Quality By Design.
For over half a century, Craftsman Tool & Mold has redefined excellence in mold base manufacturing, specializing in high-precision Stack Mold Bases and Rotational Spin Stack Mold Bases for the multi-shot injection molding industry throughout North and South America. Craftsman's investment in routine laser calibration and metrology systems guarantees dimensional accuracy and production consistency across every program. It’s how we achieve the kind of results our customers count on, time and time again.
Operating within our climate-controlled, 40,000-square-foot facility—equipped with 30,000 lb lifting capacity and machining dimensions up to 87 inches wide by 167 inches long; we deliver mold base solutions designed for performance, scale, and reliability. Whether targeting advanced In-Mold Labeling (IML) or In-Mold Assembly (IMA) applications, our mold bases are engineered with Quality by Design principles and manufactured with unmatched attention to detail. Cavitation demands regularly exceed 144 cavities, with tolerances often held to microns, ensuring flawless alignment and repeatability.
When precision isn’t optional, and performance must be proven, Craftsman Tool & Mold Company delivers.
Mold Base TypesStack Bases: Core design for multi-tier mold systems; enable increased output and reduce cycle time. Rotational Spin Stack Bases: Advanced stack mold configurations with rotating capabilities; ideal for multi-shot molding with sequential material injection. Multi Cavity Bases: Accommodate numerous identical cavities for high-volume production; often require ultra-precise alignment and cooling. Multi Shot Bases: Allow molding of parts using multiple materials or colors in a single cycle; demanding in terms of alignment and material flow. |
Manufacturing Processes & Capabilities
These are the supporting systems that enable precision and consistency:
- Gun Drilling: Critical for creating deep, straight cooling channels or ejector pin holes in thick steel plates.
- CNC (Computer Numerical Control): Core machining method used to produce complex, high-tolerance geometries with repeatability.
- Grinding: Essential finishing operation to refine surface flatness and parallelism; improves sealing and alignment between mold components.
Engineering and Data Input
- CAD Data: The blueprint for simulation, machining, and inspection.
- FTP Site Instructions: These are part of the digital infrastructure that support collaborative workflows. They enable easy and secure sharing of CAM files, CAD data, toolpath updates, and inspection reports between engineering, toolroom, and customer teams.
- CAM Systems: Lemoine, Delcam PowerMILL, Vericut These Computer-Aided Manufacturing tools transform CAD models into executable toolpaths.
- Lemoine: Handles complex machine instructions. Renowned for post-processing and managing complex multi-axis machine instructions.
- Delcam PowerMILL: High-speed toolpath strategies. Offers high-speed toolpath strategies, particularly valuable for high-precision mold components.
- Vericut: Simulates CNC programs to avoid crashes. Used to simulate and verify CNC programs before real-world machining to avoid crashes and ensure accuracy.
