Gerold公司推出了HMA系统，这个系统自动应用液体丁基来为进行光伏组件压延。具有代表性的是，这个程序应用于无框架的薄膜组件中。
这种边缘压延技术提高了产品的密封效果，因此能够提高产品的安全性，组件的性能和持久性。
GEROLD GmbH & Co. KG has debuted the HMA system, which automatically applies liquid butyl (hot-melt) for edge-sealing of PV modules. Typically, this process is performed on frameless thin-film modules.
Edge-sealing improves encapsulation properties, thus significantly improving product safety, module performance and durability, the company says. Edge-sealing is usually performed with butyl tape; however, liquid butyl application offers economical packing drums, less waste and improved product quality, according to the company. Furthermore, butyl ribbon acuity and repeat accuracy are improved.
The HMA system features a drum unloader from Nordson. Depending on system configuration, one or two dispensers are utilized and integrated with GEROLD equipment, thus ensuring repeat accurate edge-sealing with optimal ribbon application and high throughput.
