Injection Molded Housing for Medical Rehabilitation Equipment

Designed as an external protective enclosure for portable medical instruments or rehabilitation aids, this component is manufactured using one-piece injection molding of engineering plastics. The body features an ergonomic, streamlined contour with a large circular cutout in the center, typically adapted for sensor probes, display screens, or control knob modules. A rectangular recessed area at the front facilitates the integration of touch panels or function keys. The overall structural design balances grip comfort with secure mounting for internal electronic components.

Such irregular housings, characterized by large openings and local thin-wall transitions, impose high requirements on melt flow balance and cooling shrinkage control during injection molding. Key controls include the roundness tolerance of the circular window and the coaxiality of side-wall screw boss holes. This prevents surface sink marks, warpage, or internal stress concentration caused by wall thickness variations, ensuring flatness and locking reliability during subsequent PCB and functional module assembly.

Located in the Ninghai mold industry cluster in Zhejiang, our factory specializes in the medical rehabilitation and automotive parts sectors. We are equipped with Haitian precision injection molding machines and automated vision measuring instruments. We offer one-stop services ranging from UG/ProE structural design verification and mold flow simulation analysis to precision mold development. We customize molding parameters for engineering plastics such as ABS, PC, or PA66 to effectively solve forming challenges for complex aesthetic and structural parts, meeting the stringent delivery standards for appearance quality and dimensional stability required by medical devices.
