DC Magnetron Sputtering Vacuum Metallization Machine For Disposable Tablewares

Disposable tableware vacuum metallization machine is a kind of equipment used to deposit metal film on the surface of disposable tableware (such as plastic knives and forks, bowls and dishes, etc.). It realizes the metallization treatment of tableware through physical vapor deposition (PVD) technology to improve its appearance, durability and functionality.

Vacuum metallization technology 
 In this technology, metal materials (such as aluminum and stainless steel) are heated in vacuum environment to gasify and deposit on the surface of tableware to form a uniform metal film. Common methods include:
 Magnetron sputtering coating: use high-energy ions to bombard the metal target, sputter metal atoms and deposit them on the surface of tableware. It is suitable for tableware with complex shapes. The coating raw material is stainless steel. 

 Evaporation coating: by heating the metal to the evaporation point, it is directly deposited on the surface of tableware, with high efficiency but slightly low film compactness, and the raw material generally used for evaporation coating is aluminum, not food-grade film.

Optional models:
Single-chamber equipment: simple structure, suitable for small batch production, small footprint. 
Double-chamber or multi-chamber equipment: strong continuous production capacity, suitable for large-scale industrial application. 
Magnetron sputtering coating machine: the film is compact and has strong adhesion, but the equipment cost is high. 
Evaporation coating machine: The cost is lower, but the film uniformity is slightly inferior to magnetron sputtering.

Main technical parameters: 
 Coating cycle: 10-15 minutes/batch (magnetron sputtering). 
 Power supply type: medium frequency (MF) power supply or DC power supply. 
 Control system: PLC automatic control,  manual/automatic switching are available.
 Equipment material: carbon steel or stainless steel, strong corrosion resistance. 
 Process gas: mainly argon, used to maintain the vacuum environment.
