Injection-Molded Circular Components with Locating Retainer Rings and Semicircular Notched Tab

Injection-moulded locating retainer rings lose their locating function when flash at the notched tab changes the tab's effective width or when shrinkage shifts the ring's inner diameter beyond the assembly clearance tolerance; both are tooling and process control problems. Ningbo Huashun addresses this through IATF 16949-certified injection moulding with controlled mould temperature and fill parameters, producing these circular retainer rings with semicircular notched tab to your bore diameter and tab geometry tolerances. Mould tooling maintains the notch profile and tab width to your callout, ensuring consistent orientation during assembly. The production site covers just over 4,000 m². Applications cover automotive, medical equipment, and aquaculture equipments. Ningbo Huashun's experience in water meter, elevator, and pump component moulding applies directly to precision locating ring production. Supply ring diameter, tab dimensions, and required material grade with your enquiry. Huashun will confirm tooling feasibility and submit a quotation with lead time for your volume.
