Happy Chinese New Year 2024

In the past, people pasted paper cutouts on windows facing south and north before the Spring Festival. Paper cutouts are colored lucky red, with beautiful and exaggerated patterns. They express hopes of a merry and prosperous life, in line with the Spring Festival theme. Spring couplets are paired phrases, typically seven Chinese characters each, written on red paper in black ink, and pasted on each side of a door frame. Sometimes a phrase of four or five characters is affixed to the top of the door frame as well. It's tradition across China to hold a lavish feast to celebrate the New Year. Chinese try very hard to make this family event, often traveling long distances. In Northern China a traditional dish for the feast is jiaozi. They are shaped like old Chinese ingots, symbolizing wealth. Southern Chinese eat niangao (sticky rice cake) on this special day, because niangao sounds like "yearly higher", symbolizing improvement.People set off firecrackers to celebrate the coming of the New Year, as well as to drive away evil. On the first day of the lunar New Year, Chinese wish each other good luck and happiness in the New Year. It is customary for the younger generation to visit their elders and wish them health and longevity. People who are unable to visit their friends or relatives send a WeChat red packet or a text message instead of paying a New Year's call. The red packet is a red envelope with money in it, which ranges from one to a few thousand Chinese yuan. Usually the red packet is given by adults and elderly to young children in New Year days. It was believed money in the red packet would ward off evil spirits and keep children healthy.Digital red packets have gone viral in recent years, and "grabbing red packets" has become an extremely popular game on WeChat.

Canton Fair 2023 comes to live again

Well-known as the Canton Fair, China Import and Export Fair has been held biannually in Guangzhou every spring and autumn since 1957. Regarded as the largest scale, the highest level, Canton Fair presents the most comprehensive exhibition covering the widest range of industries and sectors, as well as the richest products and commodities. The Canton Fair likes a golden business bridge, linking insightful overseas buyers with high-quality domestic exhibitors. During the past three years, the Canton Fair was severely impacted by the COVID-19 and had to hold only on "cloud". This year, free from the impact of COVID-19, Canton Fair 2023 YAOAN, one of the best plastic machinery manufacturer in China, will attend Canton Fair 2023, the first phase. Our booth number: 18.1 D01-02 We will bring our plastic sheet extrusion machine to attend this fair. Show time: 15 to 19, April, 2023

Why does PET sheet become brittle?

Why does PET sheet become brittle? A large part of PET sheet brittleness is caused by internal stress. There are many reasons for brittleness, including: Equipment problems (1) There are dead ends or obstructions in the barrel that tend to promote degradation of the molten material. (2)The plasticizing capacity of the machine is too small, and the plastic in the barrel is not plasticized enough; the plasticizing capacity of the machine is too large, and the plastic is subjected to heat and shear in the barrel for too long, which makes the plastic easy to age and the product brittle. (3) The injector is tilted or unbalanced, and the top trunk section is small or unreasonably distributed. Mold problem (1)If the gate is too small, adjust the gate size or increase the auxiliary gate. (2)If the diversion channel is too small or improperly configured, try to balance or increase the size of the diversion channel reasonably. (3) Abnormal injection cycle caused by poor mold structure. Technical level (1) Cylinder and nozzle temperature is too low, adjust. If the material is easily degraded, the cylinder and nozzle temperature should be increased. (2)Reduce the back pressure and speed of screw preform to make the material slightly loose and reduce the degradation of plastic due to shear overheating. (3) The mold temperature is too high, making it difficult to release the mold; the mold temperature is too low, making the plastic cool prematurely, fusing poorly and cracking easily, especially for high melting point plastics such as PET flakes. (4) The cavity core should have a proper demoulding slope. When the core is difficult to release, the cavity temperature should be increased and the cooling time should be shortened. When the cavity is difficult to release, the cavity temperature should be reduced and the cooling time extended. (5) minimize the use of metal inserts, such as brittle cold heat capacity of polystyrene plastic, not to insert injection molding. Raw material level (1) raw materials mixed with other impurities or inappropriate or excessive solvents or other additives. (2) Some plastics, such as PET flakes, are heated under humid conditions and undergo catalytic cracking reactions with water vapor, resulting in higher strain on the part. (3) Too many times of plastic recycling or too much recycled material content, or too long heating time in the barrel, can promote parts brittle cracking. (4) Bad quality of the plastic itself, such as large molecular weight distribution, rigid molecular chains and other structural inhomogeneities are too many components; or pollution caused by other plastics, bad additives, dust impurities, etc. It is also the cause of brittleness. Product design level (1) Products with sharp corners, notches or parts with large thickness differences are prone to stress cracking. (2) Product design is too thin or too much hollowing.
