Since 2014 | 60,000 m² Facility
JUNLONG Machinery Co., Ltd. was founded in 2014. Located in Weifang, Shandong, the heart of China’s industrial belt, our company covers a total area of 60,000 square meters and has an annual production capacity of 20,000 tons of precision castings and machined finished parts.
We specialize in advanced investment casting (lost wax process) for materials such as carbon steel, alloy steel, and stainless steel. With over 200 dedicated employees, including more than 30 professional engineering technicians, we integrate design, casting, and deep processing into a seamless supply chain for global industry leaders.
Strategic Insights for Global Procurement Managers
Precision casting, particularly the Lost Wax Investment Casting method, has become the backbone of modern mechanical engineering. In the current global market, the demand for components that offer both high dimensional accuracy and superior surface finish has shifted the manufacturing focus toward highly automated facilities in China. As a premier manufacturer, JUNLONG Machinery bridges the gap between traditional foundry techniques and AI-driven quality control.
The China precision casting landscape has evolved from simple labor-intensive operations to high-tech manufacturing ecosystems. Purchasing departments in the US, Germany, and Japan now prioritize Chinese factories for three core reasons:
Equipped with internationally advanced automated casting facilities, we minimize human error and enhance metallurgical stability across batches.
Our facility holds ISO 9001, IATF 16949, and UL certifications, meeting the strict safety requirements of the automotive and rail sectors.
Currently serving top-tier clients in Germany, USA, Italy, Canada, and beyond, providing localized logistical and technical support.
Our engineering team works with a diverse range of alloys to meet specific mechanical properties like tensile strength, corrosion resistance, and thermal stability.
| Material Group | Common Grades | Core Benefit | Primary Applications |
|---|---|---|---|
| Stainless Steel | 304, 316, 316L, 17-4PH | Superior Corrosion Resistance | Pump Valves, Marine Hardware, Food Processing |
| Carbon Steel | WCB, LCB, 1020, 1045 | High Strength & Cost-Effective | Automotive Frames, Construction Machinery |
| Alloy Steel | 4140, 8620, Cr-Mo Alloy | Wear Resistance & Toughness | Forklift Parts, Mining Equipment, Rail Transport |
Operating as a Precision casting mechanical parts manufacturer in the global market requires more than just casting metal. It requires adherence to international legal and technical frameworks:
High-Tech precision castings for mission-critical industries.
Brake levers, chassis components, and engine brackets designed for extreme vibration and stress endurance.
Forging strong mechanical backbones for excavators and cranes operating in harsh mining environments.
Durable components for harvesters and tractors, optimized for wear resistance against soil and moisture.
The precision casting industry is undergoing a digital transformation. At JUNLONG, we are integrating several "Information Gain" strategies that set us apart from competitors:
ISO 9001 / IATF 16949 Accredited Quality Management
