This is odd, when you consider that, other than a lot of rain, we don’t see extremes of weather that often. Recently, we’ve experienced what we Brits would regard as some cold weather, although it’s been nothing…

Ask Dr. Nick: Can I fix gaps in a parting line?
A badly fitting parting line is a regular pain in the neck, for a number of reasons. The most notable annoyance is that, as the mold rotates in the initial stages of heating, powder spills out from any gaps that exist. This wastage of powder can cause an under-weight part and, even if the spillage…

Further to Dr Henwood’s comments on Angel Hair, I would like to add the following… Dr Henwood is correct that it is typically formed due to high temperatures in the conveying line.

Ask Dr. Nick: What’s an Acceptable Scrap Rate in Rotomolding?
Recently an ARM member from Latin America phoned in with a technical question and we got into a conversation about the vexed subject of scrap. I appreciate that it’s a bit of a prickly issue and probably not something individual rotomolders would be keen to discuss openly. Not being a molder, I was probably more…
