Advantages of Two-Shot Molding

Medical device manufacturers count on their supply chain partners for answers. What processes can be adjusted to add value and reduce cost? What methods can be used to streamline manufacturing processes, reduce SKUs, and improve part quality? One way is by moving from single component molding to two-component molding.

Two-component injection molding (also known as two-shot, 2C or 2K) adds value for the device maker as they will not have to build and validate two different molds. This process reduces assembly or eliminates it altogether and reduces the amount of part numbers - further simplifying the overall manufacturing process.

Advantages include:

• Lower costs with fewer steps, fewer parts, less assembly, less handling and manual labor
• Higher quality due to fewer defects, as manual labor leads to defects and potential contamination
• Reduction in waste
• Strong bonds between mating parts & materials, specific benefit when leak-proof parts and systems are of concern
• Improved quality, aesthetics, and functionality by combining different materials with different physical properties
• Reduction in cycle time provides faster manufacturing and throughput
• Combining multiple part performance into one component
