Our Services
Our Service Department performs thousands of metal stitching or metal locking and oven welding repairs every year.  Casting repair is our business. From repairing cracked automotive cylinder heads to fixing a damaged 175,000 CFM blower, LOCK-N-STITCH Inc. will get the job done.  On-site or in-situ as well as in-house machining capability gives us the ability to provide a complete repair package with a guaranty for the entire job. Our casting repair service department is ready to help you:  in our shop, in the field, consulting and technical support engineering.  Give us a call.

When you have us repair your parts, you will benefit from over thirty years of experience.  During these years we have successfully repaired thousands of castings.  This experience is our most valuable asset.  Because of the many different types of parts we've repaired, we have the ability to interlink thousands of individual experiences, successes and, yes, even some failures to develop methods, techniques and processes that work the first time - every time!

Our repairmen are true metal craftsmen.  Each is a skilled machinist and welder.  They are carefully trained in the art of cast metal repair.  Cast iron is our main focus.  It takes a special type of person to do this kind of work.  It can be hard, dirty and very difficult.  Pride in our work is often our greatest reward.  Our intent is simple:  Do the very best job possible.  Attention to details, lots of patience and excellent metal-working abilities have been keys to our success.

We provide two very important services with every job.  Out first effort is to determine the cause of the failure and how to prevent it from happening again.  Second, we engineer the repair to return the part to its original strength or stronger.  By asking If we could have everything we want in this repair, what would that be? we can "reverse engineer." This approach, combined with our experience and passion for our work, results in excellent repairs.   With more patents than any other casting repair company ever, anywhere in the world, more ingenious devices, more understanding of cast iron, we will tell you the truth about what can be done to provide you with the results you need.

Our latest technical breakthrough is a totally new approach to metal stitching called CASTMASTER™.  This incredible new technology utilizes a thread design called Spiralhook™.  These stitching pins draw the surrounding material together to re-establish original strength even in the most difficult conditions.  The CASTMASTER™ technology is the single most important development to date in the history of casting repair.

Our newest product Full-Torque Thread repair inserts will simply solve your thread repair problems permanently and usually better than new, we guaranty it!

Rather than making a hole pattern by chiseling like the method used in the old metal locking process, we utilize a high precision drill fixture to make the hole pattern completely by drilling, to receive the locks in order to assure the best and strongest possible repair. These special stitching pins are used daily by hundreds of repair technicians around the world to perform engine block crack repairs and cylinder head crack repairs.
