MEX 2017 Machines to provide flexibility for mould makers
Machines – Krauss Maffei will present its CXZ 80-380/180 hydraulic injection moulding machine that will demonstrate the advantages of a plastics-specific component design using the example of a two-component application. Another highlight will be the new all-electric PX series injection moulding machine for universal moulds.
The CX series is a compact, efficient and flexible two-panel machine with a clamping force range from 350 to 6500 kN. At the joint booth of the VDWF (German Tool and Mold Making Association), a CXZ 80-380/180 machine with a clamping force of 800 kN will demonstrate the advantages and disadvantages of a plastics-specific or non-plastics specific component design, using a two-component application. The component is separated by colour. The plastics-specific design is marked by the blue zone, the non-plastics specific area by a red zone.
The design of the CX series, which is both compact and efficient, also offers advantages for the fast and convenient set-up of moulds. This is supported by the good accessibility of the ejector area and the option of easily fastening additional ejectors or unscrewing units. The wide doors, which can be opened all the way, permit easy access too.
Furthermore, the CX series allows for the use of large plates/panels and high mould weights. Plasticising units can be easily replaced in CX machines, thanks to their quick mould clamping systems using cylinders and their adaptation to small screw diameters. Here, the MC6 control system automatically detects the installed screw size and makes the necessary adjustments automatically.
Optionally, the CX can be equipped with an enlarged space for the clamping unit, which in turn, allows for enlarging the inside diameter and increasing the opening width. In addition, the good plate parallelism and the smooth-running clamping unit ensure that mould wear is minimised, the company notes.
The new PX series is an all-electric made-to-measure machine
According to Maffei, this series features a combination of the advantages of an all-electric injection moulding machine with maximum modularity. Processors benefit from high precision, productivity and flexibility in all production phases. The high flexibility also continues with the operation of the moulds. Thus, the large mould clamping plates permit universal mould operation. Even the widest variety of moulds with large or small mould heights can be set-up individually. Easy and fast set-up of the moulds is provided for by the accessibility of the clamping and ejector areas. Automatic mould height adjustment using the MC6 control system and the process designer function for a graphic, user-configurable sequence programming provide further advantages in the operation and easy process set-up.
The PX series also allows for the insert of high-performance moulds in a standard machine. For example, powerful servo-motors provide fast mould movements and dynamic clamping force build-up. A clamping motor with brakes makes the mould installation in the presence of clamping force even safer, the company adds.
Krauss Maffei will be in hall 6, booth C53.
