Two color 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 color mold 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 color process is first to inject one color material into the mold and cooling down,after the open and core side rotating180 degree, then injects the second color around or over the first. There are also multi-shot processes for parts with more than two colors ,The two shot process allows you to:

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

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

• Produce more complex parts;
• Produce multi-colored or multi-resin parts
• Parts with movable segments or components using on-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

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 into plastic
• Soft grip handle inserts
• Automotive A/C or heater louvers
