Keystone Automation offers assembly and rebuilding of your machinery. We have a very experienced workforce who knows how to take something apart, fix it, and then put it back together. We build all sorts of machines that our engineering group designs. We have built and rebuilt everything from hinge drilling machines to book cutting machines.

6 to 8 Drill Retrofit

We were contracted to change a machine that drilled holes through 6 pre-formed hinges to one capable of drilling 8 holes. We did a ground-up restoration on it. Everything was removed, cleaned and inspected. The frame was sent out for powder coating. We even cleaned out the indexing table. We upgraded safety controls, cleaned up the hydraulics and even installed a new drive motor. Changing to an 8 station drill gave them a 33% increase in productivity. Rebuilding the machine ensured it would continue to work reliably for a long time.

Chain Guides

We built these chain guides for one of our local customers. They are used to transport heavy objects and needed to be heavy duty.

Collator Rebuild

We rebuilt a collator machine for a customer. A collator uses vacuum cups to feed sheets of paper onto a lug chain. One page is fed on top of the other and by the time they get to the end you have a book or pamphlet. This machine was built in the early 1970’s. We didn’t take “before” pictures. In the “after” pictures, however, it looks like a new machine. It functions as well as the day it was made.

Modu-Dense Tanks

We have been assembling tanks for one our customers since we first opened our doors. We receive the tank and the valves from a vendor. We supply the pipe, fittings, electrical and pneumatic panel and assembly. The 5 tanks on the truck went to Peru. They are installed underneath a silo and are used to control flow of bulk solids to a pneumatic conveying system.

Ream Wrapper Rebuild

We rebuilt this machine for a used machinery distributor. It puts a wrapper around reams of paper. The paper is fed in one side. The wrapper sheets are fed in the other. A wrapped ream comes out the end. This machine dates to the late 1970’s and was in pretty rough shape when we got it. We also needed to adapt an elevating sheet feeder to it – something it was not designed for. We tore it down to a manageable level and inspected everything. Parts that were severely worn such as the shaft shown in the pictures were replaced. We inspected everything, cleaned it up and reassembled. The finished pictures tell the story of how nice it came out.

Trimmer Rebuild

We were contracted to rebuild a Wohlenburg 3 knife trimmer. It came to us in pretty good shape at first glance. We cleaned up the electrical and looked things over closely. What we found was scary. Someone before us had repaired a cam and left the metal shavings in the track. We also found that the main pusher arm was held in place with a set screw – not pinned. The more we looked, the more we found. When you have experienced mechanics doing what they do best, the results are amazing.
