Radco Industries has been applying adhesive and gasket materials for years. Depending on the process requirements, we can apply
two–part chemicals hot melt	anaerobic gaskets super glue

Using:
silk-screens transfer pads	Multi-axis CNC robotics

To shorten cycle times, we…

• design/build oven and conveyor systems to speed the curing process. 
• design/build operator assists or automatic unloading systems.

To further shorten cycle times...

• Our systems are designed to handle multiple sized parts with different bead patterns using little or no change over tooling.

Some dispense equipment manufacturers we have worked with:
Nordson Loctite	S.E.E. Kern Liebers

At Radco Industries, we specialize in a broad array of custom design/ build equipment with automation solutions including assembly, adhesive and gasket dispense, CNC and indexing dial machining systems plus more. We have full in-house conceptual, mechanical and electrical design capability.

Customer Problem: Due to improper installation and the condition of the gasket upon delivery, the customer was having field failures of its electrical conduit fittings.  In addition to the failures the high cost of adhesive backed gasket material and the waste associated with die cutting the gaskets from this material led the customer to find a new solution.     Our Solution:  We designed and fabricated a robotic “form in place” gasket cell which is a two-part catalyzed urethane foam gasket. The gasket cell consists of a three-position rotary index table with quick change UHMW tooling nests for the 13 parts. The nests hold from 1 to 36 parts per pallet, depending on size. The operator loads at station 1, the table indexes to station 2 where the Fanuc 710iB, dispenses the liquid urethane gasket utilizing a sophisticated two-part meter mix system. The air entrained catalyzed urethane begins to rise as soon as dispensed. On completion of the dispense, the table indexes to station 3 where a Fanuc LR 100iB with quick change vacuum pick up heads lifts an entire row of gasketed parts and accurately places them onto our custom designed and built 36”x18-foot cure conveyor with special high humidity section and 170 degree F infrared curing. The finished/cured parts will drop into the finished goods bin. Cycle time for the robotic “form in place” gasket cell is approximately 4 seconds per part. Through the entire process, a single operator performs all operations. Change over uses no tools and is extremely quick, requiring only the changing of the three slip-in- nests and the vacuum cup head. This gasket cell generated an annual savings of approximately $600,000 for our client as well as a significant quality improvement.

 

Customer Problem: A lean directive added problems to an already difficult task on a high mix / short run production cell applying adhesive to a filter media and caps.  Multiple pieces of tooling, slow process time and increasing operator injury due to repetitive motion pushed the customer to find a new solution.  The customers’ internal processes also required a vendor willing to work hand and hand throughout the process to ensure every level of the organization was “on board” with the new work cell.   Our Solution: Using feedback from the customer’s staff including engineers to their operators, we developed a cell with no change over tooling and no down time between production runs.  The operator simply swipes a barcode with the production order causing the cell to request dimensional information from the plants data server.  A servo slide adjusts to accommodate the new parts ranging from 2 to 20 inches and applies a bead of adhesive to the part.  The parts are indexed through an oven for curing and released to an operator for the next process.  To reduced operator stress the parts are lifted up to a comfortable level. The process also includes applying round caps to the part coming off of the first machine.  These caps range in size from 1 ½ inch to 6 inches, using an automated self sizing chuck the machine applies adhesive to the caps.  The operator assembles the caps and places the unit into a second curing oven.  Again the parts are lifted up to a comfortable level to reduce operator stress.  A total of nine servo motors and three dispense systems were integrated on the cell.
