Q:Types of blow molded products

Container consumption growth is presentod Xuanniu plastic container continues to expand, industrial consumption growth is mainly due to improvements in products by new technology, such as multi-layer parison extrusion, extrusion, biaxial non axisymmetric blow molding etc.. The application and performance requirements of some blow molded products are listed in table 2.

Q:Blow molding process conditions The purpose of the adjustment of technological conditions is that,

Using artificial experience to adjust the input parameters and repeat the process to ensure that all parts of the product reach the minimum wall thickness as much as possible to reduce the wall thickness of each part of the product.Analyze and compare the results of several process plans, and finally determine the optimized process parameters. Stretch blow molding, also known as biaxially oriented blow molding, is a method for forming a packaging container by mechanically stretching an parison in a high elastic state of a polymer and expanding radially (stretched) parison with compressed air. Stretch blow molding consists of one step and two steps.

Q:How much is the gas consumption per EPS molding machine per hour?

1000 automatic quantitative preforming machine, designed for packaging design, pre density accurate, convenient operation, uniform bead.

Q:What's the maximum size of the automatic packing machine?

It depends on the size of the product you need to pack,

Q:Carton packaging in the form of technology, including several major categories

Carton is a three-dimensional shape, it is composed of a number of components of the surface movement, accumulation, folding, surrounded by a multi-faceted form of body. The plane in the three-dimensional structure plays the role of dividing space in the space, cutting, rotating and folding the different parts of the face, and the resulting surface has different emotional expression. The relation of the display surface of the carton shows the connection of the surface, side, top and bottom,
