Which Process’s Best for Your Plastic Parts? Injection Molding, 3D Printing or CNC?
Injection molding, 3D printing, and CNC machining are common processes for producing plastic products, and there are certain principles for selecting the right service provider for each process.
3 Key Scenarios for Choosing Injection Molding:
Mass Production Demand
When the order exceeds 500 pieces, the per-unit cost of injection molding may be only 1/10 of 3D printing, and the delivery speed improves with larger batch sizes.
Material Performance Requirements
High-temperature resistance (>120°C) or elastomeric properties (such as silicone seals)
Brand Consistency
The appearance textures (leather grain/matte) and color matching at the mass production stage can only achieve 99% consistency through injection molding molds.
| Factor | Injection Molding | 3D Printing | CNC Machining |
|---|---|---|---|
| Optimal Batch | 1,000+ pieces (steel molds) | 1-100 pieces (prototypes/small batches) | 1-500 pieces |
| Per-Unit Cost | Cheap | Medium | Expensive |
| Material Selection | 200+ engineering plastics/elastomers (ABS, PC, LSR, etc.) | Limited (mainly PLA, resin) | Limited plastics |
| Lead Time | Mold making: 7-30 days; Mass production: 1-3 days per 10,000 pieces | No mold required, 1-5 days delivery | No mold required, 3-10 days |
| Precision | ±0.1mm, VDI 3400 texture | ±0.3mm, layer marks require post-processing | ±0.05mm, mirror polishing |
| Sustainability | High (recyclable materials, waste rate <5%) | Low (resin not recyclable, support material waste 30%+) | Medium |

What measurement accuracy do you guarantee for critical dimensions?
Do you offer tooling ownership options?
Choose: Full ownership (mold storage $1 / month) or consignment model (0 storage fee, minimum order commitment).
How do you handle design changes after mold approval?
The cost of Engineering Change Orders (ECOs) depends on the content of the changes. After the mold design is completed, if the changes do not significantly affect the production and processing of mold components, we will not charge any fees. If the change order affects the processing of already machined mold bases, cavities, etc., a fee ranging from $250 to $2,000 will be charged based on the complexity. Some minor modifications can usually be completed within 72 hours.
