ENGEL is extending its all-electric e-mac injection molding machine series to include a machine with a clamping force of 1300 kN, thus further strengthening its position as a one-stop supplier for applications with electric injection molding machines. The new e-mac 130 is being presented in October to demonstrate a challenging connector component production application.
An ENGEL e-mac 465/130 is producing actuators for Han-Quick Lock brand connector systems by HARTING in a 16-cavity mold for the market launch of the new size. Depending on the connector type, up to almost one hundred actuators are fitted in a single connector housing. They enable particularly fast and easy connection of stranded conductors.
Maximum dimensional accuracy and repeatability
The requirements for the small precision components, which weigh very little and have a strong wall thickness variance, are high. Very high rigidity is required to ensure a reliable function; this is achieved with a polycarbonate containing glass fibers.
All-electric injection molding machines are preferred for the production of connector components in order to ensure maximum dimensional accuracy and repeatability of the filigree component structures. The cost-effectiveness of the machines plays an important role, especially in high-volume production. A wide range of connector variants are produced in large quantities including connectors for use in industrial applications. Connector systems by HARTING are used in ENGEL injection molding machines, for example.
For precision applications with cycle times of more than four seconds, the e-mac is often the most economical solution in the field of all-electric injection molding machines. It combines high output with great flexibility, efficiency and an extremely compact machine design. With the smallest available injection unit, the new e-mac 130 measures only 4,400 mm in length. The clear tie-bar width is 530 x 530 mm. This means that the e-mac 130 offers the largest tie-bar spacing among all-electric injection molding machines with a comparable clamping force.
All movements of the ENGEL e-mac – including the nozzle movement and ejection – are performed by servo-electric drives. This means that the machine achieves very high overall efficiency. If required, a servo-hydraulic unit can be integrated into the machine frame without requiring additional space. The e-mac machine is designed to be particularly maintenance-friendly. Ergonomics were the focus of attention in the positioning of interfaces and the barrel design.
The new size enables ENGEL to adapt the machine even more specifically to the requirements of the respective application in order to leverage efficiency potentials in an even better way. Besides in the electronics industry, ENGEL e-mac machines are used in the packaging, technical molding and medical technology sectors.
