An innovative manufacturing process combining two different materials or colors in a single mold cycle.
Two-shot molding, also known as dual-shot or multi-component injection molding, is an advanced manufacturing technique that allows the production of complex plastic parts using two different materials or colors in a single molding cycle.
This sophisticated process involves injecting the first material to form the base component, followed by a rotation of the mold or transfer to a second cavity where the second material is injected. The second material bonds chemically or mechanically to the first, creating a single integrated component with different properties or aesthetics.
The advantages of two-shot molding are numerous. It eliminates the need for assembly of separate components, reduces labor costs, increases production efficiency, enhances part design flexibility, and improves overall product quality. This technology is particularly valuable for creating parts with complex geometries, multiple colors, or components requiring both rigid and flexible elements.
At GBM Mould, we have mastered the two-shot molding process to deliver high-quality, cost-effective solutions for diverse industries including automotive, consumer electronics, medical devices, and household appliances.
Explore the different variations of 2 shot molding technology and their unique applications
The conventional method where two materials are injected sequentially into different cavities of the same mold.
Key Benefits:
Common Applications:
Ideal for parts requiring different colors or materials like tool handles, remote controls, and automotive components.
A variation where a second material is molded over an existing first-shot component, often to provide grip, comfort, or sealing.
Key Benefits:
Common Applications:
Commonly used for toothbrushes, razors, tools with soft grips, and electronic device casings.
A process where a pre-formed component is placed in the mold cavity before injecting the second material around it.
Key Benefits:
Common Applications:
Frequently used for electrical connectors, metal-reinforced components, and medical devices.
A specialized technique where the mold core retracts after the first shot to create space for the second material.
Key Benefits:
Common Applications:
Used for automotive interior components, complex housings, and parts with thick/thin sections.
