Math for Molders – U.S. English Imperial

Course Highlights

• Area: calculate area of various shapes (squares, rectangles, triangles, circles, and irregular shapes), and calculate total projected area at the parting line
• Ratios: calculate ratios used in screw design (compression ratio and L/D ratio) and intensification ratios for hydraulic machines
• Volume: calculate volumetric shot size and barrel capacity using a volume formula triangle
• Percent usage: calculate percent usage of barrel capacity, cushion, and maximum injection pressure
• Distance, Speed, and Time: calculate linear stroke, and calculate actual fill and speed using a distance, speed, and time formula triangle
• Averages: calculate average cavity pressure, platen deflection, and part weight
• Percent Change and Percent Variation: calculate percent change of part weights and of actual and expected fill times, and calculate percent variation of multiple parts in a multi-cavity mold
• Force, Pressure, and Area: calculate maximum available clamp force and minimum required clamp force using a force, pressure, and area triangle
