Steering Bracket

Product category：Attachments for construction vehicles

This steering bracket is a critical safety and load-bearing component used in the steering system of aerial work platforms. Manufactured from EN 10083-3 34CrMo4 alloy steel, it is produced using an investment shell casting process. Due to its complex geometry, concentrated loading, and safety-critical function, extremely strict casting quality is required. The complete casting must meet Level 2 X-ray inspection and Level 1 magnetic particle testing requirements, while designated critical areas require zero defects. Production therefore demands rigorous control of shrinkage, porosity, inclusions, cracks, filling, and solidification. Machining is also challenging, as multiple pin bores, mounting holes, and mating surfaces require tight dimensional, positional, and coaxial tolerances. HSKC integrates casting, heat treatment, NDT, and precision machining to ensure reliable production of safety-critical components for aerial work platforms.

Transmission Housing

Product category：Equipment and accessories

This transmission housing is designed for high-speed railway applications. Made from DIN GS-20Mn5 cast steel, the component weighs approximately 260 kg and features a large, complex geometry. It is produced using an investment shell casting process, providing improved surface quality and finer structural details compared with conventional sand casting. Its large size creates significant challenges in shell strength, metal filling, solidification shrinkage, distortion, and the prevention of porosity and shrinkage defects. Precision machining is equally demanding. Multiple flanges, bearing bores, and mounting holes are located in different orientations, requiring accurate datum establishment and carefully controlled multi-stage setups. Critical tolerances such as coaxiality, positional accuracy, and perpendicularity between machined features must be maintained throughout production. The weight of the casting and residual casting stresses can also cause deformation during machining. HSKC

Lift Arm

Product category：Attachments for construction vehicles

This lift arm is designed for Bobcat skid-steer loaders and serves as a key load-bearing component of the machine’s working system. Manufactured from ASTM A148 Grade 90-60 cast steel, the component is produced using an investment shell casting process. Its hollow structure, relatively thin overall wall thickness, and large geometry make the casting particularly challenging. Stable metal filling, uniform wall thickness, dimensional control, and internal casting quality must be carefully managed throughout production. Special attention is required to prevent incomplete filling, shrinkage, porosity, and deformation in thin-wall areas. Through optimized casting design and strict process control, the complex hollow structure can be formed as an integrated casting while balancing structural strength and weight reduction.
