Raw edges a) Confirm whether the number of frames and clamping forceof the injection machine are sufficient b) 確認壓力是否過高 1) 如果唔飽和樣品仍有毛刺, 表示合模不好或故障破損. 2) If the mold clamping is not good and the size is too …

injection molding conditions is the important thing for workshop owner to master. Injection molding is an industry with a wide range of knowledge, technology and practice. Plastic raw materials, toners, nozzle materials, 模具, 注塑機, peripheral equipment, fixtures, sprays, various auxiliary materials and packaging materials are used in the injection molding production process, which brings a lot of work to the management …

In the injection molding process of plastics, thermoplastics, due to the volume change caused by crystallization, strong internal stress, large residual stress frozen in the plastic part, strong molecular orientation and other factors, so compared with thermoset plastics, the shrinkage rate is larger. The shrinkage rate is wide and the directionality is obvious. 另外, the shrinkage after molding, annealing or humidity …

The screw fracture temperature is also related, but it is rare, almost all of the screw itself is of poor toughness, or the screw has been used for a long time, refurbish the screw! The injection molding materials are rough. 例如, adding GF [glass fiber] to the injection molding materials is the most expensive screw and machine! This injection molding material has poor …

不同類型嘅鋼用作塑料模具, 並且它們的化學成分和機械性能不同, 所以製造工藝路線係唔同噶; 同樣地, 不同類型嘅塑料模具鋼使用不同嘅熱處理工藝. 本節主要介紹塑料模具嘅製造工藝路線同熱處理工藝嘅特點.   解釋 …

The effect of back pressure on injection molding is very important, and it directly affects the filling of the melt and the quality of the plastic parts.   (1) Proper back pressure can improve the quality of products ①It can compact the melt in the barrel, increase the density, and improve the injection volume, product weight and dimensional stability;   ②The …

To do a good job in the management and prevention of china injection molding machine failures, it is necessary to grasp the causes of china injection molding machine failures, accumulate information and data about frequent failures and typical failures, carry out failure analysis, pay attention to the study of failure rules and failure mechanisms, and strengthen daily maintenance and inspections. …

1. Preparations before starting the china injection molding machine 1. Wear the safety protective clothing prescribed by the workshop before starting production. 2. Clean up the environment around the equipment, and don’t store anything unrelated to production. 3. Clean up the debris inside and outside the workbench and equipment, wipe the injection seat guide rail and the tie rod of …

注塑機嘅注塑部分總是存在問題, 如何解決? 1. Cannot shoot glue Approach: 1) 噴嘴被異物堵塞. 檢查噴嘴是否堵塞, 清潔或更換噴嘴. 2) 膠水噴嘴破損. 拆卸法蘭，檢查膠水噴嘴是否破損, and replace …

When using an injection molding machine, the possible failures of the hydraulic system of the injection molding machine are diverse. It is the result of a combination of many factors, and the dispersion is relatively large. 因此, when performing fault diagnosis, it is necessary to analyze the factors that cause the fault one by one, pay attention to their internal …

There are two templates on the injection molding machine, one is not moving, called the fixed template; the other can be moved, called the moving template. The mold is fixed on the two templates by screws and pressing plates respectively. 当模具打開時, the movable template of the injection molding machine moves, thereby driving the mold to open. …
