ASA film extrusion line

China GWELL is used as extruder manufacturer, ASA is made by copolymerization of styrene, acrylonitrile and acrylic rubber. Technically, ASA not only maintains the main characteristics of ABS, but also combines the advantages of acrylic weather resistance, has outstanding anti-aging properties, can achieve online thermal composite, uniform composite thickness, no color difference, high bonding strength, overcome the traditional In addition to the chromatic aberration problem of co-extruded ASA composite, it also saves the cost of raw materials, so that the application of the product can be extended to outdoor applications, such as the field of roof tiles, which has been widely used. The composite thickness is uniform, there is no color difference, and the bonding strength is high, which overcomes the color difference problem of traditional co-extrusion ASA composite and saves the cost of raw materials. The processing thickness range of ASA surface: 0.05-0.2mm, width 1500mm, uniform thickness, stable size, in addition, it is also used in outdoor decoration and so on.

ASA film extrusion line product application field

1. Automotive field: ASA will not gradually turn gray like the specially treated anti-aging ABS after a long time of wind erosion (many microscopic cracks and cavitation on the surface due to wind erosion or water flow). Typical applications of ASA are exterior parts such as exterior mirrors, radiator grilles, tailgates, lamp shades, etc. that are subjected to harsh conditions such as sun, rain, and strong wind. At present, it has gradually extended to motorcycle panels, camping cars, small boat hulls, surfboards and other fields.
2. Horticultural field: Horticultural field: GWELL as China Plastic Extruder manufacturer, ASA film extrusion line of ASA proved to be especially suitable for horticultural irrigation equipment and lawn mower casings, etc.
3. Electrical and electronic fields: It is preferentially used in the casing of durable equipment, such as all-weather casings such as sewing machines, telephones, kitchen equipment, and satellite antennas.
4. Construction field: ASA/PVC blends are used in roof siding and window materials. In this regard, there have been more than 10 years of practical application experience abroad.

ASA is a copolymerization of styrene, acrylonitrile, and acrylic rubber. Technically speaking, ASA not only maintains the main characteristics of ABS but also combines the advantages of acrylic weather resistance, so that the application of the product can be extended to outdoor use.
ASA film products are made of the high content of ASA rubber powder raw materials. The products have completely passed the 12,000-hour weather resistance test.
The color retention performance is many times higher than that of the current co-extruded materials on the market. The uniformity of ASA film is higher than that of co-extruded material, there is no color difference of thin spots, and no waste of scraps.
Therefore, the ASA film extrusion line has become a development trend at this stage.

Features of ASA film extrusion line produced by China GWELL

1. As China Plastic Extruder Supplier, GWELL adopts PLC and closed-loop control for the whole set of equipment, which can realize one-key acceleration and simple operation.
2. The special screw design of the extruder ensures that the melting of the raw plastic material, the color of the product is uniform, and the extrusion volume is high.
3. The full-automatic mold combined with the thickness gauge can more effectively fine-tune the melt thickness deviation in the transverse width of the die, and the thickness uniformity is guaranteed to be ±10 um.
4. China GWELL casting roll adopts the method of integral processing of inner runner to ensure that the temperature is controlled within ±1 degree, and the control accuracy of rolling surface is within ±10um to ensure more accurate casting film thickness.
5. The tension sensor and control system is used to ensure the tension control is ± 10um.
6. A complete set of servo motors and servo controllers make the equipment run more accurately.
7. The fully automatic cutting and rewinding machine have two functions: contact rewinding and gap rewinding. The winding tape has tension control, the adjustment range is 5-200N/M.

ASA film extrusion line product advantages

Because of its outstanding anti-aging properties, ASA film is used in the field of roofing tiles. It can realize on-line thermal lamination during the processing of roofing tiles, with uniform lamination thickness, no color difference and high bonding strength, which overcomes the traditional co-extrusion ASA lamination The existing color difference problem also saves the cost of raw materials. The processing thickness range of the ASA surface: 0.05-0.2mm, the width is 1500mm, the thickness is uniform, and the size is stable.
