Injection Molding

The Polymers Center has three injection molding machines that are dedicated to training, research and development. Our molding machines support ongoing R&D that provides practical solutions to molding related problems. Additionally, we can provide support for mold trials, short-run product needs, extensive tooling trials and validations.

Our lab offers two 55-ton presses and one 110-ton press. We feature one all-electric, one hybrid-electric, and one hydraulic machine capable of running various plastics, ranging from commodity to engineering grades requiring higher mold temperatures.

Our injection mold inventory includes a spiral flow mold, a 2”x3” variable thickness plaque mold and an ASTM family mold for various testing – either in our testing lab or yours.

Wittmann Injection Molding Industry 4.0 Upgrade

A recent upgrade to our Wittmann Injection Molding machine allows all information to be viewed across all parts of the machine – the blender, dryer, and temperature control unit. No longer is it necessary to enter data to each component separately; now all parts automatically coordinate. In addition, the same information is presented on a computer or large video screen for training purposes.

Our Newest Addition

Regloplas P160S Temperature Control Unit

Regloplas Temperature Control Unit
The Regloplas P160S pressurized water temperature control unit is used for applications when optimum heat transfer is needed. The P160S is capable of controlling temperatures up to 160°C (320°F), with a pumping capacity of 40 l/min.

Plastic Parts Molds


Depending on the needs of our customers, molds can either be provided by the customer or the Polymers Center. The Polymers Center has molds that can be used if the goal is to test the material. Customers can choose from our ASTM family mold which includes an Tensile Bar, IZOD Impact Bar, and a Gardner Impact disk, or our variable thickness 2”x3” plaque mold. Customers also have the option of bringing a mold of their own to verify that it will produce good parts. Please contact Amanda Hurd at (704) 602-4105 for allowable mold dimensions.

Customer Testimonials

“I have found The Polymers Center of Excellence to be an excellent laboratory for all the polymer testing we do on our products. They are both responsive and efficient with the work they do for us. Carl Thomas does an excellent job in getting the information to us quickly and thoroughly in his reports. He is always a phone call away should we need him to interpret the data for us. PCE also has worked closely with us in developing specialty compounds for the polymer marketplace. There variety of twin screw compounding lines allows us not only to prototype our compounds in small quantities, but once we have established a working formula, their larger lines suit us perfectly for production size runs. The staff at PCE are courteous and efficient. I would recommend them to anyone for their polymer testing, operator training, or specialty compounding needs.”

Ray Dlugos, President, Ace Plastics Inc.

“PCE has been a benchmark – gold standard partner for Microban International. We have expanded the breadth and depth of our product range four-fold over the last several years and they have been there with us every step of the way. Their expertise, unique problem solving ability, high standard of quality and safety and hyper focus on customer satisfaction are a model for us all.”

Thomas Kotterer, Vice President Global Operations, Microban International Ltd.

“I attended four courses put on by the Polymers Center of Excellence, and quite frankly they are the most practical and useful training classes I have had so far in my career. The instructor, Joe Henz, literally brought boxes full of examples showing well designed parts as well as failures and the causes for them, manufacturing defects, gating and much more. The course handouts contained many pictures and clear explanations, and even today they are some of the most heavily used resources on my bookshelf. If you are looking for a solid introduction to plastics, I highly recommend the Polymers Center of Excellence for your training needs.”

Jeff Wickham, Founder, Medical Device Engineers Network

“For those looking for testing, evaluation of existing plastic products, prototyping and developing new products, the Polymer s Center for Excellence is your go-to source. Their test and production equipment is up to date and functional. The personnel who oversee the equipment are professional and knowledgeable, many having come from the Plastics Industry with impressive academic backgrounds. In a sentence, they know what they are doing! They can and will answer your questions honestly. In the event they do not know the answer or you require additional information they will not hesitate to let you know they find out. It was refreshing to discover such a remarkable polymer resource right here in North Carolina. No need to go to Texas or New Jersey anymore. I applaud PCE’s efforts and accomplishments in putting together such a remarkable facility.”

Thomas A. Hempstead, Quality Packaging Company of NC

“Earth Renewable Technologies focuses on making environmentally friendly packaging products. One of the reasons I enjoy working with the Polymers Center is that they are always accommodating when it comes to doing tests. The Polymers Center always works with us on figuring out solutions by utilizing more than one method.”
