Remarks: The size of the vacuum chamber can be customized according to customer's product and special process requirements

Equipment characteristics
Production period: -900sec (15 minutes)/1 period shorter than that of similar equipment
Coating method: heating wire evaporation coating method
Coating quality: Each door has 6`8 sets of fixtures, and the coating thickness is uniform at the same time for autobiography and revolution. It is suitable for mass production of economical car lamps. Dehumidification capacity: The vacuum chamber is equipped with an ultra-low temperature freezing system below minus 140 degrees to fully absorb moisture. Vacuum reach speed
Operating cost: The volume of the vacuum chamber is relatively large, the number of coatings is large each time, and the operating cost of a single piece is low
Number of fixtures: According to the size of the product, the fixture can be changed to 6 axis or 8 axis at will, without any installation and adjustment when changing
Floor area: double-door structure, relatively smaller installation area and operation area than similar equipment
Operation method: The man-machine interface can be set and monitored intuitively, and the person who has no management password can not change it
After-sales service: There is an after-sales service center and parts warehouse, which can quickly deal with problems in use

Equipment principle diagram

 

Left: Apply a certain voltage to the heating wire in a suitable vacuum environment to evaporate the aluminum wire placed on the heating wire to the surface of the rotating product to achieve the purpose of aluminum plating.

Right: According to the size of the product, change the 6-axis fixture at will, (when the product size is relatively large, each vacuum chamber is equipped with six fixtures) or 8-axis (when the product size is relatively small, each vacuum chamber is equipped with 8 fixtures), it is not necessary for replacement Any installation and adjustment.
