Basics of The Plastic Injection Molding
While plastic injection mould and Press mold maker can assist you in determining the size of the machine required to get the best results, a project designer or engineer can provide an accurate estimate based on some basic information. Knowing the approximate size of the machine required allows you to better locate a plastic injection moulded that will fulfil your demands. Plastic injection moulding presses are classed or graded according to tonnage, or more precisely, clamping pressure or force. Presses range in size from less than 5 tonnes of clamping pressure to more than 4000. A machine rated for 68 tonnes can produce 68 tonnes of clamping pressure. This pressure maintains the mould closed throughout the injection process. Too much or too little pressure might result in quality concerns. Too much or too little pressure can also result in flashing, which is when extra material forms on the component edge. Pressure also affects the viscosity of the plastic utilised i...
