Injection moulding technology
Liquefying plastic before pressure-injecting it into the required shape, and allowing it to cool – the advantage of widespread injection moulding technology is that finished plastic parts can be produced with high precision in large quantities for a relatively low cost. However, the injection moulding process is complex. High demands are also placed on the drive and automation technology used. KEB’s high-quality hardware and software solutions ensure that injection moulding processes run smoothly at all times.
KEB – Your injection moulding partner
Injection moulding machine
The clamp and plasticising form the central components within an injection moulding machine. This requires a dynamic drive system that meets the requirements for sequential behaviour and high force density. KEB's system solution also offers, among other things, servo pump solutions for hybrid machines and the possibility of DC coupling for all-electric or hybrid injection moulding machines in order to save energy. The air- or water-cooled DL4 motors are particularly powerful, providing the right amount of power for injection moulding with low mass inertia and high torque.

Downstream equipment / handling systems
Programming robot kinematics controls has never been easier. With its ready-made PLC components, KEB provides everything you need for smooth and fast commissioning. The system solution is rounded off with KEB’s high-performance geared motors. More information about downstream equipment
Servo pumps
Control oil quantities and pressure: This is made possible by servo pumps which – in conjunction with frequency converters from KEB – vary the speed of aggregates accordingly. Information about the servo pump

Injection moulding machine
KEB provides the right solutions for all types of injection moulding machine, from all-electric machines to hybrid machines (electric and servo-hydraulic) to hydraulic machines, for which corresponding servo pump software is available. Fully electric solutions with non-linear torque pre-control are ideal for controlling the clamping unit and consequently reducing the machine cycle. In addition, high-performance DL4 motors are available which are characterised by high torque and low inertia. With the resulting high level of dynamics, the motors are perfectly suited to the requirements of injection moulding machines.
Servo pumps
In industrial oil hydraulic systems, pumps are typically operated via asynchronous electric motors with a fixed speed at the mains. Oil quantities and oil pressure are controlled in this case using valves and/or adjustable pumps, and a high proportion of energy is introduced into the system in the form of heat. In conjunction with KEB COMBIVERT F6 drive controllers, the speed of the units can be varied so that oil quantities and pressure can be precisely regulated to the machine’s requirements. This reduces the machine’s cycle time and minimises energy consumption and noise levels.
Downstream equipment
Different robot kinematics such as linear robots are used for removing parts from injection moulding machines. The necessary PLC modules are already provided by KEB. This enables fast and low-maintenance programming and development. The ready-made motion modules also allow direct commissioning of several axes. Another advantage: The servo and gear motors optimally matched to them are also available from KEB. According to the motto "Everything from a single source".
