Bystronic Lenhardt introduces world’s first TPA

Bystronic Lenhardt Technology Center has delivered the world's first Horizontal Thermal Plastic Applicator. The machine has been developed for the application of highly viscous butyl to semiconductor thin-film substrates.

Centrotherm Photovoltaics is a Southern German based company which installed the TPA for high-precision butyl application to the edge of substrate glass prior to the lamination process.

The technology from Bystronic Lenhardt is based upon decades of experience in the design and construction of machines specifically for insulating glass production, where thermoplastic material is applied as a spacer between the glass plates.

In the solar industry, the TPA, which is available in a horizontal and vertical design, is used for the sealing of substrates of all types.

With the market launch of the horizontally operating TPA, Bystronic Lenhardt GmbH has introduced a machine that is the first of its kind in the world, which can actually work around the clock without any interruption.

The dosing pumps of the TPA apply the material exactly to a tenth of a millimetre. This way, the butyl protects the semiconductor effectively against moisture.

Product Manager Tobias Neff explains, "Two high-performance drum pumps ensure that the viscous sealant is always available for use."
