Huashang manufactures custom stainless steel crimp rings, support rings, lock rings and miniature assemblies for catheter-based and minimally invasive medical devices.
Each component is manufactured according to the customer’s approved drawing, material specification, dimensional tolerances and inspection requirements.
Our current manufacturing scope includes:





Huashang manufactures the metal component according to the approved drawing. Final assembly validation and functional performance requirements remain controlled by the medical-device manufacturer.

Huashang can manufacture and assemble custom lock rings and post components according to customer drawings.
Available services may include:
· Precision ring manufacturing
· Post machining
· Component cleaning
· Dimensional inspection
· Controlled assembly
· Assembly identification
· Batch-level traceability
· Final inspection reporting
All crimp rings, support rings and lock ring components are custom manufactured according to customer-approved drawings.
Common material options include:
· 316/L stainless steel
· 304 /L stainless steel
· Other materials specified by the customer
Raw-material standards are selected according to the material form and approved specification.
Examples include:Round bar/Seamless &weld Tube and Pipe /Plate& Sheet
The customer drawing and purchase order remain the controlling requirements.
Depending on the component design, our manufacturing services include:
· Precision tube cutting
· CNC machining
· Micro-ring production
· Deburring and edge finishing
· Surface polishing
· Cleaning and degreasing
· Passivation when specified
· Component assembly
· Prototype production
· Small-batch and repeat production
Machining tolerances down to 0.005 mm may be achievable for selected dimensions, subject to part geometry, material condition and inspection method.
Each production batch can be controlled through:
· Drawing and revision review
· Raw-material certificate verification
· Heat-number and material-lot traceability
· Positive Material Identification
· First Article Inspection
· In-process dimensional inspection
· Burr and surface inspection
· Final dimensional inspection
· Equipment calibration verification
· Packaging and label inspection
· QA release review
Critical dimensions can be inspected 100% when required by the approved customer specification.
