What is the production lead time for samples, trial orders, and full-container air cooler orders?
Production lead times for air coolers vary depending on order scale and customization requirements. Standard evaluation samples require 7 to 14 days, while trial orders of 100 to 500 units typically take 20 to 30 days. Full-container load orders (20-foot or 40-foot HQ) require 35 to 45 days for manufacturing and dispatch.
Pre-Production Sample Lead Times
Evaluation sample units require a standard preparation lead time of 7 to 14 days following technical specification confirmation and payment processing. Standard sample units are dispatched within 7 days, whereas customized OEM samples featuring specific voltage configurations, custom shell colors, or regional plug types require up to 14 days for assembly and testing.
Scalable Trial Order Manufacturing Timelines
Trial orders ranging between 100 and 500 units require a production lead time of 20 to 30 days from deposit receipt. Small-batch manufacturing runs allow suppliers to manage raw material allocation and assembly line setup efficiently while accommodating initial brand or regional control panel localizations.
Full-Container Load Mass Production Schedules
Mass production for full-container load (FCL) orders—such as 20-foot GP containers holding up to 816 units or 40-foot HQ containers holding up to 1,872 units—requires 35 to 45 days. Production schedules cover plastic component injection molding, motor copper winding assembly, evaporative pad fitting, and quality assurance testing.
Peak Season Lead Time Buffer Tolerances
Manufacturing lead times extend by an additional 10 to 15 days during peak production seasons running from January through May prior to summer demand. Importers planning bulk procurement are advised to factor seasonal buffer windows into their supply chain scheduling to prevent stockouts during peak selling months.
Production Milestones and Order Tracking
Factories monitor production through structured milestones, including raw material inspection at day 10, assembly line completion at day 25, and pre-shipment quality inspection at day 35. Buyers seeking detailed guidance on production schedules and shipping timelines can review the Expoccino Lead Time Guide page.
FAQ
How long does it take to prepare an OEM custom sample?
