The price and quality of the heap high machine

Now the price and quality of the product in the market are in direct proportion, take the most inseparable mobile phone in our daily life, why there are more than 1000 mobile phones with a price of seven thousand or eight thousand, some people say it is the configuration and brand reason of the mobile phone, but more than 1000 of the mobile phones may use the card. The battery does not store electricity, and so on and so on. These are the direct proportion of the price of the product to the quality. Here is a heap of high machines to explain.
Before a article and everyone said about the high machine where the problem of cheap, in fact, the two problems are interlinked, when the manufacturing cost of the high machine down, the price of the high machine down naturally down. Some people shoddy work on the material of production, which means reducing the quality of products. Only by reducing labor losses can we reduce costs.

Common methods for color matching of plastics

Our common plastic color matching is two, one is manual color matching, and another is mechanical color matching.

Manual color matching, its color matching personnel must have rich experience in color matching. Before color matching, he must have a clear understanding of the colorants he needs. In order to master the general rules of coloring, we should have a clear understanding of the properties of the coloring agents, such as hue, color, mobility, heat resistance, weather resistance, chemical stability and so on, and accumulate the experience of various kinds of plastic coloring samples and color matching. Before finding the appropriate colorant formula, a lot of debugging must be done first, and the color of the same color is repeated repeatedly until the required color is obtained. Obviously, the visual color matching method is a trial and error method, not very scientific. Because this method is simple and practical, it is still widely used. But this method takes time and requires a lot of experience from operators. Otherwise, it will be very difficult to operate.
Plastic matching

The instrumental color matching method is developed on the basis of visual color matching method. This method uses spectrophotometer and other measuring instruments to replace the functions of human eyes and brain. The trial process of color ratio is carried out by computer simulation without the actual mixing of plastic coloring. The operator only needs to measure the reflectivity, that is, its standard value, and select the pigment used to match the color. By adjusting the concentration of color matching pigments, the measurement system is consistent with the standard conversion value. If the paint chosen by the operator is reasonable, the system will output a formula in the form of mass fraction, and then convert the percentage formula into the mass ratio.
Plastic color matching plate

At present, manual color matching is the main form of daily life. Mechanical color matching for the shop, because the mechanical match, the computer picture and the actual sample there is a certain chromatic aberration.

Select an electric screwdriver

As the saying goes, “if a worker wants to do good, he must first use his tools.” Although a small electric screwdriver is very common, there are certain knowledge about how to choose and use it correctly.

First figure 1

1, according to the need to distinguish home use or professional use, most electric screwdriver is designed for professional personnel, in the selection and purchase should distinguish between the professional and the general household electric screwdriver. Generally, the electrical batch difference between the professional and the general family is on the power, and the professional use of electrical batch power is larger to ease the workload of the professional. Generally, the electrical batch is small because of the smaller work and the workload is relatively small, so the input power of the electric batch is not very large.
2. The outer packing of the electric batch should be clear and undamaged. The plastic box is strong. The buckle of the plastic box should be strong and durable.
3, the appearance of the electric batch should be color and lustre even, the surface of the plastic parts have no obvious shadow silk and dent, no scratch or bump marks, the assembly dislocation between the shell parts is less than 0.5mm, the aluminum casting coating is smooth and beautiful and no defect, the surface of the whole machine should have no oil pollution and stains. When holding the hand, the handle of the switch should be smooth. The length of the cable should not be less than 2 meters in length.
4. The nameplate parameters of the electric batch should be consistent with that of the CCC certificate. Detailed instructions and contact details should be given to the manufacturer and manufacturer. The nameplate or certificate should have a batch number that can be traced back to the product.
5, hold the electric screwdriver with the hand, connect the power supply and operate the switch frequently, make the tool start frequently, and observe the reliability of the switch function of the electric screwdriver switch. At the same time, it was observed whether the TV and fluorescent lamps on the scene were abnormal. In order to confirm whether the electric screwdriver is equipped with an effective radio interference suppressor.
6, the electric driver is operated for one minute, and the hand is held by hand. The hand should not feel any abnormal tremor and observe the change spark. The commutation spark should not exceed 3/2 level. When running, there should be no normal noise.

Definition function and working principle of antenna

The definition of antenna
We know that communications, radar, navigation, radio, television and other radio devices are all transmission of information through radio waves, which require radiation and reception of radio waves. In radio equipment, a device for radiating and receiving radio waves is called an antenna. Antennas provide the necessary coupling between transmitter and receiver and medium for transmitting radio waves. Antennas, like transmitters and receivers, are also an important part of radio equipment.

The function of the antenna

The antenna radiates radio waves and receives radio waves. However, the transmitter is not a radio wave sent through the feeder to the antenna. The receiving antenna can not send the radio wave directly through the feeder into the receiver, and the energy conversion process must be passed. Next, we take the radio communication equipment as an example to analyze the transmission process of the signal, and then illustrate the energy conversion function of the antenna.

