In the same year, Cornell University in the United States also set up the CIMP research project, which was led by Professor ng of Chinese descent. The product was named C-MOLD

what is the injection molding process of Shanghai Qingpu hardware parts injection molding processing factory? At the same time, it will carry out important business development and establish production plans. Specifically, business development needs to fully define the supply chain and establish an initial order to support the launch of the product. In order to lay out the assembly line, determine the human resource demand, and establish the manufacturing technology facility scheme, all these require the establishment of production plans. When the mold is completed, the“ α” (initial) product production, testing and assembly. After that, the initial product goes through a series of tests to verify its performance level, implementation standards and user satisfaction. If the initial product is not satisfactory, the manufacturing process, relevant tools and detailed component design shall be adjusted appropriately. At the same time, the operators will make detailed plans for quality control and training

what is the injection molding process of Shanghai Qingpu hardware parts injection molding factory? The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the mold shape will be obtained or the corresponding waste will be removed. As small as the electronic connector and as large as the automobile instrument panel, the workpiece can be molded with a mold

ordinary injection molding does not require a particularly precise injection molding machine or specially designated materials. Generally, commonly used thermoplastics can be used for production. Therefore, ordinary injection molding processes are widely used in modern plastic industry. Injection molding if the wall thickness of the injection molded parts is uneven, the product will be deformed or shrunk. To solve this problem, it is best to suggest the customer to modify the product. If the product cannot be modified, the transition can only be made by reversing the C angle or R angle at the transition between thick and thin, which will reduce the stress problem of the plastic during flow and reduce the stress. The product will not be easy to deform. Of course, the thickness and thin can not be more than 60%, Otherwise, it must be thinned or thickened

classification of injection molds

(1) single parting surface injection molds

when opening the mold, the moving mold and the fixed mold are separated to take out the plastic parts, which is called single parting surface mold, also known as double plate mold. It is the simplest and most basic form of injection mold. It can be designed into single cavity injection mold or multi cavity injection mold according to needs. It is the most widely used injection mold. Efficient automatic equipment can play its role only when it is equipped with automatic production molds. The production and renewal of products are based on the manufacturing and renewal of molds

(2) double parting surface injection mold

the double parting surface injection mold has two parting surfaces. Compared with the single parting surface injection mold, the double parting surface injection mold adds a locally movable intermediate plate (also known as the movable gate plate, which is equipped with gates, flow channels and other parts and components required for the fixed mold) in the fixed mold part, so it is also called the three plate (moving template, intermediate plate, fixed template) injection mold, The total number may exceed 5000, and more than 90% of them still inherit the experience gained from the mutual teaching and learning of teachers and apprentices. I don't know why, but they still strive to accept orders, continuing the miracle of Taiwan's economy. But orders are getting fewer and fewer

injection mold processing is widely used nowadays. Recently, the plastic industry has received some questions from many friends in the same industry. The most reflected is that when the injection mold is processed, the damage of the mold is the biggest headache for the manufacturer. Let me share with you the causes of this problem. If the injection mold is processed for a long time and the maintenance is not done properly, it is very easy to be damaged, which is undoubtedly a great burden for the injection mold processing factory, because the cost of injection mold processing is very expensive

what is the injection molding process of Shanghai Qingpu hardware parts injection molding factory? It is commonly used for single cavity or multi cavity injection molds fed by point gate. When opening the mold, the intermediate plate is separated from the fixed mold by a certain distance on the guide column of the fixed mold, so as to take out the pouring system condensate between the two templates. The double parting surface injection mold has complex structure, high manufacturing cost and difficult parts processing. It is generally not used for the molding of large or extra large plastic products

the color masterbatch coloring method can be divided into two types: granular material and liquid material injection molding, which can be mixed into various colors, of which granular material is the most common. The use of color masterbatch can be realized by mixing plastic with color masterbatch, and the mixture or color masterbatch can be actually transported into the injection molding machine. The utility model has the advantages that the color is cheaper, the dust problem is reduced, the cost of raw materials is reduced, and the storage is convenient. The dry toner coloring method is the cheapest. Its disadvantage is that it is vacuuming and dirty when used. To ensure uniform and accurate color in the production process, bags or cartons of specific sizes can be used to load the correct amount of dry toner. Reduce costs Improperly planned cooling system will lengthen the molding time, add cost, and uneven cold cutting will further cause warping deformation of injection molded products

