Your Guide to Selecting the Optimal Technology for Prototyping and Low-Volume Production
At Shenzhen EAZ Model Co., Ltd, we provide a comprehensive suite of manufacturing services to bring your ideas to life. Understanding the strengths of each technology is key to a successful project. Here’s a clear guide to three of our core processes: CNC Machining, 3D Printing (SLA), and Vacuum Casting.
1. CNC Machining: For Precision & Performance
Process: A subtractive method where a solid block of metal or plastic is carved with high-speed cutting tools to create a part.
Best For:
Functional prototypes and end-use parts that require high strength, durability, and thermal resistance.
Applications demanding extremely tight tolerances and superior surface finishes.
Parts made from engineering-grade materials (e.g., Aluminum, Stainless Steel, PEEK, ABS).
EAZ Advantage: Our multi-axis CNC workshops deliver unparalleled precision and quality, producing robust parts ready for real-world use.
2. 3D Printing (SLA): For Speed & Complexity
Process: An additive method where a laser cures liquid photopolymer resin layer-by-layer to build a part.
Best For:
Rapid prototyping for fast design verification and concept models.
Parts with complex geometries, intricate details, and organic shapes.
Low-cost iterations and visual models where material properties are less critical.
EAZ Advantage: We leverage high-resolution SLA printing to produce incredibly detailed models with smooth surfaces, drastically reducing your development time.
3. Vacuum Casting: For Affordable, Small-Batch Production
Process: A replication technique where a silicone mold is created from a master pattern (often 3D printed). Polyurethane resin is then cast under vacuum to produce multiple copies.
Best For:
Producing 10-50+ functional parts in various colors and material properties (e.g., rigid, flexible, transparent).
Bridge manufacturing before committing to expensive mass production tooling.
Parts that require consumer-grade look and feel for market testing and presentation.
EAZ Advantage: We excel at creating high-quality, cost-effective vacuum cast parts that closely mimic the final production material, perfect for pre-series launches.
How to Choose? A Simple Guide
Need 1-2 strong, precise metal parts? → Choose CNC Machining.
Need 1 fast, complex prototype? → Choose 3D Printing (SLA).
Need 20+ flexible, consumer-grade parts? → Choose Vacuum Casting.
