Frequently Asked Questions?

  • What can Winfung support customers to achieve their new development once we receive the design?

    We can produce different kinds of DIY waterproof bags for customers, for example: Lightweight waterproof backpack, waterproof bicycle bags, waterproof dry bag, waterproof pouch and waterproof duffel bags. Once we have customers’ design, we normally start to make a paper pattern first to evaluate the size and construction for customer’s view. It can save time and cost to help customers to review their design for shell body. In this way, our valuable customers can enjoy a review of approximate shell body without making a real sample free of charge. After further discussion, we will start a stitching sample or molding set-up to make a sample once confirmed by customers flexibly. As a professional bag factory, what I want to say is that our configuration is comprehensive, because we have our own sewing sample room and waterproof bag sample room in same building.To choose us to start your new development of waterproof bag, you will get a good and quick service.

how we work

How we process your order

Order Confirmation and Planning

Upon receiving an order, the first step is to confirm the details of the order (such as quantity, design, delivery deadline, etc.) and develop a detailed production plan based on this information. This stage is the foundation of the entire production process and needs to be accurate and error-free.

Raw Material Procurement and Preparation

Based on the production plan, procure the necessary raw materials and accessories. This stage ensures the quality of materials meets standards and that they arrive on time to avoid production delays.

Production Processing

Actual manufacturing takes place on the production line, including cutting, sewing, assembling, etc. Quality control is strict during this phase to ensure each product meets the customer's requirements.

Quality Inspection and Shipment

After production, a rigorous quality check is conducted to ensure each bag meets the set standards. Products that pass the inspection are then packed and arranged for shipment, marking the final completion of the order.
