Luo Baihui believes that to meet the ever-increasing performance requirements, it is still difficult to meet the application of new mold materials. Therefore, the die-casting mold is required to have high heat fatigue resistance, thermal conductivity wear resistance and corrosion resistance. At the same time, it also puts forward higher requirements on the comprehensive mechanical properties and Plastic mould manufacturers life of die-casting molds..

Pressure casting is to make the molten metal fill the mold cavity under high pressure and high speed and die-casting. , impact toughness, red hardness, good release properties, etc. Life expectancy. Therefore, the surface treatment technology of the Huangjiang die-casting mold is relatively high. It is repeatedly in contact with the hot metal during the working process.

With the rapid development of China’s automobile and motorcycle industry, the die-casting industry has ushered in a new era of development. Various surface treatment technologies must be applied to the surface treatment of die-casting molds to achieve high efficiency, high precision and high efficiency for die-casting molds. In various molds, the working conditions of the die-casting mold are more demanding.Surface treatment technology of die-casting mold needs to be improved

　　The surface treatment technology of die-casting mold needs to be improved

In the international market, industrialized countries are shifting to developing countries, especially Southeast Asian countries, due to increased labor costs. Its country is mainly engaged in the production of high-precision molds, and CNC molds with large labor input are relied on imports. Therefore, the potential of the medium and low-end molds in the international market is enormous. From the perspective of the development trend of machinery manufacturing technology, the proportion of high-efficiency beds in Chinese factories will increase year by year, and the demand for high-efficiency and advanced tools will increase rapidly.

For the current situation that the demand for advanced molds for beds is increasing, China’s tool industry must change its concept, vigorously develop the production of high-efficiency and advanced tools, pay attention to sales, and pay more attention to after-sales service, and strive to innovate to occupy more market share. From the perspective of reducing imports, the proportion of such high-end molds and hardware tools in the market will gradually increase. As long as the quality of China’s molds can be improved, the delivery time can be guaranteed, and the prospect of mold export is very optimistic. Seize new opportunities and strive to capture more market share. The mold industry is moving toward technological innovation, and technological upgrading is necessary. This is the most important condition for the rapid development of the industry and market demand. Although China’s mold industry has been a low-end product for a long time, it started late, but with the gradual transformation, new opportunities for the industry have emerged.

In addition, due to the increase in labor costs, the price advantage of medium and low-end molds will gradually be lost. China imports nearly $1 billion a year in molds, mostly precision, large, complex, and long-life molds. In recent years, China has imported nearly one billion US dollars of mold per year, most of which are precision, large, complex and long-life molds. The mold industry started late, but with the gradual transformation, new China injection molding suppliers opportunities for the industry have emerged. It is understood that during the ‘Twelfth Five-Year’ period, the overall trend of the mold market is stable and upward, but domestic molds must meet the needs of users in terms of quality and delivery time. With the transformation of China’s CNC molds and the continuous changes in industrial innovation, the market prospects of various branches in the industry are gradually becoming clear.. It is reported that the Chinese market currently has a large demand for medium and high-grade molds, especially in the home appliance, automobile and plastic products industries. The demand for mold standard parts is also large, but China currently has only a small amount of exports. In the future, China’s mold and CNC tool industry will also rank among the best in the world.The new era of CNC molds has come

Once the material of the mold is not good enough, it may also greatly reduce our service life to a certain extent for our entire use..

This is very important for our whole use. So, what issues do you need to pay attention to when shooting molds? Design and material are very important when shooting molds. Our The entire process can be made easier. This is now The most important problem in the production of injection molds. Only the design is reasonable and practical. We can’t just focus on the design work of injection mold manufacturing.Problems that need to be paid attention to when shooting injection molds

The problem that needs to be paid attention to in the injection mold manufacturing is that the mold manufacturing is a common Plastic Injection Molded Automotive Parts one in the mold manufacturing, which not only makes our use easier, but also brings great help to the current production and life. There are still many problems in shooting molds, and we need special attention to help us achieve easy use. In addition, the injection mold manufacturing now requires special attention to the material of the mold. Normal work

In recent years, the world-famous hot runner technology suppliers have entered the Chinese market in various ways, showing the huge development potential of China’s hot runner mold market. At the same time, this trend is also playing a huge role in promoting the rapid improvement of China’s mold industry technology. A large number of emerging private enterprises in China also recognize the unlimited business opportunities in this field and have established hot runner production enterprises. This is of great significance for reducing the use cost of hot runner technology and speeding up the application. However, in general, most of the technologies that local enterprises in China can provide are still relatively primitive.

