“Are gray iron foundries sustainable? What about cast gray iron products in general?” These concerns resonate strongly with many of today’s foundry customers. Whether you’re seeking to minimize the carbon footprint of your products or you’re just trying to keep on top of ever-stricter environmental regulations, sustainability is seen as increasingly important throughout the modern manufacturing space.
At Acme Foundry, Inc., our 120-long legacy in Coffeyville, Kansas since 1905 blends tradition with efficiency to deliver sustainable casting solutions that benefit both the environment and our customers’ bottom lines.
Acme’s Commitment to Casting Quality and Sustainability:
Green Sand Molding – A relatively sustainable foundry process, offering manufacturing flexibility and scalability with minimal resource overhead.
Integrated Core Room – In-house sand core fabrication ensures dimensional accuracy and reduces rework, improving yield and reducing waste.
Defect Mitigation Systems – Techniques targeting shrinkage, blowholes, sand inclusions, and other casting defects keep rework low and quality high .
Integrated CNC Machining – The Magic Circle Machining division streamlines post-casting workflows, diminishing transport and redundancies.
ISO 9001:2015 Quality Management – Our ISO 9001 certified quality management system ensures consistent performance, minimized defects, and optimized processes across all operations.
Acme’s Lean and Green Gray Iron Foundry Processes:
Efficient, Cost-Effective Casting with Green Sand Molding
Acme leverages green sand molding, a traditional process that remains both economical and agile. Crafted from olivine sand, bentonite clay, water, and a small portion of additives, green sand is cost-effective, widely available, and adaptable to complex shapes. This simplicity allows quick setup, high capacity runs, and minimal tooling, contributing significantly to material and energy efficiency.
Material Properties that Support Sustainability
Gray iron’s thermal stability allows castings to withstand extreme temperature changes without fracturing. Outstanding compressive strength makes for durable, long-lasting products. So the material inherently minimizes damaged products and waste. Furthermore, gray iron’s excellent vibration damping (low NVH) also not only enhances user comfort but reduces energy waste in machinery, slightly adding to its green material properties in industrial applications.

Lean, Integrated Foundry Practices
Acme integrates core making, molding, casting, and machining (via our Magic Circle CNC machining division) within one lean workflow. This integration minimizes transport, scrap, and energy waste, delivering operational efficiency that’s both cost-effective and environmentally responsible.
Rigorous Quality Control Reduces Scrap
A robust quality assurance framework in accordance with ISO 9001:2015 certification helps Acme reduce waste by ensuring accuracy at every stage. From pattern inspections to defect prevention strategies (managing shrinkage, blowholes, inclusions, etc.), this vigilance avoids costly rework and material waste.
Resilient Domestic Supply Chain Reduces Carbon Footprint
By producing domestically, Acme avoids the carbon-intensive and unpredictable nature of overseas shipping. Acme’s ability to deliver promptly, maintain inventory agility, and collaborate closely with each client further enhances the sustainability and responsiveness of our casting services, along with your ongoing supply chain.
