In the world of high-pressure fluid control, the integrity of a valve body is non-negotiable. As a leading OEM lost wax casting valve body supplier, JUNLONG Machinery employs the investment casting (lost wax) method to achieve unparalleled dimensional accuracy and surface finish. Unlike traditional sand casting, the lost wax process allows for the creation of intricate internal geometries and thin-walled structures that are essential for modern valve designs.
Our facility in Weifang, Shandong, spanning 60,000 square meters, is engineered to handle the complexities of materials such as carbon steel, alloy steel, and stainless steel. With an annual capacity of 20,000 tons, we provide information gain to our clients by not just delivering a part, but optimizing its metallurgical properties for long-term reliability in corrosive and high-temp environments.
JUNLONG Precision Facility
Integrating precision casting with deep CNC processing to ensure every valve body meets global pressure-testing standards.
Located in Weifang, the heart of China's industrial manufacturing hub, we leverage a complete ecosystem of raw material suppliers and specialized logistics. This reduces lead times and ensures price stability for our global OEM partners.
We provide extensive material certifications. Our in-house physical and chemical analysis equipment ensures every batch of stainless or alloy steel meets international ASTM, DIN, and JIS standards.
By utilizing automated shell production lines and robotic pouring systems, we eliminate human error, ensuring high consistency in valve body wall thickness and internal passage smoothness.
For international procurement departments, compliance is the highest priority. JUNLONG Machinery is not just a factory; we are a compliant partner. Our ISO 9001, TS 16949, and UL certifications are a testament to our commitment to quality management.
