The angular corners of the profile frames are flocked by an electrostatic method. In the process of flocked profiles, the profiles are stretched out on a carousel-shaped processing line. The profiles are then sequentially passed through a spray booth, a climate cabin with a flocking device, and a supply station. The profiles are subsequently dried. The resulting Flocked profiles can be used as window or door frames.
Flocked profiles have two major advantages. Firstly, the flocking tape does not take up much space - it requires only two square meters. Furthermore, it does not limit the cross-linking time, thus increasing extrusion speed. The use of flocking tape makes the process more efficient and saves time and energy. Moreover, it provides consistent floc quality throughout the profile. Furthermore, a single strip of flocked tape is much smaller than two square meters.
In the automobile industry, flocked EA-TPE profiles have a number of advantages over EPDM rubber. These types of materials are cheaper to produce and have a higher degree of precision and durability. Also, flocked EA-TPE profiles are more resistant to long-term air aging than EPDM rubber. These benefits make Flocked profiles an attractive option for a variety of applications. Aside from automotive applications, flocking is a great option for belt line seals and glass run channels.
Flocked rubber profiles are made through a process that involves using a flocking tape that has a desired flock width. The base of the flocked tape contains an olefinic compound compatible with the polymer present in the profile rubber. Once the flocking tape is bonded to the rubber profile, the flocked tape is cut to the desired width. Once the process is complete, the Flocked profiles are ready to be installed.
Once the extruded profile is ready, the flocking process can begin. The first step is the vulcanization of the profile, where the extruded material is heated to 110C. Then, adhesive is applied to the surface and the adhesive is allowed to cure for two to three minutes at 170C. This process is known as karussellformig. Once this step is complete, the profile is ready to be placed in the final production line.
The flocking process can be repeated as many times as desired. The process is highly automated and highly versatile. Many automotive companies have attempted to eliminate the use of flocking because of its unmatched performance. The process involves the application of short precision fibers with adhesive to the surface. These fibers are perpendicular to the surface, resulting in a velvet-like feeling. Rubber profiles are typically flocked with nylon or polyester fibers.
