Electric precision and tie-bar-less efficiency as key success factors

At WAREMA, more than half a million Luer Locks are manufactured each year – essential connecting elements in medical technology. This production demands exceptional precision while maintaining consistently output.

The electric, tie-bar-less victory electric injection molding machine delivers this precision through its electric drives on the injection unit. The uniform clamping force distribution of the tie-bar-less closing concept ensures optimal and even force transfer to all cavities in the mold, improving the dimensional accuracy of each part within one shot. This not only guarantees outstanding product quality but also maximizes Overall Equipment Effectiveness (OEE).

The victory electric offers optimal access to the tool area thanks to its tie-bar-less design. This design enables easy automation - whether for part removal or or insert loading – and allows for compact automation solutions with minimal space requirements. Full flexibility for removal movements and large gripper systems ensures efficient production processes. The tie-bar-less design also simplifies and speeds up tool changes, significantly reducing downtime and increasing Overall Equipment Effectiveness (OEE) and productivity in series production.

Additionally, tie-bar-less technology allows the use of larger tools even with low clamping forces. This makes compact injection molding machines more versatile, particularly for cleanroom applications where space is often limited.

To ensure top product quality while maintaining clean, precisely molded plastic components and processes, the victory electric is built on a well-thought-out machine concept featuring:

• Tie-bar-less, open tool area: reduces air turbulence in sensitive areas

• Thoughtful component design: minimizes particle generation and enables easy cleaning

• Encapsulated toggle system: prevents lubricant leakage

• Cleanroom package: optional for meeting the most stringent cleanliness requirements

The elimination of the tie-bars provides easier access to the tool area, simplifies automation, and shortens cycle times. In addition to saving time, it also reduces energy use.

Moreover, the victory electric is equipped with highly efficient servo-electric drives, which not only consume less energy but also deliver outstanding precision and dynamics. Thanks to the high precision in the injection process and the uniform closing force distribution, the machine achieves an exceptionally low reject rate. This reduces material and energy waste, sustainably boosting productivity.

The e-flomo temperature control system installed at WAREMA ensures uniform tool cooling. With precise temperature control, cooling losses are minimized and temperature fluctuations are prevented. This plays a key role in reducing rejects and maintaining consistently high part quality. As a result production remains both economical and sustainable.
