Adriana Velasquez

Technical Service Engineer | Rotomolding

With the opening of its new polyethylene plant in Monaca, USA, Shell Polymers has been hiring a team of industry experts, aka Polymer Pioneers and Polymer Pros, who have a proven track record in PE.

Senior Technical Service Engineer Adriana Velasquez shares about her role at Shell Polymers and reveals her top four rotational molding technical tips.

Adriana has more than 10 years’ experience of helping customers to innovate in pipe applications and resolving technical issues in rotational molding. In July 2020, Adriana was also named the Vice Chairwoman of the Plastic Pipe Institute's Power & Communications Division.

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

Adriana explained, “Most of my day is spent attending to our customers’ technical issues, answering their questions and running trials and tests to address their needs. I am also Shell’s representative in external standards, certification and public safety organizations, including ASTM, and industry organizations such as the Plastics Pipe Institute and the Plastic Pipe and Fittings Association, of which I am the Technical Committee Vice-Chair.”

 

“A deep understanding of our customers’ goals is vital to enabling them to achieve their objectives”

Adriana’s Top Four Rotomolding Tips

  • 1. Take care when you transport resin from silos.

    If there are too many 90° elbows, the resin may develop “tails”, “angel hair” or what some people call “bird’s nests”, but these can be avoided with proper control of the equipment and lines used to move the resin.

  • 2. Select your additive package carefully.

    People need to remember that not every additive package will give you everything you need. Too much of one additive can affect the product attributes conferred by others. Therefore, I suggest selecting an additive package that meets your needs and maximizes your product’s key attributes.

  • 3. Optimize your water-to-air ratio during cooling.

    It’s always better to use water and air mist during rotational molding for faster cooling, but do not add too much water because it may act as an insulator and thus increase the cooling time and overall cycle time.

  • 4. Run thickness experiments when using a new mold.

    During rotational molding, the thickness will help to determine the optimum major and minor axis speeds and ratios. 

An Unrivaled Customer Experience

A deep understanding of our customers’ goals is vital to enabling them to achieve their objectives. Adriana meets with them frequently to learn about their processes, what they are working on and what their goals are. Then, she provides them with a realistic timeline for the tasks necessary to address their issues or projects, and ensures we deliver on time.

The location in Monaca could be really valuable for customers because it’s right in the backyard of much of the current North American PE industry. That means Polymers will be able to get product to most customers quicker than suppliers located on the Gulf.

It also means that it will be easy for them to come and use the equipment in our application hall, which will be on the same site and will house cutting-edge analytical and product application equipment. They may be able to avoid shutting down their own lines by using this for testing or troubleshooting.
