Repair Metal Stamping Parts: Welding

Many worn, cracked and broken parts can be repaired and returned to productive service. If needed parts can be reverse engineered and made new. We have refined our steps and procedures over the years to provide the highest quality press repair welding services in the industry. REPAIR METAL STAMPING PARTS: MACHINING We provide CNC machining capabilities including; lathes, VTL, saddle mills with 4″ ,5″ & 6″ spindles and floor milling. On site machining includes milling and line boring capabilities.

MER Corp has been a valued resource for industrial customers in far-ranging industries such as robotics, defense and locomotive, to provide high-quality weldments for mission critical applications, such as tool and die repairs. Unlike our competitors who perform tool and die repair as a sideline, our company focused on this welding operation from our inception. In fact, we have the expertise and capabilities to not only repair, but address concerns of build-up and hard facing on parts up to 10 tons. We incorporate a thorough repair process that ensures every aspect of the repair is addressed on die parts that include injection molds, hand transfer dies and single-hit, progressive or transfer stampings. Our experienced team of machinists and welders disassemble and inspect the part to determine what machining and fabricating is required to return the part to working condition. For parts requiring replacement, our large selection of materials including stellite, titanium and stainless steel guarantees the part is repaired to withstand the rigorous demands associated with these tools in accordance with customer specifications. Because of our versatility and expertise, we can make repairs in small areas while avoiding build up. However, we can also improve and add build up on shafts that were turned too small. To learn more about our tool and die repair services or discuss a potential repair project, see the table below or contact us directly.
  • Sharpening and reconditioning – To ensure the production of quality parts and preventive maintenance of tooling
  • Component replacement – To replace a broken die component quickly and effectively, using customer component design data or reverse engineering.
  • Die changes – To re-manufacture a die to customer specifications when a change is required
  • Quality work – To make a repair accurately the first time, in keeping with our industry-leading quality standards
  • Quick turnaround – To make rapid, effective die repair and engineering changes
