So what if one saw cuts faster than another?: Cutting speed is not the same as process efficiencyTwo similar saws might have significantly different cutting speeds, and given a choice, most fabricators would choose the faster saw. However, the saw's speed isn't the only factor that affects efficiency. Material handling before and after the cut also plays a big role in process efficiency. Fabricators who overlook material handling don't gain all they can in terms of increasing throughput.

Long loads, narrow aisles, easy access: Side-loading lift truck handles cumbersome products in confined spacesSince starting with just one warehouse in 1989, J G Kelly Supplies has grown along with Ireland's booming construction industry. Limiting factors such as the warehouse's doorway width, narrow aisles, and 90-degree turns meant the company had to rely on manual labor to handle the long, cumbersome items in its inventory. A standard forklift was out of the question. The company eventually purchased a multidirectional side-loading lift truck from Combilift for moving inventory in this challenging environment.

Better safe than saw awry: Contract manufacturer promotes safety and gains efficiency by relying on lift truck and new saw loaderWhen a machine operator cut a bundle of barstock open to load into a saw, the bands popped, moving the blocks that were put there to safely contain the bars. The bars fell on the operator's foot and trapped it. Not wanting to duplicate that nightmare, engineers at Kirsan Engineering, Kenosha, Wis., set about to create a method of loading barstock that relied on lift trucks, not cranes.

Pallet changer, tower, or shelving system with that laser?: Options for storing, transferring materialsWhen fabricators decide to automate material handling in their laser cutting operations, they have several choices to make. The decision on whether to automate—and what kind of system makes the most sense—will depend on the shop's capabilities, its production capacity, and available floor space. The options cover the full spectrum, from basic systems that simply unload one pallet and bring in another to large racking systems that maintain a full inventory of raw material and cut parts and can transfer those parts to other machines in the shop.

New press? What will you do with the scrap?: 5 ways to plan ahead to avoid costly surprises around the bendScrap handling is one important issue that is sometimes left out of the planning stage, but if not integrated into the project properly, scrap handling can cost you operating time and money. By asking—and answering—these five questions first: Can I install the equipment in the floor space I have? Do I want to drop the scrap through the bolster or convey it away from the bolster? Do I want to convey the scrap to a central collection area or near the press at floor level? What size pit do I need and how will I collect the scrap when it gets to the remote scrap area?—you can prevent costly problems.
