In the modern industrial landscape, the demand for Custom ISO certified precision casting has evolved beyond simple manufacturing. Today, leading global enterprises in automotive, aerospace, and energy sectors seek partners who provide Macro Solutions—integrating advanced metallurgy, geometric complexity, and supply chain reliability.
JUNLONG Machinery Co., Ltd., established in 2014 in Weifang, Shandong, stands at the forefront of this evolution. Spanning 60,000 square meters, we provide a vertically integrated platform for precision casting and deep processing, catering to high-load environments where failure is not an option.
Founded & Innovation Driven
Advanced Production Base
Annual Casting Capacity
We utilize internationally advanced automated casting lines that ensure consistent grain structure and dimensional repeatability. Our physical and chemical analysis labs provide real-time data on mechanical properties, meeting the stringent requirements of Carbon Steel, Alloy Steel, and Stainless Steel components.
Our footprint extends to Germany, the United States, Italy, and Canada. By adhering to international standards and leveraging strong engineering capabilities, JUNLONG has become a preferred tier-1 and tier-2 supplier for mid-to-high-end clients in Europe and North America.
Quality is engineered, not just inspected. We hold ISO 9001, IATF 16949 (TS 16949), and UL certifications. This multi-layered compliance framework ensures that every production detail—from wax injection to final machining—is traceable and optimized for high customer satisfaction.
The global precision casting market is undergoing a seismic shift toward "Lightweighting" and "Net-Zero" manufacturing. As a leading manufacturer, we are integrating Information Gain into our processes—providing clients not just parts, but data-backed metallurgical consultations. In regions like North America and Europe, our localized support ensures that technical barriers are removed, providing 24/7 engineering feedback and compliance with local environmental regulations.
Our 2030 vision includes the full integration of AI-driven thermal imaging to predict casting defects before they occur. By moving toward Industry 4.0, we aim to reduce lead times by 30% through rapid prototyping and 3D-printed sand molds for complex geometries. This technological leap ensures our partners remain competitive in a rapidly changing global market.
We are more than a foundry; we are a strategic manufacturing partner. From concept to finished product, our in-house capabilities include:
Customer Value: Single point of responsibility reduces quality risks and communication delays typical of multi-factory outsourcing.
Components for harvesters and farming equipment designed for high-stress agricultural cycles.
High-pressure valve bodies and pump accessories for oil/gas extraction and transport.
IATF 16949 compliant safety-critical parts for powertrain and chassis applications.
A: For new toolings, the sample lead time is usually 3-4 weeks. Mass production follows within 4-6 weeks depending on complexity and finishing requirements. We offer expedited services for urgent global projects.
A: We implement a 100% visual inspection combined with statistical process control (SPC). For critical parts, we utilize Non-Destructive Testing (NDT) such as X-ray, Magnetic Particle Inspection (MPI), and Ultrasonic Testing.
A: Yes. Our engineering team specializes in transitioning low-volume prototypes into scalable production models using rapid tooling techniques to minimize initial investment for our clients.
A: We cast according to ASTM (US), DIN (Germany), JIS (Japan), and GB (China) standards. Every batch comes with a material certification and chemical analysis report.
Let our engineering expertise drive your next project to success. Reliable quality, competitive pricing, and global logistics support.
