Why Choose 3-Axis CNC for Plastic Parts?
3-axis CNC machining is one of the most cost-effective solutions for custom plastic parts, especially for prototypes and low-to-medium volume production.
Cost-Effective Production
Flexible & Fast Delivery
| The stable cutting process helps minimize heat buildup and deformation, delivering consistent dimensional accuracy and surface finish for engineering plastics. | No molds or tooling are required, making 3-axis CNC an economical choice for prototypes, product validation, and low-volume manufacturing. | From one-piece prototypes to repeat production, our 3-axis CNC machining supports fast turnaround, flexible scheduling, and no minimum order quantity. |
3-Axis CNC Machining Standards & Tolerance
We manufacture custom plastic parts to industrial machining standards, ensuring consistent dimensional accuracy, surface quality, and batch-to-batch repeatability for prototypes and production runs.
| Specification | Tolerances and Standard |
| Maximum Part Size | Maximum accepted part size: 48''×32'' (1200×800 mm) |
| Minimum Feature Size | Minimum accepted part size: 0.11''×0.11'' (3×3 mm) |
| Standard Dimensional Tolerance | Tolerances for plastics and composite materials are maintained at: ±0.007'' (±0.10–0.20 mm). Complies with ISO 2768/DIN 7168 |
| High-Precision Tolerance | Sindh Machining is capable of manufacturing and inspecting high-precision products according to your drawing specifications and GD&T annotations. Up to ±0.0003'' (±0.01 mm) |
| Surface Finish | The standard surface treatment is defined by the surface roughness (Ra value) following machining: Ra 0.4 μm – Ra 3.2 μm. Other surface treatment options can be specified upon inquiry. |
| Production Capability | Prototypes, Low-Volume & Medium-Volume Production |
Flatness Tolerance for Plastics | Flatness ≤0.001'' (≤0.03 mm) |
Sindh Machining manufactures standard parts according to ISO 2768-m/f and can achieve tight tolerances down to ±0.001mm (±0.0002 inches) for critical features.
Quick Selection Guide
- Choose 3-Axis CNC for most standard plastic or metal parts with simple geometries and the best cost-performance.
- Choose 4-Axis CNC when your part requires machining around a cylindrical surface or multiple indexed sides.
- Choose 5-Axis CNC for complex geometries, multi-angle features, tight tolerances, and reduced setup requirements.

FAQ |
| Can 3-axis CNC machine complex-shaped plastic parts? |
| Yes. 3-axis CNC machining is suitable for most plastic parts with flat surfaces, pockets, grooves, and multi-face features. For parts with complex undercuts, freeform surfaces, or multi-angle machining requirements, 5-axis CNC machining may be a better choice. Our engineers will recommend the most cost-effective process based on your CAD files. |
| How do you prevent plastic parts from deforming during machining? |
| We use optimized cutting parameters, low-stress machining strategies, and dedicated fixtures to minimize heat buildup and deformation. Every part is inspected to ensure dimensional accuracy and consistent quality. |
| Can you manufacture parts from a physical sample without CAD drawings? |
| Yes. We can reverse engineer your sample using 3D scanning, create CAD models, and begin production after your approval of the final drawings. |
| How much does 3-axis CNC machining cost? |
| Pricing depends on the material, part geometry, machining tolerance, surface finish, and order quantity. We provide free quotations based on your CAD files and offer competitive pricing for both prototypes and production orders. |
