Disadvantages of a Hydraulic Press

Hydraulic presses are powerful machines that can be employed for a variety of tasks. However, these tools also have their drawbacks.

When purchasing manufacturing machinery, it is essential to be aware of both the pros and cons. This article will help you better comprehend the advantages and drawbacks of a hydraulic press.

1. Excessive Noise

Hydraulic presses are a widely-used metalworking machinery type. They find applications in aerospace engineering, appliance, automotive manufacturing, ceramics, food and beverage processing, industrial marine medical military defense packaging pulp & paper production.

One of the drawbacks of hydraulic presses is their noise level. This can be especially evident when multiple presses are in operation, creating an unnerving environment for operators and anyone working nearby.

However, there are ways to reduce the noise generated by a hydraulic press. Some of these solutions include personal ear protection, redesigning tooling to stagger punches and adding cushioning.

Other methods, such as placing the hydraulic pump in a separate room away from other workspaces, can also be successful. Finally, installing an acoustic enclosure may help control noise caused by a hydraulic press; however, this solution is expensive and difficult to implement.

2. Excessive Heat

Excessive heat can damage hydraulic fluid, destroy seals and increase wear on pumps and other components. It also cooks the oil, breaks down additives and accelerates oxidation of the fluid.

Common seals are designed to operate below 180 degrees Fahrenheit, so any temperature above this will reduce their ability to resist abrasion, tear and friction. This can result in seal failure, leaks and line issues.

High temperatures can also thin the oil's viscosity, decreasing its ability to lubricate system components. Ultimately, this decreases the life of components within the system and drives up repair costs.

Hydraulic systems can be designed to compensate for heat losses through input power. However, this requires that the heat dissipation rate remain higher than the heat load.

3. High Maintenance Costs

Hydraulic presses may seem straightforward enough, but they can become expensive to maintain over time. That is why it is essential that you consider the true costs when selecting a new press for your shop.

For instance, a hydraulic pump used for heating room temperature water will have different maintenance costs than one using a hot blast furnace. Furthermore, energy efficiency should be taken into account during the design phase.

Hydraulic presses are an excellent investment for your shop if you can ensure they run optimally. Developing a proactive preventive maintenance schedule is recommended to avoid downtime and costly repairs.

4. High Risk of Injury

Hydraulic presses are essential tools in many industries. They can be used to form, mold, punch, drill, straighten and cut large pieces of metal or strong material with ease.

However, these machines also pose serious safety hazards to operators and employees who work near them. To guarantee maximum operational efficiency and safety standards for these machines, specialized training and regular maintenance is necessary.

Hydraulic presses offer many benefits, but they also pose serious safety risks if used incorrectly. That is why having effective machine guarding solutions in place for each press your team uses is so critical.

To guarantee safety and abide by OSHA standards, machines should be fitted with failsafe locking systems. These can help reduce the risk of injuries or amputations if a machine malfunctions or is misused.
