Injection Molding Manufacturing Engineer

Job details We are seeking a hands-on Manufacturing Engineer with PEEK injection molding experience who can both:
- Develop and optimize high-performance polymer molding processes
- Provide technical input and cost modeling for quoting new PEEK programs

This role bridges Engineering, Tooling, Production, and Sales. The right candidate understands processing, tooling design, and the financial drivers behind successful quoting. ...
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.

Working hours: 8:00 AM - 5:00 PM

Skills:
- Programming experience preferred.
- Solidworks experience preferred.

Education:
Bachelors

Experience:
4-7 years

Qualifications:
- Bachelor's (Required) - in any Engineering or Engineering Technology
- 5+ years injection molding experience.
- Proficient in CAD (Solidworks preferred)
- Mechanically / electrically inclined
- Direct production experience processing PEEK.
- Demonstrated experience quoting molded components or building cost models.

Strong understanding of:
- High-temperature barrel systems
- Mold thermal control
- Scientific molding principles
- Tight tolerance molding
- Ability to interpret mold flow results and apply them to cost assumptions.

Mathematics: The candidate must know how to use a scientific calculator, understand addition, subtraction, multiplication, trigonometry, and some basic algebra.
Physical: You must be able to lift 45lbs to chest level. You must be prepared to stand during work hours.
