Manufacturing of High Production Steel Shell Mold Patterns

Hitech was contracted by an Industry leader of shell molded iron compressor components, who required high speed milling of patterns to reduce draft required in casting process. The utilization of Hitech high speed milling and machining software was critical factor in the success of this project.

Our engineers developed the process and custom tooling, complete with 2D and 3D renderings and simulations. We were able to complete the machining of the tooling’s deep pockets while holding very tight tolerances of ±0.0005” with our advanced vertical milling machinery. The tooling was constructed with 4140 steel, reaching final dimensions of 45”x30”x26”.

The completed pattern featured a micro machined finish of 3.2 micron, and a 1 micron hand polished finish, this rendered secondary finishing unnecessary. Comprehensive dimensional testing and functionality testing were carried out to ensure customer specifications for quality and integrity were met. The shell mold pattern was completed within a 3 week lead time, delivered to the customer in Eastern Ohio.
