We are a professional manufacturer with over 10 years of industry experience, focusing on independent R&D, production, and after-sales service. Unlike trading companies, we have full control over product quality and delivery schedules.
For in-stock items, we can arrange shipment within 5-10 working days. For customized or out-of-stock orders, the lead time is typically 15-20 working days, which may vary slightly based on order quantity and production complexity. We will provide a detailed delivery schedule once your order is confirmed.
Yes, we offer free samples for quality evaluation. However, the courier fee is to be covered by the customer. Please note that this courier fee can be fully deducted from your subsequent official order, making it essentially cost-free for bulk purchasers.
Absolutely. Our after-sales team consists of technical experts with over 10 years of industry experience. We provide comprehensive support including product installation guidance, troubleshooting, and spare parts supply. For any issues, we guarantee a response within 24 hours and offer solutions tailored to your needs.
Our factory is located in Qingdao, Shandong Province, a major logistics hub in northern China. It takes approximately 1 hour to reach Qingdao Jiaozhou International Airport by car, and 2 hours to drive to Qingdao Port—one of the busiest container ports in the world. This strategic location ensures efficient and cost-effective shipping for global customers.
Our minimum order quantity is 1 set, which allows small businesses or trial orders to start cooperation with us. For fragile or high-value products, we recommend reinforced wooden case packaging to ensure safe transportation, with packaging costs calculated based on actual dimensions and materials used.
