NOVA eT Technology Improves Process and Productivity for IVM

 

Less than six months after the delivery of their first NOVA eT All-Electric machine, County Durham based IVM Ltd has taken delivery of a 280-tonne model.  The machine was purchased to produce an existing under-seat automotive component, with a visible and textured front face.

The tool previously ran on a modern 270-tonne hydraulic machine achieving a 46 second cycle time. There were serious quality issues relating to gas being trapped within the tools cavity.  Despite the addition of gas vents, surface defects resulting from burning were at an unacceptable level.  IVM’s Managing Director, Ian Davidson commented,

“People are surprised when we tell them that we chose All-Electric technology primarily to increase productivity and improve the quality of an existing component.  We all know that these machines use less energy, are cleaner, quieter and have a much smaller cooling requirement than hydraulic models.  These are all contributing factors, but we wouldn’t have made this decision based on these benefits alone.

“We were confident that the proven advantages of the NOVA eT could help us to resolve both the current quality concern, and reduce the cycle time.  Having now eliminated the gas burning issue and also significantly reduced cycle times, we were right to be optimistic.”

“Venting is no longer an issue, as we are able to commence material injection when the tool faces are exactly 0.5mm apart.  This ability to utilise ‘pre-injection’ has both resolved the quality issue and contributed towards the cycle time improvement.

“Most of the cycle time reduction directly relates to the machine’s technological advantages.  For example, the opening stroke has been reduced by a second, the machine ‘relaxing’ the toggles towards the end of the cooling phase.  This means that acceleration is virtually instantaneous once mould opening commences.

“Component ejection now commences once mould open is at 60mm.  This ability to ‘eject on the fly’ also means that there is no dwell between mould fully open and mould close commencing.”

“In summary, the NOVA eT is a ‘fast’ machine when you compare it to a servo-hydraulic equivalent.  All movements have a higher acceleration and deceleration curve, which when coupled with the ability to overlap all phases of the mould cycle, equates to greater productivity.

“All-Electric technology comes with a price premium, only some of which can be justified by energy savings.  Shaving 20% off a cycle time is the real benefit to us, as higher productivity means lower part cost and a quicker ROI.”

Negri Bossi Group CEO, Craig Ward, recently attended an Open Day at the UK’s Rugby facility.  His presentation made a very compelling argument for investment in all-electric technology when machines are below 250 tonnes, citing ‘life costs’ and productivity levels as paramount to European manufacturing facilities and their related overheads.

He went on to postulate that most costings/justifications for the higher levels of investment required were not sophisticated enough and therefore accurate enough to give the correct outcome when deciding between hydraulic or all-electric technology.  When done correctly, the conclusion should invariably be, that in the European market, there was no longer a place for a high-end, sub-250-tonne hydraulic machine.  Investing in machines such as the NOVA eT should future proof the purchasing decision, as the argument will only become more compelling during the service life of the equipment.

The NOVA eT range is available in tonnages between 50 and 350 tonnes and with a choice of injection units.  A 130-tonne machine is currently available to view at Negri Bossi UK’s Rugby showroom.

Negri Bossi at MECSPE 2019

 

Negri Bossi will be present at MECSPE, the first Italian event of 2019, that will take place in Parma from the 28th to the 30th March. Negri Bossi enjoyed an increase in the Italian market share last year and attendance at this event clearly demonstrates the commitment we maintain for the domestic market.

On Hall 6 stand number D05 Negri Bossi will be exhibiting a new machine from the NOVA platform, a NOVA eT 100 tonnes, Euromap 490 injection unit, complete with Tactum Multi Touch controller.

The NOVA eT is a fully electric machine, designed for reliability and longevity. Amongst the key features are:

  • Self-lubricating linear bearings on the moving platen. This ensures cleanliness of the die area, making the machine perfect for cleanroom environments.
  • Robust injection drive system with high speed, high load ball screws.
  • Significant energy savings when compared to conventional hydraulic drive solutions
  • Substantially reduced cycle times due to fully overlapping movements.

The range, from 50 to 350 tons, is equipped with the new TACTUM Controller, user friendly and innovative, with swipe and scroll function and a gesture navigation, which is fast and intuitive. During the event, the machine will produce an ice cream pot, in Polypropylene material. The moulding weighs 25 gr and will be running in a cycle time of 5 seconds. The mould is produced by SCS srl Moulds Construction Society, located near Ancona since 1989. Sytrama Automation, our sister company, will also be on the stand demonstrating a S7 Robot.

MB Spritzgusstechnik invests in a second BIPOWER i2700P machine with automation

 

Established in 2003, MB Spritzgusstechnik in Marktoberdorf (Bayern, Germany), is an owner-managed company. MB develops and produces technically sophisticated injection molded parts from almost all common thermoplastics and recycled materials. The “passion for plastic” of the founder Michael Bechtel, who has more than 25 years of industry experience as a plastic mold manufacturer and plastics technician, is evident in all areas of the company. The factory is passionate about processing recycled materials and re-using raw material to extend life cycles.

MB Spritzgusstechnik ensures they have the most advanced plastic injection technology installed in their factory. This technology enables them to efficiently process recycled plastic to produce Industrial pallets. A 2nd Negri Bossi BIPOWER i2700P-H56000 has recently been installed: a two-platen machine with 27000 KN clamping force and injection capacity of 28 kg in HDPE. The machine is equipped with a servo electric screw rotation and special screw profile for complex recycled materials. A complete Sytrama automation cell with Kuka 6-axis robot completes the installation.

The injection unit is specifically designed to provide a homogenous and consistent melt quality of the recycled

material. This includes a special barrier screw with feeder aids to ensure optimal processing conditions.

The control interface of the BIPOWER model is ergonomic and intuitive, based on an intelligent, self-explanatory menu. Technicians do not require additional training or long learning phases, especially as the system is backed up with the support of the AMICO™ 4.0 system. Amico provides remote technical assistance ensuring a fast response to resolving queries or issues.

MB Spritzgusstechnik has 160 employees and 30 machines installed, and this latest investment in the BIPOWER machine is integral to a strategic move toward sustainable growth and technological advancement.

MB Spritzgusstechnik has continuously renewed their machinery profile, with purchases of both, Negri Bossi Vector and BiPower machines in recent years. MB have an excellent technical competency, and their trust in Negri Bossi is testament to the faith they place in the quality and technology supplied by the company.
Negri Bossi in very proud to continue their collaboration with this prominent and valuable partner.
