Q:Make cell phone lens what mould material is best! ?: Use the S136 vacuum to make sure you're talking. Besides the quality of the material, the polishing process is also very heavy, the material will be burned with orange peel

Q:The effect of mould preheating and several methods of preheating: In order to protect the mould and improve the efficiency of the mould, it is necessary to keep the mould working in a certain temperature range as much as possible. If the mould no preheating, on the other hand, due to the mold temperature is low, it is easy to cause molding difficult, mucous membrane, the casting defects such as cracks, on the other hand, due to the mold temperature change is too big, hot and cold stress is very big, it is easy to mold damage, severe cases, may cause mould crack. Therefore, pre-heating is very important. According to the heating method, it can be divided into electric heating, natural (coal) gas heating and temperature heating. 1) electric heating: the heat tube is mainly heated by heat tube, which is clean and convenient to use. The drawback is that the thermal radiation is small. Die casting die is not adopted normally.

Q:The performance requirement of die steel: Wear resistance The most important factor in determining the life span of die is the wearability of die materials. The mold is subjected to considerable stress and friction at work, and it is required that the mould can maintain its dimension accuracy under intense friction. The wear and tear of the mould are mainly of mechanical wear, oxidation and wear and tear. In order to improve the wear resistance of steel, will be die steel with high hardness, and to ensure that the carbide in steel or other composition, morphology and distribution of hardening phase is quite reasonable. Serving for overloading, high-speed wear under the condition of the mold, the steel surface to form a thin and dense oxide film with good sex of adhesion, lubrication, reducing between die and workpiece stick bite, welding, melting and wear, and can reduce the mold surface oxidation caused by oxidation wear and tear. So the working conditions of the mould have a large effect on the wear and tear of steel. The test method of abrasion resistance can be used to measure the relative wear-resisting index, as a parameter of the resistance level of different chemical constituents and tissues. In order to present the life of the pre-burring height, it reflects the wear-resisting level of various kinds of steel. The test was based on Cr12MoV steel.

Q:The wall thickness of the die is affected by the plastic parts: Wall thickness is high, thin wall is not enough, The wall is not uniform, and the stress concentration is deformed The thin wall is easy to hold, fill insufficient, the process is difficult to adjust, poor high

Q:How many types of molds? Please help me out!: Die, forging die, stamping die, aluminum casting (casting) using the block, wax mold, plastic mold, metal mould, plastic forming with modeling profile (profile), pressure molding die, glass blowing blowing mould,... This is for use. Cold/hot mold; This is divided by temperature. There is steel die, aluminum die, hard alloy mold; There are wood, sand and wax models; With a plastic mould; This is part of the material that makes the mold. There is a one-off model, multiple sex dies; Permanent model This is from the service life. There are mechanical moulds, space moulds, plastic moulds, building dies, and... This is part of the industry. There can be other calls, there is no uniform rule.

Q:What is the difference between mould injection and blow molding?: Blow molding: also call hollow blow molding, a kind of development rapid plastic processing method. Thermoplastic resin by extrusion or injection molding of plastic parison tube, hot (or heated to softening state), put in split cavity, mold closing immediately after ventilation with compressed air within the parison, make plastic parison swell and clingy wall in the mold, the cooling mold release, the products have all kinds of hollow. Blown film manufacturing technology on the principle and hollow blow molding is very similar, but it does not use the mould, from the perspective of classification of plastics processing technology, molding process is usually included in the extrusion of blown film. The blow molding process was used in the production of low-density polyethylene small bottles during world war ii. In the late 1950s, with the development of high density polyethylene and the development of blowing and molding machine, blow molding technology was widely used. Hollow containers can be up to thousands of litres, some of which are computerized. It is suitable for the plastic polyethylene, polyvinyl chloride, polypropylene, polyester, etc., and the empty container is widely used as an industrial packaging container.

Q:Why does the mold exhaust, so where does the gas come from: Just add a little bit of the purpose of the exhaust: burn. The other ten is perfect.Plastic mold venting is not good, the gases in the cavity is compressed, produce a lot of pressure, this is the back pressure to prevent the molten plastic for normal rapid molding, make it difficult to injection molding. Once injection molding difficulty in this case, the researchers often adopt the method of improve the injection pressure of injection, this led to the pressure maintaining prolonged, molding cycle delay, the production efficiency is lower, injection molding machine energy consumption increases and so on. Even corrosive gases are sometimes fouled in the cavity, contaminating plastic molds, reducing the life of the molds and increasing the cost of plastic moulds.

Q:What are the advantages of using a hot runner?: Save plastics raw materials There is no production charge in the pure heat flow mold because there is no cold water. This is especially important for the expensive application of plastic. In fact, the world's leading manufacturers of hot water production have been developing rapidly in the world's expensive years of oil and plastics. Because the hot runner technology is an effective way to reduce the cost of materials. Reduce waste and improve product quality The plastic melt temperature is controlled accurately in the flow system during the process of hot runner mould forming. The plastic can flow in more uniform and uniform state, and the result is a uniform component. The parts of hot runner forming are good quality, the residual stress is low and the parts are small. So many of the high quality products in the market are made by hot runner mold. Many of the plastic parts in the DELL laptop, such as the familiar MOTOROLA phone and the HP printer, are made using hot stream molds.

Q:What is the difference between a mold and a handboard?: Hand, is simply the sample of the product, after your design drawings, design products generally can't be perfect, can't even use, direct production once the defective will be scrapped entirely, greatly waste of manpower and material resources and time. And hand in general, is one of the few samples, short production cycle, loss less manpower, quickly find out the shortage of the product design and improvement, provide sufficient basis for product production. Because of this, some places and call it "the first board", is the first sample products, that is, more image description of the meaning of the plank, and in Japan, hand and is called the "hand", its English name is "rapid prototype". Molds are a kind of production tool that can produce parts that have certain shapes and sizes. People also is usually said mold, such as TV sets, telephone shell, plastic buckets and other products, is the software into a mold cooling injection molding plastic heating. The steamed rice cooker is also made of a metal plate that is pressed into this shape. Everything is made out of molds. You can say that there is no production without molds

Q:How long is the life of die casting die?: A: die casting materials used in aluminum, zinc, magnesium, copper, die die core materials also have domestic 3 cr2w8v, 4 cr5mosiv, Japan imports of SKD61, DH - 31, DAC and so on, such as the United States have H11, H13, Sweden's 8407, 8418, etc., and W302, 2344 and so on various brands, production materials used and the mold core materials affect the service life of mould, even with the same kind of alloy and mold core material, affecting the service life of die and the structure of the product shape and so on, so can't general said that the service life of die mold how much, die from tens to hundreds of thousands of times. Aluminum: 120,000 models Copper: 20,000 times Magnesium: 200,000 modules Zinc: half a million Three: base, the product structure adds and reduce die life.
