Green Sand Iron Castings
Strength, Versatility, and Expertise at Plymouth Foundry
Plymouth Foundry is a leading manufacturer of high-quality green sand iron castings, offering both gray iron casting and ductile iron casting to meet the diverse needs of various industries. Our commitment to excellence ensures you receive castings that are strong, durable, and perfectly suited for your specific application.
Gray Iron Castings
A Reliable Workhorse
Renowned for their excellent castability, machinability, and cost-effectiveness, gray iron castings are a mainstay in numerous industries. The characteristic graphite microstructure gives them a gray fractured surface and offers a well-balanced combination of strength, wear resistance, and vibration dampening.
Ductile Iron Castings
Strength Meets Versatility
Ductile iron castings are a premier choice for applications demanding exceptional strength, toughness, and flexibility. Unlike traditional cast iron, ductile iron features spherical graphite nodules that enhance its mechanical properties. This makes it a versatile material well-suited for high-durability and impact-resistant applications.
Specifications
Because versatility is important, Plymouth Foundry includes austenitic ductile iron, ductile iron, and gray iron as ASTM-grade materials in the green sand castings process.

When we receive your order, a barcoded shop card featuring digital images is created, and all pertinent details are programmed into our Manufacturing Process Control system. As your order progresses through our shop, each department has detailed instructions to ensure that your parts are made to the proper specifications.
This system documents each step in the casting process, allowing us to determine the exact cost for each part and pass the savings on to you.
Our Hartley Sand Control system enables us to regulate the characteristics of the sand used in the molding process.
We utilize advanced technologies to see that you receive what you ordered. Spectrometer analysis and automatic nodularity testing ensure conformance to your specification and traceability by part number, heat code, and ladle. Brinell testing verifies hardness per specifications.
A Melt Analysis module allows us to keep detailed records of the chemical and physical properties of the metal we pour.
Computer tracking of in-house scrap promotes pro-active continuous improvement to meet quality requirements.
A special Corrective Action module in our manufacturing software package gives us the capability of following through on problems to see that they are resolved promptly and efficiently.
Our cutting edge production scheduling program module allows us to deliver both cast and machined parts on-time.
The bar-code order tracking system we use tells us within seconds where your order is in either the casting or machining divisions. This allows us to meet promised delivery dates, and you to schedule your production runs with the assurance that your castings will arrive on time, eliminating idle machines and costly downtime.
