Architectural hardware is no longer just a functional necessity; it is a critical component of structural integrity, aesthetic expression, and sustainable building lifecycles. Investment casting, often referred to as "lost wax casting," represents the pinnacle of metallurgical precision, offering designers the freedom to create complex geometries that traditional machining or sand casting cannot achieve.
In the current global economic landscape, the demand for high-strength, corrosion-resistant alloys in architectural applications—such as glass spider fittings, heavy-duty door hardware, and structural connectors—has surged. As a leading China architectural hardware investment casting manufacturer, we bridge the gap between visionary design and industrial reality through advanced materials science and automated production.
Utilizing high-grade stainless steel (304/316), carbon steel, and specialized alloy steels to meet extreme environmental demands.
Achieving linear tolerances within ±0.1mm, reducing the need for expensive secondary machining and material waste.
Seamless export operations to Germany, the USA, Italy, Canada, and beyond with full compliance to international standards.
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.
We specialize in materials such as carbon steel, alloy steel, and stainless steel. With over 200 employees, including more than 30 engineering technicians, JUNLONG is a high-quality casting supplier integrating precision casting and deep processing. Our facilities are equipped with internationally advanced automated casting production lines and comprehensive physical and chemical analysis equipment.
The global precision casting market is undergoing a radical transformation. Integration of AI-driven process simulation and automated wax injection is significantly increasing "First Time Yield" rates. For architectural projects, this means shorter lead times and higher consistency in "safety-critical" hardware components.
Mega-cities in the Middle East and SE Asia are driving the need for ultra-durable architectural hardware capable of withstanding high-salinity and high-temperature environments.
Investment casting allows for "near-net shape" manufacturing, which minimizes metal scrap by up to 40% compared to traditional forging, aligning with global green building standards (LEED).
By centralizing mold making, casting, machining, and surface treatment (One-Stop-Shop), JUNLONG reduces the risk of cross-border logistics disruptions for our Western partners.
Navigating international standards is paramount. Our facility maintains ISO 9001, TS 16949, and UL certifications. This ensures that every piece of architectural hardware—whether it's a bracket for a skyscraper's curtain wall or a component for a rail transit system—meets the rigorous safety codes of North America and the European Union.
Investment casting provides superior surface finish and dimensional accuracy. For architectural hardware, this means less polishing time and a more premium aesthetic feel, which is vital for visible interior and exterior components.
Stainless Steel 316 is the industry gold standard due to its molybdenum content, which provides exceptional resistance to pitting and corrosion in coastal or high-pollution urban areas.
We offer a full-chain service. Clients provide 2D/3D drawings, our engineers perform solidification simulation to prevent defects, we manufacture the mold in-house, and then proceed to casting and precision CNC machining.
Sample development usually takes 3-4 weeks including mold creation. Mass production typically follows within 4-6 weeks depending on volume and complexity.
