The now more compact ENGEL e-mac all-electric injection moulding machines are specially equipped with particularly powerful servo motors for optimum overall efficiency (image via ENGEL)
In October 2020, ENGEL will launch its next generation of its family of all-electric emac injection molding machines for the production of straw tips in challenging applications
.
The e-mac offers maximum flexibility to meet individual requirements and is now even more compact
.
The quality of the pipette tip depends largely on the precision of the injection molding process
.
Therefore, in this field of application, an all-electric injection molding machine is the preferred solution, and cost-effectiveness is a decisive factor in choosing a machine
.
With the e-mac model, ENGEL has in its portfolio an all-electric injection molding machine that combines high output and energy efficiency with an extremely compact machine design, ensuring maximum performance even in clean room environments.
Minimize unit cost
.
Now ENGEL has further reduced the footprint of the e-mac machine
.
Among the electric injection moulding machines on the market, the new generation of e-mac injection moulding machines is the most compact in the world in the entire range of machines of different performance classes
.
All movements of the ENGEL e-mac injection moulding machine, including nozzle movement and ejection, are carried out by servo-electric drives, which means that the overall efficiency of the machine is very high
.
If required, the servo hydraulics can be integrated into the frame without additional space
.
The injection unit of the ENGEL e-mac was developed from scratch with a focus on providing better power
.
It is available in 3 performance classes, so the machine can be precisely adapted to various requirements for the widest range of applications to achieve the highest overall efficiency
.
Fully automated with minimal footprint

The e-mac 180 proves the performance of the next-generation machine by fitting a pair of 64-cavity precision molds supplied by Tanner (Feuerthalen, Switzerland) for the production of polypropylene pipette tips
.
The entire cycle time is 6s, which is exactly the range in which the e-mac injection molding machine takes full advantage of it
.
For precision applications with cycle times exceeding 4s, the e-mac is often the most economical solution in the field of all-electric injection molding machines
.
In addition to medical technology, the machine is mainly used in the fields of packaging, electronics and technical shaping
.
Automation made an additional contribution to the extremely small footprint of the production cell on display
.
An ENGEL viper 20 linear robot removes 64 pipette tips from the mold and transfers them into an integrated compact unit, which is arranged according to the cavity
.
ENGEL's new automation cell can be designed to order, it contains all the automation components and downstream process units, such as quality control, pallet servers and carton changers, and is much narrower than traditional safety guards
.
Standardized assembly ensures that molds can be quickly installed in the event of a product change in the production cell
.
Intelligent assistance improves machining consistency
Intelligent assistance improves machining consistencyUpon customer request, ENGEL offers application-specific production cells that, in addition to injection molding machines and automation, also include digital and networked solutions
.
For the production of pipette tips, the production cell is equipped with iQ weight control and iQ flow control intelligent assistance systems
.
iQ weight control readjusts the melt volume for each shot, ensuring a consistently high quality of the injection molded product
.
iQ flow control automatically adjusts the temperature difference in the cold water manifold circuit, for this, the software uses the measured values determined by the e-flomo temperature-controlled water manifold system.
The pump speed in the e-temp temperature control unit can also be automatically managed to reflect the demand for energy
