A manufacturer that produces laminated signs contacted EXAIR for a blow off application. Being that we are experts in this area, I thought this would be a simple solution. The conversation started out about the signs that they manufacture. They are laminated sheets that have a thin aluminum film with a coating on the front and back sides. Their process was to cut stacks of these signs that he called books to specific dimensions. Here is how the conversation went in a shortened version:
- I need to blow off chips from the saw process.
- It has to be strong enough to remove the chips that are melted into the face of the laminate.
- When the blade gets dull, the chips become hotter. The operator has to blow on the blade as it is cutting to reduce the amount of chips that melt into the laminated face.
- After the machine finishes and the books are removed, the table lifts up and disposes of the excess chips.
- Model 1122 2” Flat Super Air Nozzle to blow a wide area off the top of the signs after sawing.
2. Model 5330 High Power Cold Gun with dual point hose to place on the saw blade. This will extend the life of the blade and help keep the chips cool. Eliminating the melting into the face.
3. Model: 110248 Super Air Knife Kit to blow the chips from the table after it is lifted.
As you can see, with a simple initial question, it became complicated rather quickly. Instead of looking at one area of the application, I was able to improve their entire process. In any manufacturing plant, scrap and downtime are the two biggest culprits in reducing profits. The scrap occurred when the faces were scratched and damaged. The downtime happened during the cleanup between book change-overs and when the saw blades were being replaced. Overall, their process improved in efficiency and speed.
