Choose Jilian Mold Chinese Pet Bottle Does Not Regret

Posted by nicolepreform on Jul 18, 2019 in News

The blowing of the Pet Preform is carried out between the glass transition temperature and the crystallization temperature, and is generally controlled between 90 and 120 degrees. In this interval, PET is in a highly elastic state, which is quickly blow molded, cooled and shaped to become a transparent bottle. In the one-step method, this temperature is determined by the length of the cooling time in the injection molding process, so it is necessary to connect the two injection-boiler positions.

In the blow molding process: stretching - one blowing - two blowing, the three movements are very short, but must be well coordinated, especially the first two steps determine the overall distribution of the material, the quality of the blowing. Therefore, it should be adjusted: stretching start timing, stretching speed, pre-blowing start and end timing, pre-blowing pressure, pre-blowing flow, etc., if possible, it is best to control the overall temperature distribution of the preform, bottle The temperature gradient of the inner and outer walls of the blank.

In the process of rapid blow molding and cooling, induced stress is generated in the bottle wall. For a carbonated beverage bottle, it is resistant to internal pressure and is beneficial, but for hot-filled bottles it is necessary to ensure that it is fully released above the glass transition temperature.

Choosing Jilian mold, we produce professional China Pet Bottle products, and also provide you with perfect after-sales service. I believe that choosing us is a choice you will not regret.

Advantages Of Hot-dip Galvanized DIN 603 Bolts

Posted by abyihui on Jul 17, 2019 in News

First, hot-dip galvanized DIN 603 bolt features
The hot-dip galvanized DIN 603 bolt is obtained by immersing the rust-removed steel in a zinc solution melted at about 500 ° C to adhere the zinc layer to the surface of the bolt to prevent corrosion. The galvanized layer is relatively strong. The galvanized layer is relatively strong. Cold galvanizing, relatively no heating, little galvanizing, galvanized parts are easy to fall off when exposed to moisture. The fundamental difference between hot-dip galvanizing and cold-galvanizing is: Hot-dip galvanizing, also known as hot dip galvanizing, melts the zinc ingot by high temperature, puts the auxiliary material, and then immerses the metal structural member in the galvanizing bath. The advantage of hot-dip galvanized DIN 603 bolt is that it has strong anti-corrosion ability. The hardness of the galvanized layer of the bolt is better. “Cold plating” means “electroplating”, that is, the zinc salt solution is electrolyzed, and the plating part is coated without heating. The amount of zinc is very small, and it is easy to fall off when it is wet. Hot-dip galvanizing is a chemical treatment and belongs to an electrochemical reaction. Cold galvanizing is a physical treatment, only a layer of zinc is applied on the surface, so… Hot galvanizing is the galvanization of the steel surface under hot dip conditions. It has strong adhesion and is not easy to fall off. Hot galvanizing Although the tube also shows rust, it can meet technical and sanitary requirements in a long period of time.

First of all, the difference in process is that hot-dip galvanizing is to remove the oil, pickle, dipping, drying and immersing in the melted zinc solution for a certain period of time.

Second, hot-dip galvanizing has the following advantages compared with electro-galvanizing

(1) It can produce a thick coating layer, and has both a pure zinc layer and an iron-zinc alloy layer, so the corrosion resistance is good;

(2) The production efficiency of hot-dip galvanizing is particularly high; the time for the parts staying in the galvanizing hot bath is short

(3) Compared with electro-galvanizing, hot-dip galvanizing has lower production costs and has less impact on the environment than electroplating;



The Price Of Small Elevators For Homes Use

Posted by otsealex on Jul 16, 2019 in News

The small-sized elevators are not the smallest and the cheaper. The price of Small Elevators For Homes depends on whether the construction cost of the hoistway, the equipment cost of the elevator, the installation and transportation costs, the maintenance and the warranty period. In addition, it is necessary to combine the daily use of electricity and maintenance costs to determine whether regular invoices will be provided. The price of the elevator is related to the brand, the height and the configuration. The price of different drive modes is different (there are three types of traction, hydraulic type, screw type). Generally speaking, 15 to 20 million domestically produced, or imported four-story small elevators are all included in the package. 10,000 to 30 tens of thousands, if the all-inclusive offer is tens of thousands to 100,000, personal advice does not consider installing elevators or climbing stairs safe, after all, home small elevators are still safe, comprehensive budget, like buying a car Take a look at the elevator in the physical store.

How To Improve The Problem Of Pet Preform Production

Posted by nicolepreform on Jul 11, 2019 in News

Pet Preform is a kind of plastic product processed by injection molding. It has impermeability and insulation. It is usually used for the storage and transportation of some important liquid objects. It is common to have a blood pumping body in a hospital.

PET preforms are the main raw material for many of our blow molded bottles. In fact, the quality of PET preforms will affect the production of blow molding products to a large extent. So what are the problems with PET preform production and how can it be improved? The professional manufacturer of PET preforms is briefly described below:

First of all, some of the current preform manufacturers are on the one hand to enhance the price advantage of products, and on the other hand to improve their own profits. Therefore, doping the secondary material in the preform production process has become the unspoken rule of many merchants. Although the secondary material is inexpensive, there are various problems. These secondary materials are often difficult to meet the standards in terms of hygiene and flow into food, beverage and other markets, which will seriously affect the safety of food packaging.

Secondary preforms also have an impact on the stability of the blow molded product. Therefore, strengthening supervision and avoiding the secondary material Liurun preform market is a key point to be solved. Secondly, the preforming is easier to standardize than the blow molding bottles of different shapes, and the development of standards is conducive to the development of the market. Accelerating more detailed standards development and implementing bottle label related issues is something we need to work hard for some time to come. For pet preforms, it’s actually about the whole of plastic bottles, so we should pay more attention to them.

