Female Insert Plug for the Freight Transportation Industry

Working with a freight transportation client located in Boston, MA, Rochester Technology and Manufacturing - RTMA produces a female insert plug used in a truck-to-trailer attachment application. The production process involves our multi slide stamping services, as well as assembly and packaging steps for final delivery of the completed part. Our multi slide stamping press produces the body of the insert plug from .025" thick CDA 260 brass, stamping each piece measuring 1.810" long, .314" tall, and with a width between .325" and .340", maintaining a ±.005" tolerance. In addition, a #6-40 thread is formed at one end of the piece, for insertion of a UNF-2A machine screw with a .250" thread length.

Our multi slide stamping press operates at 40 strokes per minute, stamping 1 piece per stroke for 2,550 parts per hour. For the assembly/screw insertion step, our customer requires that the screw is assembled all the way down into the piece, with no cross threading, and torque not to exceed 4 lbs.-in. This produces a final, assembled product weighing .014 lbs., with a yield stress @2% between 72 and 77 KSI, a #3 edge type, and the ability for the thread to withstand a minimum 8.0 lbs. of torque.

To complete our client's order, we package 8" x 8" x 8" white CAR boxes, 2,000 parts per box, onto 2 and 3 layer skids with 20 boxes per layer. This customer's annual order is 100,000 insert plugs, with a standard production time of 5-6 weeks and delivery within 8-10 weeks.
