About the company

For over 30 years, DREWMAX Sp. z o.o. has been developing and implementing modern solutions for the weighing and packaging of bulk products. Our company’s many years of experience in the comprehensive implementation of production lines ensures that our projects guarantee the highest quality at every stage of the production process.

DREWMAX Sp. z o.o. employs a highly qualified team comprising designers, automation engineers, design office engineers, welders, electricians and electrical fitters. We carry out projects comprehensively — from preparing the construction design and developing a customised process design, through the manufacture of machinery, support structures, control cabinets, and electrical and pneumatic installations, to the creation of an integrated control system covering all equipment comprising the production line.

Manufacturers who have placed their trust in us can count on round-the-clock service support. We provide not only mechanical repairs, but above all remote support from automation engineers, enabling immediate diagnosis and rapid problem resolution. This ensures the continuity of production line operations and minimises any downtime.

Packaging in 5–50 kg units

One of the key areas of DREWMAX Sp. z o.o.’s operations is the automation of the packaging process for bulk products. Our weighing and packaging machines ensure smooth and precise dosing of the packaged products.

Weighing and packaging lines

Our lines are designed for packing products into multi-layer paper bags with gusseted bottoms, and polyethylene bags (pre-made and FFS). We offer both semi-automatic lines (with manual bag feeding) and fully automatic lines, in which the machine independently retrieves empty bags from a hopper.

The sealing process is automatic and ensures a tight seal, even with very fine materials, thanks to the use of a double-fold system for the top edge of the bag before sealing, or the sealing of a foil insert in multi-layer bags.

Weight control and labelling

In response to requirements regarding packaged materials, we integrate checkweighers into the lines, which weigh each bag as it moves along the conveyor belt. Bags outside the specified weight range are automatically rejected.

Additionally, the lines can be equipped with label applicators with printers, enabling labels to be applied to both empty and full bags. This solution allows information to be printed onto a pre-prepared label and automatically applied to the bag that has passed the weight check.

Palletising and securing pallets

Our range also includes palletisers that enable the even, stable and aesthetically pleasing stacking of bags on a pallet. The machine automatically retrieves pallets and spacers from built-in magazines.

The greatest advantage of palletisers is the stable formation of layers thanks to the use of several types of clamps, which prevents the bags from shifting and the formation of the so-called ‘Christmas tree’ effect. Once palletising is complete, the pallet is automatically transferred to a wrapper or hooding machine, and can then be labelled.

Process automation and efficiency

The greatest advantage of our fully automatic lines is the complete automation of the packaging process, based on a single integrated control system.

The operators’ role is limited to replenishing empty bags, thread, label rolls, pallets, spacers and stretch film. The minimal operational requirements allow for a throughput of up to 800 bags per hour.

Packaging in Big-Bags

Another area of DREWMAX Sp. z o.o.’s operations is the design and manufacture of machines for packaging bulk materials in Big-Bags. As a manufacturer of industrial machinery, we can adapt our solutions to the existing layout and current machinery of the plant. In the seed industry, the ability to pack seed into Big-Bags is particularly important, which is why we offer flexible line configurations tailored to our customers’ actual needs.

Alternating operation of the Big-Bag packing line with the weighing and packing line

By adapting to the existing machinery in the production hall, we can position two of our packing lines under a single feed conveyor and select the product route using a two-way diverter. This solution enables both machines to operate alternately.

A buffer hopper or an additional diverter can be installed above the Big-Bag filling line, allowing for the configuration of an additional Big-Bag filling line operating alternately with the first.

Automated Big-Bag filling stations

If high Big-Bag packaging throughput is required, the Big-Bag line can be equipped with a buffer tank, a load cell tank scale (net weighing), an automatic pallet and divider magazine, and a roller conveyor system. The Big-Bag station is additionally equipped with a semi-automatic spout onto which the Big-Bag apron is suspended, automatic slings and a Big-Bag inflation system.

Integrated control system

The control system, developed by our industrial automation specialists, is another element ensuring that the production line achieves its target operating parameters. In our lines, we integrate equipment supplied by other manufacturers, including granulators, mixers, mills, feeders and other devices that do not have their own control systems. All equipment forming part of the installations we deliver communicates with one another via a single common control system. The equipment is connected via an industrial communication protocol, which enhances operational reliability and facilitates diagnostics in the event of a fault.
