Customization and Quality Commitment
We offer full-size customization with adjustable outer diameter, inner diameter, thickness, and tolerance ranges to meet your specific requirements. All products come with complete Material Test Reports (MTR), grain size inspection reports, and heat treatment records, and support aerospace certifications such as AMS and NADCAP, ensuring every forged rolled ring meets stringent industrial standards.
DINGSCO Complete Production Chain:
SMELTING → FORGING → HEAT TREATMENT → MACHINING → HOT EXTRUSION
①Foundational Assurance in Smelting and Forging:
VIM furnaces ensure alloy purity; ESR furnaces further optimize internal structure. Forging yields diverse billets, laying a defect-free foundation for downstream processing and controlling material properties at the source.
②Precision Control in Intermediate Processing:
Heat treatment is customized for alloys. CNC machining enables high-precision forming, yielding semi-finished parts to ensure pre-extrusion billets meet forming specs.
③Synergistic Value of Hot Extrusion with Full Process:
The new hot extrusion press is part of an integrated system: High-purity alloys (VIM/ESR), dense forging microstructures, and heat-treated performance collectively enable stable extrusion of hard-to-form alloys. Produced complex components: seamless pipes, profiles; material utilization up 15-20%. Full-process efficiency cuts standard model lead times to 5-10 days.
④Quality and Delivery Assurance:
Every batch comes with EN 10204 Type 3.1 certification, inspected by our internal QC team. We support third-party audits (BV, SGS, etc.), and offer custom manufacturing per drawings with sample testing available.
