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

At WAREMA, more than half a million Luer Locks are manufactured annually – essential connecting elements in medical technology. The production requires extreme precision whilst delivering high production volumes.

The electric, tie-bar-less victory electric injection moulding machine delivers this precision by electric drives on the injection unit. The uniform closing force distribution of the tie-bar-less closing concept ensures optimal and even force transmission to all cavities of the mould, which improves the dimensional accuracy of the parts within one shot. This not only guarantees high product quality but also outstanding Overall Equipment Effectiveness (OEE).

With its tie-bar-less design, the victory electric offers optimal access to the mould area. This facilitates automation, whether in the removal of parts or in the loading of the mould with inserts. Crucially, compact automation solutions with minimal space requirements are possible, providing full flexibility for larger end of arm tooling. The tie-bar-less mould area enables an accelerated mould change. The shortened downtime during mould change means a significant efficiency increase, improved Overall Equipment Effectiveness and ultimately production growth.

Additionally, the tie-bar-less technology allows the use of large moulds with comparatively low clamping forces. The versatility of more compact injection moulding machines is particularly advantageous in cleanroom applications, where space is often limited.

To ensure the highest product quality with simultaneously clean, precisely moulded plastic components and processes, the victory electric relies on a unique machine concept.

• Tie-bar-less, free mould area: less air turbulence in the sensitive mould area

• Precise machine components: minimal particle abrasion and easy-to-clean machine design

• Encapsulated toggle: no leakage of lubricants

• Cleanroom package: optional for meeting the highest cleanliness requirements

The elimination of the tie-bars allows easy access to the mould area, simplifiying automation and thus producing shorter cycle times. Saving both time and energy.

The victory electric is also equipped with highly efficient servo-electric drives, which not only have low energy consumption but also possess impressive precision. Thanks to the high accuracy in the injection process and the uniform clamping force distribution, the machine achieves a very low reject rate. This lowers material waste whilst improving energy efficiency and productivity.

The e-flomo temperature control system installed at WAREMA ensures uniform mould cooling. Due to the precise temperature control, cooling efficiency losses are reduced to a minimum and temperature errors are avoided. This contributes significantly to reducing rejects and maintaining consistently high part quality. Ensuring an economical and sustainable production.
