Hollow blow molding manufacturers will tell you about "hollow blow molding" What is hollow blow molding? In hollow blow molding manufacturers In the production workshop, the plastic parison is usually placed in the mold cavity, blown with compressed air to make it close to the wall of the cavity, and the hollow thin-walled product can be obtained after cooling and shaping. Most thermoplastics can be blow molded. In fact, hollow blow molding manufacturers Usually high-density polyethylene HDPE and polypropylene PP are blow molding materials that are widely used. We also mentioned in the previous articles that hollow blow molding is generally divided into extrusion blow molding, injection blow molding, and stretch blow molding. If you are interested, you can read the previous articles. We sorted out the whole process, which can be summarized as follows: plasticizing—extruding the parison—closing the mold, clamping the upper and lower ends of the parison—blowing compressed air, pasting the mold—holding pressure, cooling, shaping—— Deflate, take out the product-remove the flash residue. What are the advantages of hollow blow molding? In general, hollow, double-walled structures absorb and dissipate impact energy. The design is also relatively flexible, which enables the product to have high functionality and low production cost. Processing technology can change the thickness of the parison. Hollow blow molding manufacturers During processing, the thickness of the product can be changed arbitrarily without improving the mold. Low-pressure molding (mold stress is much smaller than injection molding), which improves dimensional stability, chemical corrosion resistance and high temperature performance. Assembly diversity: self-tapping screws, molded inserts, rivets and expansion fasteners. The mold is simple, the cost is not high, and the processing cycle is short. Of course, hollow blow molding manufacturers Inexpensive sample molds can also be produced quickly. We will continue to chat later, if you are interested, please continue to pay attention.
