Q: What is a Profit and Compliance Platform for metalworking operations? A: A Profit and Compliance Platform is an integrated way to manage the three waste streams every metalworking plant produces- metal scrap, spent cutting fluids, and industrial wastewater- […]
Metal chip briquetters get a lot of attention, and for good reason. Compressing loose turnings into dense, dry briquettes increases the value of metal scrap, reduces hauling costs, and recovers cutting fluid that would otherwise be lost. Any shop generating significant volumes of aluminum, steel, copper, brass, or cast iron chips should be evaluating briquetting as part of its scrap […]
Brownfield manufacturing plants can modernize scrap handling without major disruption by upgrading existing systems in phases rather than replacing everything at once. For many facilities, aging conveyors, manual chip handling, forklift traffic, coolant loss, and inefficient scrap load-out processes create hidden costs every day. The most effective modernization strategy is one that improves productivity, safety, and recovery value while integrating […]
Aluminum chip recycling is one of the most effective ways manufacturers can recover value from machining operations. For companies machining aluminum, chips and turnings are not just waste—they are a reusable asset. Yet many facilities still lose profit by hauling wet chips, storing bulky swarf, paying excessive freight, or allowing reusable coolant to leave with the scrap. The best aluminum […]
Stop Leaving Money on the Table – How to Maximize Aluminum Scrap Value with PRAB’s Briquetting and Conveyor Systems Most metalworking operations think about aluminum scrap the same way they’ve always thought about it — as a byproduct to manage, not an asset to optimize. In previous years, that mindset was understandable. Today, with aluminum prices up more than 46% […]
There’s a smell that anyone who has worked in a machine shop knows. It shows up on Monday mornings after the machines have been sitting idle all weekend. Dirty Coolant Costs, and it smells somewhere between rotten eggs and sour milk, and by mid-morning, you’ve stopped noticing it — which is part of the problem. That smell has a specific […]
There’s a calculation most manufacturing operations never run. It goes like this: take the machining scrap pounds of copper, brass, or bronze chips your facility generates per week, multiply by the current scrap price ($3.40–$5.10/lb depending on grade and cleanliness), subtract the discount your scrap dealer applies for oil contamination and loose bulk, and compare that to what you’d earn […]
Aluminum has dominated the commodity headlines this spring — but copper prices have been quietly building a more consequential story. While aluminum’s challenge is supply: mines capped, smelters disrupted, capacity maxed — copper’s challenge is something fundamentally different. It’s demand. Demand that no amount of new mine construction can keep up with, demand from industries that didn’t even exist a […]
In industrial manufacturing, the label “systems integrator” sounds like a compliment. And in some contexts, it is. But when that label causes buyers to underestimate a supplier’s depth of technical expertise in specific, high-stakes applications, it becomes a liability — for the buyer. PRAB is frequently positioned as the company that connects the pieces: conveyors, chip processors, fluid recyclers, wastewater […]
