In the modern manufacturing landscape, the demand for high-integrity, complex-geometry components has elevated Precision Investment Casting (Lost Wax Casting) to a critical strategic asset. As a premier China industrial precision casting parts manufacturer, JUNLONG Machinery Co., Ltd. (founded 2014) is at the forefront of this technological shift. Our 60,000 m² facility in Weifang, Shandong, serves as a high-tech hub where metallurgical science meets automated efficiency.
The "Information Gain" in today’s casting industry lies in the transition from traditional sand casting to "Near-Net Shape" manufacturing. This process minimizes material waste and drastically reduces the need for secondary machining, offering a significant Competitive Advantage in terms of cost-efficiency and lead times. By leveraging advanced physical and chemical analysis, we ensure that every gram of carbon steel, alloy steel, or stainless steel meets the rigorous mechanical thresholds required by global industry leaders.
Integration of internationally advanced automated casting lines to eliminate human error. Stability is achieved through constant temperature wax injection and robotic shell making processes.
Utilizing CAE simulation software (like MAGMAsoft) to predict casting defects before a single mold is poured. This reduces R&D cycles and ensures first-time-right quality.
Future-proofing our supply chain through 100% wax recycling and high-efficiency induction melting, aligning with global ESG standards and carbon neutrality goals.
From high-precision truck brake lever components to lightweight rail connectors, our castings undergo 100% X-ray and ultrasonic testing. The safety-critical nature of these parts requires the IATF 16949 (formerly TS 16949) compliance we strictly maintain.
In the North Sea or the Texas oil fields, our pump and valve accessories must withstand extreme corrosion and pressure. We specialize in high-alloy steels that resist hydrogen embrittlement and thermal fatigue.
Localized support for agricultural hubs in the US and Canada. We provide custom Q345 carbon steel castings that power the next generation of autonomous harvesters and heavy-duty tillers.
