05About
Silicone & plastic protective cases from Shenzhen’s electronics belt.
WJM Silicone (深圳市维嘉美橡塑电子有限公司 / Shenzhen WJM Silicone & Plastic Electronic Co., Ltd) is a protective case manufacturer based in Longgang District, Shenzhen, covering both silicone and plastic product lines. The company operates a 12,000 m² factory with over 200 employees, including a 12-person R&D team that handles everything from concept design and 3D modelling through mold fabrication and thermal simulation.
The core business is OEM/ODM protective cases for smart terminals — POS payment devices, PDA handheld computers, barcode scanners, thermal cameras, AI hardware, gaming consoles and similar electronic devices. A second business line covers automotive silicone accessories including storage boxes, cup holder inserts and interior trim parts. Roughly 80% of production is exported to the Americas and Europe.
What makes WJM particularly interesting for POS terminal buyers is the library of 80+ ready-made public molds covering major POS brands and models. These allow buyers to skip the mold development stage entirely — meaning sample turnaround as fast as 72 hours, no upfront tooling cost, and near-zero risk for standard models. For custom requirements, the factory has completed over 10,000 mold development projects to date.
The production floor runs both silicone compression molding and plastic injection molding (Haitian machines), with in-house secondary operations including surface treatment, printing, assembly and quality inspection. Materials include food-grade silicone, industrial silicone rubber, TPU, PC and ABS plastics, with the ability to combine materials for overmolded constructions.
