Double injection, or Double-Shot Moulding, is a sophisticated molding process used to integrate two different materials into a single piece. Widely valued in industries that demand resilience and adaptability, this method involves molding an initial plastic part and then injecting a second material around it.
At Solera, we leverage this technique to create products that combine strength and flexibility in one unit—a key factor for long-lasting electrical and industrial components.
What is Double Injection Molding?
Double injection molding is a two-stage process. In the first stage, a base component is formed, which then passes to a second mold where a secondary material is added.
This enables the final product to incorporate the properties of both materials—achieving enhanced durability and other desirable attributes, such as impact resistance and waterproofing.
Historical Roots: The Origins of Double Injection
This technology dates back to the 1970s, primarily used in mechanical keyboard manufacturing. Back then, it created keys with a durable core and a softer, visible surface.
With the shift to membrane keyboards, this method faded in the keyboard industry but later gained renewed interest across sectors that require intricate plastic designs.
Benefits of Double Injection in Modern Manufacturing
Double injection molding offers a number of important benefits:
- Structural Integrity: Combining materials without seams reduces risk of leakage and enhances durability.
- Cost and Time Efficiency: The process eliminates the need for post-assembly, streamlining production.
- Enhanced Safety: Automation allows for safer handling, as there’s no need to transport products between machines.
- Optimal Material Use: Products can have varying strengths in different areas, leading to efficient and resilient designs.
Applications in the Electrical and Industrial Sectors
Double injection is particularly useful in the electrical and industrial fields, where robust, weather-resistant components are required.
At Solera, we use this technology to make enclosures, covers, and other products that meet high safety standards and perform reliably even in challenging environments.