Working principle
When a conductor passes through a high frequency current, an electric field and a magnetic field will be generated in the surrounding space. According to the distribution characteristics of electromagnetic field in space, it can be divided into near area, middle area and far area. Let R be the distance from the conductor to the space, and the region at a is called the near area. The electromagnetic field in the area is closely related to the current and voltage in the conductor. The region of the B is called a far zone. In this area, the electromagnetic field can leave the conductor to spread to the space. Its change is lagging behind the current and voltage on the conductor for a period of time. At this time, the electromagnetic wave propagating out has no direct connection with the current and voltage on the wire, and the electromagnetic field in this region is called the radiation field. It must be pointed out that when the length of the wire is much smaller than the wavelength of wavelength, the radiation is very weak; when the length of the conductor is L increases to the length of the conductor, the current on the wire will increase greatly, and thus the stronger radiation can be formed.

Hardware stamping die processing needs to pay attention to 5 major issues

Metal stamping die processing is very common, but many of our friends engaged in metal stamping die processing are not very aware of what needs to pay attention to, think as long as there is no accident, in fact, this view is not correct, as a professional hardware stamping die processing personnel, we need to understand. Which hardware stamping die processing matters needing attention? Below Xiaobian to introduce to you.
Hardware stamping die processing needs to pay attention to:
1, the processing technology of metal stamping die can not be too complicated, but the content should be detailed and processed.
2, if the metal stamping die needs to be processed in combination, the process should be clearly expressed.
Metal stamping die display
3, when the insert needs to be processed separately, we should pay attention to the precision of the processing. It needs to be particularly noted. The installation of the process needs to meet the requirements of the separate processing standard.
4, hardware stamping die processing key or difficult place, we also need to emphasize, prevent some people ignore.
5, the spring in the metal stamping die processing is the most nest damage, so we must pay attention to its service life when choosing the die spring.
Therefore, we need to pay more attention to how to prevent accidents.

Six exercises from a customer perspective

Practice does not solve the problem, nor does it create business or cost reduction, but it can improve our ability to look at the right point of view and act in the right way.

An old friend of mine recently asked me, “what do you think is the way of marketing?” I have to think well of this question. The best answer I can give is that marketing is a capability to see problems through a customer perspective.

Unfortunately, it is impossible to see problems from the perspective of customers. If we want to see what our customers see, we must achieve that: we do not understand what they do not understand. And this is impossible. We always know more about our company and products than our customers. We can’t turn what we really know into something that we don’t understand.

Luckily, marketing is a bit like golf. Even tiger Woods could never score 18 shots in one shot. But we don’t have to get a full mark to win. We only need to get a better score than our competitors. Then, from the perspective of the customer, how can we improve our score?

What we need to do is to keep learning and practicing repeatedly like tiger Woods. Here are six exercises I described in the book “detail marketing: everything you do not know in marketing” (TheMarketingYouNeverKnew). These exercises do not solve the problem, nor can we start business, or cut costs, but it can improve our ability to look at the right point of view and act in the right way.

Live all the time in reality

Recently, I gave a marketing research report to a fast consumer company boss. Sitting in his office, I saw that the company’s products were placed in a beautiful glass display cabinet. The lights and mirrors in the cabinet were extremely hazy, creating a wonderful effect. I pointed out to him that every time he passed through the beautiful glass cabinet with his eyes, he was deceiving himself. Because consumers actually see a variety of products every day, and his company’s products only occupy 15% of the space on the shelves. Moreover, some competitors’ products look similar to those of him. I propose that he accept my suggestion, replace this beautiful glass cabinet with a common common shelf in a supermarket, and put all the competitors’ products on the shelf besides placing their own products. He really listened to my advice. Now, whenever he looks up, what he sees is real reality. I think this will greatly change his judgment of the problem. Of course, if his salesman knows that the boss is a person who is willing to understand the real situation and grasp the actual situation, there will be nothing wrong with it.

Talk to old customers

Listen carefully to their conversation and find out the real reasons why these old customers leave you. These old customers are not satisfied with you, so you can’t expect them to make pleasant words to make you comfortable and warm. But it’s just that they can tell you a lot of things. Like journalists, they should talk to a politician’s ex-wife rather than his current wife. For example, credit card companies MBNA asked its senior manager to call former customers and ask them to come back and continue to receive MBNA services. There is no doubt that this method can make people learn more about business than the research reports painted by market research companies.

Hire important personnel from customers

Many companies have already done this. In fact, IBM hired a former major client, Gerstner, to become LouGerstner’s CEO before saving herself. At that time, almost everyone in IBM company, virtually everyone in the computer industry, thought that IBM needed immediate separation to find a way to survive. Gerstner knows little about computers, or he doesn’t know anything about computers. However, he used to be a IBM customer, so he knew – not to know that the main problem of IBM was the lack of collaboration between the regional divisions and the products, which could not be solved by split. On the contrary, it needs to strengthen the integration and collaboration of all parts of the company. Why does no one in IBM think about this? Because of course, when you are not a client, it is hard for you to think from a customer’s point of view.

