Forensic Metal Vacuum Deposition System Fingerprint Remark Imaging Portable Design

Forensic Vacuum Metal Deposition System is customized designed and made exclusive for police equipment. Royal Technology spend  9 months to coordinate with customer, after over 20 technical meetings discussion and modification,  the 1st machine was finally born in the year of 2018.

The advanage and benefits:

1. Portable design with compact footprint

2. Water-cooling free system, the required working environment is only electric power: 1Ph, 220V 50Hz, 60A;

3. Large view port to inspect the evaporation process, with Quartz window up to 400mm;

4. Powerful vacuum pumping system for fast cycle coating process: high turbo molecular pump, available for assemble at any direction; equipped with one large volume of 2-stage rotary vane pump.

5. Low running cost and low maintenance cost.

6. Flexible operation based on HMI device: processing page, curve record page, alarm page, maintenance pages etc. The data logging in and USB connection port for downloading the processing data.

Work pieces materials can be: plastic, metals, steel, polymer, paper, fabric or glass materials, bank card, gun etc. crime pieces.
