Producing large-scale logistics products like pallets and crates requires a delicate balance of power and precision. For manufacturers serving the global supply chain, efficiency drives profitability. A recent application involving PRONEXT SAS, a forward-thinking manufacturer based in Colombia, highlights how intelligent equipment selection solves the unique hurdles of this sector.
Common Challenges in Logistics Manufacturing
Manufacturing robust logistics containers presents a few distinct challenges on the production floor:
- Mismatched Specifications
Large surface areas demand massive clamping forces to keep the mold securely closed. However, the actual volume of plastic injected is often relatively small compared to the mold size. Standard machine configurations frequently lead to wasted energy and inefficient capital use. - Structural Integrity
Large flat products are highly prone to warping if stress distribution across the machine platen is uneven during the injection and cooling phases. - Operational Safety
Moving massive steel molds at high speeds poses inherent safety risks for operators and increases the wear and tear on the equipment itself.

Strategic Machine Configuration
To address these parameters, PRONEXT SAS deployed a highly specialised configuration. They utilise a JM1000-MK6 clamping unit paired with a smaller 658MK6.6 injection unit.
This specific “small injection, large clamp” setup is an excellent example of matching machinery to application. It provides the robust 1000-tonne clamping force required to hold large pallet molds closed, while the smaller injection unit efficiently manages the exact plastic volume needed. This precise matching conserves energy, optimises the production floor footprint, and ensures superior part quality.
Prioritising Safety Without Sacrificing Output
In the injection molding sector, cycle time is a critical metric. The advanced servo-driven hydraulics of the MK6 system allow this specific PRONEXT SAS configuration to achieve blistering cycle times of 15 to 16 seconds.
However, producing large logistics items involves moving incredibly heavy steel molds. Pushing opening and closing speeds to their absolute mechanical limits introduces unnecessary physical hazards. Recognising this, PRONEXT SAS elected to maintain a highly efficient, yet highly securencycle time.
This decision prioritises worker safety and equipment longevity while maintaining highly competitive output rates. The MK6 machine supports this reliable operation through built-in electrical and hydraulic interlock safety protections, ensuring peace of mind during continuous production.

Technical Highlights Driving Success
The hardware backing this strategy includes several notable engineering advancements that align perfectly with the needs of logistics manufacturers:
-
High-Strength Circular Platen: The MK6 features a platen design that reduces deformation by 25 per cent under equivalent loads. For a company molding large flat items like crates and pallets, this ensures uniform stress distribution and mitigates the risk of product weight variance or deformation due to platen warping.
-
Precision Servo Motor Drive: The sophisticated control algorithms of the servo drive deliver pinpoint accuracy in controlling injection and hold pressure. By reducing the time needed for transitions between processing phases, the system increases overall production efficiency while operating smoothly and quietly.
Optimising an injection molding floor requires looking closely at the actual physical demands of the product line. By customising machine specifications to fit exact production needs and establishing safe operational parameters, manufacturers can achieve sustainable and high-quality output. As the industry advances, intelligent configurations like those utilised by PRONEXT SAS will continue to set the standard for modern manufacturing facilities.
