Metal Stitching Process Of Repairing Metals

Metal stitching and casting crack repair are cold repair process of mending metals and increasing their longibility and strength. It is done basically because of the need for an alternative to the difficulties encountered in welding.

Metal stitching is a cold repair process. Permanent repair of any Crack/Broken part of cast item like Gear Box Housing, Turbine Casing, Engine Block, Cylinder head, Crank Casing, etc. Metal stitching or metal locking as it is called in some parts of the world, have become generic phrases that describe methods of repairing cracks in cast metals without welding.  Why metal stitching?  Well, primarily because of the need for an alternative to the difficulties encountered in welding. Cast iron is the most difficult of all common cast metals to weld. Most electric welds with nickel rod on cast iron fail.  Most cause more damage than was present before the attempted weld. And there is a lot of time and effort involved in the clean-up and machine work of any welded piece.

Casting is the act or process of making casts or moulds. Casting crack repairs is the process of repairing cracks in the metal or a stone. The procedure for repair will include dressing the damage and applying fresh material to achieve the desired finish and shape, covering the repair with a wet rag and/or plastic cover, and then taking steps to blend the repair into the adjacent areas

Eka-Press Techno Service PVT Ltd. is a metal stitching, cross rail machines and crack forging machine repair centre. Established in 2004, ETS is the engineering services provider of the 21st century. It is an organization of professional and technocrats with several years of hands on experience in the technical services sector. The skilled technicians of ETS have worked all over the country, under the most demanding conditions. It is best known for its metal stitching technique.  For metal stitching, locks are inserted into the precision slots layer embed into the casting two sides together and the crack is closed by puling action of the high tension locks.

Many different concepts have been tried over the years and most have been called metal stitch or metal lock. A main part of the process that replaces the crack itself is the stitching pins. Many repairs may require using only stitching pins such as in cracked cylinder head repairs and cracked engine block repairs. Often large industrial repairs with structural damage only that don't require sealing the crack can be repaired with Locks only. The products developed and patented over the old metal locking process have been used for hundreds of thousands of successful repairs in many industries.

Along with metal stitching this company provides other services such as casting crack repairs, crack engine repairs, broken engine repairs, cross rail machine repairs and crack forging machine repairs. Reasons for why metal stitching should be done? Cold repair causes no distortion on work piece; it is a leak proof repair, it can withstand pressure up to 75kg/cm2 and temperature 1000cc and improves the tensile strength of the material.
