How quickly can rapid sand-cast prototypes be delivered?
Expedited Timeline for Rapid Sand-Cast Prototypes
The delivery timeline for rapid sand-cast prototypes is significantly accelerated compared to traditional sand casting, typically ranging from 1 to 3 weeks for initial samples. The primary driver for this speed is the elimination of traditional pattern-making. By utilizing 3D Printing or CNC Machining to produce the pattern directly from a CAD model, the lead time for pattern production is reduced from several weeks to just a few days. This digital-to-physical workflow is a core component of our integrated Rapid Prototyping service.
Key Factors Influencing Lead Time
Several variables impact the exact delivery schedule:
Part Complexity & Size: Simple, smaller parts made from readily available materials like Aluminum A356 can be delivered on the shorter end of the spectrum. Larger, more complex parts with intricate cores will take longer.
Pattern Method: 3D-printed patterns are fastest for complex geometries, while CNC-machined patterns might be slightly quicker for simple, block-like shapes.
Post-Processing Requirements: If the prototype requires extensive Post Machining or surface finishing like Powder Coating, this will add to the overall lead time.
The Rapid Prototyping Workflow Breakdown
A typical accelerated timeline follows these stages: Week 1: Digital pattern creation (3D Printing/CNC) and mold preparation. Week 2: Casting, cooling, and shakeout (removing the part from the sand mold). Week 3: Basic finishing (de-gating, light Sand Blasting) and shipment. For the fastest possible turnaround, engaging our die castings Engineering team early for a design-for-manufacturability (DFM) review is highly recommended to avoid delays.
