The global precision casting industry is undergoing a paradigm shift towards "Smart Foundries." As a leading China precision casting manufacturer, we recognize that the demand for complex geometries and high-performance alloys is no longer just about cost-efficiency—it's about "Information Gain" in design and supply chain resilience. The transition from traditional sand casting to advanced investment casting (Lost Wax Casting) allows for a reduction in secondary machining, saving up to 30% in total production costs for global OEMs.
Currently, the industrial landscape in Europe and North America is increasingly relying on Chinese manufacturing hubs for high-integrity components. These hubs provide the unique combination of metallurgical expertise, rapid prototyping, and scalable production that domestic Western foundries often struggle to maintain under current energy and labor constraints.
Our role as a Global Casting Leader involves integrating advanced AI-driven thermal analysis and solidification modeling. This ensures that every part—from carbon steel truck components to stainless steel sanitary valves—is free from internal defects like porosity and shrinkage. By choosing a manufacturer with deep industrial integration, global enterprises secure their supply chain against volatility while benefiting from localized Chinese engineering speed.

JUNLONG Machinery Co., Ltd. was founded in 2014. Located in Weifang, Shandong, the 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 high-demand materials such as carbon steel, alloy steel, and stainless steel.
As a high-quality casting supplier integrating precision casting and deep processing, we employ over 200 dedicated staff, including 30+ senior engineering technicians who ensure that every blueprint is translated into a perfect physical component.
Equipped with internationally advanced automated casting production facilities, we minimize human error and maximize consistency. Our roadmap includes further integration of robotic shell-building systems.
We are expanding our alloy portfolio to include super-alloys for aerospace and high-temperature petroleum applications, focusing on enhanced corrosion resistance and tensile strength.
Utilizing high-precision physical and chemical analysis equipment to create digital signatures for every batch, ensuring 100% traceability for high-tech industry clients.
Our precision castings are not generic parts; they are engineered solutions for critical environments. Whether it's deep-sea oil extraction or high-speed rail transportation, the requirements for material fatigue and stress tolerance are extreme.
Forging strong mechanical backbones to conquer extreme conditions. From excavators to cranes, our high-strength castings support heavy-duty operations in harsh mining and road construction environments.
We provide a Full Industrial Chain capability: Mold manufacturing -> Precision Casting -> CNC Machining (Vertical & Horizontal centers) -> Surface Treatment. This eliminates quality risks from multi-factory collaboration.
In the world of industrial sourcing, "Reliability" is the most valuable currency. Our facility is certified with ISO 9001 and TS 16949, ensuring our automotive and industrial components meet the most stringent safety standards. We also maintain UL certifications for specific electrical and industrial categories.
Our process control involves spectral analysis of every melt, magnetic particle inspection (MPI) for surface integrity, and ultrasonic testing (UT) for internal soundness. This level of professional expertise is what defines a top-tier China precision casting supplier.
Investment casting, also known as lost wax casting, provides significantly better surface finish (Ra 3.2-6.3) and tighter dimensional tolerances (ISO 8062-3 CT5-CT7). This reduces or eliminates the need for expensive secondary machining, which is critical for complex parts like pump impellers or surgical tools.
Yes. While we have a 20,000-ton annual capacity, our engineering department is optimized for rapid prototyping and low-volume production for high-value industries like aerospace and specialized medical equipment.
We use vacuum induction melting and argon gas protection where necessary to prevent oxidation. Every batch is verified via spectrometer to ensure the chemical composition (Ni, Cr, Mo levels) precisely matches ASTM or DIN standards.
Typical mold development takes 2-4 weeks, depending on complexity. Once the sample is approved, mass production can be scaled within 4-6 weeks, significantly faster than many Western foundries due to our integrated mold shop.
Our company will continue to strengthen research and development efforts for new products and technologies, integrating advanced management and technical resources to become your world-class partner.
