CNC Machined & Custom Injection Molded Urethane Firearm Lens Scope Dust Covers
Using our high-speed CNC machining centers, Bermar Associates, Inc. manufactured lens scope dust covers for the firearms and sporting guns industry. These lens covers protect the gun lens from scratches, dust and debris.
The 1-cavity mold was built with a 300-grit finish and placed in our 100-ton injection molding machine for maximum efficiency. Maintaining a .005 inch or tighter tolerance, we molded the products from black, urethane material to measure precisely 4.15 inches long, 1.44 inches wide and 1.79 inches high. The finished product weighed 18 grams.
After the lens scope covers were manufactured, we shipped all units in 14 x 14 x 14 inch cartons. The 3-week turnaround period allowed the customer to receive timely shipment of the products at their Michigan facility.
The custom, injection-molded covers met ISO per print requirements and satisfied the client’s quality expectations. We produce 1,500 lens scope covers annually for this consumer.
