Custom OEM POS Terminal Housing Precision ABS Shell & Silicone Keypad Assembly

Product Overview
This premium POS terminal enclosure is a comprehensive hardware solution featuring a high-impact ABS plastic shell integrated with a tactile silicone button plate. Engineered for durability and ergonomic performance, this assembly is designed for modern payment terminals, handheld scanners, and industrial control devices. At Shenzhen Sunmy Hardware, we provide a full-spectrum service from initial DFM (Design for Manufacturing) to final mass production, ensuring every component meets the rigorous demands of the global financial and retail sectors.

Process & Manufacturing Insights
Our production utilizes advanced Plastic Injection Molding technology to achieve the complex internal geometries required for electronic component mounting.

Precision Tooling
We utilize high-grade steel molds (NAK80 or S136) to ensure consistent dimensions over long production cycles.

Material Science
The outer shell uses premium ABS or PC-ABS blends for superior flame retardancy (UL94-V0) and impact resistance.

Secondary Processing
For the button plate, we employ Silicone Compression Molding with optional screen printing or laser etching for permanent character durability.

Integrated Assembly
Our facility supports ultrasonic welding and insert molding to ensure a seamless fit between the plastic housing and electronic interfaces.
