A two-color injection molding machine can form two defined regions in an integrated sequence. Its value depends on the part, mold, materials and handling requirements. Use the complete production cell to compare it with a separately molded substrate and a second molding operation.
Benefits to Evaluate
- Handling. An integrated transfer may reduce the number of times a substrate is picked up, stored or loaded.
- Location. A tool that locates and supports the first shot can help control the second-shot boundary.
- Assembly. Molding a grip or color region in place may replace a separate operation if the resulting part meets the application requirements.
Check the Tradeoffs
Compare the clamp and injection arrangement, mold complexity, access, tooling costs and auxiliary equipment. Two-color machines can use different orientations and transfer layouts. Check space using the complete cell drawing, including handling, service clearance and protective equipment.
Compare Accepted Output
Time both routes from loading through inspection. Record the number of acceptable parts, rejects, changeovers and labor requirements under comparable conditions. Include material loss, service and tooling in the cost comparison.
See the integrated and transfer process comparison and the machine purchasing checklist.
