Exporting to Germany, USA, Italy, Canada, and beyond. We understand the specific metallurgical requirements and import regulations of North American and European markets.
Our facility is certified under ISO 9001, TS 16949, and UL. Every batch undergoes rigorous physical and chemical analysis to ensure metallurgical integrity.
We offer specialized localization support for global clients, including localized warehouse options, DDP shipping terms, and 24/7 technical engineering consultations to bridge timezone gaps.
Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment, the company significantly enhances manufacturing efficiency and product quality stability.
From initial design to final delivery: Mold Manufacturing, Precision Casting, CNC Machining (horizontal/vertical centers), and Surface Treatment are all handled in-house to ensure traceability.
Specializing in a variety of grades, including ASTM A216 WCB, LCC, and high-alloy variations, ensuring each part meets specific mechanical property requirements.
Precision investment casting (lost wax) offers much tighter tolerances, a smoother surface finish, and the ability to cast complex internal geometries that are impossible with traditional sand casting, reducing the need for extensive secondary machining.
We utilize a full-process quality control system including Spectrometers for chemical analysis, MT/UT/PT for non-destructive testing, and CMM for dimensional accuracy, ensuring compliance with ISO 9001 and TS 16949 standards.
For new mold development, lead times typically range from 3-5 weeks for tooling and 4 weeks for initial samples. Once mass production is approved, cycles are generally 30-45 days depending on complexity.
Yes, we offer a complete range of finishes including zinc plating, nickel plating, chrome plating, powder coating, painting, and specialized anti-corrosion treatments for marine and oilfield applications.
