Sr Engineer, Plastics

The Plastics/Injection Molding Engineer is responsible for driving mold process development and injection molding projects through adherence to established product design, scientific injection molding process, tooling, resin, and equipment. The key responsibility of this position is to lead molding qualification activities and continuous improvement with established manufacturing. Responsible for leading projects and actions that result in improved quality, process stability, and reduced cost.

Duties and Responsibilities

• Experienced in setting up robust injection molding processes on multi-cavity molds and insert molding


• Experienced in process development utilizing Scientific Molding and Design Of Experiments (DOE) principles


• Subject matter expert in the ability to coordinate qualification activities (PPAP, IQ, OQ, PQ, DOE, etc.) to meet requirements of the application.


• Highly proficient in generating qualification requirements and reports for injection molded components


• Use and understanding of in-cavity sensors for process development


• Plan and execute new tool samples and/or attend tool samples performed at outside sources


• Prepare or update procedures, work instructions and process sheets as required


• Subject matter expert during product design reviews for manufacturing feasibility


• Understanding of Mold Flow analysis


• Knowledge of both Crystalline & Amorphous plastics resin (examples include polycarbonate, acrylic, PVC, Nylon and Co-polyesters)


• Use of Society of Plastics Industry Standards (SPI) for mold build classification and texture/surface appearance recognition


• Use and understanding of Statistical Tools (Design of Experiments, Measurement System Analysis/Gage R&R, Process Capability and Statistical Process Control)


• Develop and maintain strong working relationship with functional groups (Engineering, Quality Operations, Manufacturing)


• Proactively perform process improvement activities on existing processes to improve efficiencies, increase production output, reduce scrap, waste, handling damage, and non-conformances.


• Continuous improvement activities focused on cost reduction and communication of cost reduction project status.


• Responsibilities for some or all of the following: project management, process development, process print development, development of work instructions, and operator training on manufacturing processes.


• Become Subject Matter Expert for assigned processes and support customer, ISO, FDA, and internal audits.


• Comply with department procedures and ISO and FDA regulations.


• Development and implementation of process improvement projects as well as new process development, including working with outside contractors.
