Dongguan-based manufacturer provides custom phone cases, wholesale sublimation supplies and POD solutions for brands and e-commerce businesses

DONGGUAN, GUANGDONG PROVINCE, CHINA, September 8, 2026 /EINPresswire.com/ -- Dongguan Prosub Technology Co., Ltd. , a manufacturer specializing in sublimation transfer materials, equipment and blanks, is expanding its sublimation phone case manufacturing and customization services for brands, e-commerce sellers, cross-border businesses, cultural and creative studios, and print-on-demand (POD) operators.
The expansion reflects the growing demand for customized products and flexible production models. As consumers increasingly seek products that reflect individual styles, customized phone cases have become an important category for online stores, independent brands and personalized merchandise businesses. Prosub provides a manufacturing model that connects product development, mold production, blank manufacturing, coating, sublimation printing and quality inspection.

A Broad Range of Sublimation Phone Case Options
Prosub manufactures a range of phone case blanks designed for sublimation printing, including film cases, coated cases, transparent coated cases, tough film cases, tough coated cases and 2D cases. Different surface finishes, including glossy, matte, fine-pore and large-pore options, are available for different visual and printing requirements.
The company supports phone case models for major smartphone brands, including Apple, Samsung, Huawei, Xiaomi and Google. Its product development process also takes new smartphone releases into consideration, allowing compatible case models to be introduced as market demand changes.
Sublimation printing enables customized graphics to be transferred into the coating of compatible products rather than relying on surface-applied stickers. For curved phone cases, the process can also support full-wrap designs across the back and side areas, providing greater flexibility for artwork and brand graphics. Prosub’s product materials and coating options are developed with sublimation applications in mind, supporting detailed graphics and consistent surface finishes.

Integrated R&D and Manufacturing Capabilities
Product development is an important part of Prosub’s manufacturing model. The company produces blank phone cases and coating materials through its own production system and maintains capabilities covering mold development, injection molding, coating and printing processing.
This integrated structure allows Prosub to participate in different stages of a customer’s product development process. Customers can select existing phone case models for customization or work with the company on new product and mold development according to specific requirements.
The company also provides flexible production options. One-piece samples, small trial batches and large-volume production are available, allowing e-commerce sellers and emerging brands to test new designs before moving into larger production runs. This approach is particularly relevant to POD businesses, where product demand can vary according to design trends, seasonal campaigns and customer response.

Supporting Brand Customization and OEM/ODM Projects
In addition to supplying standard blanks, Prosub provides custom printing and OEM/ODM services. Depending on project requirements, customization can cover printed artwork, brand logos, product structures, materials and packaging.
These services are designed for different business scenarios, including original-design e-commerce stores, corporate merchandise programs, co-branded collections, cultural and creative products, event merchandise and cross-border e-commerce businesses. The company also provides customization for other digital accessories, including wireless earphone cases and keycaps, allowing customers to expand customized product lines beyond phone cases.
For corporate and brand projects, customized phone cases and other accessories can be developed around company logos, campaign graphics or specific visual themes. For e-commerce sellers and creative studios, the same manufacturing system can support original artwork and small-batch product testing.

Sublimation Supplies and POD Support
Prosub’s business extends beyond finished and blank phone cases. The company also supplies sublimation blanks and equipment, including sublimation transfer films and sublimation phone case machines, as well as a wider selection of sublimation blanks.
For POD operators, the combination of blanks, consumables and equipment provides a more integrated sourcing option. The company’s POD-oriented services support small sample orders, trial production and volume manufacturing, allowing businesses to evaluate market response before committing to larger quantities.
Prosub’s manufacturing and supply model is also designed to support businesses as their product lines develop. In addition to flexible order quantities, the company maintains inventories of regular blank products and provides mold development and product customization capabilities for customers requiring new models or proprietary product lines.

Quality Management and International Market Support
Quality control is integrated throughout Prosub’s manufacturing process, including material inspection, production monitoring and finished-product inspection. The company operates production bases in Dongguan and Jiujiang with a combined area of more than 33,000 square meters and holds ISO 9001 certification. Its products are supplied to customers in Europe, North America, Southeast Asia and other international markets.
Personalized products are encouraging manufacturers to move beyond standardized bulk production toward more flexible customization and on-demand models,Prosub is continuing to develop its manufacturing capabilities around this shift by connecting product development, manufacturing, brand customization, sublimation supplies and POD production within one supply chain.
