Material pairing
The two resins must be reviewed for melt temperature, chemical compatibility, shrinkage, bond performance and the product environment.
PLASTIC INJECTION MOLDING
Two-Shot and Double-Color Injection Molding
Two-shot molding produces an integrated component through two controlled injection stages. Createch supports double-color tooling and molding programs where material pairing, interface geometry, cosmetic alignment and repeatable bonding are central to the design.
Capability overview
Built around the part, tool and production requirement
Two-shot molding produces an integrated component through two controlled injection stages. Createch supports double-color tooling and molding programs where material pairing, interface geometry, cosmetic alignment and repeatable bonding are central to the design.
Createch connects product review, injection mold manufacturing, process development, controlled molding and applicable secondary operations through operations in China and Mexico.

Common applications
Plastic parts and programs to evaluate
Final manufacturability depends on geometry, resin, tolerance, finish, annual volume and validation requirements.
Dual-color cosmetic componentsIntegrated grips and touch surfacesButtons and control interfacesRigid-and-soft material combinationsParts designed to reduce separate assembly
Engineering and sourcing
What matters before production begins
Interface design
Mechanical locks, shutoffs, flow direction and material overlap determine how the two shots meet and remain integrated.
Tool architecture
Rotary, transfer or other two-stage tool concepts depend on part geometry, press configuration, annual volume and appearance requirements.
Validation
Bond strength, dimensions, color, flash, interface appearance and functional performance require defined acceptance criteria.
Manufacturing footprint
Injection molding in China and Mexico
More than 90 injection molding machines cover an approximate combined range of 40T to 600T.
The Dongguan operation supports product development, injection mold design and build, molding, finishing and complete assembly. The Tultitlán operation supports North American production with 34 presses from 40T to 550T, insert molding, assembly, quality and on-site mold maintenance.
