Our Commitment to Quality

We understand that achieving perfection in metal casting requires a combination of cutting-edge technology and a team of skilled professionals. This is why we invest continuously in advanced facilities and equipment. Our top of the line manufacturing plant boasts a comprehensive range of modern machinery that allows us to tackle even the most complex casting projects with precision.

Our Manufacturing Capabilities

Our strategic location within China’s coal and steel energy product hub affords us a notable cost advantage, benefitting from abundant and affordable electricity supply and favorable labor costs. Annually, we manufacture in excess of 5000 tons of investment castings, as well as a quantity of sand castings.

Advanced Facilities and Equipment

Our advanced facilities and equipment include:

  • Automated Wax Injection Machines: These machines automate the process of injecting wax patterns into moulds. They can precisely control the wax pattern’s size and shape, ensuring consistency across multiple patterns.

  • Shell Building Robots: These robots automate the creation of ceramic shells around the wax patterns. They can apply multiple layers of ceramic slurry and stucco, enhancing shell quality and reducing manual labour.

  • Automated De-Waxing Equipment: Our automated de-waxing equipment are used to remove the wax from the ceramic shells. This can be done using steam, autoclaves, or other specialised equipment.

  • Robotic Pouring Systems: Our robots are used to pour the molten metal into the ceramic shells. These systems can control the pouring process with precision, ensuring consistent filling and reducing the risk of defects.

  • Automated Cleaning and Finishing Equipment: After the casting has cooled and solidified, automated equipment can be used for cleaning, cutting, grinding, and finishing processes. This machinery ensures uniformity and quality in the final product.

  • Furnace Charge: Our cutting-edge furnace charge management systems ensure precise control over the melting process, contributing to the consistency and quality of our castings.
  • High-Precision CNC Machines: Equipped with the latest CNC technology, our machines ensure the accuracy and consistency of every casting.

  • Forging Equipment: We also feature advanced forging equipment, further enhancing our capabilities and allowing us to deliver a wide range of customised metal casting solutions.

  • Coordinate Measuring Machines(CMM): We employ CMM technology for precise dimensional inspections, ensuring that every casting meets the most stringent quality standards.
