We are iron foundry!
Use high quality raw materials and do continuous quality inspection.
We are a professional iron foundry with rich experience, outstanding capacity, and commitment to eco - friendly production.
Our 80,000 - square - meter factory has modern workshops and advanced equipment like furnaces and casting machines for various orders.
We offer diverse cast - iron products for construction (drainage gratings, manhole covers), machinery ( transmission wheels, engine parts), and more (water pump housing, umbrella bases). Customization is our strength for specific material, size, shape, and performance requirements.
Quality and environmental protection are top priorities. We're ISO 9001, ISO 14001, and ISO 45001 certified. We start with high - quality, eco - friendly raw materials and closely monitor production to minimize waste and emissions. Advanced inspection ensures products exceed industry standards with lowest environmental impact.
Our team provides pre - sale consultation and support, updates on order progress during sales, and offers warranties and prompt feedback after sales for long - term partnerships.

Why choose us ?
High - Quality Materials
We use top - grade cast iron materials. Our strict material selection process ensures that the impellers have excellent strength and durability, which can effectively resist wear and corrosion during long - term operation in water environments.
Advanced Casting Technology
Equipped with advanced casting equipment and techniques, we can precisely control the casting process. This enables us to produce impellers with accurate dimensions and smooth surfaces, reducing the need for excessive post - processing and ensuring the impellers' performance.
Skilled Workforce
Our workers are highly skilled and experienced in casting operations. They have in - depth knowledge of the production process of water pump impellers, from mold making to casting and quality inspection. Their expertise guarantees the high quality of each impeller produced.
Strict Quality Control
We have a comprehensive quality control system. Every water pump impeller undergoes multiple inspections during the production process, including dimensional measurement, material inspection, and performance testing. This ensures that only qualified products leave our factory.
