Chifine
Precision-crafted to meet the highest industrial standards, our Investment Casting Cast Steel Machined Components are engineered for railway train spare parts and other heavy-duty industrial applications. At Chifine, we use silica sol precision casting, also known as lost-wax investment casting, to ensure outstanding dimensional accuracy, superior surface finish, and consistent mechanical performance. This advanced method is especially suitable for manufacturing complex geometries and high-precision components, making it ideal for the evolving demands of the automotive, engineering, and railway industries.
We adopt the silica sol investment casting method, known for its exceptional accuracy and ability to produce parts with intricate detail. This process allows for tight tolerances and excellent repeatability, making it the preferred choice for cast steel railway components and other high-performance parts. It is particularly effective for parts with minimum wall thicknesses of 2mm and unit weights ranging from 0.01 kg to 100 kg. The lost-wax casting process not only supports mass production but also significantly reduces the need for extensive post-casting machining.
The resulting castings offer fine surface finish and minimal porosity, ensuring they meet both DIN and ASTM quality standards. Each part is produced with careful attention to design accuracy, ensuring that even the most demanding applications—such as high-vibration railway environments—are supported by structurally sound components.
Chifine's precision-cast parts are available in a variety of high-strength materials tailored to your application needs. These include carbon steel, alloy steel, and stainless steel, with full traceability and compliance to internationally recognized standards.
Available carbon steels include:
AISI 1020, AISI 1035, AISI 1045
GrD (Q235), Gr50 (Q345)
Alloy steels offered:
AISI 1053, AISI 4137, AISI 4140, AISI 4340, 20CrMo, 20CrMnMo, A387Cr.12
Stainless steels include:
ASTM 304, ASTM 304L, ASTM 316, ASTM 316L
Depending on the application, we provide custom heat treatment options such as normalizing, tempering, and hardening & tempering, optimizing the mechanical properties like tensile strength, ductility, and wear resistance. This is particularly essential in railway train spare parts where durability under dynamic load is crucial.
Our casting capabilities extend beyond molding. We provide a wide array of post-processing surface treatments to enhance corrosion resistance and aesthetic appeal. Options include:
Shot blasting for uniform surface texturing
Chromate plating for enhanced corrosion resistance
Powder coating and anodizing for application-specific protection and visual consistency
We also offer OEM and ODM services, allowing you to customize everything from part geometry to finishing details. Our team ensures each casting aligns with your precise design requirements, backed by our ISO9001:2015-certified manufacturing process for full quality assurance.
Our commitment to quality is demonstrated through rigorous quality control and full documentation. Each batch undergoes detailed inspection, including dimensional analysis and metallurgical testing. Moreover, our machining capabilities ensure that even after casting, parts are fine-tuned to meet your tolerance specifications, providing a ready-to-install solution with minimal secondary processing.
By combining lost-wax casting technology with high-grade materials and expert engineering, Chifine delivers products that meet the latest industry trends—including lightweight design, modular compatibility, and enhanced fatigue life—ensuring you stay competitive in a rapidly evolving marketplace.
At Chifine, we’re more than just a foundry—we’re your partner in advanced metal solutions. With decades of experience in investment casting and machined railway components, we are ready to meet your needs for precision, reliability, and custom engineering.
