About our company
Tengzhou Tiangong Machinery Co., Ltd. has been rooted in Tengzhou, Shandong – renowned as the "Capital of Small and Medium-Sized Machine Tools in China" – since 2004. As a specialized manufacturing enterprise with nearly two decades of expertise, we focus on the R&D and production of castings.
Leveraging Tengzhou's profound industrial foundation and cluster advantages in machinery manufacturing, we are committed to providing clients with high-quality castings. Equipped with mature production processes and a comprehensive quality control system, we rigorously oversee every procedure – from raw material intake to finished product delivery. This ensures our castings consistently meet clients' demanding requirements in strength, precision, wear resistance, and appearance.
Top-Tier Professionals: Expertise, Efficiency, Full-Process Guidance
Our core technical team consists of seasoned materials and metallurgical engineers with an average industry experience of over 15 years. They possess an in-depth understanding of wear-resistant and heat-resistant materials and excel in tackling demanding working conditions. From analyzing your operational environment and material selection to installation guidance and after-sales support, we provide precise technical solutions backed by profound expertise. We ensure optimal performance of liners while effectively reducing your overall operation and maintenance costs.


Exceptional Product Quality: Rigorous Process Control, Long-Lasting Reliability
We adhere to stringent standards, selecting premium raw materials and employing advanced smelting and heat treatment processes (such as vacuum melting and precise temperature control). This ensures that our wear-resistant liners (e.g., high-chromium cast iron) achieve high hardness (HRC 58–65+), robust toughness, and outstanding impact-fatigue resistance. Heat-resistant liners (e.g., high-chromium-nickel alloys) maintain superior oxidation resistance, thermal strength, and stability at high temperatures (800°C+). All products undergo rigorous testing-including metallographic analysis, hardness, impact, flaw detection, and third-party inspections-to multiply service life and guarantee long-term, stable production for your operations.
3. Tailored Product Flexibility: Precision Matching, Problem Solving
For non-standard and complex working conditions, our robust customization capability stands as a core strength. Based on your specific parameters (material type, temperature, equipment drawings, etc.), we rapidly optimize material composition, apply specialized heat treatments, and design/manufacture complex geometries. With comprehensive mold development and flexible production lines, we deliver preliminary solutions within 48 hours. Our products are engineered to perfectly align with your equipment and processes, efficiently resolving unique wear- and heat-resistance challenges to significantly enhance your productivity and economic efficiency.

Final Solution
Rapid Delivery Capability
We possess a mature production system and efficient logistics. Standard products are readily available from stock, and the production lead time for custom products is industry-leading. This minimizes your equipment downtime to the greatest extent, ensuring continuous production.
Comprehensive After-Sales Service
We provide professional installation guidance, usage and maintenance advice, and rapid on-site technical support. We also document product usage for tracking, ensuring your liners deliver optimal performance throughout their entire lifecycle and offering you worry-free operation.
Exceptional Cost-Effectiveness
Through optimized material formulations, efficient manufacturing processes, and significantly extended service life, our liners effectively reduce your per-replacement costs and overall per-ton consumption costs, delivering greater value for your investment.
