Our cast iron foundry manufactures a comprehensive range of grey iron casting grades to match your specific application requirements. We produce Class 20 grey iron for light-duty applications with good machinability, Class 30 for general engineering cast iron castings, and Class 40 for moderate stress applications.
For demanding applications requiring superior wear resistance, we offer Class 50 and Class 60 grey iron casting grades.



Our cast iron foundry offers multiple ductile iron casting grades to optimize performance for your specific application. The 60-40-18 ferritic grade provides maximum ductility and impact resistance, while 65-45-12 ferritic-pearlitic cast iron castings balance strength and ductility.
For higher strength requirements, we produce 80-55-06 pearlitic ductile iron casting and 100-70-03 high-strength iron casting grades. We also manufacture Austempered Ductile Iron (ADI) for applications demanding exceptional strength-to-weight ratio.



Our dual expertise in both ductile iron casting and grey iron casting provides clients with comprehensive material options to suit diverse application requirements. Whether your project demands the toughness of ductile iron casting or the damping properties of grey iron casting, our cast iron foundry delivers consistent quality and reliable performance.
This versatility means you can work with a single iron casting manufacturer for multiple cast iron castings needs, streamlining your supply chain and ensuring consistent quality standards across different material specifications. Our cast iron foundry team provides expert guidance on material selection based on your specific performance requirements and operating conditions.
At KT Metal Casting, every product is manufactured to order. We don't maintain inventory or produce standard catalog items. Instead, our cast iron foundry works directly with your design requirements to create custom iron casting components that perfectly match your application needs.
Our iron casting engineering team brings extensive experience in design for manufacturability, helping clients optimize their cast iron castings designs for both performance and production efficiency. We provide valuable insights on wall thickness, draft angles, parting line location, and other critical factors that influence iron casting quality and cost.
Communication is a cornerstone of our service philosophy. Unlike larger iron casting manufacturers where projects can become lost in bureaucracy, our cast iron foundry maintains direct channels between clients and our engineering and production teams. This transparency ensures that questions are answered promptly and any concerns are addressed immediately.
Our responsive approach means you'll work with knowledgeable team members who understand your custom iron casting project from start to finish. Whether you need technical guidance on grey iron casting versus ductile iron casting, production updates, or problem-solving support, our cast iron foundry staff is accessible and committed to your project's success.


All cast iron castings are carefully packaged for international shipment with custom wooden crates for heavy iron casting components, corrosion-preventive coatings for ocean freight, and shock-absorbing materials for precision grey iron casting and ductile iron casting parts. Clear labeling and documentation ensure smooth customs clearance.
We offer flexible delivery options for your custom iron casting orders. Sea freight provides cost-effective shipping for large-volume cast iron castings orders, while air freight enables expedited delivery for urgent iron casting requirements.
Rail transport offers an economical option for continental shipments, and door-to-door service provides complete logistics management from our cast iron foundry to your location.
Our cast iron foundry maintains transparent communication throughout production and shipping.
You receive real-time production updates for all custom iron casting projects, proactive notification of any schedule changes, tracking information for all cast iron castings shipments, and a dedicated logistics coordinator for complex iron casting orders.
Working with KT Metal Casting's factory has been a game-changer for our product development cycles. Their ability to accommodate design changes during the prototype phase, combined with their fast turnaround on custom castings, has accelerated our time-to-market.
The ductile iron components they manufacture for our automotive applications have passed every quality test, and their pricing remains competitive. We couldn't ask for a better foundry partner.
We switched to KT Metal Casting after quality issues with our previous supplier, and the difference has been remarkable. Their factory's quality control standards are evident in every casting we receive.
The engineering support during the design phase helped us avoid potential manufacturing issues, and their willingness to work with us on material selection saved us considerable costs. They truly understand what it means to be a manufacturing partner, not just a vendor.
For our machine tool components, we need grey iron castings with excellent damping properties and precise dimensional accuracy. KT Metal Casting has delivered on both fronts consistently.
Their foundry's green sand casting process produces superior surface finishes that reduce our post-casting machining time. After three years of partnership, they've earned our complete trust as our primary iron casting supplier.
KT Metal Casting specializes in two primary types of custom iron castings: ductile iron casting and grey iron casting. Our foundry utilizes green sand casting technology to produce both materials to exact customer specifications. As an experienced iron casting manufacturer, we can guide you in selecting the optimal material based on your application requirements, whether you need the superior strength and ductility of ductile iron or the excellent wear resistance and damping properties of grey iron.
No, KT Metal Casting operates exclusively on a custom manufacturing basis. We do not maintain any stock inventory or produce standard catalog items. Every casting produced at our foundry is manufactured specifically to your design specifications and requirements. This custom-only approach allows us to focus entirely on meeting your unique engineering needs without the constraints of standardized dimensions, and ensures that our manufacturing resources are dedicated to your active project.
Green sand casting is a versatile and cost-effective foundry process that uses a mixture of sand, clay, and water to create molds. Our factory uses this method because it offers excellent flexibility for custom manufacturing, maintains short lead times, and produces high-quality iron castings with consistent dimensional accuracy. The "green" refers to the moisture content in the sand, not the color. As a modern green sand casting foundry, we combine traditional craftsmanship with advanced equipment and quality control methods to ensure optimal results for every custom casting project.
Ductile iron casting offers superior strength, toughness, and ductility compared to grey iron, with mechanical properties that can rival steel. Our ductile iron manufacturer capabilities produce components ideal for applications subjected to shock loads, impact, or cyclic stresses. Grey iron casting, on the other hand, excels in applications requiring excellent machinability, vibration damping, wear resistance, and thermal conductivity. Our foundry team can help you determine which material best suits your specific application based on operating conditions, load requirements, and performance expectations.
Lead times for custom iron castings vary depending on project complexity, casting size, quantity, and whether new patterns need to be created. The green sand casting process used at our factory allows for relatively short production cycles compared to other casting methods. During the initial consultation, our foundry team will provide a realistic timeline based on your specific project requirements. We pride ourselves on efficient project management and maintaining clear communication throughout the manufacturing process to keep your project on schedule.
