Engineering Work Experience

Princeton Technology Corporation - Hudson, NH. June/2017 – June/2018

Process Engineer Intern

• Designed complex molds for printed circuit board overmolding using SolidWorks

• Analyzed flow of materials using SolidWorks Plastics

• Optimized processes for printed circuit board overmolding by trialing variable parameters; injection pressure, injection speed, hold time, packing time, hold pressure, packing pressure, molding time, and de-molding time

Freudenberg Medical - Gloucester, MA. May/2016 - August/2016

Project Engineer Intern

• Managed a silicone vertical press injection molding machine

• Worked in a team to optimize and validate several different processes to produce fully functional, cosmetically pleasing gastro-intestinal tubes

• Optimized processes by trialing variable parameters; injection pressure, injection speed, hold time, packing time, hold pressure, packing pressure, mold temperatures, molding time, and de-molding time

• Created de-molding fixture to extract core pins from molded parts using collets and air pressure

• Disassembled, cleaned, and reassembled three plate cold-runner molds to ensure consistency between runs

Lubrizol Advanced Materials - Wilmington, MA. May/2015 - August/2015

Chemical Synthesis Intern

• Filled wet and dry chemical ingredient resin orders based on the customers’ characteristic needs. Weight and volume scales were used extensively to produce the work product

• Responsible for complete and accurate reporting of quality control data

Summary of Technical and Laboratory Skills

Processing: Thermoplastic injection molding, silicone injection molding, extrusion, extrusion blow molding, fiber extrusion, thermoforming, and rotational mold engineering

Testing: Drop-dart, izod, charpy, and tensile testing

Software: SolidWorks, SolidWorks Plastics, Mold Flow, MATLAB, and Microsoft Office (Word, Excel, PowerPoint)

Academic Project Related Experience

• Fiber Extrusion Capstone Project: Understand a fiber extruder, research and understand the abilities of the extruder, optimize a fiber extrusion process, and determine a process in order to produce an extrudate matching the properties of black widow spider silk

• Mold Flow: Design and create a 2-plate, single cavity mold, which was used to injection mold golf tees, ball markers, and divot tools

• Introduction to Design: Create and 3-D print a miniature SolidWorks model of headphones
