Two-Shot Molding(Double Injection Molding): Colorful Solutions for Plastic Parts

Two-Shot Molds (also three and four-shot) are a cost-effective method to produce plastic parts with two or more colors molded at the same time, such as radio control buttons or dashboard faceplates.

Two-Shot molding is a relatively new, rapidly growing technology. It is replacing older, two-step systems, eliminating a secondary process to add logos, graphics or text. New computer technology and advanced materials have promoted the growth of the two-shot process.

The two-shot process first injects one color material into the mold, then injects the second color around or over the first. There are also multi-shot processes for parts with more than two colors (tail-lights can have up to four colors, for example).

The two shot process allows you to:

• Increase product features
• Enhances design aesthetics
• Reduce assembly steps and costs
• Improve quality
• Reduce cost per part

Two-Shot Molds: Benefit From New Technology

Some of the benefits of producing plastic parts using a multi-shot molding process include:

• Produce more complex parts
• Produce multi-colored or multi-resin parts
• Parts with movable segments or components using “in-mold assembly”
• Eliminate post-molding assemblies, such as:
  • Snap-fits
  • Ultrasonic welding
  • Adhesives
  • Screws or bolts
• Allows the first material to cool before the second one is injected

Applications for Two-Shot Molding

Designers and engineers are constantly coming up with new uses for plastic parts produced with the two, three or four step molding process. Just a few of the many types of these products include:

• Multi-color parts
• Toys with movable parts
• Flexible hinges
• Parts with seals molded in
• Soft grip handle inserts
• Automotive A/C or heater louvers
