Design Files and Specifications Brands Need Before Starting a Custom Insulated Bottle Project

Custom insulated bottle development moves faster when the brand and manufacturer work from the same facts. At Wuyi Shuangli Cup, a 25-year manufacturer with a 100,000 square meter 5G factory, an 800 square meter R&D lab, and exports to 70+ countries, the most successful OEM projects begin with a clear design package. The company holds ISO9001, ISO14001, and FDA certifications and offers OEM customization for colors, logos, and capacity. Before a project starts, brands should prepare the following files and specifications.

1. Brand identity and logo artwork

Provide logo files in vector format whenever possible, such as AI, EPS, PDF, or SVG. If only raster artwork exists, supply a high-resolution PNG. Include brand color values, clear-space rules, minimum logo size, and preferred logo position. For the Customizable Double Wall Vacuum Thermos Bottle Personalized SUS 304 Insulated Travel Flask Light Gift Cup BPA Free Leak-Proof, OEM custom logo is available for bulk orders, so clean artwork and placement guidance are essential from the first review.

2. 3D models, 2D drawings, and reference samples

If the brand has an industrial design, share STEP, IGES, STL, or 3D PDF files plus 2D drawings with key dimensions and tolerances. Include lid, mouth, base, handle, and thread details. When CAD data is not available, clear photos, dimension sketches, and physical reference samples help define the target. Wuyi Shuangli Cup supports customizable 3D development, with 23 models available as starting points for shape and structure discussions.

3. Capacity, size, and performance specifications

Define capacity in milliliters or ounces, overall height, body diameter, mouth diameter, product weight, and any fit requirements such as cup holders or gift boxes. State whether the bottle is intended for hot or cold drinks, travel, commuting, gifting, or children. The referenced thermos bottle is a double-wall vacuum insulated travel flask with a wide mouth, leak-proof construction, BPA-free materials, thermal insulation, and washable design. These features should be confirmed against the brand's target use case in the project brief.

4. Material and compliance requirements

Specify food-contact materials for the body, lid, gasket, and any accessories. The referenced model uses SUS 304 stainless steel, a food-grade, rust-proof and durable material. Brands should also state target markets and any documentation requirements for FDA, ISO9001, or ISO14001 review. Wuyi Shuangli Cup holds ISO9001, ISO14001, and FDA certifications, which supports clear compliance planning during project review.

5. Color, finish, and decoration specifications

Supply color references such as Pantone, RAL, NCS, or physical color chips, along with gloss level and surface finish expectations. Confirm logo size, placement, and decoration method preferences. The sample product page lists white as the shown color, while OEM customization covers brand colors, logos, and capacity. Color approval should be based on a physical sample or agreed reference before mass production.

6. Packaging, labeling, and market requirements

Share retail packaging artwork, dielines, instruction manual copy, barcode and label files, and any market-specific labeling needs. Confirm shipping marks, carton requirements, and whether the bottle will be sold individually, in gift sets, or with accessories. Because Wuyi Shuangli Cup exports to 70+ countries, target market details should be included in the initial brief.

7. Commercial project brief

Include target order quantity, launch date, target price, sample approval process, and decision contacts. Clear commercial inputs help the R&D and production teams match design decisions to the brand's timeline and positioning. For OEM programs, the brand should also confirm the final capacity, logo treatment, and color direction before sampling.
