TF Two Platen Toggle Free
Die Casting Machines

TF Two Platen Toggle Free Die Casting Machines

Key Benefits

Closing force from 1000 to 5600 tonnes

Two platen toggle free machine

SC 3.0 shot end system for absolute injection precision and speed

Compensates for geometrical imperfection of the die and its thermal expansion, making it extremely flexible

Key features

The TF toggle free die casting machines are reliable, rigid and flexible.

Reliable: the absence of the connecting rod system and the reaction platen makes the structure leaner, reducing the number of wear parts. 

Rigid: the bigger and shorter tie bars make the machine extremely rigid, ensuring greater die closure for improved casting quality and minimal scrap rate.

Flexible: thanks to 4 independent nuts, the TF die casting machine is able to compensate for geometrical imperfection of the die and its thermal expansion, adapting to different working conditions. 

Compact:  reduced footprint with the same closing force as the die casting machines with toggle.

Quality: high quality machine construction, made of forged or cast steel platen with coating to increase hardness, and special steel alloy tie bars.

Precise: equipped with SC 3.0 shot end system to maintain absolute consistency and repeatability of the shot, ensuring highest quality of the casting.

The TF die casting machine can be supplied as an automated solution: a fully automated cell that integrates all peripheral devices, from the furnace to automatic deburring with pieces ready for machining.

Applications

Toggle free high pressure die casting machines are ideal for a diverse complex casting production and when the die is frequently changed.

Some applications include:

Automotive parts: Engine blocks, gearboxes, oil sumps, engine support, structural parts (battery housing, car roof, shot tower, pillars).

Other industries: Radiators for household heating, escalator steps, chassis and components for electronic devices, telecommunication components, household appliances, electric motors.

Our Toggle Free series offers the latest technology in high pressure die casting and is ideal for foundries looking for reliable and efficient production of high quality aluminium castings.

The TF series of toggle free die casting machines includes a wide range of models with closing forces from 1000 to 5600 tonnes.

The TF two platen die casting machines are compact, flexible and extremely efficient. The hydraulically driven closing force keeps the machine steady, ensuring more precise closure of the die, minimising scrap rate and ensuring highest quality of the casting.

Flexible and solid for greater productivity

  • TF's high repeatability increases your plant's productivity and reduces scrap rate.
  • Thanks to 4 independent nuts, the TF die casting machine is able to compensate for geometrical imperfection of the die and its thermal expansion, adapting to different working conditions. 
  • Enhanced hydraulic system provides greater reliability and uptime at your site. Rock-steady, rigid and solid performance ensures consistent production and on-time delivery of high quality castings to your customers.
  • Reduced footprint with the same closing force as the  toggle machines ensures optimisation of space at your foundry.

Reliable and LEAN for optimal performance

  • The leaner structure of the machine reduces wear on parts which leads to reduced maintenance costs and increased uptime. 
  • Our friendly and reliable support services, operator training and foundry technology service agreements will help you optimise your productivity and performance.
  • Our control system and easy to use operator panel comply with the latest standards minimising complexity, and ensure the highest precision.

Supplied with HMe

A  machine control system with advanced data management and diagnostics capabilities. HMe offers real-time storage and powerful analysis of machine and process data, as well as the integration of peripheral and mobile devices. It opens up the possibility of controlling the whole die casting process holistically through a single user interface.

Quality and solid reliability as standard

Our TF machines are built using forged or cast platens made of only certified alloy steel to ensure absolute quality. All our platens have additional coating for increased hardness, greater resistance to wear and to prevent lubricant damage.

Tie bars are made of special steel with a rolling thread - state of the art technology for higher tie bar strength.

Absolute injection precision

Equipped with the SC 3.0  shot end that ensures: 

  • Maximum consistency and repeatability in the different shot stages which guarantees uniform casting quality.
  • Increased reliability of the injection: the use of flexible pipes avoids breakages that might occur during high pressure peaks.
  • Easier access to parts of the injection system that requires maintenance, this ensures a LEAN maintenance process and increased machine uptime.

Efficiency all round

Rigid construction of the Closing Unit secures better closing of the die to reduce scrap rates and flash.

A quicker die change is made possible with the tie bars automatic removal option to allow more comfortable and LEAN die change. 

 

Operator-friendly

The control system is tailored to your needs. It is based on a standard Siemens or Allen Bradley PLC with software specifically designed for die casting. Its user-friendly design makes it easy to operate and upgrade as it is made of standard control components that offer reliability and availability of supply.
