Innovative Dosing Solutions for Photovoltaic Production
Increase Process Reliability – Lower Costs
ViscoTec offers specialized dosing solutions for all production steps that work with adhesives, sealants and metal pastes. Such a system significantly increases process reliability, while also lowering costs - thereby ultimately leading to a significant increase in production efficiency.
For manufacturing silicon wafers, the ignots need to be glued onto carrier plates so that they can be finely sawn. The most commonly used adhesives for this are two-component adhesives, which must be applied absolutely free of air bubbles. With the ViscoMT series of emptying units, ViscoTreat-Inline degassing and the ViscoDuo-V two-component system, ViscoTec can provide a complete system for this production stage that guarantees both bubble-free product feed as well as application of a constant, precise mixture of two-component adhesive.
Wafers are metallized with aluminium and silver paste using screen-printing systems. These must be continuously supplied with abrasive and highly viscous paste. For the small containers predominantly used in these applications, ViscoTec offers the ViscoMT-D, a version of this emptying system developed specifically for such silk screening systems, which can be easily integrated as a feed unit into the existing system control technology.
Since PV modules are exposed to extreme weather conditions, and must accordingly satisfy stringent demands on quality, perfect dosing results during production are directly proportional to the long-term success of the manufacturer's business. The most commonly used media for gluing module parts and casting connection sockets are two-component adhesives and potting compounds. Special material properties such as high viscosity and filler content place very high demands on dosing systems. The endless-piston principle of ViscoTec dosing pumps has been developed specifically for such applications. ViscoTec dosing systems can be easily integrated into various processes, thus ensuring high quality bonding and potting in automated production lines.
