Hollow blow molding machines are widely used in modern society. However, there are many molding methods for manufacturing plastic containers, such as blow molding, injection molding, rotational molding, compression molding, hot extrusion and cold compression molding. Among the many molding methods of plastic containers, blow molding and injection molding are the two most widely used and the largest production methods.
According to information, 80% to 90% of the hollow containers in the world are formed by hollow blow molding. The hollow blow molding technology uses air pressure to make the plasticized parison close to the inner wall of the mold. The production method of the parison is extrusion, that is, the plastic melt that is heated and plasticized is extruded from the gaps of the die cores of various shapes to form cylindrical parisons of various shapes. The extruded parison is suspended vertically by its own weight. The minimum wall thickness of hollow container products is specified due to their strength requirements, and the early hollow blow molding machine equipment lacks a parison wall thickness control system. In order to make the thinnest part of the product meet the minimum wall thickness requirement, other parts of the product must be thickened accordingly. , resulting in material waste.
In order to save cost, shorten product cooling time, and speed up product production cycle, a more economical approach is to control the parison wall thickness. For example, the 501 wide-mouth barrel, the net weight of the product produced by the ordinary hollow blow molding machine is 3.5kg to meet the minimum wall thickness requirement, while using the parison controller, the net weight of the product can fully meet the minimum wall thickness requirement of 2.4kg, saving 20% of raw materials. %~30%, and the thickness of the products produced is uniform.
Meper machine is one of the largest blow molding machine production bases in the world; a company specializing in the design, manufacture and sales of blow molding equipment; its main business covers blow molding machinery, related auxiliary equipment, mold production and plastic raw material agency Wait. The blow molding machines and other products introduced by the company are leading products in the industry.
