Innovative Injection Molding Manufacturing: 2K, Overmolding & Rotating Mold Solutions

In today's competitive manufacturing landscape, advanced techniques like 2K injection molding, double shot molding, and overmolding are revolutionizing how complex plastic components are produced. At Derco, we specialize in precision injection molding manufacturing utilizing these cutting-edge processes to deliver superior results for automotive, medical, and electronic applications.


2k injection molding


Understanding 2K Injection Molding Technology

2K injection molding (also called double shot molding) enables the production of multi-material components in a single manufacturing cycle. This process utilizes:

  • A rotating mold system (rotate molds) that transfers the initial substrate to a second cavity

  • Precisely timed injection of two compatible yet distinct materials

  • Temperature-controlled zones to ensure proper material bonding

Our 2K injection molding capabilities allow us to create:
Soft-touch grips with rigid cores
Sealed assemblies with integrated gaskets
Color-contrast components without post-processing

The Overmolding Advantage

Overmolding takes injection molding manufacturing to the next level by:

  1. First injecting a substrate material (typically rigid)

  2. Then molding a secondary material (often flexible) over the base

  3. Creating permanent chemical or mechanical bonds between materials

Common overmolding applications we manufacture include:
Medical devices with ergonomic grips
Waterproof electronic enclosures
Vibration-dampening automotive components

Rotating Mold Systems for Complex Geometries

Our rotate molds technology provides several manufacturing benefits:

Increased Efficiency

  • 180° or 360° rotation capabilities

  • Simultaneous cooling and injection phases

  • Cycle time reductions up to 30%
