FT Series

FT Series

The FT DESMOFORMER simultaneous forming and punching thermoforming machine guarantees outstanding product dimensional precision.

The lower titling platen turns through 75 degrees permitting precise rapid ejection of the formings, which are then transported to the stacking unit.

The (patent pending) pivot system uses a combination of servomotor driven cams and levers. It guarantees absolute precision of movement and repeatability and a controlled distribution of forces during the platen movement and cutting phases of the cycle.

The plug movement is controlled by servomotor and provides an even and controlled distribution of the material inside the mould cavity.

Different plug speeds and times can be programmed, which can considerably improve the aesthetic appearance of the forming plug marks due to contact of the plugs with the material.

Differentiated stacking systems can be supplied to optimise the machine speed in relation to the size and format of the items to be produced.

All the machines can be supplied as an IN LINE version, constituting a “production island” starting from the raw material feed in granules through to the packaging of the finished product , including the in-line recycling of the granulated scrap.

INTEC - In-line thermoforming machines

The IN-LINE plant is a true "production island" comprising all operational components that transform the raw material granules into the finished product. 

This production system is the optimal solution for managing medium and high production levels allowing the most cost-efficient usage of raw materials, energy consumption and consequently reducing the personnel cost rate as well as the required working space.

The IN-LINE plants are manufactured for PROGRESSIVE IN LINE productions starting from granules passing through extrusion, calendering, thermoforming, stacking, scrap grinding and ultimately feeding the extrusion with the grinded material generating a number of proven advantages for the end user that can be summarized as following:

Thanks to immediate sheet extrusion we are able to obtain high temperature uniformity, reached in the very center of the sheet mass. This provide a more homogeneous distribution and better stretching of the material during the forming process contributing to better mechanical and aesthetical characteristics of the final product.

The optimal distribution enables further thicknesses reduction of the sheet maintaining the same characteristics of the material and turning it into a lighter piece. The recycled material coming from the grinded scrap prevents material pollution and thereby improving the product quality.

With the extrusion line, the sheet unwinding station is eliminated. The residual temperature of the extruded sheet is fully used and therefore it is not necessary to further submit the material to intensive heating.

The downtime due to reel changing is eliminated and in order to reduce waste immediate action can be taken when any anomaly is being detected on the extruded sheet.

The compactness of the production line and the elimination of the storage reels and waste management units allow a considerable increase of space savings.

Once fully operational, a single operator can manage the complete production line.

Cylinders and screws are made of nitride steel. Special versions with bimetal and steellite (hard metal tipped) are available on request for the processing of filled materials.
Particular care has been dedicated to the designing of the screw profile in order to obtain the best and optimum homogenising and plasticization of the material.

Special stainless steel covers, easily removable for maintenance operations, protect the heated zones.
All extruders are supplied with continuous hydraulic screen changer to avoid material flow interruption. A separate hydraulic power pack for the filter exchange is also supplied and can operates others co-extruders. 

A gear pump system is supplied as standard on all the main extruders. This pump eliminates the possible pulsations into the melt assuring constant and uniform feeding of the extrusion die head. 

In case of more extruders, a co-extrusion feed block is installed before the flat die head, in order to distribute the material flow on different layers.
The extrusion flat die head has a flexible lip adjustable by bolts of differential thread to control the sheet thickness, the width is manually adjusted by proper deckling bars.

The most important advantages of the new generation of WM N.EXT extruders may be summarized as follows:
-          Higher productivity
-          Energy saving (less cooling and less installed power)
-          Wear reduction
-          Very good self-cleaning
-          High percentage of regrind possible.

Curiosity, the source of research and development: a world premiere at K 2016, the launch of a new WM’s thermoforming machine

WM Thermoforming Machines, the Swiss company based in Stabio, achieved a prestigious goal at the end of July: the delivery of the 110th IN-LINE plant system for extrusion and thermoforming, model INTEC 900/3, for the production of two colors PP cups, to a customer in North America.

And July 2016 will be definitely remembered in the story of WM also for another success, a new record in the sales volume.


But WM prefers to talk of another “brick” that has been added to the growth of the company, established in 1983.

A solid family owned company on its third generation, which can rely on a loyal and growing work force, a company committed to the preservation of high quality standards, to the improvement of its after-sales service, but most of all to the continuous research and development in the field of thermoforming technologies and packaging.


To confirm this, there is the evolution of the vacuum pressure forming machines with steel rule cutting blades, model FC 600/780/1000 integrated with 2 and 3 axes robot, projected and realized by WM, which have reached the third generation, as a result of the studies to increase speed and precision in the stacking.

A very good answer from the market arrived also from the model FC 780 IM and FC 1000 IM that allow in-mould forming and cutting, guaranteeing great precision and high productivity, thanks to the cutting presses with clamping force up to 130 Ton.


The same effort has been put in the punch and die thermoforming machines with tilting mould, model FT 500/700/900 completed by the two new stacking systems projected as an answer to the different market requests.

The model ES7 (Easystack) has been developed for the customers who have the need of frequently change the mould and it promise low investment costs in the stacking tools and fast mould changes.

The model MSv (Multistack) allows the stacking of both containers than lids, assuring a precise stacking and unloading on the packaging lines.

Moreover the version D of the FT 900 is ready to be put on the market, the spearhead of the FT series. The FT 900 D version has been rationalized to produce cups and containers in PP by using a sheet thickness of more than 2 mm.


Improvements also on the IN-LINE plants, which has been implemented with the new high efficiency and low consumption extruders model N.EXT 30, 45, 75 and 90 mm that can produce up to 900 Kg/h of PP.


And if that's not enough, WM following the spirit of continuous innovation, for those who are even more curious about technology will reveal at K show from 19-26 October a newly designed thermoforming machine with tilting platen: the model TWIST 700, born to produce containers in PP, PP/EVOH and PET that requires very high qualitative standards and narrow dimensional tolerances.

The visitors can find more details about the features of this new machine at Hall 3 Booth A16, where it will be the moment to meet, in a friendly atmosphere, new and well-established customers interested to the excellence of thermoforming.


Obviously on the booth there will also be video and documentation about the whole WM’s thermoforming machines range and IN-LINE plants, leitmotiv the theme of the advertising campaign “Nature-like protection”, represented by a chestnut enclosed in its urchin. The urchin protect its fruit, just like the plastic packaging protects the products contained.


But WM is looking forward. We circle back to where we started, in the period before and after K Show in WM headquarter it will be possible to see a working IN-LINE extrusion and thermoforming plant for the production of PP cups. While, for those who might be interested in an IN-LINE plant with co-extrusion, the appointment is on December 2016 with the a new INTEC FT 900/3 for PP and PS.