The choice of Plastic mould manufacturers space is small, the quality is unstable, and the maintenance period is short, which often affects the trust of downstream enterprises in their products. Therefore, the development of national standards for hot runner components, the active production of inexpensive and high-quality components, and the promotion of hot runner technology are the key to the development of domestic hot runner molds. Unlike traditional molds, modern molds are not only complex in shape and structure, but also have higher technical requirements. It is obviously difficult to manufacture with traditional mold manufacturing methods. It is necessary to rely on modern science and technology and advanced manufacturing techniques to meet technical requirements. At present, the development of the whole industrial production is characterized by many varieties of products, fast update, and fierce market competition. In order to meet the urgent requirements of the market for short delivery time, high precision and low cost, the cavity mold will have the following development trends:

Increase the proportion of plastic molds: With the continuous improvement of the performance of plastic raw materials, the parts of various industries will be replaced by plastics, and the process of plastic substitution of wood will be further accelerated, and the proportion of plastic molds will increase. Second, increase the accumulation of molds and powder forging: due to the development of lightweight products such as automotive, vehicles and motors, such as aluminum-based steel, non-full density molding, polymer materials, composite materials, engineering ceramics, superhard material molding and processing . The adoption of new materials not only changes the structure and performance of the product, but also proves a fundamental change in the production process. Correspondingly, liquid (semi-solid) extrusion dies and powder forging dies have emerged. The manufacturing precision of these molds is high. Third, vigorously develop rapid manufacturing molds: At present, it is the era of multi-variety and small-batch production. On the one hand, the product life cycle is shortened, on the other hand, the varieties are updated quickly, which requires the mold production cycle to be as short as possible. Therefore, rapid prototyping molds will increasingly attract people’s attention and attention. Fourth, the increasing number of high-grade molds: one is used for nano-scale precision machining of automobiles, airplanes, precision machinery; the other is sub-micron (0.01μm) precision machining for disk and drum manufacturing; the third is for ultra-precision Nano-scale (0.001μm) precision machining of electronic devices. Further increase the gas-assisted mold and high-pressure injection molding mold. With the continuous improvement and development of the plastic molding process, in order to improve the injection quality, gas-assisted molds and high-pressure injection molding molds have also developed. Fifth, the increasingly high mold accuracy: 10 years ago, the precision mold is generally 5μm, now it has reached 2~3μm, and soon the 1μm mold will also be on the market. With the miniaturization of parts and the improvement of precision requirements, some molds are processed. Accuracy is required to be within 1 μm, which requires the development of super finishing. Sixth, the expansion of the application of hot runner technology: because the hot runner technology of the mold can improve the production efficiency and quality of the parts, and can greatly save the raw materials of the parts, therefore, the application of hot runner technology is developing faster in foreign countries, many plastics More than 50% of the molds produced by the mold factory use hot runner technology, even more than 80%, the effect is very obvious. Hot runners have also been used in production in China, and some companies have used 20% to 30%.

At present, the quality of CNC machining in China is affected by many factors, including machine tools and clamping factors, processing tool factors, processing technology factors, etc. It is also an important factor affecting the quality of CNC machining. The role of the mold to fix the position of the mold to determine the role of the mold fixed scene. The following plastic mold manufacturers give you a brief introduction, what are the main influencing factors of China’s mold CNC machining quality? 1 Machine tool and clamping factors Mold CNC machining machine is the place to ensure the precision of machining. It is an effective device to distinguish the production of parts.. Therefore, it is very important to choose a good tool., while independently researching and developing a variety of home products, and won a number of national invention patents. Once the mold processing tool is selected, the most direct hazard is that the mold data processing work cannot be operated correctly, resulting in unreasonable cutting position of the mold. Clamping is an important part of CNC machining.

