Production site: China/DenmarkCore Strengths 1. Quality & Cost     Full Supply Chain Control: We own and operate a 100% in-house machining facility in Ningbo, collaborating only with audited, trusted suppliers for raw castings. Raw materials undergo strict pre-processing testing, and finished products are re-inspected (via Zeiss Accura 2 CMM, 100% automatic thread checkers, 100% leakage testers, and in-house material lab) before shipment-ensuring consistent European-quality output.      Lean Production: Our engineering team co-develops optimal serial production setups, aligning with automotive industry standards (TFC, APQP, PPAP) to balance high process capability and cost efficiency.  2.  Comprehensive One-Stop Solution for metal parts    Our "one-stop solution" combines six core manufacturing processes with proactive pre-project design optimization for customers,  supporting the shortening of the entire component development and production cycle.      Sand Casting: Offers both automatic casting lines (for high-volume, consistent production of ductile iron-including SiMo grades-and grey cast iron parts) and manual casting lines (for small-batch, custom-shaped components), ensuring flexibility for different order scales.       Precision Casting (Investment/Lost Wax Casting): Specializes in complex, near-net-shape parts with minimal material waste, supporting both ferritic and austenitic stainless steel grades.       Forging: Provides forged components for high-strength applications especially for stainless steel material, leveraging trusted local forging partners audited to our European quality standards.       Cold Drawing (Stainless Steel): Delivers cold-drawn stainless steel parts (e. g., fuel rail brackets) with tight dimensional tolerance and smooth surface finish, ideal for components requiring high accuracy.       CNC Machining: Our Ningbo facility houses 35 CNC 4-axis machining centers, 34 CNC turning machines-handling medium-to-high-volume machining of steel, stainless steel, and cast iron parts to meet tight precision requirements.       Powder Metallurgy: Supplies powder metallurgy components (e. g., small, complex structural parts) for weight-sensitive or high-wear applications, complementing our casting and machining capabilities. 3. Reliable Delivery      Dual-Location Support: For European customers, finished products are shipped via our Denmark warehouse (ensuring short lead times); Domestic customers benefit from direct Ningbo-based support for fast responsiveness to design changes or new requests. 4. Material Range (per DIN Standards)      We produce components for automotive and industrial sectors using: Austenitic stainless steel: 1.4301, 1.4308, 1.4401, 1.4848Ferritic stainless steel: 1.4016, 1.4509, 1.4512, 1.4526Carbon steel: S235JR, S355J2, etc. Alloy steel: 20Mn, 42CrMo, EtcIron: Grey iron, Ductile iron, SiMo grades, ADI. 5.
