About this role

The Mississippi Polymer Institute is seeking a hands-on, detail-oriented Polymer Engineering Intern for a 10-12 week summer program. In this role, you will bridge the gap between material science and mechanical design by developing 3D CAD models, 3D printing and assisting with polymer extrusion and injection molding processes.

This comprehensive, customizable summer internship blends CAD modeling with polymer processing. It is tailored to attract engineering students who can help design plastic components, optimize tooling, and support and conduct production runs.

You will work within the Mississippi Polymer Science Institute at The University of Southern Mississippi in Hattiesburg. The environment combines hands-on production and laboratory work with collaborative engineering problem-solving.

This internship offers the opportunity to apply academic knowledge to real-world polymer processing challenges. You will gain practical experience in process troubleshooting, material testing, and documentation that supports continuous improvement.

Requirements

Currently pursuing a bachelor’s degree in Polymer Engineering, Materials Science, Plastics Engineering, or a related field.
Foundational proficiency in CAD software (SolidWorks, AutoCAD, or Fusion 360).
Basic understanding of polymers, plastics processing, or manufacturing principles.
Strong problem-solving skills with a willingness to work in a hands-on production and laboratory environment.
Excellent written and verbal communication skills.
Proficient in Microsoft and Apple computer programs.
Experience in 3D printing.
Experience in polymer extrusion and injection molding.

Responsibilities

Assist the engineering team with monitoring, setting up, and optimizing polymer extrusion and injection molding runs.
Help collect and analyze production data (e.g., cycle times, yield, scrap rates) to troubleshoot part defects and improve process stability.
Create and modify 3D CAD models and 2D engineering drawings of plastic components, tooling, and fixtures using software like SolidWorks or Autodesk Inventor.
Print CAD files on 3D printers for clients.
Prepare, compound, and test polymer samples to evaluate material performance and mechanical properties.
Update process guides, standard operating procedures (SOPs), and bill of materials (BOMs) as production changes occur.

Benefits

Hands-on experience in a university-based polymer research and production environment.
Opportunity to work with state-of-the-art polymer processing and 3D printing equipment.
Customizable internship experience tailored to your interests within polymer engineering.
Exposure to real-world process troubleshooting and material testing.
