Product category: Vacuum coating equipment
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 1800Vs 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 machines steel frame makes its installation and if required, relocation, fast and straightforward.
The Bühler Leybold Optics ARES machine platform has been conceived to meet the specific requirements of East Asian mass manufacturers for the cost-optimized mass production of components for the precision optics industry. Derived from our SYRUSpro series, the configuration is thoroughly streamlined according to the specific application, but never compromises on quality. Its ease of use in combination with production proven local components makes the ARES series a powerful tool for cost-effective 24/7 high volume production based on one hundred percent Bühler Leybold Optics technology. High reliability through proven design in combination with a fast return on investment.
A fast return on investment is achieved by ARES coaters since they provide a coating technology which perfectly matches market demands for a very reasonable capital outlay. The machine concepts themselves are based on the proven designs of our SYRUSpro series. In such ARES coaters are equipped with key components designed and made by Bühler Leybold Optics and use in parallel numerous locally sourced parts, adapted to specific customer requirements.
Various chamber sizes to meet the customers' demands.
ARES series machines are available in various chamber sizes, from ARES 700, ARES 1100 and ARES 1350 to the high volume production systems ARES 1500 and ARES 2000. A high variety of coating operations can be implemented into the production process in a cost-efficient manner. At the same time, ARES coaters deliver a very strong performance relative to requested coating specifications.
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 machines 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 machines 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 doors 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.
(80 … 720 pairs/8 h) Bühler Leybold Optics CHC series provides a comprehensive cleaning and hard coating solution for all ophthalmic needs within one single machine. Based on a thorough preparation of the substrates utilizing ultrasonic pre-cleaning, the CHC machines provide outstanding coating quality on lenses hand in hand with Bühler Leybold Optics process know-how.
