What is the storage requirement for a large injection molding machine?

Dec 02, 2025Leave a message

When dealing with large injection molding machines, understanding their storage requirements is crucial for both the longevity of the equipment and the efficiency of operations. As a supplier of Large Injection Molding Machine, I've seen firsthand the impact of proper and improper storage on these complex pieces of machinery.

Environmental Conditions

The first aspect to consider is the environment in which the large injection molding machine will be stored. Temperature and humidity play significant roles in the preservation of the machine's components.

Temperature

Large injection molding machines are made up of various metals, plastics, and electronic components. Extreme temperatures can cause these materials to expand or contract, leading to potential damage. For example, high temperatures can cause the lubricants used in the machine to break down, reducing their effectiveness and potentially causing friction between moving parts. On the other hand, low temperatures can make plastics brittle and increase the risk of cracking.

Ideally, the storage temperature should be maintained between 10°C and 30°C (50°F and 86°F). This range helps to keep all components in a stable state and minimizes the risk of thermal stress. If the storage area is not climate - controlled, insulation and heating or cooling systems may need to be installed to maintain the appropriate temperature.

Humidity

Humidity can also have a detrimental effect on large injection molding machines. High humidity levels can lead to corrosion of metal parts, especially in areas where the machine's protective coatings may be damaged. Corrosion can weaken the structural integrity of the machine and cause electrical components to malfunction.

To prevent humidity - related issues, the relative humidity in the storage area should be kept below 60%. Dehumidifiers can be used in areas with high humidity to reduce moisture levels. Additionally, the machine should be stored on a raised platform to prevent water from pooling around it in case of flooding or leaks.

Space Requirements

Large injection molding machines are, as the name suggests, large pieces of equipment. They require a significant amount of space for proper storage.

Floor Space

The floor space needed for a large injection molding machine depends on its size and configuration. A typical large injection molding machine can have a footprint of several square meters. When planning the storage area, it's important to leave enough space around the machine for easy access. This allows for maintenance, inspection, and any necessary repairs.

A general rule of thumb is to leave at least 1 - 2 meters of clearance around the machine on all sides. This not only provides enough space for workers to move around but also helps to prevent accidental damage to the machine from other equipment or storage items.

Vertical Space

In addition to floor space, vertical space is also important. Large injection molding machines can be quite tall, and there needs to be enough headroom to accommodate the machine without any risk of it hitting the ceiling. The storage area should have a ceiling height that is at least 1 - 2 meters higher than the tallest part of the machine.

Protection from Physical Damage

Large injection molding machines are expensive and delicate pieces of equipment. They need to be protected from physical damage during storage.

Packaging

Before storing the machine, it should be properly packaged. This may involve using protective covers made of materials such as plastic or canvas to prevent dust, dirt, and debris from accumulating on the machine. The covers should fit snugly around the machine and be secured to prevent them from being blown off or displaced.

For more vulnerable components, such as the injection unit and the mold clamping unit, additional padding may be required. Foam or rubber padding can be used to absorb any impact in case of accidental bumps or vibrations.

Storage Location

The storage location should be free from any potential sources of physical damage. This means avoiding areas where there is heavy traffic, such as near loading docks or forklift paths. The machine should also be stored away from areas where there is a risk of falling objects, such as under storage racks.

Maintenance During Storage

Even when a large injection molding machine is in storage, it still requires some level of maintenance to ensure that it remains in good working condition.

Lubrication

Lubrication is essential for the smooth operation of the machine's moving parts. Before storing the machine, all lubrication points should be checked and topped up if necessary. This helps to prevent corrosion and reduces friction between moving parts.

During long - term storage, it may be necessary to re - lubricate the machine periodically. The frequency of re - lubrication depends on the type of lubricant used and the storage conditions.

Electrical Components

Electrical components in large injection molding machines are sensitive to moisture and dust. To prevent damage, the electrical panels should be sealed and protected. It's also a good idea to disconnect the power supply to the machine during storage to avoid any potential electrical hazards.

Periodically, the electrical components should be inspected for signs of damage or corrosion. If any issues are detected, they should be addressed immediately to prevent further damage.

Special Considerations for Different Types of Machines

There are different types of large injection molding machines, each with its own unique storage requirements.

Semi Auto Plastic Injection Molding Machine

Semi - auto plastic injection molding machines have a combination of manual and automatic operations. These machines often have more exposed components compared to fully automatic machines. When storing a semi - auto plastic injection molding machine, extra care should be taken to protect the manual control panels and the areas where operators interact with the machine.

Bottle Injection Molding Machine

Bottle injection molding machines are designed specifically for producing plastic bottles. They may have specialized molds and injection systems. The molds should be carefully stored to prevent damage to the cavities and cores. Additionally, the injection system may require special cleaning and maintenance procedures before storage to prevent clogging.

Conclusion

Proper storage of large injection molding machines is essential for maintaining their performance and longevity. By considering environmental conditions, space requirements, protection from physical damage, and maintenance during storage, you can ensure that your machine remains in good working condition even when it's not in use.