(3) injection mold with lateral parting and core pulling mechanism

when the plastic part has side holes or side recesses, it is necessary to use laterally movable core or slider for molding. After injection molding, the moving die first moves down for a certain distance, and then the inclined section of the bending pin fixed on the fixed template forces the slider to move outward. At the same time, the push rod of the demoulding mechanism pushes the push plate to make the plastic part take off from the core. The predictable matters that restrict the mold structure, such as the mold gate position and molding cycle, should be solved in advance or corresponding improvement measures should be taken as far as possible

the injection molding industry belongs to a low profit industry, which is obvious to all. In addition, the entry threshold of the injection molding industry is relatively low, and only a few injection molding machines can be used for production. This has led to the emergence of many family style workshop enterprises in the industry, which undoubtedly increases the competition in the industry and reduces the profits of the industry. How should the injection molding factory improve the profits of the enterprise in the future. At present, the profit of pure injection molding processing is getting lower and lower, especially for some products with large batches, but the final profit accounting is also relatively low, which makes the injection molding factory must change the existing development mode in order to obtain better development opportunities in the future

(4) injection mold with movable forming parts

due to some special structures of plastic parts, the injection mold is required to set movable forming parts, such as movable punch, movable concave die, movable insert, movable thread core or ring, which can be moved out of the mold together with the plastic parts during demoulding, and then separated from the plastic parts. In addition, the mold also has an impact on the cost of products. When the batch size is small, the cost of the mold will account for a large proportion of the cost of the parts. At this time, the mold with reasonable and simple structure should be used as far as possible to reduce the cost

with the increasingly strict requirements for product quality in the future, precision injection molding has become the future development direction. However, which workshop type injection molding enterprises can not master the precision injection molding technology and will be eliminated sooner or later, which also brings opportunities for the development of injection molding enterprises. For high-precision injection molding products, the injection molding processing fees must be higher than now, This will make a number of outstanding injection molding enterprises stand out in the future. At present, plastic injection molding products occupy about 30%-40% of the entire plastic product market. Their high-efficiency and high-quality molding methods are loved by many enterprises, and the precision of the plastic products produced is also higher than that produced by other molding methods. The injection molding shell is an important branch of the entire injection molding products

(5) automatic thread unloading injection mold

for plastic parts with threads, when it is required to automatically demould, a rotatable thread core or ring can be set on the mold, using the mold opening action or the rotating mechanism of the injection molding machine, or a special transmission device can be set to drive the thread core or ring to rotate, so as to remove the plastic parts. During the injection process, the metal insert is easy to deform and shift, so the mold composition and the design of the mold shape that is easy to maintain the metal insert should be fully considered

(6) runner less injection mold

runner less injection mold refers to the method of adiabatic heating through the convection channel to keep the plastic between the nozzle and the mold cavity of the injection molding machine in a molten state, so that there is no pour system condensate when the mold is opened to take out the plastic parts. The former is called adiabatic runner injection mold, and the latter is called hot runner injection mold. It shall be confirmed whether the metal inserts need preheating or drying treatment. The purpose is to ensure product quality and forming stability

(7) right angle injection molds

right angle injection molds are only applicable to angle injection molding machines. What is different from other injection molds is that the feeding direction of these molds is perpendicular to the opening and closing direction during molding. The main runner is set on both sides of the parting surface of the moving and fixed molds, and its cross-sectional area is usually unchanged, which is different from the molds used in other injection molding machines. In order to prevent the wear and deformation of the injection molding machine nozzle and the inlet end of the main runner, replaceable runner inserts can be set at the end of the main runner

(8) injection mold with demoulding mechanism on the fixed mold

in most injection molds, the demoulding device is installed on the side of the moving mold, which is conducive to the work of the ejector in the mold opening and closing system of the injection molding machine. In actual production, because some plastic parts are limited by the shape, it is better to leave the plastic parts on the fixed mold side for forming, which makes the plastic parts come out of the mold, so it is necessary to set a demoulding mechanism on the fixed mold side

the temperature of the injection mold, the crystallization temperature and speed of different plastic particles are different, and the product appearance, deformation, size, plastic mold, etc. have different requirements, which makes the mold temperature control different when different plastics and product requirements are used. The injection pressure of molten plastic, the plastic is faced with great resistance in the process of filling the mold cavity, which makes the injection pressure directly determine the size, weight, density and appearance of the product

classification of injection molds

(1) single parting surface injection molds

when opening the mold, the moving mold and the fixed mold are separated to take out the plastic parts, which is called single parting surface mold, also known as double plate mold. It is the simplest and most basic form of injection mold. It can be designed into single cavity injection mold or multi cavity injection mold according to needs. It is the most widely used injection mold. The formula for calculating the cooling time should be 100% correct in all cases
