Dyeing | Surface Finishes for Metal and Plastic Parts

Dyeing

Description

Dyeing is done in a special solution containing dyes and particular chemical material. Dye molecules are fixed to the fiber by absorption, diffusion, or bonding with temperature and time being key controlling factors. Usually the result of dyeing will have a certain color difference.

Design considerations for Dyeing

While dyeing can be used to create unique patterns and designs, it may not be as versatile as other surface finishing processes such as printing or coating.
Depending on the type of dye used and the material being dyed, the color may not remain stable over time.
Dyeing can be a more expensive surface finishing process than other methods such as printing or coating, particularly for small quantities.

The Justway Dyeing process

Dyeing is often more environmentally friendly than other surface finishing processes, as it typically uses less water and energy than other methods such as printing or coating. Let’s break down the basic steps for dyeing a part:

Prepare the material for the dyeing process
The next step is to select the appropriate dye for the material and the desired color
The material is then immersed in the dye solution, either in a dye bath or through a process of spraying or brushing the dye onto the material
Wash to remove excess dye and fix color
