Several improvements were made, including tightening up the tolerances on the bores to prevent material stagnation and increase throughputs. Diamond America neutral thrust feeders were added to encourage material movement to the center of the hopper allowing positive feed while also decreasing wear on bearing components. We also added our two-piece shaft system between the hopper and the gearbox to promote ease of disassembly and maintenance. The OEM gearbox was redesigned by replacing bronze bushings with needle bushings that will increase efficiency and longevity of the motor.
Beyond extrusion we offer rebuild of wear parts in the granulating/compaction/pelletizing industries. Our experience in metallurgy, combined with our extensive manufacturing capability, allows us to produce components of superior quality and increased durability. In addition, Diamond America offers rebuild services for sheet, cast film, blown film, laminating and coating dies as well as screws and barrels of all makes.
