Die Maintenance and Repair for Reliable Stamping Production
Wisconsin Metal Parts provides die repair and preventative maintenance services to extend tooling life and ensure consistent performance in metal stamping operations. Proper die maintenance is essential to keeping production running smoothly and producing conforming parts over long production cycles. We support both routine maintenance programs and full die repair services, helping manufacturers reduce downtime, control costs, and maintain part quality.
Preventative Die Maintenance Programs
A structured preventative maintenance (PM) program is key to maximizing the lifespan and performance of stamping dies. Our maintenance programs are designed to:
- Monitor wear on critical tooling components
- Maintain cutting edge sharpness
- Identify high-wear areas early
- Predict maintenance intervals based on production data
- Reduce the risk of unexpected tool failure
Preventative maintenance also establishes clear inspection criteria, allowing operators and quality teams to recognize early signs of wear before defects occur. Maintaining detailed maintenance logs allows trends to be tracked over time so future servicing can be planned ahead of production schedules.
Die Repair Capabilities
We provide full-service die repair capabilities through our in-house tool and die shop, ensuring fast turnaround and consistent quality control. Die repair services include:
- Sharpening cutting edges
- Replacement of worn or damaged components
- Repair and reconditioning of tooling assemblies
- Adjustment and alignment of die components
All design and manufacturing work is completed in-house, allowing for tighter control over quality, lead time, and repeatability.
Tryout & Validation
After maintenance or repair, it is critical to verify that the die is performing as intended. We utilize tryout presses up to 200 tons with full feed lines to validate tooling performance and confirm that parts are being produced to specification. This process helps identify any necessary adjustments before the tool is returned to full production.
Reverse Engineering & Tooling Support
When design data is unavailable or outdated, we can reverse engineer existing tooling components to support repair and replacement.
We can work from:
- CAD files
- Paper drawings
- Existing physical components
Additional testing can be performed to determine material type, hardness and any potential coatings. This ensures replacement components match original specifications and perform as required in production.
Quality Assurance & Certifications
All die maintenance and repair work is completed under controlled quality processes to ensure tooling performance and reliability. As an ISO 9001:2015 certified and ITAR registered manufacturer, we meet strict quality and security standards. Our cybersecurity systems are also aligned with NIST SP800-171, ensuring safe handling of sensitive data and export-controlled information.
A part print and inspection report for the parts that the tool is making is a great place to start. The last parts the die made and the coil end strip are also helpful for the tool makers to investigate the tool and determine what needs to be done for die maintenance. If these things are available, we request that they accompany the tooling when shipping to us.
It is good practice to identify high wear items in stamping tooling and keep some spare components in your maintenance department. We can make spare die components and keep that CAD info on file for future use.
We have a variety of options for reverse engineering. The simplest form is using hand held measuring instruments to verify sizes and transfer that data into a CAD drawing. We also have several CMM’s, laser scanning and vision systems that can be used to capture the needed information. Models can then be created using Solid Works and 2-D part prints from those models. We have additional local support for 3-D scanning and material & coating analysis, if needed.
