Frequently Asked Questions
Continuous casting provides a much denser internal structure with fewer defects and more uniform mechanical properties, leading to better machinability and reduced waste.
For high-strength requirements, we recommend HBMCBAR500-7 (EN-GJS-500-7C) or HBMCBAR600-3 (EN-GJS-600-3C), which comply with ASTM A536 standards.
Yes, while we have standard ranges (Round: 30-650mm, Square: 30-450mm), larger diameters and custom dimensions can be produced upon request.
Hollow bars are designed to reduce material waste and machining time for cylindrical parts like bushings and hydraulic cylinders by providing an initial inner diameter.
They are widely used in automotive manufacturing, hydraulic equipment (valves/manifolds), mold making, and heavy machinery like cranes and ships.
Yes, in addition to rough-cast surfaces, we provide pre-machined and precision-ground options to meet specific project tolerance requirements.
