Pulp & Paper
Permanent Thread Repair Solutions for the Pulp & Paper Industry
Unlike all other thread-repair products, C-Serts are guaranteed for the life of the equipment they repair. C-Serts install quickly and easily, between 5 and 45 seconds. They reduce downtime, increase output, and ensure operator safety. In fact, they are greatly superior to the OEM threaded holes of brand-new equipment; here’s why.
What Pulp & Paper Industry Equipment Can Benefit from C-Serts?
Any pulp and paper industry equipment where you frequently install and remove bolts or where vibration or high torque loads cause thread damage can benefit from a C-Sert. For example, a paper machine is immense, with tens of thousands of fasteners that help to adjust widths, thicknesses, and feed rates. The “blind” threaded holes that receive those fasteners can, and do, go bad. The same holds true for linerboard mills, corrugating plants, and box plants. A C-Sert repair eliminates the problem once it’s inserted by cutting and maintaining permanent threads that do not wear with repeated use.
Which C-Sert Product Is Best for the Pulp & Paper Industry?
For 80% of your problems, where an OEM threaded hole is simply worn out, our standard C-Serts solve the problem. The remaining 20% are a different problem, with a different C-Sert solution. In those cases we’ve heard from our customers, the problem is that they’ve already tried to fix the hole with some other brand like a Heli Coil, a Keen Sert, or an E-Z Lok and the repair has failed. Maybe it’s even failed multiple times, and now the hole is too enlarged or worn out for a standard C-Sert. Our “Heavy Wall” C-Serts handle this situation thanks to their larger O.D. Like all C-Serts, they allow you to maintain your original fastener size, and of course, come with C-Sert’s Lifetime Warranty.
How Do You Install a C-Sert?
Every installation breaks down into 2 stages:
- Eliminating the damaged threads. This also creates a pilot hole for the C-Sert. When you use the system we recommend, this takes 12 minutes or less.
- Driving in the C-Sert. This utilizes an impact wrench. It takes from 5 to 45 seconds, depending on the C-Sert’s size.
What Pilot Hole System is Recommended?
Unless you’re making the repair in a machine shop, a magnetic drill is essential. You may already have one, but we offer our own proprietary C-Sert Installation System. It too utilizes a mag drill, but a lightweight one so that one person can quickly and safely make the repair. Our mag drills are made by BDS Maschinen in Germany. Our system’s other components include a 60-degree center to position the drill squarely on the damaged hole, annular cutters to enlarge the pilot hole, and paste lubricant, which works in both vertical and horizontal positions, replacing standard liquid coolant.
The entire system is designed to streamline installation to reduce production downtime. The annular cutters (“slugger bits”) are key because they produce much less tool pressure than a drill bit and thus allow the mag drill to be far lighter and more maneuverable. The result is a perfectly concentric pilot hole in under 12 minutes.
What Tool Is Recommended To Drive In the C-Sert?
Smaller C-Serts (up to 3/4″ and 18mm) can be installed with a large manual ratchet, but we strongly recommend an impact wrench for all sizes, if possible a cordless electric rather than pneumatic. Our C-Sert Installation System offers three different Milwaukee cordless modes: a 3/8”-drive for small C-Serts, a 1/2”-drive for medium C-Serts, and a 1”-drive for large C-Serts. Install times are reduced to seconds.
Whether you make paper or board or are a corrugator or converter, C-Serts will work for you. Our experienced and knowledgeable team will work with you to understand your needs, ensuring you select the right C-Sert for your equipment. Bad threaded holes are your and our common enemy, so we’d be delighted to help you put an end to them, once and for all.
