Gas metal arc welding is an effective method for joining thin-gauge materials-- from 24-gauge to 0.1875-in. carbon steel and 18-gauge to 0.1875-in. stainless steel. But extra attention should be paid to the equipment and the welding technique to minimize burn-through and distortion.
Selecting the press brake and tooling for a job involves much more than just making sure there’s enough brute force. You need to calculate how much tonnage the job requires, then determine the best machine and tooling to handle the tonnage.
Carter Day International punches thousands of holes to make specialized screens. One screen can take several hours to punch. Problem is, the company doesn’t have enough volume to warrant using a specialized perforation press. So it uses a traditional turret punch press, but with highly durable tooling.
Blast cleaning can be an extremely effective way to prepare a part for coating. But if the machine isn’t set up, maintained, or monitored properly, the operation can go awry.
A fabricating shop floor can be a very dangerous place even when all types of safety precautions are taken. Fab shops that ignore safety are putting their employees--and ultimately the business--at great risk.
Manufacturers have many green options in their choices of lift trucks, including low- or no-emissions, energy-efficient forklift technologies. Raymond, Toyota, Nissan, Hyster, Yale, Power Designers, Minit-Charger, and AeroVironment weigh in on how today’s lift trucks meet demands for lower emissions, higher energy efficiency, and CARB and EPA emissions standards.
In the Japanese language, monozukuri means "the way something is manufactured." Japanese fabricators realize that it is the means by which they consistently make quality parts and keep ahead of international competitors.
An automobile enthusiast since he has a youngster, Ariel Banco started developing custom-made air intakes after he graduated from college. Eventually he had such a backlog that he quit his professional career to become a full-time fabricator, making air intakes for automobiles, motorcycles, and occasionally airplanes and personal watercraft.
In the early 2000s, Innovated Machine & Tool Co., Newport News, Va., tried a robotic press brake for a bending job and found that it worked out well--for that job. Unfortunately, when the contract ended, so did the useful life of that robotic press brake. Since then, the shop hasn't had to worry about machine obsolescence because its panel bending technology is helping it stay on top of all sorts of bending work.
Shops start improving by measuring and documenting what they already do, because they can’t improve what they don’t measure.
In 2004 tax regulation changes significantly expanded the credit opportunity associated with the Research & Development Tax Credit. Today the credit is accessible to many small and medium-sized companies whose activities include design, manufacturing, and process improvements.
In this eighth installment of columnist Gerald Davis’ series on job estimating, he delves into tools for improving the estimator’s crystal ball.
We all know about situations in which we spend money and yet nothing improves or even gets worse. But when you do continuous improvement right, you’ll get better financially and see a strong return for that investment.
