The pipe head is an important part in the making of the plastic pipe. It molds the melted plastic material into a certain pvc pipe making machine. The extrusion die design is very important for the quality of the final product and the efficiency of the process. The die generally consists of two components: the die body and the mandrel. The mandrel is the inner portion of the die that forms the inside of the pipe; the die body does the work of forming the outside of the pipe.
It is important for prolonging the service life of the die to maintain the pipe extrusion die appropriately. The routine cleaning and the check on the die could be useful to avoid clogs and blockage that could damage the quality of the finished products. It might also be worth taking note of the die for any signs of wear, as this can effect how the die will run. If you maintain the extrusion die, you can also get better utilization and pipe quality.
When selecting a die material for your plastic pipe making machine, heat resistance, longevity, and anti-corrosiveness should be some of the factors to take under consideration. One material is not like another and can influence the die's performance differently. For instance, extrusion dies made of stainless steel are often utilized because of its heat resistance and its resistance to wear. Select the correct material as per your production applications.
Even though maintained correctly, polyethylene pipe extrusion dies can still have things go wrong with the tool, sometimes resulting in poor product quality and/or decreased functionality. One such problem that occurs is non-uniform flow, which can lead to non-uniform wall thickness in the end product. This can result from a number of reasons including a bad die design or a restriction in the die. A further problem that arises is "die swell", a phenomenon causing irregular dimensions of the pipe, due to swelling of the plastic upon exiting the die. Through troubleshooting these simple problems and fixing them quickly you will help to minimize disruption and improve the flow of your pipe production.
Those skilled in the art have developed improvement in pipe extrusion die technology allowing the pvc pipe production machine to be made with less energy and increased speed. 1 novel technology is to adopt a CAD (computer aided design) software in order to get the dies with higher level complicated structure and better precision. This results in more freedom regarding the form and size of the end piece. Futher, it is possible to extend the working life of the die inject by providing application of advanced materials including ceramic coatings. The addition of these technologies to your production process can help you to increase productivity and the quality of pipes.
