Explore our core manufacturing categories, engineered for high-precision performance across aerospace, automotive, medical, and specialized industrial sectors.
In the global manufacturing ecosystem, the demand for precision brass stamps, branding dies, and hot stamping systems has reached unprecedented heights. Unlike softer metals or cheaper alternatives, high-quality brass stamps—machined from optimal copper-zinc alloys—provide unmatched thermodynamic stability, corrosion resistance, and crisp detail transfer. They form the backbone of luxury packaging, automotive component marking, leather embossing, and high-volume industrial product labeling.
As a premier China brass stamp manufacturer & supplier, Ningbo Jiangbei XinYe Metal Works Co., Ltd. has developed comprehensive capabilities in fabricating stamping tools that withstand millions of cycles under thermal stress. Our technical expertise bridges the gap between raw metallurgy and advanced surface engineering, ensuring every custom stamp delivers micro-precision mark-making for discerning international brands.
Founded in 1996 as a family-run business, XinYe Metal has evolved into a leading owner-managed SME corporation. Nestled in the heart of the Ningbo Jiangbei Industrial Zone, our facility enjoys prime geographical connectivity, located within a 3-hour high-speed rail transit window from Shanghai International Airport.
With a comprehensive footprint encompassing 16,000 square meters of production floor and an additional 11,000 square meters of advanced construction area, we scale production seamlessly. Our multidisciplinary workforce of 130 experts comprises 80 dedicated production technicians and 50 specialists in product development, engineering, metrology, and global supply chain management.
Leveraging high-end imported tooling machinery, our manufacturing floor is optimized for multi-axis CNC milling, high-pressure hot forging, and advanced surface functionalization.
We deploy high-speed CNC turning and milling centers equipped with 4-axis control blocks. Able to hold tolerances within 0.001mm, these systems are ideally configured for deep relief engraving on complex brass stamp faces, ensuring perfect edge crispness.
Our heavy press room features friction press machines generating force limits from 300 to 1,000 tons, paired with column hydraulic presses ranging from 100 to 630 tons. This permits seamless structural stamping of thick steel, copper, and alloy backing plates.
We execute electropolishing, protective anodizing, and hard surface plating. For brass stamps, specialized passivation techniques prevent oxidation and carbon build-up during repetitive high-heat stamping operations.
| Equipment Type | Operational Capacity | Primary Application | Precision Limits |
|---|---|---|---|
| Friction Press Machines | 300 Tons - 1000 Tons | Heavy base forming and deep-drawn metal stamp structures | ±0.1mm |
| Column Hydraulic Machines | 100 Tons - 630 Tons | Precision metal forming and drawing | ±0.05mm |
| Punching Press Machines | 5 Tons - 250 Tons | High-speed stamping of brass components and blanks | ±0.02mm |
| 4-Axis CNC Machining Centers | Various Spindle Speeds | Direct complex 3D graphic engraving on brass stamp faces | ±0.001mm |
| CNC Turning & Milling Machines | Multi-axis configuration | High-fidelity contours for branding irons and metal plates | ±0.005mm |
Every stamping application presents unique thermal and mechanical variables. By matching the correct brass alloy composition (such as H59 leaded or H62 ecological lead-free brass) with application requirements, we maximize tool life and clarity.
High-end cosmetic boxes, wine labels, and book covers require flawless hot foil stamping. Our CNC-engraved brass dies retain precise heat distribution, preventing foil tearing or bleeding on textured cardstock.
For automotive leather seating, heavy wood palettes, and custom furniture branding, our brass stamps are milled with extra deep relief depth (up to 3mm) to prevent burning adjacent surfaces during hot press cycles.
From stamping logos onto confectionery products to identifying medical packaging, we utilize lead-free food-safe brass, satisfying stringent FDA compliance protocols and cleaning/sterilization metrics.
Located in the industrial hub of Ningbo, Xinye Metals leverages a robust local material ecosystem. Through our strategic network, raw brass stock is sourced directly from certified smelters with complete batch documentation, insulating our clients from supply volatility.
Our standard operations run 16 hours a day, 6 days a week. In peak demand cycles, we scale our production floor to a 24/7 continuous operation mode within 30 days. Coupled with Ningbo Port’s massive container shipping infrastructure and our 3-hour transit range from Shanghai, we guarantee predictable lead times for international orders.
Customers provide mechanical drawings, vector files, or target stamping profiles. Our engineering team reviews files for correct draft angles, relief depth, and tooling clearance.
We source the correct copper alloy grade, program our high-speed CNC workstations, and machine an initial production-grade sample. Full dimensional test reports are provided.
We present test-imprints of the sample for client validation. Any adjustments to tolerances, thermal properties, or draft angles are executed before tooling sign-off.
Upon design sign-off, we deploy bulk raw materials. High-speed CNC engraving paths generate finished stamp faces, followed by surface passivation treatments. Our quality inspectors utilize automated metrology setups to verify consistent quality across hundreds or thousands of units.
Finished products are packed in specialized heavy-duty export cases lined with moisture barriers to prevent oxidation during sea transport.
Quality is our lifeline. We maintain a strict ISO 9001-2015 certified quality management system and SA8000 social accountability standards, ensuring compliance across all workflows.
