Plastic HDPE extrusion blow molding machine 5L for plastic model

Introduction

In blow molding, hollow plastic parts are being formed through a manufacturing process that is generally categorized into three main methods, namely injection blow molding, extrusion blow molding and injection stretch blow molding. Basically, the extrusion blow molding starts with melting down the plastic and forming it into a parison—a rounded mass of molten material formed by rolling it immediately after being removed from the furnace, with its final form being a tube-like plastic that has a hole in one end that serves as a passage way for compressed air. This material is then clamped into a mold and then blown by air, of which pressure will push the plastic out in order to match the mold. Once it has cooled and hardened, the mold would open up to eject the part. In the case of injection and injection stretch blow molding, these processes use a preform, which is a piece that already has a form beforehand.

Now, many plastic manufacturers use this method for the obvious benefits it brings. However, there are also some drawbacks to it that we should be aware of to know whether it is best to employ for the betterment of all.

1. Control Unit: Japan Mitsubishi PLC programmable controller and Taiwan HITECH touch panel. English parameter process setting, state monitoring and products counting are convenient and intuitionistic. PLC automatic temperature control model.
