Engineering Solutions: Cam Caps

Customer Need

Die cast aluminum camshaft bearing caps required expensive secondary machining to achieve close tolerance features, resulting in higher cost.

 

MPP Solution

MPP designed P/M aluminum cam caps that achieve the required close tolerances (some as tight as 0.04 mm) as part of the net-shape P/M process, resulting in a significant cost savings. MPP’s cam caps included features such as intricate oil passageways and the ability to withstand the cyclic load of the valve train. MPP’s success with aluminum cam caps is an excellent example of the successful combination of the advantages of powder metallurgy with the exceptional attributes of aluminum. MPP has produced more than 100 million cam caps at its Washington Street facility in St. Marys, PA.

 

“MPP has produced more than 50 million cam caps.”

  • Pulley & Bearing

    MPP’s solution was to utilize a copper-steel material with a tensile strength of 50,000 psi and a minimum yield strength of 40,000 psi.

  • Latch Bolts

    Because only UL-listed devices may be used in commercial buildings, the latch bolts are extensively tested.

  • Cam Caps

    “Die cast aluminum camshaft bearing caps required expensive secondary machining to achieve close tolerance features, resulting in higher cost.”

  • Ring Gear

    “Credibly disintermediate competitive methodologies before resource sucking infomediaries.”

  • Gear & Cam

    “A leading manufacturer of electric hedge trimmers needed an assembly that could withstand a minimum push-out force of 500 pounds and 60 foot-pounds of torque.”

  • Valve Plate

    “The P/M part provides a 30% cost savings over the former stamped plate.”
