Dongying Hengke Precision Casting Co., Ltd., a leading manufacturer in China’s foundry industry, has pioneered advancements in casting technology by integrating fiber reinforcement into its production processes. Specializing in high-precision castings, the company serves sectors such as aerospace, automotive, energy, and industrial machinery, delivering components renowned for their dimensional accuracy, surface quality, and mechanical performance.
Hengke’s core expertise lies in producing castings from diverse materials, including stainless steel, alloy steel, carbon steel, and aluminum alloys. These materials are selected to meet stringent requirements for corrosion resistance, strength, and lightweight properties, catering to applications ranging from turbine blades and hydraulic valves to automotive engine parts and medical equipment components. By leveraging advanced investment casting techniques, the company achieves tolerances as tight as ±0.1 mm and surface finishes below Ra 3.2 μm, ensuring compatibility with complex designs and critical functional demands.
To address challenges like thermal stress cracking and dimensional instability during casting, Hengke has introduced fiber-reinforced silica sol shell technology. By embedding ceramic fibers (e.g., alumina-silica) into the silica sol binder, the company enhances the shell’s thermal shock resistance and tensile strength. This innovation reduces shell cracking rates by 40% during high-temperature dewaxing and pouring, while improving casting yield by 15%. The fibers also enable thinner shell layers, accelerating drying times by 30% and lowering energy consumption.
Beyond material benefits, the fiber-reinforced shells support sustainable production. Reduced shell waste and shorter cycle times align with Hengke’s commitment to eco-efficient manufacturing. Clients report fewer defects in castings, such as shrinkage porosity and surface irregularities, leading to cost savings in post-processing.
“Fiber technology is a game-changer for complex geometries,” notes Mr. Li, Hengke’s R&D Director. “It allows us to push the boundaries of what’s possible with traditional investment casting.” The company continues to refine the technology, exploring hybrid fiber blends and automated shell-building systems to further optimize quality and productivity.
With a focus on innovation and customer-centric solutions, Dongying Hengke remains at the forefront of precision casting, empowering industries with components that balance performance, reliability, and sustainability.
