Why is it difficult to demould blow molded products?
  • Blow molding, also known as hollow molding, is a manufacturing process for forming hollow plastic parts: it was initially used to form glass bottles. Generally speaking, there are three main methods of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding. The blow molding process begins by melting plastic and forming it into a parison, or in the case of injection and injection stretch blow molding (ISB) preforms). A parison is a tubular plastic piece w...
    • What are the exhaust forms of extrusion blow molding molds? What are their characteristics?
  • It is a mold that produces plastic profile products with continuous shapes, also called extrusion mold, extrusion molding head or die head.
    • What is rotational molding process
  • Rotational molding is indispensable for the formation of rotomolding products. The rotomolding mold is a thin-walled shell whose inner cavity shape matches the shape of the plastic product. In order to facilitate demoulding, one or more parting surfaces are provided at the largest cross-section of the product, and quick clamping fixtures such as C-shaped chucks are installed at the parting part to ensure that no material overflows during the molding process. After the end, the product can be qui...
