Densen Foundry: Sand Casting Wheel Specialist And Leader in Customised Agro-machinery Parts

The sand casting process - the perfect blend of tradition and innovation

Sand casting, as a metal forming technology with a long history, is still one of the core processes in the industrial field due to its flexibility and cost-effectiveness.Densen Casting Factory is deeply committed to the sand casting field, and provides customers with high-precision and high-stability casting solutions through the scientific process control and technological innovation.

1. Core Process Steps

- Mould design and fabrication: Custom-made wooden moulds or digital models are made according to customers' needs, and the dimensions are adjusted in combination with shrinkage rate to ensure casting accuracy.  

- Moulding and core making: Use resin sand, clay and other materials to make sand model and core, and form stable cavities through vibration compaction, parting agent treatment and other techniques.  

- Melting & Pouring: Using electric furnace or cupola double melting technology, the temperature of iron is precisely controlled (1250~1350℃), and the porosity defects are reduced by the automated pouring system.  

- Cooling and Post-treatment: After cooling, the castings are subjected to sand dropping, shot blasting and heat treatment to eliminate internal stresses and improve surface quality, ensuring that the products meet industrial standards.  

2. Technological Advantages

- Complicated structure moulding: castings ranging from several hundred grams to tens of tonnes can be produced, adapting to the needs of complex internal cavities and diverse structures of agricultural machinery parts.  

- Environmental protection and high efficiency: adopting dry sand moulding and exhaust gas treatment system to reduce energy consumption and pollution, in line with the trend of green manufacturing.  

Customised agricultural machinery parts - helping to modernise agriculture

Densen Casting Plant specialises in the development and production of agricultural machinery parts, providing high-strength, wear-resistant castings to support tractors, harvesters, irrigation equipment and more.  

For many years we have been supplying agricultural machinery spare parts to customers worldwide, our customers include John Deere and Bourgault. The spare parts we offer include arms, brackets, adjusting plates, closing wheels for row sets, row cleaners and strip-till set systems (planters and seeders).

1. Core products and services

- Customised design: Customised materials, such as ductile iron and alloy steel, are made according to the operating environment of agricultural machinery (e.g. high temperature, high humidity, heavy load) to enhance the corrosion resistance and service life of the parts.  

- Diversified categories: covering key components such as gear box body, hydraulic valve body, transmission bushings, etc., supporting small-lot to large-scale production needs.  

2. Core Competitiveness of the Plant  

- Technical accumulation: more than 35 years of casting experience, mastering resin sand casting, green sand casting, lost foam castings, shell mold sand casting and other processes, and introducing professional mould manufacturing technology to shorten the development cycle.  

- Intelligent Manufacturing: Equipped with CNC machining centre to achieve intelligent control of the whole process from melting to testing.  

- Quality Assurance: ISO 9001 certified, strictly following the standard of ‘one strength, three properties’ (strength, permeability, fire resistance and yield), with a product qualification rate of over 98%.  

- Rapid Response: Support flexible procurement for global customers.  

Inquiry guidance: open up efficient cooperation.
