The moment final design approval is granted marks a critical pivot from concept to reality. However, the start of mass production on the factory floor isn't instantaneous. The timeline that follows is a meticulously orchestrated phase of transformation. Typically, this period can range from a few weeks for simple products to several months for complex items.

The journey begins immediately after the approved design files are released to the manufacturing team. The first major stage involves Engineering for Manufacturing (DFM) and finalizing all technical specifications with the factory engineers. Concurrently, the process of tooling and mold creation commences. This is often the longest lead-time item, especially for plastic injection molds or custom dies, which can take 4 to 12 weeks or more.

Simultaneously, the procurement of long-lead materials and components kicks off. Sourcing specialized electronics, custom fabrics, or regulated raw materials must align with the production schedule. Once tooling is ready, the First Article Inspection (FAI) or prototype run occurs. This sample is rigorously tested against all specs, and any required adjustments cause a feedback loop to tooling.

Following sample approval, the factory enters the pre-production run phase. A small batch is manufactured using the full production line to validate processes, worker training, and quality control checks. Only after this run is successfully signed off does the official mass production start commence.

Key factors influencing this timeline include product complexity, factory capacity, seasonal demand peaks, and the efficiency of communication. Clear documentation, responsive feedback loops, and established supplier relationships are crucial for minimizing delays. While a general benchmark is 8 to 16 weeks, a detailed project plan with your manufacturing partner is essential for setting accurate expectations for your specific product.
