Injection Molding Engineer

Serigraph • West Bend, WI

About The Position

At Serigraph, injection molding isn’t the end of the process – it is the integration point. Our decorated plastic film is printed, formed, and precision trimmed before it ever reaches the mold tool. With gate design, resin selection, and a solid processing window, your job is to bring the whole system together, resulting in a complete class-A surface product.
If you haven’t done film insert molding before, that’s okay. If you’ve done technically demanding cosmetic molding – thin walls, optical surfaces, class A automotive trim – you already think the right way, and we want to hear from you.
In this role, you’ll own the injection molding side of new product launches from early DFM conversations with customer engineers through tool design, process development, validation and SOP. You’re the technical bridge from concept to launch. You'll work directly with the upstream printing and forming teams, because what happens before the film hits the cavity determines what you're working with.
The parts you launch end up in automotive interiors, appliance control panels, and backlit interface assemblies for global programs. The customers are sophisticated. The cosmetic standards are stringent. The work is real.
You’re the right fit if:
You've done technically challenging molding where visual quality matters as much as dimensions.
You build process windows that defend themselves - not just a stable run during validation.
You've worked cross-functionally on launches where you had to influence tool design, not just accept it.
You can talk through tradeoffs with a customer engineer and earn their confidence.

Requirements

• Engineering degree or equivalent hands-on experience
• 3+ years in injection molding process development
• Tooling design (CAD

Responsibilities

• Partner with customers and internal teams early to translate appearance/performance requirements into moldable, manufacturable designs (DFM/DFMEA mindset).
• Specify tool design and resin selection to enable a capable process.
• Own the molding technical deliverables within Serigraph APQP: build plans, DOE’s, process analysis, capability studies, process documentation, and launch readiness reviews.
• Partner with Operations for process development using scientific molding principles to establish a robust window and define critical-to-quality parameters.
• Create and update PFMEA’s, control plans, and measurement studies (Gauge R&R) to ensure process controls are effective and audit-ready.
• Troubleshoot molding issues during builds and launches; identify root cause and implement corrective actions.
• Drive improvements identified during builds and validation—cycle time, scrap reduction, cosmetic yield, and process stability.
• Evaluate and qualify tool partners for technical capability, launch discipline, and decorative molding experience.
