Precision CNC Machining of an Aluminum Vial for the Pharmaceutical Industry

Allied Precision was contracted by a customer in the pharmaceutical industry for the custom machining of a "monoblock" vial, used for medical pill dispensing. Precision CNC turning and milling processes were carried out on 6061 T6 aluminum, using our advanced CNC mill. Boring operations were also applied for the inside diameter. Finished dimensions for the part were 0.75" high, an outer diameter of 7.100", and an inner diameter of 1.520", with a weight of 1.74lbs. Tightest tolerances of +0.005" and: ± 1° (angular) were held throughout production.

The unit was cleaned and prepared for further treatment with our deburring process, and ultimately treated for abrasion resistance and corrosion protection with a type II class II clear anodizing treatment, carried out per MIL-A-8625. 500 units were packaged and shipped to the customer on the East Coast. Typical lead time for a project of this magnitude is 4 - 6 weeks. At Allied Precision we specialize in high quality CNC machining, manufacturing to the exacting standards of our industrial clients.
