JUNLONG Machinery Co., Ltd., established in 2014, is a premier casting supplier headquartered in Weifang, Shandong. Spanning 60,000 square meters, we maintain an annual production capacity of 20,000 tons, specializing in carbon steel, alloy steel, and stainless steel precision components.
In the contemporary energy landscape, the demand for Custom Investment Casting for the Petroleum Industry has shifted from simple component replacement to strategic metallurgical engineering. High-pressure, high-temperature (HPHT) environments in deep-water drilling and hydraulic fracturing require components with zero-defect integrity.
Supplying drill bits, mud motor components, and blowout preventer (BOP) parts that withstand extreme abrasive wear and corrosive fluids.
Precision-cast valve bodies, impeller housings, and compressor components ensuring leak-proof integrity across thousands of miles of pipeline.
Heat-resistant alloy castings for catalytic crackers and refinery units where thermal expansion management is critical for safety.
The global petroleum machinery market is undergoing a "Quality Pivot." As North American and European energy giants seek to de-risk supply chains, the focus has moved toward reliable, ISO-certified manufacturing hubs in Asia that can provide localized technical support. JUNLONG Machinery bridges this gap by offering Western-standard engineering (ISO 9001, TS 16949) with large-scale production efficiencies.
Investment casting is no longer a static technology. We are integrating Industry 4.0 principles into our Shandong facility:
ISO 9001, TS 16949, and UL certifications ensure process control over every production detail.
Equipped with internationally advanced automated casting lines for consistent mechanical properties.
From mold manufacturing to CNC machining and surface treatment, we provide a one-stop solution.
We recognize that petroleum projects operate under strict regional regulatory frameworks. Our Custom Investment Casting services include:
Adherence to American Petroleum Institute guidelines for wellhead and tree equipment.
Material cross-referencing to ensure global interchangeability of parts.
In-house X-ray, Magnetic Particle, and Ultrasonic testing for subsurface integrity.
DDP/CIF shipping options to major energy hubs in Houston, Aberdeen, and Dubai.
The company also serves as a key supplier of high-tech precision castings for industries such as automotive, rail transportation, engineering machinery, material handling machinery, agricultural machinery, and petroleum machinery.
Leveraging strong engineering capabilities, a complete quality control system, and advanced management systems, the company has become a well-known brand manufacturer in Germany, the United States, Italy, and Canada.
