Uniboard announced plans to sell its Chatham County, N.C., MDF and particleboard manufacturing facilities to a subsidiary of Chilean manufacturer Paneles Arauco S.A.
The deal, worth $62 million, is expected to close in the first quarter of 2012, according to the company. Uniboard's German-based parent company, Pfleiderer AG, is selling its North American operations as part of an overall restructuring plan for Pfleiderer Group, the company says.
Q: What is ring shake? How do we detect it in our oak lumber? Does this shake cause a bad odor or other manufacturing problems?
A variety of wood glues are used to assemble the 175 pieces in a six-string guitar. Matching the proper adhesive with the application is important for Taylor Guitars.
Q: I have just received some glued-up oak panels that we will be using for tabletops. One of our people noticed that the ends of the panels have developed some cracks and more cracks are showing up every 10 minutes it seems. Most of the cracks are at the glue joint at the end of the panels. The supplier says that our shop is too dry (25 percent to 30 percent RH is what we measure now during the wintertime). My people just checked the MC of many panels, including some that have yet to be unstacked and unwrapped; they are getting some readings as high as 10 percent MC (after correcting for temperature), with a lot over 8 percent MC too. We need an outside person to give us an accurate evaluation.
Q: I have read every Wood Doctor column you have written and have gained a lot of practical information. But here is a question I have not seen addressed before. As background, our fairly large company has really gone into JIT, just-in-time, manufacturing, which means in-process materials cannot sit around very long at all. Well, this has recently translated into machining our glued up panels (edge-glued on a clamp carrier) within 24 hours after they are glued, or sometimes less. Of course, you know what the problem is: sunken glue joints that are obvious after finishing. My suggestion of waiting three days after gluing, as we have always done, has not been well-received. I am hoping that you have some help for us.
The companies in this directory are making investments to make sure that you have the tools and products necessary to develop successful products with lightweight panels.
Q: We are having a problem with raised glue joints in
our solid wood (mahogany) panels and we would like to know what
your recommendation is for the amount of moisture content that we
could get by with, without causing this problem? This applies
also to high-frequency gluing.
The properties of medium-density fiberboard make it a valuable resource for many applications
New MDF line will have production capacity of 226 million square feet on 3/4-inch basis.
What’s next for raw materials prices, and how long will they increase?
