High Speed Digital Air to Electronic Converter


HSD-AECONV High Speed Digital Air to Electronic Converter is a high definition air measure system. It supplies dimensional and geometrical measures using pneumatic technology.

The pneumoelectronic Marposs HSD-AECONV is the result of a meticulous engineering study to provide a completely digitized device, where the main advantages are:

  • Absence of linearity error on total working field
  • Very fast reaction time
  • Can be connected to Marposs electronic unit & third-party with digital signal

PEMFC Stack Assembly


Recent years have seen a continuous growth in the use of Fuel Cells Hydrogen systems for a wide range of applications. Their high efficiency and low emissions combined with the fast charging mode makes them particularly suitable in transportation, material handling, stationary, portable, and emergency backup power applications. 

In fact, in many countries there are important projects to drastically reduce CO2 emissions, making H2 a new commodity (Hydrogen society). These reasons suggest the need to implement mass production processes.

In detail, SOFC (Solid Oxide Fuel Cells) are widely used in stationary power and particularly in domestic CHP (Combined Heat and Power) for cogeneration of heat and electricity, thanks to their high efficiency and flexibility to use grid gas as fuel input, for which a dedicated infrastructure is well-established in many areas.

Pem Cell Components


PEM Fuel Cells generate electricity by combining Hydrogen and Oxygen (opposite principle of electrolysis). They are made up of several sophisticated components such as metallic or graphitic BPP (Bipolar Plate), GDL (Gas Diffusion Layer) and CCM (Catalyst Coated membrane) assembled into MEA (Membrane Electrode Assembly).

Battery Cooling Circuit


The proper thermal management of the battery pack is a crucial aspect, on which not only the efficiency and duration of the batteries but also the safety of the whole system depend.

The components of the refrigeration circuit such as cooling plates, chillers and hoses, which are operated either with a water-glycol mixture or with refrigerant gas from the AC system of the vehicle, must first of all be tested to verify their perfect sealing.

Leak proofing of these systems is usually requested because the cooling of the batteries must be guaranteed in the long term and, moreover, leakage of the cooling medium could lead to short-circuits.

Battery Module and Pack


The battery pack represents one of the central elements in the production of an electric power-train, a component whose performance holds the key to future commercial success for PHEV and BEV cars.

It is an element in which the maximum value for this type of vehicle is concentrated, for which it is, therefore, necessary to guarantee the highest quality level by providing adequate quality and process control systems along the complete production chain.

Battery Tray And Cover


The main components of the battery pack housingframetray and cover, represent very critical parts of the battery system, due to the multiple functions they are called to perform.

On the one hand, they must guarantee the possibility to integrate the pack into the car body, ensuring maximum structural resistance and mechanical protection to the battery cells, but with the lowest possible weight.

On the other hand, they must ensure the perfect sealing of the pack, protecting the cells from water, humidity and external contaminants.

EV Transmission


Electrified transmissions are subject to several challenges and requirements.

A combination of international regulations and consumer expectations is driving the demand for reduced noise on all drivetrain components.

Further demand is driven by the growing trend towards EVs and HEVs, where noise from ICE is intermittent or no longer present, and the contribution of transmission noise to overall vehicle noise becomes dominant.

What is true is that the number of gear wheels is significantly reduced in electric vehicles due to the use of one or two-speed reducers instead of the classic manual or twin-clutch gearboxes. In return, these are loaded with torque and RPM’s not previously found in high-volume production.

The other big shift in the automotive industry, the one towards automated driving, is not setting off any alarm bells for gear manufacturers, either. The idea of self-driving cars is currently capturing the industry’s attention, and while it is actually a fascinating trend to follow, having a computer behind the wheel instead of a person is not likely to affect the gears side of the industry too deeply.
