Engineered for Durability, Optimized for Performance
Whitepaper: The Strategic Advantage of High-Performance Investment Casting
In the rapidly evolving landscape of global agribusiness, the demand for high-performance, durable, and precision-engineered machinery has never been greater. As a leading OEM agricultural machinery casting manufacturer, JUNLONG Machinery Co., Ltd. is at the forefront of this industrial revolution. Since our founding in 2014 in Shandong, China, we have dedicated ourselves to mastering the art and science of "Lost Wax" investment casting to serve the most demanding global markets.
Agricultural machinery operates in some of the harshest environments on Earth—encountering high friction, corrosive soil chemicals, and extreme mechanical stress. Traditional sand casting often fails to meet the tight tolerances required for modern automated farming equipment. Our investment casting process provides the "Information Gain" needed for modern OEMs: parts that require less machining, offer higher fatigue resistance, and ensure a longer lifecycle for the end-user.
Located in the heart of China's industrial hub, Weifang, our factory leverages a complete upstream and downstream ecosystem. This reduces lead times and allows for competitive pricing without compromising on material purity or engineering precision.
We adhere to strict international standards including ISO 9001 and TS 16949. For our European and North American clients, we ensure CE and REACH compliance, providing full material traceability from the raw ingot to the finished agricultural component.
Understanding that "local support" means more than just a warehouse. We offer engineering design collaboration (DFM), logistical transparency, and localized after-sales support to ensure that OEM partners in Germany, the US, and Canada have a seamless experience.
As tractors and harvesters integrate GPS and AI-driven steering, the mechanical components must be lighter and more precise. We are seeing a massive shift toward:
Where JUNLONG Castings Power the World
High-wear parts for plows and cultivators made from manganese steel for extreme abrasion resistance.
Precision gear housings and knotter frames for balers and combine harvesters where tolerance is measured in microns.
Stainless steel pump impellers and valve bodies resistant to high-pressure flow and chemical fertilizers.
Forged-strength forklift components and load-bearing brackets for heavy-duty farm logistics.
In-depth answers for procurement managers and engineers
Investment casting (Lost Wax) offers superior surface finish and dimensional accuracy. For agricultural OEMs, this means reduced machining costs, better fitment for automated components, and the ability to create complex internal geometries that sand casting simply cannot achieve.
We utilize on-site spectrometers for real-time chemical analysis during the melting process. Each batch is tested for mechanical properties, including tensile strength, yield strength, and impact toughness, ensuring compliance with international standards like ASTM, DIN, and JIS.
For new designs, mold creation typically takes 3-4 weeks. Production samples follow within 1-2 weeks. Once approved, mass production cycles generally run between 30 to 45 days, depending on order volume and secondary processing requirements like CNC machining or surface treatment.
Yes. While we have a 20,000-ton annual capacity, our flexible automated lines allow us to support mid-to-high-end clients who require specialized, low-volume components for niche agricultural applications.
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 facilities include internationally advanced automated casting production lines and comprehensive physical and chemical analysis equipment.
