In the modern industrial landscape, "Precision" is not just a measurement—it is a competitive mandate. Custom precision casting, specifically lost wax investment casting, has evolved into a cornerstone technology for aerospace, automotive, medical, and energy sectors. As a leading precision casting service supplier, JUNLONG Machinery Co., Ltd. provides the critical "Information Gain" required for procurement officers and engineers to transition from traditional manufacturing to high-efficiency, net-shape production.
Equipped with internationally advanced automated casting facilities, significantly enhancing manufacturing efficiency and product quality stability while meeting comprehensive testing requirements.
Specializing in carbon steel, alloy steel, and stainless steel. Every batch undergoes rigorous physical and chemical analysis to ensure mechanical property compliance.
Proudly exporting to Germany, the United States, Italy, and Canada, serving high-tech industries with localized support and global compliance standards.
Founded in 2014 and located in Weifang, Shandong—the heart of China's industrial casting cluster—JUNLONG Machinery Co., Ltd. covers a total area of 60,000 square meters. We are a high-quality casting supplier integrating precision casting and deep processing (CNC machining).
With over 200 dedicated employees, including 30+ senior engineering technicians, we bridge the gap between design concepts and industrial-grade finished parts.
Procuring from a China investment casting supplier offers more than just cost savings. It provides access to a vertically integrated ecosystem. In Shandong, the proximity to raw material refineries and specialized surface treatment facilities allows us to reduce lead times by 30% compared to fragmented western supply chains.
We adhere to ISO 9001, TS 16949, and UL certifications. For our clients in North America and Europe, we provide full traceability reports and material certifications (3.1/3.2) to meet local regulatory mandates.
Our proximity to major ports like Qingdao ensures seamless maritime logistics. We support DDP, CIF, and FOB terms, providing localized warehousing solutions through partners in the US and Germany.
Our 30-strong engineering team works in your timezone to offer Design for Manufacturing (DFM) advice, optimizing part geometry to reduce weight without sacrificing strength.
Our precision casting services are tailored for environments where failure is not an option. By utilizing lost wax technology, we achieve tolerances of +/-0.125mm per 25mm, perfect for:
Custom lost wax casting for harvesters and farm vehicles, focusing on wear resistance and toughness under high-load soil conditions.
TS 16949 compliant components for truck brake levers, forklift components, and railway parts. High-strength alloy steel ensures passenger safety.
Forging strong mechanical backbones for excavators and cranes. We specialize in complex structural parts that withstand extreme mining environments.
The precision casting service industry is undergoing a digital transformation. At JUNLONG, we are integrating AI-driven simulation software to predict thermal stress and solidification patterns before a single mold is made. This reduces waste and ensures the first-article inspection (FAI) success rate is near 100%.
Current trends include the move towards Stainless Steel 316L and Duplex alloys for offshore and hydrogen energy applications, where corrosion resistance is paramount. Our factory is already optimized for these advanced materials.
Our commitment to quality is backed by a full-process control system. We don't just cast; we validate.
Usually, mold development takes 2-3 weeks, followed by sample production (1 week). Mass production typically ranges from 4-6 weeks depending on the order volume and complexity.
We recommend Alloy Steel (such as 4140) for high strength and toughness, or Stainless Steel (304/316) for parts requiring corrosion resistance. Carbon steel is the most cost-effective for general structural use.
Yes, we are a one-stop supplier. Our workshop includes vertical and horizontal machining centers, ensuring your parts are delivered "ready to assemble" with precise tolerances.
Every heat is tested using spectrometers. We provide chemical composition reports and mechanical property test results (tensile strength, yield, elongation) with every shipment.
