About us

AZO provides innovative bulk material handling, raw material handling, pneumatic conveying systems, mixer feeding, screeners & bulk containers for the reliable automation of production processes for the industry in foodstuff, pharmaceutical, chemical and plastic.

In the plastics industry our customers are: PVC dry blend manufacturers and companies within the extrusion sector, Manufacturers of plastic compounds with surface improvement Companies within the PVC paste processing sector Additive and master batch manufacturers and plastic processing companies

AZO transports raw materials such as plastic powders, chalk, titanium dioxide, modifiers, additives, plasticisers, paints, pigments, stabilisers, fluids, granulates and masterbatch fully automatically to mixers, extruders, compounders, granulating and dispersing systems, coating units, blown film extrusion lines right up to injection moulding machines and compactors. Future-proof process engineering and innovative process technology coupled with trend-setting process IT ensure the highest standard of quality in profiles, pipes, slabs, films, compounds, floor coverings, wall coverings and synthetic wallpapers as well as plastic additives, plastic films, technical plastic components, hollow bodies, glass components and spunbond web

We plan, produce and install machines and systems all over the world for storing, discharging, screening, conveying, dosing and weighing bulk goods, powder components, flavourings, additives, ultra-low quantities or fluids. Our systems make sure that all recipe components reach the correct processing operation at the right time and in the right quantity.

The AZO Group of companies with its headquarters in Osterburken, Germany, is a family firm now managed in the third generation. Our customers benefit from the high quality and reliability of our solutions as well as on more than 65 years of experience in automatic material supply.

Time and time again, we look for the best solution for our customers from the drawing board, therefore we are now one of the world's leading companies when it comes to automatic handling of bulk goods and liquids.

Feeding of mixers with vacuum weighing systems
Besides the major component PVC all raw materials except titanium dioxide and micro-ingredients are fed into the heating-cooling mixer by means of the vacuum conveying scale. While PVC and filler materials are dosed into the conveying line and are weighed precisely in the conveying scale, the other components have their own scales in which product batches can be pre-weighed. These other components then also pass through the single-pipe system to the conveying scale. This concept achieves a high level of dosing and weighing accuracy while at the same time achieving flexibility in the delivery of raw materials coupled with low building height.

The handling of titanium dioxide
With the help of a separate vacuum conveying system, TiO2 is conveyed into a buffer bin above the heating-cooling mixer from which it is dosed into a scale through a dosing screw. This scale empties directly into the mixer. This separate scale makes it possible to add TiO2 at a later point in time because its abrasiveness can cause severe wear to the mixer tool and to the bottom of the mixer. TiO2 is so fine that it has high adhesion properties. It therefore has a tendency to clog and block rigid pipework. To counteract this, special flexible conveying lines have been installed. The TiO2 sticks to these less and the flexibility of the line also makes it easier to release again.

Supply of additives using ManDos: secure, operator-guided and fully documented

Supply of additives using ManDos: secure, operator-guided and fully documented

Special supply of additives
Using the ManDos manual weighing station, mixing vessels can be filled with previously weighed quantities with little generation of dust. The controls do guide the machine operator reliably through the weighing process. It is possible to add entire bags, but also to weigh micro quantities using platform scales and then add them to the mixing vessel. Errors in production are avoided as the computer prompts operators through the weighing process. Production is documented simultaneously, enabling batch tracing. This cuts down losses or wasted batches of ingredients.

Vacuum conveying systems for feeding the dosing systems.

Vacuum conveying systems for feeding the dosing systems.

With pneumatic feeding systems, personnel costs can be reduced and production buildings designed at lower cost. In addition, one product input station can be used to supply several compounding lines at the same time.

Depending on throughput, pneumatic conveying systems can be operated as a collective feeding system with the help of several separators and a pump. All separators from AZO are equipped with self-cleaning filters. If required, they can also be provided with highly efficient delivery and dosing elements. When working with raw materials with poor flow characteristics and large buffer tanks, the reliable vibration discharger in conjunction with a dosing device is a recommended solution for feeding the dosing systems.
