Case Study of Qingdao Sansen Handicraft Co., Ltd.'s PS Board Collaboration with Hisense

In recent years, the global display and smart home appliance industry has been rapidly transforming towards ultra-thin, high-definition, intelligent, and green technologies. Hisense, as a leading enterprise in China's home appliance and display fields, has seen continuous expansion in its production and sales scale. Its supply chain system urgently needs to improve its environmental protection, thinness, and high precision requirements in the field of display equipment components. PS boards (polystyrene sheets), as a core substrate widely used in display panel back panels, home appliance decorative frames, and smart terminal casings, directly determine the quality and market competitiveness of end products in terms of their environmental friendliness, molding precision, and appearance. To provide global consumers with "thinner, lighter, and more environmentally friendly" smart home appliances and display products, Hisense is actively seeking high-quality partners with mature PS board R&D, precision molding, and large-scale production capabilities.

Against this backdrop, Hisense's supply chain team visited Qingdao Sansen Handicraft Co., Ltd. for in-depth needs assessment and on-site inspection. After multiple rounds of technical discussions, both parties clarified Hisense's stringent requirements regarding PS board materials, dimensional accuracy, surface texture, and environmental indicators. Qingdao Sansen's dedicated team immediately customized an integrated solution, focusing on supplying core products such as PS backplanes for display devices, PS sheets for appliance bezels, and PS substrates for smart terminal decoration, precisely matching the design aesthetics and technical standards of Hisense's home appliances and display products.

Qingdao Sansen employs high-precision PS sheet extrusion and precision cutting processes, strictly selecting environmentally friendly PS raw materials, and using odorless, low-volatile environmentally friendly additives to ensure that products pass international environmental certifications such as RoHS, achieving core advantages such as no harmful residues, high gloss finish, and strong dimensional stability. Simultaneously, the company introduced a digital production management system to conduct full-process quality inspection of PS sheet density, thickness, and flatness. Leveraging Qingdao Port and its well-established logistics network, it ensures timely and stable delivery of large quantities of products, significantly reducing Hisense's supply chain inventory and logistics costs.

Through this collaboration, Qingdao Sansen provided Hisense with an efficient, environmentally friendly, and high-precision PS sheet supply solution, perfectly supporting the R&D and mass production of its various home appliance and display product series, helping Hisense enhance the market competitiveness of its products in terms of thinness and aesthetic appeal. With the support of Hisense's global channels and technology, Qingdao Sansen has also achieved quality upgrades and market expansion in the field of high-end home appliance components, achieving a strategic synergy that benefits both parties.
