TCTech Launches Embossing Production Cell

[Stockholm, Sweden, September 8, 2010.] TCTech, a global supplier of intelligent plastic nanostructures, today announced the launch of a new hot embossing production cell.

TCTech today launches the TCP1000 system, a hot embossing production cell utilising TCTech’s innovative and patented thermal cyclic pressing technology. It has been designed to meet the demand of fabrication of thin large-area light guide plates (LGPs), as well as optical lenses, such as Fresnel lenses, and lens arrays.

The system enables embossing of lenses in sizes up to 890x500 mm, or 40’’, with an area to thickness aspect ratio of up to 1:1000. The system can be equipped with an automated substrate handling system, giving a total cycle-time of less than 3 minutes.

Normally, light guide plates are fabricated by injection moulding, although some other technologies have "seen the light" recently, such as hot embossing. However, injection moulding has its difficulties when it comes to large-area LGPs, while conventional hot embossing has its bottlenecks of limited embossing area and, above all, a long heating and cooling time, resulting in cycle times well above 10 minutes.

By contrast, Thermal Cyclic Pressing can be used to fabricate at least 40’’ LGPs, with no warpage, unrivalled pattern replication, and radically shorter cycle times.

Thermal Cyclic Technologies is all about heating low mass. As opposed to injection moulding and hot embossing that needs to heat a big tool (high mass), Thermal Cyclic Technologies heat only the very surface of the tool, hence the temperature at the tool surface can be cycled from room temperature to 300 degrees and back to room temperatures in just seconds. This is possible due to a range of innovative and patented technologies and methods, such as special designed inductive heated tools, active cooling, and a unique material stack.
