How to Choose a Metal Chip Processing System – The PRAB Framework

PRAB’s Metal Chip Processing Selection Framework is a structured decision tool for metalworking operations selecting between wringers, briquetters, crushers, and centrifuges. The framework aligns three operational variables, scrap volume, metal type, and fluid content, with the equipment configurations that consistently deliver up to 90% scrap volume reduction, up to 98% coolant recovery, and up to 25% increase in scrap resale […]

Why a Metal Briquetter Alone Is Not a Chip Processing Strategy (And What Is)

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 […]

What 98% Coolant Recovery Really Means for Your Manufacturing Budget

PRAB’s Guardian Coolant Recycling Systems recover up to 98% of spent metalworking coolant and return it clean to your machining operation. For high-volume manufacturing facilities, that coolant recovery rate reduces coolant purchases by 50-75% and cuts haul-away disposal costs by up to 90%, with a documented return on investment in as little as 6 to 18 months. So what does […]

Your Metalworking Coolant Is Costing You More Than You Think – Here’s How to Stop the Bleeding

In a volatile 2026 market — shaped by geopolitical shocks, tariff uncertainty, and rising energy costs – metalworking coolant management is no longer a maintenance task. It’s a strategic financial decision.   Walk through most machine shops today, and you’ll hear the same refrain: budgets are tighter, lead times are longer, and every line item is under scrutiny. Coolant, however, […]

How Brownfield Manufacturing Plants Can Modernize Scrap Handling Without Major Disruption

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 […]

What Is the Best System for Aluminum Chip Recycling?

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 […]

How to Maximize Aluminum Scrap Value

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% […]
