    • Magnetized bezel or stiffener insert molding
    • Soft seal tooling and integrated glass fixturing systems
  • Lead mold design reviews; verify parting lines, gating, runner systems (hot & cold), steel selection, shrink rates, cooling strategy, and texturing requirements.
    • Ensure tool designs incorporate requirements for glass edge protection, dimensional stability, adhesion performance, and sealing surfaces.
    • Maintain complete data retention: 2D/3D tool designs, CMM reports, process sheets, hot runner data, and material/manifold documentation.
• Manufacturability & Product Integration
  • Evaluate new product quotes for feasibility of glass encapsulation molding, including:
    • Glass edge tolerances and flatness
    • Cross section design for seals, beads, and retention features
    • Adhesion and overmold bonding requirements
    • Gate location impact on flow induced stresses in glass and polymer
  • Collaborate with Designers, Program Managers, Tooling Suppliers, and Project Engineers to ensure product design supports robust encapsulation manufacturability.
    • Participate in product design reviews to confirm draft, shut offs, retention geometry, gaging datums, and warp/shrink predictions meet customer specifications.
• Tool Build Management & Launch
  • Prepare, manage, and approve tooling quotes for encapsulation tools within the corporate system.
  • Track tool builds through timing plans, supplier visits, milestone reviews, and PPAP readiness.
  • Lead sampling and launch of new tools including:
    • Glass loading validation
    • Overmold sealing performance
    • Adhesion / peel testing
    • Tool debug for short shots, flash, sinks, voids, and stress marks
  • Validate tooling and equipment through CMM layout, glass fixture verification, and encapsulation profile conformance.
  • Oversee texture (grain) approvals and surface quality reviews.
  • Define and release spare parts, preventive maintenance plans, and critical spare steel.
  • Support packaging, racking, and gage design reviews.
• Analysis, Testing & Supplier Interaction
  • Direct Mold Flow and CAE studies specific to encapsulated glass:
    • Flow front around glass substrate
    • Knit line and adhesion risk areas
    • Cooling of non uniform wall sections
    • Polymer stress transfer into glass edges
  • Maintain material line cards including TPE, PVC, PC/ABS, TPU, and specialty encapsulation compounds.
  • Support supplier tool builds, including on site assessments of mold design, machining quality, tryout equipment, and process capability.
  • Support component and system testing including:
    • Glass adhesion pull tests
    • Weathering & UV durability
    • Thermal cycling and expansion mismatch evaluation
  • Troubleshoot issues for existing programs (e.g., de lamination, glass cracking, warp, dimension failures).
  • Participate in formal supplier evaluations after project completion.
• Documentation & Reporting
  • Document all technical decisions, tool modifications, sampling results, and validation activities.
  • Maintain accurate, updated timing charts and project status for all assigned tools.
  • Prepare cost reports, variance analyses, and support budgeting and forecast activities.
• Process & Continuous Improvement
  • Maintain expertise in emerging encapsulation tool technologies, such as:
    • Advanced hot runner systems for hybrid materials
    • Tool steel performance for glass contact areas
    • Adhesion promoting surface treatments
  • Support implementation of new materials including TPE, low gloss PVC, PC/ABS, and future encapsulation compounds.
