Our core competence
Here, we can provide almost all industrial metal materials and material certificates on the market. Because we are the original manufacturer, we not only provide metal casting services 【casting + machining + assembly】, but also have a complete supply chain to meet the business development needs of different customers. In addition, our outstanding level in alloy formulation and heat treatment is unsurpassed by our peers. Our process and realization capabilities for complex structural castings are also an important reason for you to choose us, which is reflected in the professional level of simulation and mold design. Of course, for custom production of casting and die-casting, more important is the ability of production traceability and quality management traceability. The production line is equipped with a customized MES system and a laser marking system, which can automatically collect die-casting machine parameters (injection speed, mold temperature), bind mold ID, and each part has an independent code, which can be traced at the VIN code level. Help customers avoid risks.
Finally, we can provide various certifications for custom castings across industries, such as automotive, aviation and medical. Because only Mulan Metal can provide you with a complete turnkey service from materials to finished products.
