CAD Modeling & Engineering Services

Producing a successful investment casting requires more than foundry expertise — it requires close collaboration between the casting engineer and the customer's design team from the earliest stages of component development. Engineered Precision Casting Company provides in-house CAD modeling and engineering services to support customers at every stage of the casting development process, from initial concept through production release.

CAD Modeling & Tool Design

Engineered Precision Casting Company works with customer-supplied CAD data in many standard formats, including STEP, IGES, Parasolid, and SOLIDWORKS files. Often times, our engineering team can also work with our customers to generate original solid models from customer-supplied 2D drawings where digital CAD data is not available — a capability that is particularly valuable for legacy parts where original tooling and drawings may predate modern CAD systems. 

Customer CAD models are used directly in our tooling design process, serving as the geometric basis for the wax injection die design. This die model is then used to generate the CNC machining programs for the wax injection die, ensuring that the tooling accurately reproduces the intended geometry with the appropriate shrinkage allowances built in.

Metal Solidification Simulation

Before a single wax pattern is produced, our engineering team uses advanced metal solidification simulation software to predict how molten metal will flow into, fill, and solidify within the ceramic mold cavity. By importing the customer's CAD model into our simulation software and defining the casting parameters — including alloy, pouring temperature, shell preheat temperature, and gating geometry— the software generates detailed predictions of metal flow behavior, solidification sequence, temperature gradients, and the location and severity of potential defects.

Blue Light Scanning and Model-Based Dimensional Inspection

Engineered Precision Casting Company utilizes blue light scanning technology to perform rapid, comprehensive dimensional inspection of investment castings by comparing the physical casting geometry directly to the customer's CAD model. Blue light scanning captures the complete external geometry of the casting as a high-density point cloud — a three-dimensional map of the casting surface containing millions of individual measurement points — in a fraction of the time required for conventional point-by-point CMM inspection.

The captured point cloud is aligned to the nominal CAD model and a color-mapped deviation analysis is generated that visually represents the dimensional variation between the physical casting and the nominal geometry across every region of the part surface. The result is an immediately intuitive, full-surface dimensional picture that allows our engineers to assess casting conformance at a glance and identify specific regions requiring attention.
