Quality-oriented Development to Consolidate Overseas Export Advantages

The company has established a full-process quality traceability system with strict control over core process parameters including smelting, pouring and heat treatment. The first-pass yield of castings consistently exceeds 98.5%, and the enterprise has obtained the ISO9001 Quality Management System Certification. Over the years, we have undergone audits by leading overseas equipment manufacturers and passed on-site factory inspections by European clients on multiple occasions. Featuring high strength, high compactness and excellent corrosion resistance, our castings have long supported the supply chains of construction machinery, oil & gas exploitation and marine equipment across Europe and America, with a steady growth in the proportion of overseas orders.In terms of technological R&D, Junlong has assembled a professional casting process R&D team that carries out continuous technical breakthroughs targeting industry pain points such as shrinkage porosity in heavy-section castings, deformation of intricate thin-walled parts and cracking of alloy steel during heat treatment. We can conduct reverse structural optimization based on customers’ drawings to reduce machining allowances and cut clients’ overall procurement costs. We provide one-stop OEM & ODM customized services covering mold development, investment casting, CNC precision machining, surface treatment and export packaging.
