Product Introduction

The Best Choice for Large and Complex Parts

Sand Casting Automotive Parts are made with resin sand casting. This method gives better surface finish and accuracy than traditional clay sand casting. Our product include engine blocks, cylinder heads, and large housings. These parts have complex internal water and oil passages. Sand casting is the only practical way to make them. Die casting cannot handle these internal features. We use A356.2 aluminum alloy for our sand castings. After T6 heat treatment, tensile strength exceeds 310 MPa. That is significantly higher than many conventional gravity castings.

Engineering Precision for Small Batches

We once worked with an off-road vehicle company. They needed reinforced cylinder heads. The design was complex. The volume was small. Several foundries refused the job. We accepted it. From mold design to first article delivery, we finished in six weeks. Our Sand Casting Automotive Parts passed all bench tests. The customer later gave us three more models. Good sand casting is not a matter of luck. It is a matter of good design. We design the gating system. We place the risers correctly. We control the solidification sequence. Every step is backed by data and simulation.

Full-Service Support Under One Roof

We offer strong engineering support for your Sand Casting Automotive Parts. This includes mold design, casting simulation, pouring control, T6 heat treatment, X-ray inspection, and precision CNC machining. All of this happens in our factory. Our IATF 16949 certification shows our commitment to quality. We also perform metallographic inspection and 100% leak testing on critical parts. Good sand castings can be as good as die castings. In some cases, they are even better. They offer superior internal quality and mechanical properties. When you need large, complex parts in smaller volumes, our sand casting service is the right solution.
