Screw & Barrel Repair and Rebuilding
When feasible, making the decision to repair or rebuild your feedscrew or barrel can provide a substantial cost savings and extend the useful life of these vital parts. 
We can usually let you know if this is an option by assessing your screw or barrel with an on site inspection or by viewing photos. If your part is damaged or worn beyond repair we can manufacture a new barrel or new feedscrew that meets the appropriate specifications.

Rebuilding Process
Inspection & Assessment
Every feedscrew repair or rebuilding job begins with a visual feedscrew inspection and physical measuring of critical dimensions to assess the feasibility of a repair.
The results of the inspection are compiled and then reviewed by our engineering team. If the assessment is favorable for repair or reconditioning a cost proposal is prepared. You will then be contacted with the feedscrew repair cost or advised that the feedscrew cannot be salvaged.
If Repair Is Possible
Upon your authorization to proceed your feedscrew will be thoroughly reworked. Repair and reconditioning steps include:
- Stripping any plated finish
- Surface prep and plasma arc welding to replace lost hard facing material (steel)
- CNC machining to reshape the feedscrew to proper tolerances and required specifications
- Application and polishing of the final finish
All rebuilt feedscrews are given a final quality check to assure acceptable tolerances and error free work. Your feedscrew is then shipped to your destination.
We offer expert field services for the removal of stuck feedscrews and installation of rebuilt or new feedscrews.
