Custom Precision Machining in China: tolerances, lead times, and costs

When sourcing a new product, start with a small trial order — typically 10-20% of your target MOQ. This serves as a live audition for the factory. You evaluate their communication, quality, and delivery speed with limited risk. If they pass, scale up. If they struggle, you've avoided a costly mistake. This approach has saved our clients over $2M in bad inventory over 5 years.

Custom manufacturing in China follows a predictable maturity curve. First 3 months: intensive communication, samples, revisions. Months 4-12: scaling with regular quality checks. Year 2+: optimization and cost reduction. Buyers who expect perfection on the first batch are usually disappointed. Those who invest in the process during the first year consistently outperform those who jump between suppliers.
