Frames jointsused in advanced electrical buses
Frames joints produced at GRINM are been used in advanced electrical buses sold in both the United States and Europe. More than five hundred clamps are used to fabricate each bus. Utilizing the semi-solid cast aluminum joints reduces the weight of the electric bus, and extends the life of the bus due to excellent mechanical properties and corrosion resistance of the aluminum castings. Joints produced at GRINM have met the customer’s specified tensile strength and elongation. More than 100,000 frame joints of three designs have been supplied.
