Enlarging the aperture of the nozzle Nylons 612 products produced in the processing of poor release of die: 1. The improper control of the mould temperature makes the shrinkage of each part unevenly caused by the uneven force of the mold. 2. The residual stress in the product is large, which makes it difficult to die. The way to solve this problem: 1. Reduce the pressure of injection and pressure protection; 2, reducing injection and holding time 3, increase or reduce the temperature of the material. 4, improve or reduce the mold temperature. 5, check the die draft To solve the warping deformation of nylon 612 products. The mechanism of production is that the internal stress of the products is too large and the shrinkage of the products is not uniform. The internal stress of the product is too large: 1. Reduce injection pressure, reduce injection time, reduce pressure pressure, reduce pressure time 2, improve the temperature of the material and improve the temperature of the mould. Unevenly contractive products: 1. Reduce the temperature of the material, reduce the temperature of the mold and improve the cooling time. 2, improve the injection pressure, improve the injection time, increase the pressure of pressure protection, and increase the time of pressure protection. Other reasons: 1, the location of the gate is not reasonable 2. The setting of the wall thickness of the products is not reasonable 3. The structure of the die is not reasonable Ptyalism produce nylon 612 nozzle products processing solutions when: This is a problem that is often encountered in the production of nylon. The main solution: 1. After enlarging the glue. 2, reduce the temperature of the material and reduce the temperature of the nozzle. 3. The drying of raw materials is not sufficient. 4, add slingshot nozzle The poor plasticization solution produced during the processing of nylon 612 products: 1. Low back pressure 2. The temperature of the barrel is too low 3. The screw speed is too fast 4. The forming period is too short Physical property table PMMA The use of colorful chassis and fully transparent chassis. Whether it's a full - transparent case and a colorful chassis, it's a computer case, which is used for computer assembly. It is only that the material of this case is different from the traditional case. The two problems that affect the development of the colorful chassis and the fully transparent chassis: one is the price problem. The price of this kind of machine is higher than that of the traditional computer case. In fact, the cost of this case is really higher than those of the traditional computer cases, which is impossible. If you want to make fun of the beautiful effects that the chassis turns to be colorful, it can only take more money. Of course, some businesses are too high. As for the market rumors, there are a number of super low - priced, transparent and transparent chassis, which is not really a real, colorful and transparent chassis. It has one or two transparent boards on the traditional computer box, not all transparent, and the price is much lower. The other is the problem of heat dissipation. It is said that the colourful chassis and transparent chassis materials are all organic glass acrylic plates. And the organic glass is actually a kind of plastic, the heat dissipation is not very good indeed. But it doesn't mean there's no way to solve it. Exhaust fan。 From the actual effect, the effect of heat dissipation is good. What are the advantages of the acrylic bathtub The formal name of the acrylic bathtub is the glass fiber reinforced plastic bathtub (acryl is the homophone of the English ACRYLIC). The surface material is methyl methyl methyl methyl ester, the reverse side is coated with glass fiber, and is coated with special resin. The whole bathtub should have a uniform color, smooth surface, no layers, bubbles and so on. The thickness of the surface is generally above 3 mm, and it is firmly combined with glass fiber and is not stripped. The heat transfer of the acrylic bathtub is slow, so the heat preservation is good, and the contact body surface has no "ice cold" feeling. Compared with cast iron or steel bath tub, it has a feeling of "warm and soft" and does not touch the body. Because of the good reprocessing property of the acrylic, the luxury massage bathtub is not its own. The bottom of the acrylic bathtub should be filled with yellow sand cement paste at the bottom of the installation, which can not be vacated or only on a few supporting points, so as to avoid breaking. We should prevent sharp objects against friction in use, soft cloth and detergent wipe light application when cleaning, do not use 100 clean cloth. Once a cleaning hair, with a soft cloth with toothpaste wipe, can restore luster. Transparent furniture has been in a non mainstream way of existence to the love of the avant-garde to provide a variety of personality options. However, a few piles of glass furniture burst, people on the transparent furniture was still yearn for fear. "Frailty" has become the pronoun of transparent furniture. How can we be transparent and transparent? See how the alternative and transparent furniture, which is quietly selling on the market, is how hard it comes to us!
