Future development trend of plastic mould Market
With the rapid development of plastics industry in recent years, the injection mold manufacturing industry has a completely new mode. The production efficiency of the mold industry has been greatly improved, which has a huge impact on the manufacturing industry. Due to the organic combination of online and offline manufacturing of injection mold manufacturing industry, the traditional manufacturing industry has been developing rapidly. In the information age, this advantage has been brought into full play.
In recent years, small and accurate injection mold design and manufacturing technology has received widespread attention in recent years. Micro injection molding technology has great potential for development and development. This technology is usually used in medical, telecommunications, computer, aviation, aerospace and other sophisticated fields. As medical and electronic devices are becoming more and more miniaturized, people hope that they can be made smaller and more sophisticated.
Development of mould industry
Because of the complex shape and flexible design of the plastic parts, it has high requirements for the mold material, the design level and the processing equipment, and it is not easy for everyone to get involved. At present, there is still a big gap between China and foreign design and production level. There are three major bottlenecks in the development of mould industry: first, the research and development of plastic materials and injection molding technology is not enough; the two is that the molding enterprises need to accelerate the integration of resources and form industrial belts; and three, the level of mould processing equipment must be as soon as possible. Keep up, otherwise plastic mold development will be restricted.

n the industrial environment, such as LED lighting, city outdoor lighting project, lighthouse, cruise ship, aviation, industrial equipment, cable, sprinkler and so on, all the water-proof power connectors are needed. In the military field, due to strict application requirements, a large number of waterproof connectors are used, such as submarine connectors, submarine missile connectors, etc.
At present, there are many brands and kinds of waterproof power connectors on the market, but in real sense, the waterproof power connector with excellent sealing performance and safe and reliable quality is still relatively small on the market. The main criterion for evaluating the waterproofing performance of waterproofing power connectors is based on the IP protection level. The protection level of outdoor connector should reach IP67 at least. The protective level of connectors for underwater use should reach IP68. Different types of connectors are selected according to the time and depth of the connector underwater.
The common environmental performance indexes of waterproofing power connectors include temperature resistance, moisture resistance, salt fog resistance, vibration resistance and impact resistance.
(1) temperature resistance.
The highest working temperature of the connector is 200oC (except for high temperature special connector), the lowest temperature is -65oC. As the connector is working, the current generates heat at the contact point, resulting in temperature rise. Therefore, it is generally considered that the working temperature should be equal to the ambient temperature plus the contact temperature.
(2) dampness.
The intrusion of moisture has great influence on the insulation performance of the connector and is easy to corrode metal parts. The condition of constant humidity and heat test is 95% relative humidity (up to 98% by product specification) and temperature +40 + 20oC. The test time is at least 96h according to the product requirements. The alternating humid heat test is more severe.
3. Salt resistant fog.
When the connector works in the environment of moisture and salt, the electroplating of the metal structure and contact surface of the connector produces electrochemical corrosion, which affects the physical and electrical properties of the connector. The salt spray test is to hang the connector in the temperature controlled test box, and spray the compressed air with the prescribed concentration of Sodium Chloride Solution to form the salt fog atmosphere. The exposure time is specified by the product specification, at least 48h.
4. Vibration and shock resistance.
Vibration and shock resistance are the important properties of electrical connectors, especially in the special application environment, such as aviation and space, railway and highway transportation. It is an important indicator of the robustness and electrical contact reliability of electrical connectors.
Other environmental performance.
In accordance with the requirements, the other environmental properties of the electrical connector are also sealed (air leakage, liquid pressure), liquid impregnation (resistance to specific liquids) and low pressure.
The characteristics and cancellation of the US foreign trade company after its establishment
If we do not write off, we will do annual review every year. If we do not do the annual trial, we will get a fine. The longer the time, the more fines. One or two years later, the automatic cancellation was abnormal cancellation, which was winding up by the government. There will be a record of bad credit, such as being no longer a director of an American company for a period of time. Furthermore, visa applications, such as applications for us travel or business visas, are likely to be refused.
When the US company is registered to complete the normal operation and maintenance of the normal operation of the United States company, it will not produce an abnormal state and record if it is required to do the annual trial and tax in the prescribed time limit, but there will be a business or business change. To abandon the existence of US companies, it is necessary to cancel the closure of US companies in order to avoid fines and bad credit records.
U. S. companies do not use, can not write off? If not written off will have what impact? First no write off can be first, but also need to do on time and tax action, complete the survival procedures, maintain the normal state and good record of the United States company. Second, if you do not want to do annual audit and tax return, you will have to pay the government’s fines and bad records, which will affect the success rate of shareholders’ visas to the United States. Third, if we do not want to bear the punishment of the government, we need to cancel the procedure. What steps do we need to cancel when we cancel it?
