16. Why Choose Small and Medium-Sized Factories? Differences from Large Factories.

Buyers often face a choice between large-scale manufacturers and smaller, specialized factories. Each has distinct advantages.

• Small/Medium Factories (SMEs): Offer greater flexibility for custom orders, lower minimum order quantities (MOQs often 100-500 units), faster prototyping (2-3 weeks), and more personalized service. They are ideal for startups, niche products, and aftermarket parts. However, they may lack advanced R&D and have less capacity for mass production.
• Large Factories (e.g., Brose, Denso): Provide economies of scale (MOQs of 10,000+ units), rigorous quality control, global logistics networks, and long-term reliability. They are preferred for OEM contracts and high-volume production. Disadvantages include higher minimum order requirements, longer lead times for customization, and less flexibility for small buyers.
• Recommendation: For initial market entry or low-volume orders, SMEs in China (e.g., Wenzhou Ruian, Taizhou Tenglong) are excellent. For mass production or OEM supply, partner with large global players.
