which can only be experienced by the purchaser.

Suzhou Santian Precision Mould Manufacturing Co., Ltd. recommends that you can pay attention to these two data when purchasing industrial cooling fans. If not, you can ask the manufacturer. If the manufacturer does not know, you may try it yourself and make a decision. Don’t be deceived!

Can a car work with a single cooling fan?

Most car cooling fans have two, and some even have more cooling fans. If your car cooling fan is broken, can a single Vehicle cooling fan support all the responsibility for heat dissipation? Can I still use my car?

Suzhou Santian Precision Mould Manufacturing Co., Ltd. reminds you: now, immediately, immediately, repair the broken cooling fan! Don’t be lucky.

The importance of car cooling fans must be understood by anyone who owns a car. It can protect the engine of the car, prevent the excessive heat generated by the engine from working and cause the engine to malfunction or damage other parts, so that your car can run all the time, and it will not malfunction or cause other safety accidents due to the high temperature of the car engine.

When your car has two or more cooling fans, it means that the temperature caused by your car engine needs so many cooling fans to dissipate heat to ensure normal operation. If any one of the cooling fans breaks, it may cause the car engine to dissipate heat in a timely manner or the heat dissipation efficiency is low, resulting in vehicle failure. So don’t be lucky. Once you find a problem with the cooling fan, repair it in time to ensure your personal safety. I believe that the price of repairing or replacing a cooling fan is often much cheaper than the price of repairing or replacing an engine.

Some people may say that the cooling fan of my car is broken, but it can still be used normally. Don’t worry, it’s just a matter of time. When the parts in the car can no longer bear, the money you pay will make you regret not replacing the broken cooling fan earlier.

Purchase a cooling fan and go to Suzhou Santian Precision Mould Manufacturing Co., Ltd.!

What are the temperature sensor housing materials?

The temperature sensor is one of the most frequently used sensors. We all know that the sensor needs to be protected by the sensor casing to ensure that the sensor can work normally, and extend the service life of the sensor and improve the performance of the sensor. What are the temperature sensor housing materials?

The temperature sensor housings currently on the market are: plastic sensor housings, stainless steel temperature sensor housings, copper sensor housings, copper sensor housings, aluminum sensor housings, etc. There are many types of temperature sensor housings, but different types of sensor housings need to go through different processing techniques to provide protection when the temperature sensor is working.

The copper sensor housing needs to be polished; the aluminum sensor housing needs to be oxidized; the plastic sensor housing needs no additional treatment to perfectly protect the temperature sensor.

Since the temperature sensor housing is a precision stamping part of hardware, when choosing a temperature sensor housing, you need to check whether the sensor housing meets the specifications of the temperature sensor. Suzhou Santian Precision Mould Manufacturing Company accepts customization of temperature sensor housings of various specifications. If necessary, please contact us!
