Product Introduction

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.
