PET bottle blow molding machine
2020年11月13日German WEIMA Machine Company demonstrated the latest results of two-step blow molding equipment at the Milan Plastics Exhibition on February 14-18, 2006, which is characterized by two primary and secondary blow molding machines.
This equipment is suitable for economical blow molding of engineering thermoplastics such as ABS, PA, PBT, PC, POM, PPA, LCP, especially reinforced glass fiber.
The method is to start large waste blocks or produce large volumes of leftover materials.
In the two-step blow molding, the material to be blown is pre-blown into about 40mm fine particles in the WLK-type consolidated single-axis main blow molding machine, and then further blow-molded into about 3 by the NZ-type subsequent secondary blow molding machine. ~10mm end pellets, which are especially described for secondary blow molding of pre-blow molding materials. In order to prevent defects in blow molding, it is necessary to continue to feed the crusher appropriately, and these requirements are generally difficult to ensure through manual operations.
Once the feed is excessive, it will generally cause uneven blow molding, shake, and water bottle blow molding machine at https://www.dianyamold.com/ accompanied by high-level noise. The result is that the material accumulates or the material being destroyed due to conflict causes its heat to be weakened.
In addition, the higher sensitivity of disturbing data, and the generally higher blade wear that results in frequent replacement blades remain to be observed. In comparison, the two-step blow molding can make the main blow molding machine non-continuous feeding, where the hopper exerts the effect of a buffer.
The meaning of optimizing the entire production process with this method of feeding is serious, because those operators no longer need to discontinuously operate the blow molding machine, and then enable them to be busy with other operations.
After the control of a stop switch, the pre-blown particles are now superbly added to the NZ type secondary blow molding machine.
The placement of the two blow molding machines can be selected as one above the other or one behind the other.
The secondary blow molding machine operates according to the operating principle of the cutting machine, and is designed for pre-blowing particles. Compared with the general blow molding machine, the second generation blow molding machine has a much smaller volume and only needs to rely on less driving energy of the whole machine. Because of its uniform feeding and working at a speed of approximately 450min-1, there has been no problem.
When such a blow molding machine is used for the second destruction of pre-blow molding materials, the noise level generated is much lower than that of one-step processing with the same speed (n=450-500min-1).
