ACE
The ACE is a close relative of the Seiatsu family of flask moulding machines from Heinrich Wagner Sinto. Through the optimised movement and action sequence, the machine achieves the shortest cycle times with low energy consumption, whilst also guaranteeing perfection in every mould. 

The moulds are filled with sand fluidised by compressed air. This results in increased flowability of the sand and therefore allows more complex model geometries to be filled.
Aeration Compact Energy
With this process, the sand in a storage hopper is fluidised through air-permeable filter plates on the insides of the hopper. The sand is filled with a low positive pressure through slotted nozzles arranged on the side of the contour cylinder/cylinders. An evenly and completely filled mould is compacted through the lowering of the two main cylinders and the contour cylinder. The press on the model side closes and completes the moulding process through an additional lowering movement of the filling frame and the moulding flask is lifted from the model. At the end of the lifting movement, the hopper sand is refilled and the model change is initiated before the next mould cycle starts.
Advantages of the ACE technology
Mould quality satisfies the highest requirements
Consistently high mould strength is achieved through the various possibilities of the press on the sand ridges and model-side press. Through precise, vibration-free mould separation the ACE is capable of establishing thin-walled cast pieces with minimal mould draft angles.

Increased energy efficiency
The design’s utilisation of gravitation during the pressing process increases efficiency. The energy consumption is significantly reduced and makes a major contribution to a reduction in energy costs.

Reduced emission values
The noise level is less than 80 dB(A). The working environment remains free of vibrations due to the enclosed design. A hermetically sealed chamber reduces pollution caused by separating agent and dust.

Metering as required - excess sand is a thing of the past
Almost no surplus sand arises during sand filling. The quantity of sand required to fill a mould is precisely controlled with a control system, so that the sand that is scraped off the rear of the mould by the sand scraper is reduced to a minimum.

Compact design
With its compact dimensions, the ACE can also be installed without a foundation pit. A significant advantage when replacing the moulding machine in an existing moulding system. Minimal space requirements together with generous accessibility for maintenance are no contradiction.

Sand filling that is kind to the model
The fluidised sand has a significantly less abrasive effect on the model contour and therefore results in a longer service life for the models. The resultant dimensional accuracy is reflected 
Available moulding machines that utilise the aforementioned processes include not only fully-automatic high performance moulding machines, but also simple series moulding machines for manual and semi-manual operation.

The FDNX moulding machine is the smallest machine for the production of flaskless moulds. It is optimally suited for smaller cast products with few cores.

Equipped with a control system with modern operating panel, the FDNX reflects the latest engineering standard. A hydro-pneumatic compaction system complemented by sand filling with the AERATION sand filling technology, guarantees the exceptional mould quality.

The FDNX can be operated as a stand-alone machine or in a manual or fully automatic system environment.

The FBO moulding machine range covers a broad spectrum of cast products. With a range of machine sizes, the system can be optimally tailored to the production program.

With an ergonomically designed workstation, in particular the insertion of cores in the lower mould halves is possible. Automation is also possible in this area, to increase the performance capability.

Equipped with a control system with modern operating panel, the FBO reflects the latest engineering standard. A hydraulic compaction system complemented by sand filling with the AERATION sand filling technology, guarantees the exceptional mould quality.

FBO moulding machines are particularly well suited for use in an automated system environment. 

Vacuum PROCESS moulding machines and lines
Our individual and flexible system layouts offer the optimum solution for every task. Be it fine synthetic cast or heavy-duty machine components - every system is individually planned in line with requirements. At the same time, the existing building structures and material flows are taken into account, alongside the workplace geometry. The V-PROCESS moulding machines and systems can be divided up into the following variants:

Test moulding machines
These are optimally suited for prototype production, pilot series or individual manufacture and small series of cast parts. Moulds for cast parts of just a few grams up to multiple tons in weight can be produced with these machines. The moulding process is supported by operator interventions. The moulds are handled entirely with hoists.

Attainable outputs range from one mould per day up to three moulds per hour.

