In the modern industrial landscape, lost wax casting (investment casting) has emerged as the gold standard for producing complex, near-net-shape components. As a leading carbon steel supplier and manufacturer, JUNLONG Machinery Co., Ltd. provides the critical bridge between sophisticated engineering designs and high-performance physical components. Carbon steel, known for its exceptional strength, ductility, and cost-effectiveness, remains the most sought-after material for industries ranging from automotive to heavy construction.
Our facility in Weifang, Shandong, spanning 60,000 square meters, is more than just a factory; it is an innovation hub where advanced metallurgy meets robotic precision. With an annual capacity of 20,000 tons, we serve the most demanding global markets, ensuring that every cast component meets rigorous international standards.
The global demand for precision carbon steel castings is shifting. OEMs (Original Equipment Manufacturers) in the US, Germany, Italy, and Canada are moving away from traditional fragmented supply chains toward Full Industrial Chain Integrated Manufacturing. This shift is driven by the need for Information Gain—better data on material traceability, faster turnaround times, and reduced total cost of ownership (TCO).
Strategic procurement today focuses on:
At JUNLONG, our technical roadmap is centered on digital transformation. We have integrated Automated Precision Casting lines that minimize human error and maximize repeatability. Our roadmap includes:
1. Phase One: Simulation & Modeling - Using advanced Magma or ProCAST software to predict solidification patterns and prevent porosity before a single mold is made.
2. Phase Two: Material Engineering - Deep focus on low-alloy and carbon steel variants to improve wear resistance in agricultural and petroleum machinery.
3. Phase Three: Integrated Machining - Transitioning from "just a foundry" to a "finished part supplier" with our CNC vertical and horizontal machining centers.
Internationally advanced automated facilities significantly enhance stability and quality control.
Complete machining workshop including horizontal/vertical centers and CNC lathes for finished components.
Proven track record of exporting to USA, Germany, Italy, and Canada with full compliance support.
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. It specializes in materials such as carbon steel, alloy steel, and stainless steel. With over 200 employees, including more than 30 engineering technicians, the company is a high-quality casting supplier integrating precision casting and deep processing.
Our commitment to quality is backed by ISO 9001, TS 16949, and UL certifications. These ensure every production detail—from wax injection to final inspection—is monitored for continuous improvement.
Components for harvesters, plows, and tractors that withstand extreme soil friction and load.
Critical safety components for train braking systems and structural supports.
Forging strong mechanical backbones for excavators and cranes in harsh mining environments.
TS 16949 certified production for drivetrain and chassis precision components.
Corrosion-resistant and high-pressure-capable valves and fittings for oil and gas extraction.
Forging Strong Mechanical Backbones, Conquering Extreme Conditions
Lost wax casting provides exceptional dimensional accuracy (ISO 8062 CT4-CT6) and surface finish (Ra 3.2-6.3), reducing the need for expensive secondary machining. It allows for complex geometries that are impossible with sand casting.
Every batch of carbon steel is tested using spectral analysis. We provide material certificates (MTRs) for every shipment, documenting the chemical composition and mechanical properties like tensile strength and elongation.
Yes, with a 20,000-ton annual capacity and automated casting lines, we are designed to scale with global OEM needs, ensuring consistent lead times and quality across thousands of units.
Our products comply with ASTM, DIN, EN, and JIS standards. Our facility is certified to ISO 9001, IATF 16949 (Automotive), and UL standards.
