Founded in 2014 and headquartered in the industrial hub of Weifang, Shandong, JUNLONG Machinery Co., Ltd. has evolved from a local foundry into a globally recognized Custom Quality Assurance Supplier & Factory. Our facility spans 60,000 square meters, representing a significant capital investment in high-tech manufacturing infrastructure.
With an annual production capacity of 20,000 tons, we specialize in the "Information Gain" of material science, providing complex components in carbon steel, alloy steel, and stainless steel that meet the stringent demands of modern engineering.
In the era of "Semantic Search" and user intent, procurement officers are no longer just looking for a "supplier"—they are looking for a strategic partner who understands local regulatory landscapes and global quality standards.
Our factory is fully certified with ISO 9001 and IATF 16949 (TS 16949). For global enterprises, especially those in the US and Europe, our UL-listed processes ensure that every component enters the market with a verified safety and performance record.
We provide localized technical support by aligning our engineering documentation with international standards (ASTM, DIN, JIS). This reduces the "friction of translation" in technical specifications, allowing for seamless integration into German, American, and Italian supply chains.
Located in Shandong, we leverage the world's most complete industrial ecosystem. Our proximity to high-grade raw materials and advanced logistics hubs allows us to offer shorter lead times and superior cost-efficiency without compromising the "Quality Assurance" mandate.
We solve complex structural challenges across diverse high-tech industries.
From high-strength carbon steel truck parts to precision investment cast train components, we ensure safety in high-load transit systems.
Manufacturing Oil Cable Centralizers and durable cast steel protectors that withstand extreme pressures and corrosive environments.
Lost wax castings for farming equipment that require high toughness and wear resistance for long-term field operations.
The true Information Gain for a buyer lies in understanding how a factory controls quality at every node. JUNLONG provides a closed-loop system:
The precision casting industry is moving toward "Digital Twins" and "AI-Driven QA."
Automated wax injection and robotic shell building lines are becoming standard, ensuring consistency that traditional hand-pouring cannot match.
Real-time monitoring of melting temperatures and cooling rates allows us to predict and prevent casting defects before they occur.
Eco-friendly material recycling and energy-efficient induction furnaces are part of our commitment to global ESG (Environmental, Social, and Governance) requirements.
