CompactMet vacuum evaporation metallizer

CompactMet vacuum evaporation metallizer –Flexibility and high throughput for three-dimensional parts

- High reliability
- High productivity and flexibility
- Consistently brilliant end product quality
- Small machine footprint


The Bühler Leybold Optics CompactMet is an economic, compact and ultra-fast batch-type aluminum evaporation machine for vacuum coating of three-dimensional parts such as automotive plastic head light and tail light reflectors. The machine’s patent pending concept delivers clear advantages for flexible large-scale production. The substrates are loaded onto two easily accessible rotating pylons on each of the machine’s two doors, each pylon having a usable length of 1500 mm and a diameter of 540 mm. This double-door design minimizes delays between batches, as one door’s pylons can be loaded and unloaded while the others are being processed, a feature which helps to maximize productivity. High reliability thanks to smart und robust design
The CompactMet is deployed in daily mass production in the automotive industry and has demonstrated unmatched reliability and productivity. Key components such as the vacuum pump set, evaporation system and the plasma-enhanced chemical vapor deposition (PECVD) station are designed for a 24/7 machine operation. Maintenance requirements have been kept to a minimum by the consistent implementation of a robust and smart machine design. Furthermore, all serviceable parts are easily accessed and simple to maintain, thus ensuring a high machine uptime.

Efficient processing for high productivity and flexibility
Besides the intuitive and state-of-the-art human-machine interface (HMI), the machine concept itself offers considerable benefits for industrial mass production applications. The double-door “clam shell” configuration with two substrate holders per door facilitates highly efficient processing. The balance between output per batch and cycle times allows maximum productivity while offering a high degree of flexibility. For example, in combination with the enhanced vacuum pumping system, this design enables cycle times of less than 7 min for the deposition of a highly reflective aluminum layer, plus protective top coat, onto a typical car-lamp reflector.

Consistent and perfect end product quality through reliable and innovative technology
Well-proven key components such as the high-rate thermal aluminum evaporator unit and the high-performance PECVD station, with its four MF-powered electrodes, ensure an excellent and consistent quality of the deposited aluminum and siloxane protective top-coat layers. Also, newly developed and innovative components like the high-performance cryo-coil, which offers a tremendous high-vacuum pumping capacity and ensures an optimum water-vapor partial pressure during processing, guarantee a solid system performance, which in turn maintains very high quality levels.

Compact design for space-saving deployment and fast repositioning
With an optimized footprint (approx. 30 m² in total) the CompactMet is mounted in a compact and easy-to-handle steel frame. This allows easy and fast installation of the system and also relocation, if necessary. Thus once installed, the CompactMet system occupies a minimum of floor space.
