Edel, our Indonesian colleague, came to Phnom Penh for a training on ICS production, learning from the Cambodian team the best practices and lessons learned

Edel now works for YDD (Light of the Village Foundation, Indonesia) and will facilitate support to local stove producers in order to deliver better quality products.

And this is the moment when we have to transfer knowledge from a project to another…

To offer our partners on the field the most relevant and appropriate training, we facilitated knowledge exchange between Edel and Narith; a stove expert at GERES. The aim was to improve Edel’s design and production capacities, and to transfer knowledge to him to be able to advise and strengthen the Indonesian producers’ skills on this particular topic.

Narith has worked for GERES since 2004 and is now a Technical Operation Coordinator. As an expert, he trained Edel on designing internal moulds, drafting ideas on the detail of the retractable blade mechanism, designing in Autodesk Inventor "parts only" in 3D, assembling the parts, drawing parts in 2D and exporting to PDF.

They began their training sessions at the GERES office in Cambodia in a hands on way that allowed  Narith to show Edel the mould designs in 3D on his computer.

Then, they went to the field to put theory into practice. Edel was able to plan, calculate and build his own moulding sets (external mould, mould for pot rests, moulding stove, moulding axis…) and can now produce entire moulding sets for improved cookstoves from scratch. To completely understand how to produce it, a first set was built by the trainer (Mr. Hun Hai) as a demonstration and a second one by Edel for practice. Through the support of 3D models presentation, they could explain more in-depth all the characteristics of the moulds.

What is important to understand is that there is not only one mould to make but several. For example, to make the top mould, you need another one.

In addition, it was important to take in account the Indonesian conditions like clay shrinkage, Indonesian habits, etc.

Though time was short, Edel learned to the maximum and the challenge was quite big. At the end, Edel managed the effect and importance of clay shrinkage, conducted tests to determine the shrinkage factor of Indonesian clay, calculated proper moulds dimensions to get required stove dimensions, built a set of moulds required to make an NLS including grate punching, adapted sets of moulds to another stove design, including grate punching, trained producers on making moulds sets and trained producers on moulding stoves.
