Job description

The Mold Designer is responsible for the design and development of injection molds for plastic components, from concept through final production-ready tooling. This role requires hands‑on proficiency with Cimatron for mold design, core/cavity development, and CNC toolpath generation, along with a strong understanding of moldmaking principles, plastic part design, and manufacturing processes.

Key Responsibilities

• Design injection molds (single and multi‑cavity, family molds, hot runner and cold runner systems) using Cimatron
• Perform core/cavity splits, parting line development, and DFM (Design for Manufacturability) reviews on customer part models
• Generate detailed mold component drawings, BOMs, and assembly documentation
• Develop CNC toolpaths within Cimatron for mold base and insert machining
• Collaborate with tooling engineers, moldmakers, and process engineers to resolve design and fit issues during build and tryout
• Incorporate ejection systems, cooling layouts, gating, and venting into mold designs
• Review and interpret customer-supplied CAD data (SolidWorks, Creo, CATIA, NX) and translate into moldable geometry
• Support mold sampling, first-article inspection, and design revisions based on tryout results
• Maintain design standards, mold base libraries, and component databases within Cimatron
• Estimate design and build timelines for quoting purposes

Required Qualifications

• 3+ years of mold design experience in an injection molding or moldmaking environment
• Proficiency in Cimatron (mold design and/or CAM modules) required
• Strong understanding of plastic materials, shrinkage, and part design principles
• Experience with core/cavity design, hot runner systems, and standard mold components (DME, Progressive, Hasco, etc.)
• Ability to read and interpret 2D drawings and 3D models
• Familiarity with GD&T

Preferred Qualifications

• Associate's degree or technical certification in Tool & Die, Mold Design, or Mechanical Design
• Experience with additional CAD/CAM platforms (Moldflow, SolidWorks, NX)
