Extrusion Die Head
Blown Film Extrusion is one of the processes to produce plastic film products such as food packaging film, industrial film, agricultural film, medical film, etc. The main polymers materials are LDPE, HDPE, PP, PE. The Extruder Blown Film Die Head is the core component which is called the "HEART" of the Plastic Film Blowing Machine. The main function of Die Head is to distribute the melted polymer evenly so that the thickness measured around the circumference of the tube being produced is uniform. It is the key factor to ensure a quality film.
Extruder Filter
Extruder Filter is an essential component in the Plastic Film Blowing Machine which is called the cleaner. It protects the flow channel from damage by the dusty and filter the contaminants out as well. Depends on the different materials and extruders, customers are able to choose different types of filters to meet their requirements. Filter is allocated between the Extruder and the Extrusion Die Head. In order to fit the different types of feeding system and adjust the layout of equipment, it is available to install extra adapter, connector and joint for Filter. Furthermore, Filter increases friction drag of the bleeding material to bring back pressure and make the material mix well.
Rotary Die Head
With the change of marketing trends and shortage of manpower, the use of Extrusion Die Head has become a new choice in recent years. Considering the product quality and material cost, the Rotary Die Head brings the new business opportunity to the extrusion market. Rotary Die Head is mainly to increase the average of film thickness and ensure the flatness of film when winding. In order to maintain the average of film thickness, Rotary Die Head keeps rotating with the same speed. Besides, the Rotary Die Head distributes the uneven variations uniformly in order to upgrade the evenness of film and to reduce the ratio of thickness tolerance to the minimum. Without the rotation, the film will wrap unevenly and roll irregularly which causes the uneven thickness of film then lead to the gauge bands on the process of Blown Film Winder. Comparing fixed type die heads, the Rotary Die Head is the best option if your products require precision film thickness.
Blown Film Bubble Cage / Stabilizer
Blown Film Extrusion Machine is a process that extrudes the molten polymer through Blown Film Die Head to process the plastic film. If the bubble tube is unstable when it first comes out from the Die Head, it needs a support to maintain its stability to prevent it from transforming. Therefore, Blown Film Bubble Cage / Stabilizer play important characters here to stabilize and reinforce the blown film bubble tube while blowing. As the cooling system runs well around the circumference of the bubble tube, the Bubble Cage / Stabilizer maintains the stability of the bubble tube over Die Head and Air Ring. It prevents the bubble tube from losing stability and offers higher quality of film which shows the importance of Bubble Cage / Stabilizer.
