Unloading and Assembly of Plastic Injection Molding Machine in Łódź

The Strategic Process of Unloading and Assembling a Plastic Injection Molding Machine

In the world of industrial machinery, the unloading and assembly of a plastic injection molding machine represent a significant logistical challenge that requires precision, expertise, and the right equipment. This article delves into the step-by-step process our team undertook to unload and assemble a plastic injection molding machine, detailing the challenges encountered and the solutions implemented to ensure a successful operation.

Step One: Unloading the Injection Molding Machine

The initial phase of the project involved the careful unloading of the injection, closing, and robot parts of the machine. The heaviest component tipped the scales at 32 tons, presenting not just a challenge in weight but also in the spatial limitations of the site. The elements had to be maneuvered over the entrance gate, a task that demanded both precision and power.

To address this, we deployed a 100-ton hydraulic crane, a choice that provided us with a capacity buffer to ensure the safety of the load during lifting. The crane's robust power and the expertise of a qualified crane operator allowed us to deliver the machine components directly to the entrance doors of the hall. This strategic move saved valuable time and reduced the complexity of the operation, as it minimized the distance the machine parts had to be transported on rollers.

Step Two: Transporting the Injection Molding Machine Inside the Hall

Once inside the hall, the heaviest element was carefully placed on a set of transport rollers designed to handle its weight and facilitate smooth movement to the installation site. A 5-ton forklift provided the necessary traction, proving to be an essential asset in the internal transport process.

The closing element was the first to be positioned and stabilized. Following this, the injection part was introduced. This component posed a greater challenge due to its larger dimensions and the confined space within the hall. It required several hours of meticulous work to ensure its safe and precise placement.

Step Three: Assembling All Elements of the Injection Molding Machine

The culmination of the project was the assembly of the machine. This stage involved the precise joining of the two main parts of the injection molding machine using mounting screws. Additionally, the supporting robot was installed in its designated position.

Our technicians played a crucial role in this phase, ensuring that all elements were not only assembled but also perfectly leveled. The final handover to the customer marked the successful completion of the assembly process, with the machine ready for operation.

Machinery and Equipment Utilized

Throughout the project, several pieces of machinery and equipment were instrumental in the completion of the order:

  • Hydraulic Crane: The 100-ton hydraulic crane was pivotal for the unloading process. Its substantial lifting capacity allowed for the safe maneuvering of the machine's heavy components.

  • Suspensions and Hooks: Used in conjunction with the hydraulic crane, these tools ensured the secure attachment and lifting of the machine parts.

  • Forklift: The 5-ton forklift's role was crucial for the internal transportation of the machine elements, providing the necessary power and control.

  • Set of Conveyor Rollers: These facilitated the smooth movement of the heavy components within the hall, proving essential for the precise placement of the machine parts.

  • Hydraulic Power: This was the driving force behind the operation of the hydraulic crane, enabling controlled and steady lifting.


The unloading and assembly of a plastic injection molding machine are complex processes that require a well-orchestrated approach. By leveraging a combination of high-capacity machinery, skilled operators, and strategic planning, we were able to overcome the challenges of limited space and heavy components. This project not only demonstrated our team's capability in handling industrial machinery but also reinforced the importance of preparation and the right equipment in executing such tasks.
