Mingzhi Technology’s core making machine with a set of peripheral equipment was launched at RosALit Foundry LLC

In 2024, at the RosALit Foundry LLC in Zavolzhye city, Nizhny Novgorod Region, a MiCCAs300 core-making complex manufactured by Mingzhi Technology was put into operation for the manufacture of a set of cores for the production of a diesel 4-cylinder aluminum cylinder head using the Cold-box-amin process technology based on the MAs300 core-making machine (shotting volume 50 l, shooting plane 900×900 mm).

Mingzhi Technology successfully implemented this turnkey project, which included a comprehensive design and manufacturing solution for core tooling and the supply of a full set of process equipment for core production. In addition to the main core machine, the complex includes peripheral equipment:

• a big-bag unloading and sand feeding system,
• a centralized binder feeding and heating system,
• a centralized amine feeding system,
• a gas generator,
• a core sand mixer,
• an amine neutralization system with an automatic acid scrubber,
• a heated sand storage bin,
• a dust removal system.

The equipment’s capacity is over 20 picks up of cores per hour.

The MiCC integrated core center offers several advantages over similar systems:

• a robust design,
• a comprehensive modular system including an integrated platform above the machine housing all peripheral equipment and service platforms,
• a compact design that allows the machine to be installed in a space no higher than 8 meters.

A system for heating and maintaining optimal temperatures for binders and sand improves material savings and core quality, and also helps the machine operate in low-temperature workshop conditions.

Centralized binder and amine supply systems save personnel time on changing barrels of material by eliminating the need to move them to the machine platform. The core machine’s control system also advises when to schedule material replacement and when material is running low. Changing core tooling during setup takes no more than 8 minutes, allowing for more flexible production planning.

The advantages of the cold-box-amin process include:

• high-quality castings,
• maintaining extremely precise dimensions,
• reducing energy consumption,
• minimizing harmful emissions,
• reducing labor intensity in the finishing operations of casting production.

The new equipment has enabled the company to improve the quality of its products, reduce casting production costs, and increase productivity.
