Mold Repair & Restoration
Production downtime is expensive. We deliver precise, efficient mold repair to return tooling to production with minimal disruption.
Whether the mold was built by us or another shop, we evaluate wear patterns, mechanical failure points, and part quality issues to determine the most effective repair strategy.
Our capabilities include:
Core and cavity repair
Slide and lifter repair
Ejector system repair and replacement
Gate and runner modifications
Surface refinishing and polishing
Flash and wear correction
We embrace complex or unconventional projects
And more!
Mold Diagnostics &
Troubleshooting
We regularly service molds built by other tool shops that are no longer running properly. We identify why the tool is underperforming and provide a clear, practical path to restore reliable production. Our diagnostic services include:
Mold inspection and condition assessment
Root-cause analysis of part defects (flash, short shots, splay, dimensional drift, etc.)
Alignment and shutoff evaluation
Mechanical timing and function analysis
The Advantage
of a 3D Mold Model
A current 3D mold model helps reduce diagnostic time and overall repair costs. With a digital model, we can quickly verify clearances and shutoffs, design replacement components faster, and minimize teardown and reverse-engineering work.
If a model is not available, components must be reverse-engineered as needed, but providing a 3D model typically lowers total costs and shortens lead times.
Hot Runner & Manifold Service
We provide in-house hot runner support and can coordinate qualified external service providers when manifold boring or deep cleaning is required.
Heater replacement
Thermocouple replacement
Wiring inspection and correction
Component troubleshooting
precision micro welding
We offer precision micro welding for controlled material build-up and dimensional restoration on hardened tool steel components. This process allows targeted repairs with minimal heat distortion, making it ideal for shutoff restoration, rebuilding worn steel, feature modifications, material build-up for re-machining, and extending tool life.
For major structural weldments requiring certified procedures, we coordinate with qualified partners as needed.

Complete Mold Disassembly
All moving components are carefully disassembled to allow full inspection of wear areas. Slides, lifters, and ejector assemblies are removed so critical surfaces can be evaluated and serviced before problems occur.
Cleaning & System Service
Each mold receives a thorough cleaning to remove resin buildup, debris, and plate residue. Vents are cleared to maintain proper airflow, and accessible water circuits are cleaned to ensure consistent cooling performance.
Mechanical & Wear Inspection
Critical components are evaluated for wear and performance. This includes inspection of shutoffs, slides, lifters, springs, ejector pins, and return systems, along with verification of hardware torque and mold detail condition.
Reassembly & Functional Verification
After inspection and servicing, all components are cleaned, lubricated, and reassembled. Mold timing and alignment are verified, followed by a final operational check to ensure the mold is ready for reliable production.