DIN 603 Bolt Process Requirements

Posted by abyihui on Jul 10, 2019 in News

DIN 603 bolt raw materials and related technologies are lagging behind. An important reason for the poor quality of DIN 603 bolt products is the poor quality of raw materials and the backwardness of related technologies. For example, cold heading steel wire cold heading steel is mainly used to manufacture fasteners such as bolts, nuts, rivets and bolts. Its chemical composition and metallographic arrangement are relatively high. Now the annual demand for cold heading steel is about 1 million tons. In the meantime, the automobile industry demanded 100,000 tons. However, due to technical reasons, the domestically produced cold-rolled steel wire only needs 300,000 tons, and imports nearly 700,000 tons per year.

The DIN 603 bolt process and process equipment are of low level, and the DIN 603 bolts do not guarantee the consistency of product quality. The mechanical basic parts are generally batch and many products, and there are also many kinds of products and processing precision requirements. Therefore, the production process and equipment are required to be high and the capital is large. Foreign countries have chosen high-efficiency and high-precision special planes, production lines or flexible lines, and have completed high-efficiency automated production.

DIN 603 bolts are critical to the manufacture and inspection of equipment. Mechanical universal parts have high requirements for standard accuracy, functional reliability and interchangeability of each part. DIN 603 bolts only allow very few products to be out of tolerance, and It is checked out before the factory to remove the unqualified products. It is assumed that there is no high-precision and high-efficiency equipment, and it is difficult for the company to live and open in the fierce competition. At present, the key equipment of China’s parts and components production enterprises is mainly relying on imports, because the wear and tear of equipment is large, and the equipment demand is constantly updated and transformed. The imported equipment and spare parts are expensive, and it is necessary to speed up the handling of critical equipment if you want to speed up the operation.

DIN 603 bolt product development speed problem. China’s mechanical parts operations are far behind in terms of technological innovation and new product development, especially for SMEs, which lacks technical strength and talents, short funds and necessary equipment, and less information about technology and technology communication, resulting in long-term tracking. In the imitation stage, there are very few intellectual property rights. Now there are not many researches on the development of DIN 603 bolt products. There are few independent research and development efforts in the enterprise. This is a key issue for the continued development of the operation.

How Do Passenger Elevator Companies Seek New Developments?

Posted by OdsonDon on Jul 8, 2019 in News

Nowadays, the passenger elevator market is sluggish, but the market competition has not been relaxed due to the environmental downturn. As the cost of enterprises continues to rise, enterprises are facing transformation and upgrading, and multiple pressures are coming one after another. How should مصعد الركاب enterprises develop in a difficult situation? What?

The situation is grim, the innovation of enterprises is the way out

The economic environment, the downturn is already the norm. The industry is facing problems such as rising production costs, weak market demand, and an urgent need to upgrade the industrial structure. However, these problems are not solved in the short term, nor can they be solved by a field manufacturer’s terminal promotion. Although the situation is grim, there is no need for enterprises to be overly nervous and pessimistic. There are many excellent enterprises and businesses in the industry. Most of them have experienced difficult times. There is no internal chaos and no pain, and enterprises cannot grow up. At present, the Chinese economy is suffering, which means that the government’s macroeconomic regulation and control will gradually weaken. For some enterprises, if they still want to rely on policy dividends to grab the market, and not to be realistic, market-oriented and consumer-oriented, create value, I am afraid that it will be getting worse. Therefore, under this circumstance, enterprises should not be afraid of change. It is the most terrible thing. In the current market, it will change and win. Whether it is a product, a marketing model, or an internal organizational structure, only by following the rapid innovation and changes in the market can we ensure the long-term health of the company.

How to change? These three aspects are breakthroughs.

First, change from the consumer side. Many people feel that the Chinese market is weak and demand is relatively saturated. Without policies and government investment, how can the market improve? actually not. Entity chain stores are sluggish, but online promotions are booming. Moreover, the consumption potential of the Chinese market is far from being thoroughly explored. The reason why the current consumer market is not strong is that the consumer demand is not satisfied, and there is no good product suitable for oneself to let the user pay the bill. Therefore, to solve the consumption problem, the so-called supply-side reform must be opened up with the demand side reform. Strategic relationship.

Second, seize the turmoil of Internet reform. Over the past 20 years, the emergence and development of the Internet has brought about tremendous changes in the market. The Internet allows companies to understand user needs more directly and change the consumption habits of the market. Many companies stand out because they have grasped the pulse of the Internet. Of course, many companies have been eliminated because they are not adapted to this change. In the future, big data and cloud computing will play an increasingly important role in the market. For enterprises, they cannot wait for these forces to attack their own lives, and they cannot blame the market for changing too fast. If you want to win, you need to seize the turmoil, create change, and lead change in the new situation.

Finally, enhance the strength of corporate technology. There is uncertainty in the direction of science and technology development, but what is certain is that if enterprises can combine technology development, update their technical strength in real time, and combine with products, it will produce unimaginable benefits. What is most lacking in China’s industry is the differentiated products, products and new technologies. This will also be the direction for the entire industry to break through in the next five years or even longer.

The more fierce the market competition, the more the company has to sink its heart to do a good job, the so-called “wine is not afraid of the deep alley”, with good products still need to play a good sign, constantly improve the soft power of the enterprise, the hardware and software to grasp , will certainly have the opportunity to win in the market.
