Injection Molding Process

Multi-Component (Multi-Shot) Molding (3K Molding)

Description

3K molding (Three-Shot Molding) is an advanced multi-material injection molding process that allows three different materials or colors to be combined into a single molded part in a single production cycle. Using specialized multi-component injection molding machines, this process enhances product functionality, aesthetics, and performance by integrating different materials with varying properties, such as rigid and soft plastics or multiple colors.


3K molding is best used for applications like multi-color buttons, ergonomic grips, and complex seals, reducing assembly costs while improving durability and design flexibility.

Benefits

3K molding allows for parts that are:

  • Higher volumes – Over 10,000 parts
  • Mid level to full production programs
  • Parts with up to 3 different colors in one part
