ARM Technical Director Nick Henwood to Increase Technical Value in ARM

ARM has moved to add significant value to membership in the Association by hiring Dr. Nick Henwood to serve as the ARM Technical Director. This appointment will improve and increase the technical content provided by ARM.

First and foremost, ARM members will see added technical value at our meetings, during our webinars, and on our website. Dr. Henwood will collect technical information from throughout the industry for ARM to disseminate to our members.


Dr. Nick Henwood will add value to ARM’s meetings, webinars, and website in his new role as ARM Technical Director.

Nick’s original degree was in Civil & Structural Engineering, but his PhD studies led him into various branches of chemical engineering. His first involvement with rotomolding came in the mid-80s, while working at Dow Chemical Europe.  He helped to develop Dow’s polyethylene roto grade slate, both technically and commercially.

From then on, he was hooked on rotomolding and, in 1992, he founded a UK-based rotomolding materials supplier, Matrix Polymers Limited.  Over the next 14 years, Matrix grew from a two-man outfit operating from Nick’s basement to a major European materials supply company.

In 2006, Nick sold his shares in Matrix and formed Rotomotive, a training and consultancy company.  Since then he has completed a large number of projects for rotomolder, OEM and end-user clients across the world.

Nick has been committed to the development and dissemination of rotomolding knowledge, through published technical papers and though contributions to rotomolding conferences worldwide.  He served a term on the Board of ARM, as a Supplier Director, in the early 2000’s.

Outside of rotomolding, Nick is a Key Volunteer for a major charity, Cancer Research UK and was recommended for their prestigious Flame of Hope Award in 2015.  He has been married to his wife Helen for 40 years, has 3 children and 5 grandchildren.

ARM is proud to announce that Dr. Henwood will bring his technical insight to ARM and our members.

President’s Message: Farewell Roy and Welcome Nick!


Conchita Miranda

Life always presents curious coincidences…

We announced at the beginning of the year that one of our objectives this term was to have a Technical Director for ARM again.

We had a great one for years: Dr. Roy Crawford, working from Queen’s University at Belfast, served ARM as an extraordinary scientific Technical director.

When he moved to the opposite part of the world and took a lot of new responsibilities, he finished being our technical director, but ARM’s friendship with him never ended.

Roy was an erudite gentleman.  I learned a lot from him, and I am pretty sure that all rotomolders around the world can say the same.  He dedicated his life to research and sharing his knowledge, from Ireland to New Zealand.  From ARM to RotoWorld.  From his lab to the world.  Our industry owes much of our development over the decades to him.

The rotomolding industry worldwide will never forget him.

Last month, already retired and enjoying his free time, Roy passed away.  At the same time, ARM was coming to an agreement with our new Technical Director.  It is like if our dear Professor left his baton to Dr. Nick Henwood.

So, as always in life, sad moments just come with good ones, and hope and excitement for the future make us rise and be optimistic.

Having Dr. Nick Henwood as our new Technical Director will help ARM and the industry to take next steps, to go further, and to grow big.

Dr. Henwood has been involved with rotomolding since the mid-80s and served on the ARM Board of Directors. You can read more about his new role as our technical director here.

Farewell Roy!  Welcome Nick!  Thank you both for being part of this great Association.

Conchita Miranda is the President of ARM and the Director General of Operadora MPK.

Rotomolders’ Heat Wave Suggestions

During today’s Younger Members teleconference, we briefly discussed how rotomolders address manufacturing during the summer. During the 2012 North American heat wave, ARM collected and shared these suggestions from our rotomolder members.

Since that document was published, we’ve heard from multiple rotomolders who publish hydration color charts like this one in their restrooms.

If you have additional suggestions, please share them in the comments field.

Education Offerings in New Orleans

ARM has announced 14 general sessions and eight workshops for the New Orleans Annual Meeting September 24-27. This is in addition to the three keynotes and two seminars that have already been announced.
