AluMet 1800V

The Bühler Leybold Optics AluMet 1800V is a highly economic, high-throughput, batch-type thermal evaporation machine for thin-film vacuum-coating of three-dimensional parts. Its double-door “clam-shell” configuration allows highly productive processing with each door holding six planetary pylons to carry the substrates. Each single pylon has a load capacity of up to 35 kg, is effectively 1500 mm long and has a usable diameter of 540 mm. The double-door design enables extremely efficient operation, as each door can be easily loaded and unloaded independently while the other is still processing.

High productivity from a generous load capacity and short cycle times

The intuitive state-of-the-art human-machine interface (HMI) of the AluMet 1800V and its fully automated process control consistently guarantee high throughput with perfect results. Highly efficient processing is further aided by the double-door design with a set of six pylons per door. Offering a coating area of up to 15 m² per batch the AluMet 1800V delivers tremendous productivity.
The powerful vacuum pumping system, the highly efficient thermal evaporators and high-rate plasma-enhanced chemical vapor deposition (PECVD) sources are the key to short cycle times. For example, the AluMet 1800V can deposit a highly reflective aluminum layer, plus protective top coat, onto a typical car-lamp reflector in approximately 20 min-.

Low production cost thanks to efficient consumable utilization
The AluMet 1800V highly efficiently uses production-cost-driving consumables such as evaporator filaments and aluminum evaporation material. Since the lifetime of the filaments is physically limited to a certain number of evaporation cycles, the AluMet 1800V’s high load capacity helps to drastically lower the consumables cost per coated piece. Furthermore, the optimized aluminum evaporator geometries allow for a maximum collection efficiency, which results in a high evaporation material utilization.

Robust design for high reliability
Employed in the automotive industry worldwide, the AluMet 1800V is more than able to demonstrate its unique reliability and robustness in a mass production context. This unbeaten reliability is the result of ongoing robust and smart machine design. All key components such as the evaporators and the PECVD stations are designed for 24/7 production and to ensure a high machine uptime, all serviceable components are easy to access and simple to maintain.

Versatile pylon system for more production flexibility
The planetary substrate holder system with its six pylons per door is capable of handling a wide range of substrate types and sizes. This makes Bühler Leybold Optics’ AluMet 1800V a very versatile and flexible system, suitable for many different production scenarios and environments. In addition, the ergonomic design of the pylon holder system allows fast and easy handling of the pylons during loading and unloading of substrates.

Compact design means minimum floor space requirements
The AluMet 1800V is mounted in a compact and easy-to-handle steel frame. As a result, the system has a space-saving footprint of approx. 45 m² in total. The machine’s steel frame makes its installation and if required, relocation, fast and straightforward.

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.

Product category: Sputtering targets for flat glass coating


The DynaJet is the newest member of the Dyna family of metallizing systems. This batch sputtering system combines the best of all PVD expertise that Bühler has to offer. The proven IPT cathode provides a new dimension in productivity. High target utilization offers lower cost of ownership due to a long target lifetime. The turbo molecular pump system needs only a fraction of the electrical energy and cooling water compared to conventional systems. All this allows for a significant reduction of the yearly cost of ownership.

Energy efficient metalizer for lower OPEX
Average energy consumption is an important aspect for the cost of ownership. The new pumping system of the DynaJet with TMP saves 800.000 kWh in 10 years compared to competing machines in the market. Together with faster ramp-up and ramp-down times for the high vacuum pumps and lower water consumption, DynaJet is setting a new benchmark, making it the best investment for the future.

Higher throughput and lower manpower costs
The automatic substrate load- and unload function allows a production line that can work automatically with higher throughput and lower manpower costs.
A dry air venting system allows for constant production independent environmental conditions. This feature permits faster pump down and a higher metallization quality resulting in a shorter cycle time.

Small footprint for optimized production space
With a required floor space of less than 10m², DynaJet is easy to integrate into your existing factory.
The machine is on a compact, container-sized frame for easy transport on site or to another production facility.

PECVD and PVD at the highest rate and best homogeneous distribution
The worldwide proven IPT cathode and an optimized cryo-coil guarantee the best PVD homogeneity. A semi-transparent sputter layer is another possible application. The optimized Bühler Arc management ensures a stable sputtering process.
New developments in the plasma-enhanced chemical vapor deposition (PECVD) process enable high speed top coating.
