What are some common challenges faced by plastic process engineers in optimizing manufacturing processes?

Plastic Process Engineers often encounter challenges such as maintaining consistent product quality while scaling up production, troubleshooting equipment malfunctions, and minimizing material waste. They must continuously monitor and adjust processing parameters like temperature, pressure, and cycle time to ensure efficiency and compliance with specifications. Collaboration with design, quality, and maintenance teams is crucial to quickly resolve issues and implement process improvements. Staying updated with new materials and technologies also plays a key role in overcoming these challenges and advancing in the field.

What does a plastic process engineer do?

A Plastic Process Engineer is responsible for designing, developing, and optimizing processes involved in the manufacturing of plastic products. They work with various types of plastic materials and molding technologies, such as injection molding, extrusion, and blow molding. Their duties often include troubleshooting production issues, improving process efficiency, ensuring product quality, and collaborating with design and production teams to implement best practices. They also play a key role in selecting materials, setting process parameters, and maintaining compliance with safety and environmental regulations.

What is the difference between Plastic Process Engineer vs Plastic Technician?

AspectPlastic Process EngineerPlastic Technician
CredentialsBachelor's degree in plastics engineering, chemical engineering, or related fieldTechnical diploma or associate degree in plastics technology or related field
Work EnvironmentDesign, optimize, and oversee manufacturing processes in production facilitiesOperate and maintain plastic processing equipment on the production floor
ResponsibilitiesProcess development, troubleshooting, and process improvementMachine setup, operation, and quality checks

The Plastic Process Engineer focuses on designing and improving plastic manufacturing processes, requiring a higher level of education and analytical skills. In contrast, the Plastic Technician handles day-to-day machine operation and maintenance. Both roles are essential in the plastics industry, but they differ in scope and responsibilities.

What are the key skills and qualifications needed to thrive as a plastic process engineer, and why are they important?

To thrive as a Plastic Process Engineer, you need a solid background in chemical or mechanical engineering, polymer science, and process optimization, often backed by a relevant degree. Familiarity with CAD software, injection molding machines, statistical process control (SPC), and certifications like Six Sigma are commonly required. Strong problem-solving abilities, attention to detail, and effective communication skills help you collaborate with cross-functional teams and drive continuous improvement. These competencies ensure efficient production, high product quality, and innovation in plastic manufacturing environments.

Job description

Are you a hands-on manufacturing engineer who enjoys solving problems on the production floor, driving process improvements, and helping teams achieve consistent results?

We're seeking a Process Engineer to join our Conyers, GA manufacturing facility. This role plays a critical part in improving process control, standardizing manufacturing practices, and supporting continuous improvement initiatives across our plastics manufacturing operation. The ideal candidate is a self-starter who thrives in a fast-paced environment and is comfortable spending the majority of their time on the production floor rather than behind a desk. 

What You'll Do
  • Review, develop, and improve manufacturing process control plans.
  • Analyze production processes and identify opportunities for improved quality, efficiency, and consistency.
  • Troubleshoot manufacturing and processing issues and implement sustainable solutions.
  • Lead process investigations and root cause analyses.
  • Develop and maintain process documentation, standards, and operating procedures.
  • Partner with Production, Maintenance, Engineering, and Operations teams to improve plant performance.
  • Support process validation, testing, data collection, and continuous improvement initiatives.
  • Drive standardization and process discipline across manufacturing operations. 
What We're Looking For
  • Bachelor's degree in Engineering or related field preferred.
  • Equivalent manufacturing engineering experience will be considered, particularly within plastics processing.
  • 5+ years of experience in plastics processing, manufacturing engineering, or process engineering preferred. 
  • Experience in thermoforming, extrusion, injection molding, or related plastics manufacturing processes.
  • Strong knowledge of process controls, root cause analysis, continuous improvement, SPC, FMEA, DOE, and related methodologies. 
  • Demonstrated ability to independently manage projects, prioritize competing demands, and deliver results.
  • Excellent communication and cross-functional collaboration skills. 
Why This Role Is Different

This is not a traditional desk-based engineering role. Expect to spend approximately 80% of your time on the manufacturing floor, observing processes, gathering data, working directly with operators, and implementing improvements. 

Success in the First 90 Days
  • Review and assess existing process control plans.
  • Identify critical process gaps and opportunities for standardization.
  • Develop and implement updated control plans and process documentation for thermoforming operations.
  • Build strong partnerships across Operations, Maintenance, and Engineering teams.
