Custom Channel Insert
Chain channel insert is one of the most common plastic applications in sawmills. With good reason: the channel insert extends the life of chain, reduces the horsepower required to pull the chain and thus reduces maintenance downtime. Plus, compared to other plastic maintenance solutions, it’s quite inexpensive. But did you know Redwood Plastics can supply … Continue reading
UHMW Wear Strip
UHMW wear strip is a common plastic application for sawmills but not all wear strip is the same. The basic wear strip is probably black-reprocessed UHMW because not only is it a cost-effective solution, but the manufacturing process actually makes the reprocessed UHMW more wear resistant than natural! An additional benefit is that reprocessed UHMW … Continue reading
Tivar 88 Wear Strip
When considering new or replacement wear strip in your sawmill or planar mill, Tivar 88 UHMW should be considered*. Many long-time customers of Redwood Plastics already request Tivar 88 after years of excellent performance in their sawmills. Traditionally, cheaper reprocessed-black or natural (white) UHMW is used in wear strip applications; however, Tivar 88 has several … Continue reading
UHMW In Sawmills: Making The Grade
UHMW-PE (ultra-high molecular weight polyethylene) simply known as “UHMW” is the most prolific industrial plastic in many sawmills and has a long history of success in many applications. Along with grades readily available from most plastic distributors, sawmills also utilize several grades where their primary use is in sawmill applications. The following is a primer … Continue reading
Shock, Vibration and Noise
A few weeks ago the Vicksburg Post in Vicksburg, MS ran a story following Anderson-Tulley Lumber Co. Maintenance Manager Mike Williams through a typical work day and asked him about the challenges he faced in the mill. The article describes the noise and vibration of the modern mill – something we know our readers would … Continue reading
Sharp Chain bed
One custom solution supplied by Redwood Plastics for sawmills is the sharp chain bed. The plastic bed (made of UHMW or nylon) replaces a metal bed and results in less wear on the chain. Lubrication requirements are reduced by up to 75%. In order to manufacture the bed, we require either a dimensioned technical drawing … Continue reading
UHMW vs. Steel Flights
Many plastic applications in sawmill and planarmills that we promote here are innovative solutions that are readily noticable: bushings made of proprietary materials, the Shark Fin System, Hi-Temp kiln cart bushings, and urethane Deadplate. Solutions which stand out amongst other equipment in the mill. However, one application that does not get enough attention are UHMW … Continue reading
Nylon Hard At Work
Cast nylon is a plastic that should not be overlooked in sawmill applications. Nylon is able to bear a large amount of load compared to other plastics, especially UHMW and PTFE but is readily available and reasonably priced. Nylon applications have actually been increasing in the mills over the years, one notable example is nylon … Continue reading
One Tuff Wheel
We had an interesting inquiry a few weeks ago. A sawmill maintenance manager in the U.S. Northeast was using UHMW carriage wheels and they were wearing out extremely fast. We ended up referring them our parent, Redwood Plastics, to look into a solution – and they didn’t have to look far. Redwood offers a type … Continue reading
