Hengke supplies precision-cast instrument housings and covers with machined threads, openings and mounting features. Components are made to approved enclosure drawings for instrument assemblies requiring controlled mating interfaces, material traceability and application-specific inspection requirements.
Review mating joints, thread engagement, wall thickness, cable openings and mounting features against approved enclosure drawings. Explosion-protection suitability depends on the complete certified equipment design; a cast housing alone is not represented as independently certified explosion-proof equipment.
Available verification includes material documentation, dimensional reports and surface examination. Hardness checks, nondestructive testing or component-specific inspection can be agreed against the approved drawing and purchase specification.