Typical applications are the production of special cast parts, synthetic cast or the certification (also approval) of series cast parts.

Semi-automatic moulding machines and lines
are characterised by a semi-automatic operating principle. All steps take place automatically within the moulding machine. Transferring the moulding flasks into the casting and cooling area, as well as emptying, take place with the aid of hoists. The systems can be expanded on a modular basis for a higher degree of automation.

These systems are optimally suited for the production of cast parts with high weights, and for small series and moderate unit quantities of cast parts from all weight classes. Attainable outputs range from one to eight moulds per hour

Typical products are wearing parts, valves and fittings for the oil and gas industry, as well as components for general machine construction (e.g. printing and textile machinery).

Fully-automatic moulding systems
In these moulding systems, the processes of mould production, mould transport into the casting and cooling area, and emptying all take place automatically. Standard activities on the mould, such as numbering, finishing coating or inserting the cores, can take place manually or automatically.

The efficient series production of cast parts with the minimum in manual intervention is guaranteed with these systems.

Attainable outputs range from six to sixty moulds per hour.

Such moulding systems are used for the series production of cast locomotive rails, fittings and valves, bathtubs, cast automotive parts and much more besides.

The HWS product for mechanical sand regeneration is suitable for freeing sand grains from any casing shells. The aim here is to achieve a condition with the reclaimed sand that is similar to new sand. This can then be used for example as a basic moulding material or as a substitute for new sand (e.g. in core shops).


The sand is continuously and uniformly transported into the machine via a small vibration channel (no batch operation). Using a fast-turning rotating drum, the inflowing sand is transported outwards to the drum wall due to the centrifugal forces generated. Ceramic press rollers exert force on the sand layer upon reaching the target full level, and this results in the sand grains rubbing on each other. This friction process frees the sand grains of their casing shells particularly gently. The variable pressure is highly advantageous here, because the process can be aligned with the individual characteristics of the used sand. This helps to avoid grain breakage for example, and ensures a high level of regeneration efficiency. 

Thanks to the use of particularly high quality ceramic components, it is possible to achieve very long service lives of the parts that come into contact with the rubbing sand. These are manufactured in the group’s own ceramic production.

The regenerated sand and binder residue are displaced by the continuous incoming flow of sand from the rotating drum, and they drop onto the fluidisation bed. This is located in the bottom part of the machine and transports the sand and binder residue onwards through the machine until beneath the deposition chamber.

A dedusting unit connected to the deposition chamber finally separates the fine particles and dust from the sand grains, which are too heavy to be extracted here. With the aid of the dedusting power setting, it is possible to realise target grain distributions here if necessary (reduction in the fine portion, dust and small grains of sand).

The high quality regenerated sand is now available at the outlet of the machine and can be freely reused in the resource cycle of the foundry.

The following products are available for a range of automation levels and pouring quantities:

P-series, is a pouring machine for semi and fully-automatically controlled casting 
        for all grades of iron and light metals.

        for all grades of iron and light metals.

 

Leading-edge system and automation technology, as well as data communication with a superior ERP and QA system and data coupling naturally take place in accordance with the latest communication standards.

The design
The tilting casting machine from the PLS-series is a fully automatic casting machine for filling your die. Depending on the die size, the casting machine is available in two sizes “PLS-I” and “PLS-II”, with varying dimensions, as well as closing and opening forces. The centrally located machine pivot point in combination with the precisely controllable servo drive guarantees even and smooth die filling, which minimises the oxide and gas absorption during the casting process.

The characteristics of the tilting motion can be individually adjusted to your requirements by varying the tilting speed and behaviour. In connection with the optional rotating casting ladle, it is possible to satisfy the highest quality demands. Rotating the tilting casting machine is controlled here independent of the casting ladle rotation. This gives you greater flexibility for your casting process. The compact and robust design with the pivoting machine top section guarantees economical and ergonomically efficient system operation.

Linear and rotary table configurations can also be realised for maximum productivity.
