Custom EVA Case Manufacturer in china

Below are some of the most common questions we receive from brands, importers and e-commerce sellers considering custom EVA cases.

Q1. What is your usual MOQ for custom EVA cases? For most projects, our standard MOQ is around 500–1000 sets per SKU, but we can offer lower quantities for first orders, pilot projects or high-value applications. The exact MOQ depends on mold complexity, material combinations and how many colorways or size variations are involved.

Q2. How long does it take to develop a new EVA case from idea to mass production? A simple project can move from concept to first sample in around 7–15 days, while more complex layouts may need multiple iterations. Once the sample is approved, typical mass production lead time is 30–45 days. If you have a fixed launch date, we will work backwards to build a realistic schedule.

Q3. Do I need to provide 3D files or can you design from physical samples? We can work in both ways. If you already have 3D files or detailed drawings, we will use them directly for mold and layout development. If not, you can send us physical products and a simple sketch of how you want them arranged. Our engineering team will create the necessary CAD and structure proposals for you to review.

Q4. How do you help choose the right EVA hardness, thickness and materials? We start by understanding your product weight, fragility, user scenario and shipping conditions. Based on this, we recommend one or more combinations of EVA thickness, hardness and outer fabrics, explaining the trade-offs in cost, weight and protection. You will receive both technical reasoning and, where possible, physical samples to evaluate.

Q5. What kind of logo and branding options are available for EVA cases? We can apply your branding through several methods: rubber patches, screen or transfer printing, embroidery, metal plates or debossed/embossed panels, depending on the outer material. We will suggest options that fit your brand guidelines, desired appearance and budget, while also taking long-term durability into account.

Q6. How is quality controlled during mass production? Quality is monitored at multiple levels. We inspect incoming EVA sheets, fabrics, zippers and accessories, then perform in-process checks during cutting, molding, sewing and assembly. Before shipment, a final inspection covers appearance, dimensions, functional details, branding and packaging. Inspection standards can follow our internal criteria or be customized to your own AQL requirements.

Q7. Can you support testing and certifications for my target markets? We can help coordinate relevant tests through accredited third-party labs, such as chemical safety, environmental compliance or performance-related tests. Before that, we will review your target markets and propose appropriate test items, so that you invest in meaningful testing rather than unnecessary ones.

Q8. What information should I prepare before asking for a quotation? To give you an accurate quotation, it helps to share product dimensions, number of components, rough layout idea, target quantity, target price range, preferred fabrics or appearance references and any special standards. Reference photos or links to similar products are also very useful. With more complete information, we can quickly provide realistic options.

Q9. How do you handle design confidentiality and brand protection? We treat your designs and product information as confidential and can sign NDAs if required. We do not show your branded products or molds to other customers, and internal access to project data is limited to staff directly involved. If you prefer neutral shipping marks or unbranded packaging, we can arrange that as well.

Q10. Can you combine EVA cases with other materials or products from your group? Yes. Because we also work deeply with fabrics, webbings, bags and printing, we can design integrated solutions such as EVA cases packed inside larger bags, matching fabric accessories, or coordinated packaging sets. This is especially useful for brands that want a unified look across multiple products or categories.
