Injection moulding machine, injection unit, mould closing unit and adjusting method

The invention relates to an injection moulding machine, an injection unit or a mould closing unit thereof and a method for adjusting an injection process or a pressing process. In a first step, the adjustment of a force curve, a speed curve and/or a power curve for a drive device during the injection process or the pressing process is selected. In a second step, at least one injection process or pressing process is performed and an actually required injection force or pressing force and drive device power are obtained. In a third step, the stored curves are analyzed in the aspect of reaching of the threshold values of the force curve, the speed curve or the power curve of the drive device, and the adjustment is adapted to, so that the force curve, the speed curve or the power curve approaches the corresponding threshold values until one of the force curve, the speed curve and the power curve reaches the threshold value. The method is repeated from the second step until one of the threshold values is reached a
