Two materials. One component.
Plan two-shot injection tooling around the function of each material or color, the interface between them and the intended molding equipment. GPTMOLD reviews 2K mold enquiries for combined rigid, flexible, transparent and colored regions.
The first-shot part, transfer method and second-shot cavity need to work as one tooling system. Share the complete assembly requirements so the mold concept can be reviewed before construction.
Discuss a Two-Shot MoldSpecify both resin grades, colors and the function of each region. Review supplier guidance, shrinkage assumptions and whether the interface relies on adhesion, mechanical retention or both. Define the bond or retention test required for approval.
Identify the intended two-component machine and its interfaces. Discuss rotary, index-plate or core-back concepts against the actual geometry, transfer arrangement, shot sequence and part-removal needs.
Mark visible boundaries, critical dimensions and acceptable gate or parting-line locations. Agree how samples will be checked for color separation, bourrelets, assembly fit and interface performance.
Compatibilité des matériaux, registration, cycle time and final-part performance are project-specific items to confirm through engineering review and agreed trials.
Review the existing multi-shot tooling scope and component examples.
Explore substrate handling, locating features and overmold interfaces.
Connect multi-color and transparent regions with appearance and optical requirements.