Therefore, only the processing tool with excellent texture can improve the numerical control machining of the mold. If the machine tool and the clamping work are not handled well, the overall quality of the CNC machining will be reduced, the safety of the mold processing will be reduced, unnecessary resources will be wasted, and the overall quality and level of the mold processing will be reduced. The speed is slow, which affects the stability and safety of mold data processing quality. 2 Machining tool factors The tool directly participates in the mold making process.

The company specializes in all kinds of precision mold design, manufacturing, precision plastic molding, etc. Hengxingchang Mould Technology Co. Quality to meet people’s needs. 3 Processing technology factors Processing technology factors affect one of the key factors of CNC machining quality, traditional processing technology operation is relatively simple, but the accuracy is low, which will endanger the overall quality of CNC machining, the mold is not qualified, not To the national standards, it will not only increase the complexity of CNC machining technology, but also cause Plastic mould manufacturers a lot of waste of resources once and for all., Ltd. is a wholly-owned enterprise that integrates product development and design, mold manufacturing, injection molding, and oil screen printing. At present, the most common tool material is hard alloy. Compared with traditional tool materials, it has many advantages such as toughness, high hardness, high speed and high accuracy

718 plastic mold, the quenching temperature is different? Plastic mold quenching temperature below: plastic mold steel S136: 1025 degrees oil, air-cooled Plastic mould manufacturers plastic mold steel NAK80: pre-hardened, no quenching; mold steel 718: pre-hardened, no quenching;

Mold steel SKD61: 1030 degrees, oil, air-cooled; plastic mold SKD11: 1025 degrees, oil, air-cooled plastic mold steel hardness is not temperature: plastic mold steel S136 quenching and tempering hardness is HRC52-54; plastic mold steel NAK80 factory .

The hardness is HRC 40-42; the hardness of plastic mold steel 718 (IMPAX) is HRC 38; the hardness of plastic mold steel SKD61 after quenching is HRC 62-64; the hardness of plastic mold steel SKD11 after quenching is HRC 60-62

First, the advantages of the hot runner nozzle: (1) no residue in the gate is left on the product, and the trace at the gate is smooth; (2) the gate with a larger diameter can be used to accelerate the filling of the cavity, and Further reduce the injection pressure and reduce product deformation. (3) It can prevent the phenomenon of wire pulling and flowing when opening the mold; (4) When the screw of the injection molding machine is retracted, it can effectively prevent the material from sucking precision mold manufacturing back from the cavity; (5) It can be matched with the sequential control to reduce the weld line of the product. . Since the form of the hot nozzle directly determines the selection of the hot runner system and the design and manufacture of the mold, the hot runner system is often divided into an open hot runner system and a needle valve hot runner system.

Requirements: The parts require very clean, almost invisible pouring points and avoid subsequent processing as much as possible. The nozzles are typically bolted for easy replacement. The needle valve nozzle leaves only a similar mark to the ejector rod on the surface of the product and is an effective method for products with surface decoration. In addition, it can reduce the internal stress of the product, shorten the processing cycle and adapt to the processing of a variety of raw materials (including materials with high wear and heat sensitive materials). Nozzles with a torpedo core have the following advantages: 1. The temperature is easy to control and the polymer can be automatically torn off at the nozzle. 2, the torpedo core can form a good tearing effect on materials that are easy to produce wire drawing (such as PA, PC). A disadvantage of torpedo cores is that they cause shearing of the material. Shear-sensitive materials can be damaged by strong shearing at the toroidal gap between the torpedo core and the runner and the chamfer of the torpedo core.

