30ml slant glass dropper bottle new product

The manufacturing process depicted involves the production of a two-part item consisting of an aluminum component and galss bottle body.

The aluminum component, likely constituting some type of closure, lid or base for the bottle, undergoes an anodizing process to impart a black finish. Anodizing involves placing the aluminum piece in an electrolytic bath and passing an electric current through it, causing a thin oxide layer to form on the surface. This oxide layer, along with dyes added to the electrolyte, give the metal a colored finish. In this case, the black dye results in an attractive matte black anodized finish.

The glass bottle body then undergoes two finishing processes. First, a semi-transparent gradient coating is applied, likely through a spray coating technique. This results in a gradual color transition from black near the bottom to yellow near the top of the bottle. The effect is aesthetically pleasing and gives the impression of depth, shadow and light.

Finally, a single color white silkscreen print is applied to the bottle body. Silkscreen printing involves the use of a stencil to block out areas where ink is not wanted, allowing ink to be applied to just the desired areas through the open parts of the stencil. This white print likely contains branding information, product details or other graphics to identify and customize the bottle.

In summary, the combination of anodized aluminum and gradient coated, printed plastic demonstrates an effective use of complementary finishes and materials to create an attractive and functional consumer product.
