Blow molding (Blow Molding) is to form a cylindrical parison (Parison) by extrusion or injection, insert it into the cavity, blow air inwards to inflate, and then cool and solidify into a hollow product of a special shape.
One: Supply raw resin to the extruder. The resin supplied to the extruder is melted by the frictional heat of the screw and the surrounding temperature, and fed into the Die/Head of the extruder.
Two: The Die/Head outlet of the extruder is cylindrical, and the cylindrical extrusion is extruded from this outlet. This cylindrical extrusion is called a parison.
Three: Die/Head generally consists of 2 divided molds. The divided left and right molds have cavities that resemble the shape of the molded product, which are called cavities.
Four: After the parison is extruded to a suitable length at the Die outlet, put the parison into two separate cavities.
Five: Blow compressed air into the parison put into the cavity, so that the parison is inflated into the same shape as the cavity.
Six: After inflating the shape of the cavity, it is cooled in this state.
Seven: After the parison blown in the cavity is cooled to near normal temperature to make it solidify, the cavity is opened to take out the product.
Eight: Remove the unnecessary parts that stick to the product to complete the product molding.
