Jiangyin Eternal Heavy Industry Co., Ltd. is a premier manufacturer specializing in high-performance custom Mold Steel Forgings. We serve demanding industrial applications with a comprehensive "ingot-to-finished-component" solution. This ensures every forged steel block meets your exact metallurgical and dimensional specifications. Our core expertise lies in producing large-scale open-die forgings and precision CNC machined blocks. Whether you need robust tool steel forgings for heavy-duty stamping or specialized blocks for plastic molding, we deliver. Our integrated manufacturing process guarantees superior structural integrity, exceptional durability, and reliable performance.
We manufacture a diverse range of mold steel forgings tailored to rigorous industry standards. Selecting the right forged steel block is critical for maximizing die life. It also reduces maintenance downtime and ensures precision in your manufacturing processes. Below is an overview of our primary categories. These options are designed to align with various operational environments and buyer requirements.
| Forging Category | Key Characteristics | Primary Applications |
|---|---|---|
| Hot-Work Mold Steel | High thermal fatigue resistance, excellent toughness, high-temperature strength | Die casting, aluminum extrusion, hot forging dies |
| Cold-Work Mold Steel | Maximum wear resistance, dimensional stability, high compressive strength | Blanking dies, punching tools, cold extrusion dies |
| Plastic Mold Steel | Superior polishability, uniform microstructure, excellent machinability | Plastic injection molds, complex mold cavities |
Our hot-work mold steel forgings are specifically engineered for high-temperature manufacturing environments. These components exhibit exceptional thermal fatigue resistance, outstanding toughness, and superior high-temperature strength. They are the ideal choice for demanding applications like die casting and aluminum extrusion. These heavy-duty hot forging dies maintain structural stability and prevent heat checking under extreme thermal cycling.
For processes operating near room temperature, we produce premium cold-work mold steel forgings. These components are designed to withstand immense mechanical stress. Our tool steel forgings are engineered for maximum wear resistance, excellent dimensional stability, and high compressive strength. They are perfectly suited for manufacturing blanking dies, punching tools, and cold extrusion dies. These applications require long-lasting durability and precision over high-volume production runs.
The plastic injection molding industry demands flawless surface finishes and intricate detailing. Our custom plastic mold steel blocks deliver excellent polishability, a highly uniform microstructure, and superior machinability. These attributes ensure that mold makers can efficiently machine complex cavities. Ultimately, this achieves the pristine surface quality required for high-end plastic components and consumer goods.
To produce world-class mold steel forgings, we rely on state-of-the-art manufacturing infrastructure. Our heavy-duty hydraulic forging presses feature capacities up to 2,000 tons. This allows us to handle massive projects with a maximum forging weight of 20 tons. Beyond large-scale open-die forging, our facility is fully equipped with advanced CNC boring, milling, and turning centers. This extensive capability enables precision machining on large-scale components up to 11,000mm in length. We ensure tight tolerances and exceptional surface finishes for every forged block delivered.
Sourcing reliable tool and die steel forgings requires a partner with proven expertise. With deep industry experience since our establishment in 2008, Jiangyin Eternal Heavy Industry stands out. We offer unparalleled quality assurance, massive production capacity, and a commitment to customer success. Our unique selling propositions are built around complete process control and uncompromising quality.
We operate a completely integrated manufacturing facility. The entire production process is handled entirely in-house. This includes raw material processing, open-die forging, precision machining, and final Non-Destructive Testing (NDT). Our "Under One Roof" approach eliminates third-party supply chain risks and reduces lead times. It also ensures complete control over production schedules and product quality.
Quality is the cornerstone of our manufacturing process. Our rigorous quality assurance protocols are backed by international certifications. These include PED 2014/68/EU Annex I Section 4.3, ISO 9001, ISO 14001, and ISO 45001. We guarantee 100% NDT and provide complete Material Test Certificate (MTC) traceability for every forged block. This gives you absolute confidence in the metallurgical integrity and safety of your components.
Every industrial application is unique, which is why we specialize in 100% custom OEM manufacturing. Backed by extensive engineering expertise, we manufacture entirely bespoke mold steel forgings. We work directly from your 2D and 3D engineering drawings. Our technical team seamlessly processes various file formats, including DWG, STEP, IGS, and PDF. We translate your exact specifications into high-performance forged components.
