With the opening of our new polyethylene plant in Monaca, USA, Shell Polymers has hired 60 polymer experts, aka Polymer Pioneers and Polymer Pros, who have a proven track record in polyethylene. In this profile, Technical Service Engineer Elliot Carnevale shares about his role and reveals his top four injection molding technical tips.

A Day-in-the-Life of a Technical Service Engineer

According to Elliot, a Technical Service Engineer, “Solves customer problems. Prevents customer problems. I prefer a fundamental approach to problem solving, so I look at the part design, mold design, process and material to develop a list of possible variables driving the issue. These principles were further reinforced when I completed the American Injection Molding Institute’s Plastics Technology and Engineering Certificate Program earlier this year.”

Elliot’s Top Four Injection Molding Tips

  • Make sure you’re running the most appropriate resin.

    It is quite common for injection molders to become comfortable running a specific resin and they often extend its use to multiple applications. But that can result in overengineered, more costly parts. I think there’s a real opportunity for converters to look at each application critically, and with an open mind, before deciding on what material is most appropriate.

  • Defects aren’t usually caused by a single problem.

    Most injection molders experience some defects and processing issues and, when problems occur, it can be a mistake to look for a single cause. Engineers will typically hunt for a magic bullet and, when they find it, assume that it will solve all their future problems. In my experience, it’s far more likely the result of multiple variables combining.

  • Running hotter doesn’t overcome many pressure-related issues.

    In injection molding, shear has a far more significant impact on the flow behavior of a material than the temperature of the barrel. Higher shear generally means lower viscosity. So, consider your screw design, your injection velocity and the diameter of your flow channels.

  • Simulation is an injection molder’s best friend.

    If you are not already using simulation, it can be a hugely valuable tool because it avoids the need to iterate on the press. Instead, you get to understand the impact of different variables at the click of a button.

An Unrivaled Customer Experience

Even though Shell Polymers is still preparing its new plant for start-up, Elliot is already focusing on our future customers’ needs. In a technical service engineer role, Elliot serves as an advocate for our customers when they’re not in the room, and he works to do that every day. That’s how Elliot strives to create an unrivaled customer experience.

There’s a number of things that sets Shell Polymers apart from other suppliers but the application hall is one of the most significant. Outfitted with state-of-the-art, industrial-scale equipment that is available for our customers to use for prototyping and materials evaluation, it will be unlike anything else in the polyethylene industry.
