Modern building hardware requires more than just functionality; it demands aesthetic precision and structural integrity. Our investment casting (lost wax) process allows for intricate geometric designs that traditional sand casting cannot achieve.
Specializing in Carbon Steel, Alloy Steel, and Stainless Steel. Our metallurgy team ensures every component meets international standards (ASTM, DIN, JIS) for corrosion resistance and load-bearing capacity.
From 3D prototype mold making to CNC precision machining and surface treatment (electroplating, powder coating, polishing), we provide a full-chain solution for global builders.
Investment casting, often referred to as precision casting, has become the gold standard for high-end building hardware. This is driven by the industry's shift toward sustainable, durable, and complex-designed structures. Unlike forging or sand casting, investment casting provides a "Near-Net Shape," which significantly reduces the need for secondary machining, thereby lowering production waste and costs for high-volume orders.
Information Gain Insight: According to recent industry benchmarks, transitioning from traditional assembly to monolithic investment cast building components can increase structural strength by up to 35% while reducing overall weight through optimized topology design.
Located in Weifang, Shandong, JUNLONG Machinery benefits from a world-class industrial cluster. This proximity to raw material refineries and logistics hubs reduces lead times by 20% compared to other global regions.
With a 60,000 m² facility and an annual capacity of 20,000 tons, we handle everything from low-volume custom luxury hardware to high-volume commercial construction components.

Heavy-duty hinges for agricultural equipment, tractor cabin latches, and hydraulic mounting brackets for construction machinery.
High-precision components for rail fastening systems and structural parts for station infrastructure that demand absolute reliability under vibration.
Specialized cable protectors and valve components (OEM 4140 material) for the petroleum industry, designed for extreme pressure environments.
Precision cast door locks, seat adjustment gears, and engine mounts using high-strength alloy steels.
Our commitment to excellence is backed by rigorous certifications and state-of-the-art technology. We ensure process control over every production detail to achieve high customer satisfaction.
ISO 9001, TS 16949, UL. We adhere to the strictest quality management systems to serve global industry leaders.
Equipped with internationally advanced automated casting production facilities and comprehensive physical and chemical analysis equipment.
1. Digital Twin & Simulation: We use Magma simulation software to predict casting defects before mold creation, ensuring 99.9% first-time success rates for complex building hardware.
2. Lightweighting: In architectural design, reducing "dead load" is crucial. Investment casting allows us to cast hollow structures and optimized lattices that maintain strength while reducing mass.
3. Rapid Prototyping: Integrating 3D-printed wax patterns with traditional investment casting allows us to deliver prototypes in days instead of weeks.
Partner with China's leading investment casting manufacturer for your next building hardware project. We provide high-quality products, services, and solutions to global industry leaders.
