With the rapid development of blow-moulded products production industry, people have higher and higher requirements for the appearance and performance of blow-moulded products. In this paper, the deformation defects of blow moulded products are analyzed, and the solutions are put forward for the reference of the industry. Deformation of blow-moulded products refers to its external [...]
1 Overview The hollow blow molding machine is mainly used for producing various single-layer, double-layer, (double-layer) visible liquid level line blow molding hollow products such as bottles, pots, cans, barrels and small shaped parts, especially suitable for PVC, PE, Hollow blow molding of raw materials such as PC, PP, PS, and PA. The market outlook [...]
First, start the hollow blow molding machine 1) Turn the hollow blow molding machine clockwise, and turn the main power switch of the single-screw extruder from the horizontal state (OFF state) to the vertical state (ON state). 2) Start the extruder by pressing the green power button on the extruder control panel. 3) Press the [...]
Q: After the HDPE bottle is pulverized and dried, can it be directly blown? Do you want to add other materials such as LLDPE and other additives? Answer 1: Is it not good for injection molding? The surface of the film that is made out of the film is not light. Can blow, add some [...]
There are many products in the products used for hollow blow molding. Let's take a look at the raw materials it contains. It contains polyethylene, polyvinyl chloride, polypropylene, polystyrene, linear polyester, polycarbonate, polyamide, cellulose acetate and polyacetal resins. Among them, the consumption of high-density polyethylene is the first. It is widely used in the packaging [...]
According to relevant data, in recent years, the proportion of hollow blow molding machinery in the three major plastic presses (extrusion machinery, injection molding machinery, blow molding machinery) is relatively low. But the application of blow molding products in daily life does occupy a very large part. Therefore, the development space of the blow molding [...]
At present, in terms of the development of hollow blow molding in the market, its development in the market is not as good as it expected. Nowadays, the development in the market is relatively good, and it is also a hollow blow molding equipment. They exist in various industries in the market. In almost every [...]
At present, there are hundreds of blow molding machine manufacturers in China. Some blower manufacturers are already very large, while others are still in the family workshop. Regardless of the size, we must be consciously aware that the market for blow molding machines is constantly changing. How can we capture more in the fierce market [...]
The premise of the hollow blow molding process requires that the compression atmosphere of the parison in the inflated mold must be clean. The injection blow molding atmosphere pressure is 0.55 ~ 1MPa; the extrusion blow pressure is 0.2l ~ 0.62MPa, and the stretch blow pressure is often as high as 4MPa. In the plastic [...]
Plastic pallets are available in the following four ways: The first type: injection molding. The plastic tray products produced by the injection molding method are flat, smooth, crisp, compact, and have a large degree of product design freedom. They are divided into double-sided integral plastic trays and double-sided assembled plastic trays. The double-sided integral tray [...]
