Plastic injection molding presses are classified or rated based on tonnage, or more specifically the clamping pressure or force. Presses can run in size from less than 5 tons of clamping pressure to over 4000. The higher the press ton rating, the larger the machine. Throughout the years, ACO mold has actively sought insert molding opportunities that other molders considered too high risk. Aco plastic injection molding machine rated for 68 tons can deliver 68 tons of clamping pressure. This pressure keeps the mold closed during the injection molding process. Too much or too little pressure can cause quality issues. Too much or too little pressure can also cause flashing, where excess material appears on the part edge. Pressure also impacts the viscosity of the plastic being used in the project. Melt Flow Index or MFI is a measure of the ease of flow of the melt of a thermoplastic polymer.
