Detailed introduction

Reliable extrusion molding manufacturers use the extruder to complete the functions of plastic transportation, compression, melting, plasticization and exhaust, pump the melt into the head, extrude the parison with appropriate thickness and diameter from the tubular head at a predetermined time according to the preset procedure, and hang it vertically in the cavity of the pre separated blow molding die installed directly below the head.


Reliable extrusion molding company, when the sagging parison reaches the predetermined length, immediately close the two halves of the mold for blow molding, use the closing force of the mold to cut and clamp the parison between the two halves of the mold, move it to another station after cutting, insert the blow pipe head from one end of the parison, and ensure that the blow pipe, parison and blow expansion mold cavity have the same central axis. Open the mold, take out the product, cut off the tailings for post-treatment or secondary cooling. The - secondary cooling is carried out in the forming mold to form the shape of the product. However, in order to improve the production efficiency, the - secondary cooling is often incomplete.


After the product is cooled to a certain degree and basically shaped, it is moved into the cooling die to continue secondary cooling. Adjust the opening, cool the blow molded products, and conduct a cooling shaping on the premise of maintaining a certain inflation pressure, so as to ensure that the cooling is carried out close to the mold.