First, it is necessary to complete the annual audit procedure in this year. If the company did not normally make the annual review, it would still have to pay all the fines imposed on the government.
Second, we need to clear up the accounts, complete the tax declaration, and pay the taxes paid to make up the tax.
The steps that American companies must take before they are written off can be summarized as follows:
1, the cancellation of the US company is best to be carried out within 3 months of the validity period of the company.
2, before the cancellation of the US company, the company’s account must be cancelled.
3, before the cancellation of the US company, the company’s debts should be paid out.
4. If a fine is imposed, a fine must be paid.
When these steps are completed, the government will allow the normal cancellation procedures of the US companies. If any step is not completed, it is not allowed to cancel.
The advantages and tax requirements of the Anglo American foreign trade company
The popular choice of foreign companies is Britain, the United States and other countries, but for some people, it is not very clear about the registration of Companies in the United States and Britain.
The registration of US companies will bring the following benefits to enterprises:
1. reasonable tax avoidance, reducing the financial and tax burden
All offshore jurisdictions stipulate to varying degrees the revenues and profits earned by the Off Shore Company, which are exempt from local taxes or at a very low tax rate (such as 1%). We can make good use of overseas companies to arrange tax properly and avoid tax in a reasonable and lawful way.
All foreign companies in our country have a policy of reducing or duty-free, using international transfer prices to distribute profits and expenses. If not in the United States, we can exempt from corporate income tax, company share tax and personal income tax.
2. to facilitate international trade and avoid tariff barriers
Today, if an enterprise wants to export its products to the United States, it needs to apply for quotas and go through a series of related procedures, which costs one to two times more. And if the enterprise has an overseas Off Shore Company, from the enterprise to the Off Shore Company export products, and then the Off Shore Company exports to the United States, you can save the trouble of handling related procedures, greatly save your time, indirectly say is to save your cost, and can also bypass the switch tax barriers, get duty-free treatment, Make you successful in circumvent export quota restrictions. The amount of your trade is greatly increased.

Thinking of foreign customers positioning
1. reverse thinking on the rising cost of manufacturing in China
What is the challenge facing China at present? The first is that China’s cost is rising, in addition to the weakness of the traditional European and American markets, and the growing competition in emerging markets, such as Latin America, the Middle East, or the rest of Asia.
The next thing I say may be strange, from the buyer’s point of view, I think the rising cost of manufacturing in China is a good thing, because the rising cost will make the sellers think about how to improve the efficiency. Why do you say that?
For example, when I was drinking two cups of wine with my Chinese supplier ten years ago, I would ask you what your life goal is, make money as many ways as possible, buy a house and make a fortune after making money.
The situation is different now. If you want to survive, you have to become a more professional supplier and improve your competitiveness, so the rise in cost will let you think about how to improve your efficiency. My suggestion is obvious, that is, let the cost fall and the quality go up.
2. determine the target buyer!
I would like to tell you something valuable today, telling people to attract the right buyers and make the buyers feel satisfied, but it sounds easy. The reality is that many of our Chinese suppliers don’t have such a plan, such as two thousand or three thousand Chinese factories, and they don’t even have a plan to define them. It is the target buyer, how to make the buyer satisfied.
At the end of this point, it’s important that some of the ready made and customized products are also an important point. Some sellers may be good at repeating products, doing low cost products, and some suppliers are good at making customized products, so these two are different. We need to see what kind of company can determine your target customers.
3. seeking truth from facts, not exaggerating
At the same time, when our buyer goes to your page, the buyer will know what product you are doing and what your expertise is to do. Make sure that your product company’s information or sales personnel have certain language knowledge.
We need to know that it is almost impossible to find a Portuguese speaking person in Dongguan, so we can consider working with partners from overseas countries to find their own sales partners in the overseas market to help you solve the problem.
The first thing I want to say is that I know most Chinese people are very frank, because my family also has many Chinese people, and I love this country. But we find that many Chinese companies do not seem to do very well on a web site, such as the size of the company, the situation of the customer, the history of the company, the ownership of the company and so on. Sometimes the company wants to highlight itself in the market competition, and the size of the company, the longer the history, the ownership of the XX, and so on, and so on. It’s not a good thing. We have to be honest. If your company’s history is not so long, it doesn’t matter, because some customers are willing to look for such a business.
4. provide clear materials to let buyers know your business.
