How to evaluate the quality of the hollow blow molding machine screw? Like other things, the standard of evaluating the screw is gradually clear and perfect with the deepening of the understanding of the extrusion process. For the analysis of extrusion system, the screw should be evaluated in the following aspects:
(1) plasticizing quality;
A screw must be in line with the production of product quality requirements, the so-called conform to the quality requirements is that the products should have physical and chemical, mechanical and electrical properties meet the requirements; with quality meet the requirements of the table, such as can satisfy the needs of users on the bubble, crystal, dyeing dispersion uniformity etc.;
The so-called yield refers to the guarantee of plasticizing quality under the premise, through to the head of the output or extrusion. A good screw should have higher plasticizing capacity.
(three) unit consumption
The so-called unit consumption refers to the energy consumed per kilogram of plastic extrusion. The greater the value, the more energy it needs to express the same weight of plastic, which means the more power consumed
The so-called screw flexibility refers to the screw on the processing of different plastics, matching different head and different products adaptability. Adaptability is often accompanied by a reduction in plastic efficiency.
(five) the difficulty of manufacturing
A good screw must also be easy to manufacture with low cost.