Let your clients manage to help you

Maybe you should ask your potential customers to review your new advertisements and let them approve or reject your advertising ideas. Or when you have meetings with marketing personnel and advertising companies, ask these customers to attend meetings and express their opinions. The brand manager of a famous European company who produced laundry detergent once told me: “we always ask customers’ opinions and reactions before advertising.” But the question is why do we need to get customers’ opinions to be screened through your mind? You know, you are likely to be ignorant.

Imagine if advertising agencies knew in advance that housewives would like or dislike their advertisements, would this affect their advertising production? Yes, I think it is。 They try to make advertisements that attract housewives instead of attracting marketing managers, because the former is the one who buys detergent, and the latter is only the person who buys advertising.

Interpretation of corrosion resistant magnetic driving pump for engineering plastics

Among the many products of the plastic pump, the corrosion resistant magnetic drive pump is one of the most important parts.
The plastic pump is made of plastic material, and it is made of different materials according to the chemical nature of customers. It is acid and alkali resistant. No leakage is a major highlight of the magnetic driven centrifugal pump. There is a larger gap between the internal and external magnetic rotor. The thickness is not more than 8mm when the non metal isolator is adopted; the thickness is not more than 5mm when the metal isolator is used; the wall thickness of the isolation sleeve is larger, the possibility of the isolation sleeve to be worn is smaller; the gap between the isolation sleeve and the outer magnetic rotor is also larger (most (most). Up to 1.5mm), the operation is reliable, because the shaft seal wear is less likely to rub the inner magnetic rotor and the isolating sleeve. The isolating suit, the disassembled side can be replaced in the field, the maintenance is convenient, the SiC bearing can be applied, the wear resistance is good and the service life is long!

Secondly, the non leakage magnetic drive pump is suitable for transporting flammable and explosive liquid because of its complete sealing effect. The medium can be protected from pollution, and it has overload protection when transmitting power. The use of magnetic pump is very extensive. The liquid includes water, oil, acid and alkali, emulsion, suspension emulsion and liquid metal. It can also transport liquid, gas mixture and liquid containing suspended solids. When selecting type, the parameters to be provided are: head, flow, medium name, temperature, concentration, power and viscosity.

The magnetic drive pump does not need independent lubrication and cooling water, reduces energy consumption, has small power consumption, high efficiency, and has damping and damping effect. It reduces the influence of motor vibration on the magnetic pump and the effect of cavitation vibration on the motor.

The working principle of the bubble vegetable cleaning machine

Vegetable cleaning is one of the essential processes in vegetable processing and vegetable production. At present, vegetable cleaning relies mainly on manual processing, and its mechanization procedure is very low. The existing vegetable washing machines have two types: vibration spray type and drum type. There are two cleaning pools in the vibratory spray vegetable cleaning machine. The vegetables are used in the vibratory cleaning pool for repeated movement, and the initial cleaning is carried out. Then the shower pool is sprinkled with clean water to complete the whole cleaning process.
The washing machine has large water consumption and has great damage to leafy vegetables. The main body of the drum type cleaning machine is a tilted metal mesh cylindrical revolving body. The center axis of the cylinder is equipped with a number of spray pipes of the nozzle. The vegetables are scoured by the jet flow at the same time as the cylinder rotates, so as to achieve the purpose of cleaning. The washing machine can only finish the cleaning of root vegetables such as potatoes and potatoes, and the damage to vegetables is large when it is washed. It can not be applied to the cleaning of leafy vegetables. Therefore, a new vegetable washing machine with ultrasonic and bubble as vegetable cleaning power was designed. Experiments show that the cleaning machine can effectively remove the contaminants on the surface of vegetables, and has little damage to vegetables.

In liquid containing many bubbles, the instantaneous pressure will be generated when the bubble collapses and springback is regenerated. When the collapsing bubbles are near the solid boundary of the over current, the high pressure and repeated action produced by the ceaselessly collapsing bubbles in the flow can destroy the surface of the solid, thus producing cavitation. The bubble ruptures near the vegetable surface, and the nearly spherical bubbles move along the jet to the rigid solid surface. As the submerged jet forms a thin layer of flow on the surface of the solid, the lateral flow of liquid flow between the surface of the bubble and the vegetable surface makes the liquid pressure of the bubble wall near the vegetable surface (called the near wall) at the far end (called the far wall), and the velocity of the centripetal movement is slower than that of the other parts. At the center of the bubble moving to the vegetable surface, the distance between the near wall and the vegetable surface is basically the same. In order to maintain the conservation of momentum (without considering the effect of liquid viscosity), the bubbles must be accelerated, the far wall is inward inward, near the near wall, and the near wall is penetrated to form a very high velocity microjet. This micro jet points to the surface of the vegetable. Bad and erosion ability is very strong.

Through calculation and measurement, it is found that when the wandering bubble collapses, the velocity of the micro jet near the solid wall can reach 70~180MPa. Such high dynamic pressure can completely remove the contaminants on the vegetable surface and shorten the cleaning time. Moreover, this is only the pressure of a micro jet on the surface of the vegetable. When the bubbles in the water continue to produce, increase, and disintegrate, the impact pressure of the bubble collapse continuously acts on the vegetable surface, effectively removing the contaminants on the vegetable surface.
