Manufacturing Cost Reduction Strategies for China Production

Reducing manufacturing costs is a continuous process. This guide covers proven strategies for optimizing costs without sacrificing quality when manufacturing in China.

1. Design for Manufacturing (DFM)

• Reduce wall thickness variation
• Minimize tight tolerances — only apply where functional
• Reduce number of components (consolidate parts)
• Simplify assembly: snap-fits vs. screws
• Avoid deep ribs, sharp corners, undercuts

2. Material Optimization

• Specify standard stock sizes (avoid custom extrusions)
• Use commodity materials where possible
• Consider material substitution (e.g., ABS vs. PC/ABS)
• Negotiate annual volume pricing with material suppliers
• Minimize scrap: nesting optimization for sheet metal/wood

3. Process Efficiency

• Increase cavity count (molds: 4 instead of 2 cavities = 40-50% lower per-part)
• Reduce cycle time through cooling optimization (Mold Flow)
• Automate secondary operations (degating, assembly)
• Implement statistical process control to reduce scrap

4. Volume Consolidation

• Combine multiple SKUs into single production runs
• Negotiate annual contracts (5-15% discount over per-order)
• Consolidate suppliers: fewer suppliers = stronger leverage

5. Logistics Savings

• Use sea freight vs. air (save 70-80%)
• Consolidate LCL into full containers where possible
• Optimize packaging density (smaller boxes = lower freight)

Typical Savings Potential

DFM alone: 10-30%. Material optimization: 5-20%. Process efficiency: 10-25%. Volume consolidation: 15-40%. Combined approach: 25-50% total cost reduction possible with systematic effort.
