The global precision casting market is undergoing a seismic shift towards "Net-Shape" manufacturing. As industries like aerospace, medical, and high-speed rail demand tighter tolerances and lower weight, Investment Casting (Lost Wax Casting) has emerged as the premier technology. By reducing secondary machining by up to 80%, it offers a sustainable and cost-effective path for complex mechanical components.
Unlike traditional sand casting, our OEM investment casting processes leverage the silica sol technique to achieve surface finishes of Ra 3.2-6.3. This "Information Gain" in production means faster assembly times for our clients and superior fatigue resistance in mechanical environments subject to high stress and vibration.
We don't just pour metal; we engineer alloys. Our in-house chemical and physical analysis laboratories ensure that every batch of carbon steel, alloy steel, or stainless steel meets ASTM, DIN, or JIS standards. This precision ensures that mechanical components in forklift parts, pumps, and valves perform reliably under extreme pressure.
JUNLONG Machinery Co., Ltd., founded in 2014 in Weifang, Shandong, represents the pinnacle of Chinese manufacturing resilience. Spanning 60,000 square meters, we have built a facility capable of producing 20,000 tons of precision castings annually.
With a workforce of over 200 dedicated professionals, including 30+ senior engineers, we integrate the entire value chain—from initial mold design and wax pattern injection to advanced CNC machining and surface treatment. Our location in Shandong, a global hub for metal casting, allows us to leverage a robust raw material supply chain and logistics network.
Strategic advantages that ensure your supply chain remains uninterrupted.
Our facility is equipped with internationally advanced automated casting lines. This automation reduces human error, ensures consistent shell thickness, and maintains a stable thermal environment for cooling, resulting in higher yield rates for complex mechanical parts.
Located in Weifang, we are strategically positioned near major ports like Qingdao. This geographical advantage reduces lead times for global exports to the USA, Germany, Italy, and Canada, ensuring your production lines never stop.
Our modern waste-management and wax reclamation systems align with global ESG standards. By choosing JUNLONG, you are partnering with a manufacturer committed to reducing the carbon footprint of industrial casting.
In the evolving automotive landscape, lightweighting is king. We provide custom castings for engine mounts, transmission housings, and suspension components. Our ability to cast thin-walled sections without compromising structural integrity is vital for the next generation of Electric Vehicles (EVs).
Precision is paramount in food processing. Our stainless steel investment castings for food machinery are corrosion-resistant and feature smooth internal passages that prevent bacterial growth, meeting the strictest FDA and international hygiene standards.
Dealing with high-pressure and abrasive environments, components like oil cable centralizers and mining drill parts require exceptional hardness. Our high-chrome alloy steel castings provide the wear resistance needed for offshore and underground operations.
Safety is non-negotiable in rail transport. We supply custom 16Mn steel precision castings for train braking systems and structural connectors, ensuring every part survives the rigorous fatigue cycles of modern high-speed rail.
The future of Precision Investment Casting is inextricably linked with digital transformation. At JUNLONG, our technical roadmap focuses on three core pillars:
As a global casting leader, our vision is to transform traditional foundries into "Smart Foundries," where data-driven decisions ensure 100% quality reliability for our European and American partners.
Our commitment to E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is backed by our rigorous quality management systems. We have obtained ISO 9001, TS 16949, and UL certifications, ensuring that every production detail is documented and traceable.
