Engineered for excellence in the most demanding industrial environments.
Global chemical giants are shifting from "Just-in-Time" to "Just-in-Case" procurement strategies. OEM investment casting suppliers now play a critical role in providing localized support and rapid prototyping to prevent downtime in massive chemical refineries and processing plants.
The demand for Hastelloy, Monel, and Duplex Stainless Steel in investment casting has surged. Our technical roadmap focuses on achieving zero-porosity castings that can withstand sulfuric acid, chlorine, and high-temperature hydrocarbon environments.
Modern chemical industry procurement requires more than just parts. It requires factories that adhere to carbon footprint reduction goals. JUNLONG Machinery integrates energy-efficient induction melting and sand recycling to meet global ESG standards.
The chemical industry operates under some of the most punishing conditions known to man. From deep-sea oil extraction to high-pressure polymer synthesis, the integrity of a single valve or pump component can be the difference between operational excellence and environmental catastrophe. OEM Investment Casting (Lost Wax Casting) provides the unique ability to create complex internal geometries—such as turbine impellers and multi-way valve bodies—that are impossible to manufacture via traditional machining or sand casting.
In the current global industrial landscape, chemical companies are seeking Information Gain through deeper technical collaboration with their suppliers. This involves moving beyond simple blueprints to co-engineering components that optimize fluid dynamics and minimize cavitation erosion. As a leading manufacturer, we provide the technical depth required to navigate these complexities.
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.
Specializing in carbon steel, alloy steel, and stainless steel, we serve over 200 employees, including more than 30 engineering technicians. We are a high-quality casting supplier integrating precision casting and deep processing for the global chemical and petroleum sectors.

Annual Production Capacity
Utilizing MAGMASOFT® and ProCAST to simulate thermal solidification. This eliminates internal shrinkage and gas porosity in chemical pump housings before a single drop of metal is poured.
Integrating 3D-printed sand and wax patterns for rapid prototyping of complex chemical reactor components, reducing lead times from 12 weeks to 14 days.
Developing self-passivating alloy surfaces that regenerate protective oxide layers when scratched by abrasive chemical slurries.
Implementing Blockchain-based material certificates to ensure that every chemical part has a verified, immutable pedigree of its elemental composition.
Our capabilities extend beyond the chemical industry, providing high-load-bearing solutions for diverse sectors.
Forging Strong Mechanical Backbones. Excavators and cranes rely on our wear-resistant castings to operate in extreme mining and construction environments.
Custom lost wax casting for harvesters and tractors, ensuring durability during high-intensity seasonal farming cycles.
High-tech precision castings for petroleum machinery, designed to withstand the corrosive nature of crude oil and high-pressure drilling.
Marine-grade stainless steel castings that resist salt-spray corrosion for propulsion and hull systems.
Safety-critical components for braking systems and structural supports in modern high-speed railway networks.
Precision engine and brake components with strict TS 16949 compliance for global OEM automotive manufacturers.
JUNLONG Machinery is committed to the highest standards of quality management. Our certifications are not just badges; they are the foundation of our Reliability (R) in the E-E-A-T framework.
Equipped with internationally advanced automated casting production facilities.
Our workshop includes horizontal and vertical machining centers, CNC lathes, and specialized grinders. This allows us to offer Full Industrial Chain Integrated Manufacturing. We don't just provide "raw blanks"; we deliver finished, high-tolerance components ready for assembly in chemical processing lines. This reduces supply chain complexity and ensures a single point of responsibility for quality.
