A plastic blow molding process is the most common method for producing hollow products using thermoplastic materials. Plastic blow molding is done by using a range of production methods such as injection, extrusion, and advanced blow molding processes. The main section of a plastic blowing machinery are the hopper, an externally-heated feed barrel, a reciprocal screw, and the head and die assembly. Resin, usually in form of plastic pallet is fed to the feed barrel from the hopper. This hopper, maybe filled manually or automatically. As resin enters the barrel, it is moved forward by the rotating screw. The resin starts to melt, as it is driven forward due to both the frictional force generated by the rotating screw and the heat from the heating bands that are attached to the feed barrel. The melted resin built up in pressure as it is compressed and confined at the end of the barrel. To control the pressure, the rotating screw is moved backward. Once the perfect amount of resin is available, the screw is then hydraulically forced forward. This rapidly pushes the plastic melt through the head and die assembly to form partisan.

Author: MULAN -Plastic Molding ManufacturerBurst of plastic products is a quality problem that often occurs in injection molded parts processing manufacturers. This nature is very serious. The main reason is how it is formed. When the black material is burst, customers generally suspect whether too much nozzle material is added. Because the water inlet material is a cause of bursting. There is another kind that bursts with a light touch. That position is mainly the bonding line, that is, the design of the plastic injection point is not in place when designing the plastic mold, and the welding line is made at the top of the perforated hole.It is also the thinner part on the outside. Especially in the production of ABS material, it is easy to break. Experienced design engineers will first review the glue point, and through the glue point, drive the weld line to a position where no burst will occur.After the injection molding staff of the injection mold processing factory left the post, it took more than 20 minutes. When they returned to work, they did not shoot off the waste rubber that had been in the barrel for too long and caused the rubber to deteriorate. If it is produced directly, it will also cause bursting. In this case, it will be more difficult to analyze the quality.