If the part is made of a material that is difficult to machine, the chamfering of the torpedo core can result in an imprint. Colored polymers are particularly difficult to process because of the accumulation of toner. Regardless of whether the material is amorphous, crystalline or thermoplastic, all methods of injection have certain limitations on certain materials. Hot runner molds come in many different forms according to the nozzle structure. The types are similar, but the processing techniques and implementation methods of different manufacturers are very different, which determines the difference in quality and price of the hot runner system. Second, the hot runner core plugging treatment: (1) very careful use a thin wire to pull out the blockage of foreign matter to ensure that the ring core and gate can not be damaged (2) If the above method does not work, remove the mold Hot nozzle (3) Write the snap ring and the heating wire cover (4) Hold the rear end of the hot nozzle with the three-jaw chuck (5) Heat the nozzle to the injection temperature of the plastic (6) Remove the nozzle (7) Remove the liner The sleeve and the mouth core should not damage and damage the corresponding parts of the ring (8) If the foreign matter is blocked, please find out the specific reason, find out the method of cleaning the foreign object in the whole injection molding system and thoroughly clean it. Pay attention to the whole system. Do not assemble the system before cleaning it, otherwise it will be extremely easy to cause blockage again. (9) Assemble the hot nozzle with a torque wrench (10) Install the mold

What issues must I pay attention to when choosing the right mold factory?The choice of the mold factory is quite important. The industry has always said the same sentence: half of the success of a good mold factory. It can be seen that the importance of the mold factory is self-evident, so how can the mold factory be good? The plastic mold factory below tells everyone that we must pay attention to what kind of problems should we choose for the right mold factory? 1.

It is recommended that you select the mold factory to integrate the situation and characteristics of the respective factories. After an objective evaluation of the needs of the various parts of the company in terms of the positioning of the molds and products, and then make a reasonable choice, it may achieve satisfactory results. . 2, must not blindly, blindly believe in low purchase prices, as the saying goes: a penny and a share of goods, low prices are often hidden behind some traps that are not known to us, or shoddy Or cut corners, you must know that any mold factory he has to pay rent to pay for water and electricity to raise workers and make profits? 3, I must find a fully equipped mold factory, preferably Taiwan-funded or Hong Kong-funded, At the medium-sized and above mold factory, I once had a lesson in this aspect when I was doing the procurement. At that time, I chose a small domestic mold factory because of the price. The whole mold department of this factory has only a few dozen people, even the CNC. None, other mechanical equipment is not complete, and only a few of the equipment are also some old equipment.

Later, the result was that the molds were opened by them, but the tinkering was not energy-producing at the end. It hurt me and the colleagues in the engineering department to go through a few hardships with Plastic parts processing nothing. I myself because After developing this mold factory and deducting all the performance bonuses of the month, it is really a bad one! Plastic Mould Factory is a sole proprietorship enterprise integrating product development design, mold manufacturing, injection molding, and oil screen printing. The company specializes in all kinds of precision mold design, manufacturing, precision plastic molding, etc., while independently researching and developing a variety of home products, and won a number of national invention patents.

If your machine is custom, it means you will China injection molding suppliers need another part of the customization. However, this may take a while, depending on the complexity of the part and what material is made. However, if you already have a part of you made of plastic mold, then ordering a part of you and waiting for it to arrive is a simple matter. Plastic molds use a quick way to get the parts you need in the shortest time and are not expensive in price, you can afford them. Plastic molds are quick and easy, and most importantly, they are inexpensive, you can get plastic parts made at low cost as soon as possible, because you need them, plastic is notoriously easy to use and surprisingly durable.

The process of molding plastic molds is quite straightforward. The plastic pellets are fed into the injection chamber of the hopper injection molding machine. The reciprocating screw inside the injection chamber ensures that the body of the particle inflowing machine is stable and uniform. The granules then pass through a heating element to melt the plastic.

The widespread use of plastic injection molding is due to its ease of use to a large extent. In fact, plastics are inexpensive and can be manipulated to almost any shape and certainly not harmed. If you use plastic parts, just keep some extra parts on hand so that you don’t have to worry about partial failure and take time to produce. By taking this approach, you can already give the shape you need in a short time, which is the advantage of plastic molds, which can save a lot of time and money.