If you are a production enterprise, it’s impossible for you to put up a photo of your own factory, because your competitors can do it, so be more prepared, especially your quality control manual, which is not enough for ISO, who can spend thousands of dollars on a ISO certificate. So we don’t have to have a few specification books and a quality control manual. If you can submit more information, I think we can prove what a good production company is.
5. optimizes the website
Then let’s look at what a good web design is. I think the website is very important. First of all, we need to know the idea of your target customer, for example, the Brazilian mentality, what he thinks in his mind is different from what the Americans think.
6. strengthen communication with customers to make buyers trust you
Communication is so important, when an employee sends an email, he will know if the mail is satisfied with these standards, such as your attachments are added, it is wrong, the translation needs to be translated into English, the point is clear, and the time zone differences between China and the United States, so take the opportunity to hold the opportunity Do not make mistakes in the process of sending mail

Take all the products as art works
Zhang Hui has been unwittingly working for 3 years in the work of industrial chiller and laser chiller. In the past, he worked for work and was reluctant to contact the machinery related work and equipment, and felt dirty and tired. However, the geese began to break into my inherent knowledge from entering this enterprise. In the workshop for a month, 6S site management makes the whole workshop look clean and tidy, not so dirty and dirty as imagined.

After the end of the internship, the boss gave me the company’s previous Alibaba shop, starting from the various models that began to collect products, studying the features and functions of each product, taking pictures of the products at various angles to see the photos at a glance. Later, in order to increase some beauty, PS learned all kinds of backgrounds. In addition to more intuitive display of oil cooler, industrial water chiller, laser chiller, electrical cabinet air conditioning and electric cabinet heat exchanger.
The results of self-study are not bad, haha ha.
As the time of work grows longer and more, it is becoming more and more discovered that the equipment really is like a piece of art. After the design of the designer’s professional principles, it has become the cooling of the hydraulic press, the cooling of the hydraulic system, the cooling of the lubrication system, the CNC processing center, the precision of all kinds of precision. Machine tool, injection machine, laser cutting machine, engraving machine, wire cutting machine, medical equipment, welding machine cooling, medium frequency furnace, electric cabinet and power cooling, transformer cooling, engine bench cooling and so on.
The amount of consultation has gradually become more and more, the product is also used in all walks of life equipment, when their efforts gradually become visible, the sense of achievement arises spontaneously. I hope our partners will be more and more spacious on the road to Internet commerce.
My entrepreneurial experience is from the rural youth to the counterattack
Someone asked me why I want to start a business. In fact, I personally feel that starting a business is not necessarily linked to money. For me, starting a business is just a way of life.
After graduating from secondary school, I entered the big family and went into the work of our nail factory. I went to the factory for three years. And I went into the factory to sell it to the factory. At that time, I wanted to sell it to our boss and told me to sell it. The boss said you can’t do this in public. It was a big blow to me at that time. I had a sleepless night. I had the idea of starting my own business. Then I had the idea of producing machinery and equipment, and I had a drawing machine of my own. This may be related to my family. When I was a child, my parents always said I didn’t give up. I was very disgusted with the evaluation of me. Maybe they were out of kindness to motivate me, but I decided from that time that I had to make some achievements to show them. In fact, I was very hard on the work and learning, but I felt it was just a sense. I feel that I have paid a lot of sweat, but can not take out a little achievement of special grievance, I remember once heard a word “ambitious talent will have achievements” and I was also with such an impulsive and self righteous mentality into my entrepreneurial journey. Wire drawing and drawing machine for the supporting equipment of professional production nail making machine
Starting a business is a very high risk. It can be said that the chances of success are very small. It also takes some good luck to start a business. Sometimes, although your efforts and your management measures are very thoughtful, there is no good luck with you. Love, but every time you encounter a problem, it will take you a lot of time, and I am a bad luck player. The problem is like rain.
It is not difficult to start a business, but when it comes to starting a business, we always hear complaints like this. Some people say I do not have the cost, some people say I do not understand anything, and some say I do not know what to do, and some say I have a wife and children at a loss how to do, you listen to it, it is difficult to talk about, there are few methods.
This is the best and the worst of times. In this era, the country is full of business opportunities. This era is also an era of money supremacy. In front of money, what feelings, laws, morals, all stand behind. In such an age, some people hate the rich and complain about the uneven distribution of society.
I think this thinking is very terrible. What are your enemies? No society is absolutely fair. Besides, this is a social reality. Can you change it? You can’t change it. Well, if you can’t change, don’t complain about anything. Look at yourself and change yourself.
