FRITZ HANSBERG stands-up among the very leading manufacturers of green sand molding equipment.
More than thirty years of experience in the design and manufacture of green sand molding facilities make the name of FRITZ HANSBERG's one of the most respected in the industry worldwide.
Nearly fifty FRITZ HANSBERG molding lines are currently in production with many world-class foundries in Europe and overseas, producing the widest array of cast iron and aluminum castings, from automobile and commercial vehicle, to general engineering, municipality, and domestic heating.
Based upon a three-phase molding sequence featuring pre-fill, shoot, and squeeze, the HANSBERG Molding System is a consolidated, foundry-proven mold making technology which ensures the production of castings consistently complying with the strictest quality control requirements.
- Excellent dimensional accuracy
- Unmatched surface definition
- Minimum weight variation.
Each of the phases of the molding sequence contributes to the production of top quality molds that reproduce the most intricate patterns, with minimum regard to variation in the characteristics of the sand.

Automatic core blowing machine with vertical split of the core box, including moulding station, based on the Shell-Moulding process.
The mobile unit that holds the core box and the reservoir attached to the rods rotates 180° to spray at any point between the bottom and the top and to return to the bottom, tilting +/- 45° to make it easier to empty the cores, if required.
The machine is equipped with a direct flat spray reservoir and blowing head cooling system.
The pneumatically-powered automatic loading system also includes a loading hopper.
The mobile support, attached to the half-box containing the core, is equipped with a device to overturn it onto the belt using cylinder-driven extractors. Heating is generated by an independent burner frame for each half-box, fed by an air and gas mix (LPG or NATURAL GAS) with heat regulation.
The machine is equipped with a 24V control panel for manual or automatic operation in a single or continuous cycle in addition to a hydraulic control unit to operate the cylinders while wheels with a chain and an inverter are used for the overturning operation.
From the protective booth the operator can access the machine while maintaining the safety level established by CE regulations.

The "Revolution" range of cold chamber machines manufactured by IDRA is another technical development available for customers to give them the competitive advantage.
Different from the traditional toggle machines, the clamping is individually mounted on the 4 tie bars with hydraulic actuators of reduced oil volume to guarantee the same clamping strength as standard toggle machines.
Advantages:
- Automatic compensation of parallelism
- Automatic compensation of thermal expansion
- Shorter start-up times
- Faster closing and opening speeds
- Longer strokes of moving platen
- Less maintenance due to simple construction and less moving parts.
- Shorter total machine length in comparison to a standard toggle machine.

V-process molding takes advantage of an abundantly available, totally reliable and almost free natural phenomenon to bind molding sand in place... Atmospheric Pressure!
With V-process molding you eliminate many of the costs and problems associated with conventional green sand and no-bake molding.
Because the V-Process uses clean, dry unbonded sand, you can forget about mullers and mixers, and costly sand reclamation and reconditioning equipment. Most V-Process users require only sand cooling and transportation, dust collection and simple screening to remove tramp metals.
Molding equipment is simple too. It can be limited to as few as five items (a vacuum system, Film heater, vibrating table, pattern carrier and flasks) or automated for higher production. There is no need for heavy, noisy jolt squeeze equipment, ramming of slingers.
The molding media is clean and dry therefore shakeout equipment is usually nothing more than a grate to allow the sand to flow away from the casting and back into the sand system. Fume and odor control is unnecessary in most applications.
Low operating cost
You not only save on the cost of sand binders but all of the cost of sand mixing, testing and disposal/ reclamation. Even pattern life is extended because the sand never touches the pattern and it is never subjected to the rigors of a conventional molding machine. Finally, V-Process produces castings with fewer imperfections and less scrap.
