VINA ITO: Japanese-standard casting and machining factory for heavy industry components

In the heavy industry, Japanese standards are not only about products achieving precise dimensions but also demand consistent stability throughout the entire production process. Especially for heavy-duty components for the heavy industry (construction machinery, mining vehicles, etc.), businesses must simultaneously meet:

-  Material stability 

-  Mechanical strength 

-  Tolerance control capability 

-  Uniformity across production batches 

-  Traceability and quality control capability 

This is also why not many businesses in Vietnam can participate in the supply chain for Japanese heavy industry manufacturers.

To meet the production standards of Japanese customers, VINA ITO has invested in an integrated system of Japanese equipment for the entire process from cast iron casting to CNC machining and quality inspection.

In the cast iron casting stage, the company uses:

-  Kitazawa medium-frequency furnace with a large capacity of 3 tons / 2,400 kW 

-  Toei Denka Kogyo Magnesium treatment equipment for FCD ductile iron 

-  Taiyo Machinery sand regeneration and processing system 

-  Yotsuden Kiko heat treatment system 

For the post-casting CNC machining stage, VINA ITO has invested in various large-scale machines from Japan, such as:

-  DMG MORI NHX8000 

-  Niigata HN100D-II 

-  OKUMA 

-  NIDEC 

-  JTEKT 

In the quality inspection stage, the company uses:

-  Hexagon 3D CMM measuring machine 

-  OBLF material composition analyzer 

-  Ultrasonic flaw detection machine 

-  Hardness and metallographic testing equipment 

These machines enable the machining and quality control of large-sized, heavy-duty components with high precision and maintain production stability for heavy industry components.

One of the key factors enabling VINA ITO to meet Japanese standards for the heavy industry is the direct inheritance of technology, production experience, and management system from its parent company in Japan – Ito Foundry Co., Ltd., a company with a history of development since 1946 in the field of cast iron casting and machining for the heavy industry. 

This is a crucial foundation that helps the company stably produce heavy-duty products ranging from 100kg to 2 tons in Vietnam, meeting stringent requirements regarding:

 Material stability

 Product deformation

 Post-CNC machining precision

 Quality consistency across production batches

Currently, VINA ITO is involved in manufacturing numerous heavy-duty ductile iron components for Komatsu's mining industry, such as the HD785-7 Mining Dump Truck, D155-6 Bulldozer, and HM300/400 Articulated Dump Truck.

Typical products include housings, carriers, front hubs, rear hubs, cases, and many other heavy-duty transmission components. These are all components with thick, heavy structures and large dimensions, and extremely high requirements for mechanical strength, load-bearing capacity, as well as quality stability during the production process according to Japanese standards.

Thanks to the integrated Japanese equipment system, invested from cast iron casting, CNC machining to quality inspection, along with the inherited experience from its Japanese parent company with a history of development since 1946, VINA ITO is currently one of the few businesses in Vietnam capable of meeting the stringent standards of the Japanese heavy industry. The capability to produce large-sized, heavy-duty ductile iron components for Komatsu's construction machinery and mining vehicles is clear evidence of VINA ITO's quality control capability, product stability, and Japanese-standard production capacity in the field of cast iron casting and heavy industrial machining.
