Blister machineWhat is the application principle of vacuum pump?
The vacuum pump of the blister machine is mainly used in the forming process of the blister. The heated and softened blister material is tightly attached to the blister abrasive tool by using the suction generated by the vacuum pump to form the product.
Selection of vacuum pump for suction molding machine: when selecting vacuum pump for suction molding machine, it is necessary to select vacuum pump according to specific process, mainly with the following two main parameters as reference:
What are the selection of blister machine
1: Vacuum degree of blister machine: The so-called vacuum degree is an expression of the degree of air rarefaction, usually in PaPaMillibarMba, mmHgmmHgAnd other units said that after the blister product is formed, the product bubbles are mostly due to the fact that the vacuum degree does not meet the requirements, which leads to the phenomenon of product defects. Relative to the product groove deep products, vacuum requirements are relatively high.

2: Blister flow rate: refers to the amount of fluid that flows through a closed pipe or an effective cross-section removed by a vacuum pump per unit time, commonly usedM3/H,L/S,L/MinHe said that vacuum flow is an important indicator of suction. When we choose a vacuum pump, we should pay attention to the specifications and thickness of the product to calculate how much air needs to be removed in one hour or one minute, so as to determine how much flow vacuum pump is needed.
