injection molding manufacturing engineer.

Responsibilities:
1. PEEK Injection Molding Process Engineering
- Develop, validate, and optimize injection molding processes for PEEK.
- Establish stable process windows including:
- Melt temperature control (360?400?C range)
- Mold temperature strategy (crystallinity control)
- Injection velocity profiling
- Pack/hold optimization
- Cooling and cycle time modeling
- Conduct DOE studies and drive Cp/Cpk improvement.
- Manage proper resin drying and contamination control protocols.
- Support mold trials and production launch readiness.

2. Tooling Design Guidance (DFM Leadership)
- Provide structured DFM feedback on:
- Wall thickness uniformity
- Gate location & sizing
- Venting for high-temp materials
- Shrink rate prediction
- Warpage mitigation
- Flow length-to-thickness ratio
- Review and approve mold designs before release.
- Advise on:
- Tool steel selection for high heat loads
- Mold temperature control systems
- Hot runner compatibility for PEEK
- Ejection design for high crystallinity parts
- Interpret mold flow simulations and validate assumptions.

3. Quoting & Technical Cost Modeling
- Evaluate new PEEK part opportunities for manufacturability and risk.
- Develop technical cost models including:
- Estimated cycle time
- Machine size requirements
- Material consumption & runner waste
- Expected scrap rate
- Secondary operations (machining, annealing, inspection, assembly)
- Tooling complexity and cavitation strategy
- Provide gate location and tooling concept recommendations during the quoting phase.
- Assess part geometry risks that affect cycle time or dimensional stability.
- Partner with Sales to ensure quotes are:
- Technically feasible
- Margin-protective
- Based on realistic process assumptions
- Identify when parts should be molded vs. machined from PEEK stock.
- Participate in customer technical reviews when needed.

4. Process Analysis & Continuous Improvement
Lead root cause analysis for molding defects:
- Voids
- Warp
- Incomplete fill
- Flash
- Crystallinity variation
- Reduce scrap and improve first-pass yield.
- Standardize best-known process parameters.
- Improve OEE through cycle time and downtime reduction.
