Powder Systems

Mediprint's Powder system consists of various interlocking components.

Mediprints Powder system

Our powder extraction system prevents contamination of your printed sheets, reduces soiling and wear and tear of the printing machine, and reduces the fine dust pollution in the printing enviroment. An extraction system is indispensable, because with every sheet that is printed there is also some excess powder in the machine. This is extracted by the suction system precisely and efficiently. We offer you the best conditions for an optimal print result for further processing under the highest hygiene standard.

With Mediprint’s Modular Powder & Extraction System (MP&ES), the powder is applied very precisely, with our specially developed modular system concept in order to reduce powder turbulence to a minimum at high printing speeds during the dusting process.

On the one hand, we use our AST, which is manufactured according to your wishes, as a powdering system. The powdering step then takes place within the encapsulated spray chamber and is finally picked up and processed again by our filtered suction system.

The Mediprint suction system reliably loosens powder residues that would otherwise stick to the machine and cleanly removes the loosened dirt without impairing sheet travel. As a result, the printed sheets are kept free of falling clumps and the cleaning cycles as well as the durability of the machine are optimized.

The Mediprint powder system, which is individually tailored to your machine format, ensures precise and economical powder dosing, even with high powder quantities, with minimal machine stress and maximum suction power.

AST
Modular Powder & Extraction System (MP&ES)

The AST is Mediprint’s top device and has been specially designed for continuous use on large printing, packaging, and glass machines. The AST guarantees maximum powdering comfort thanks to sensor-controlled automatic refilling and permanent functionality thanks to two control systems and tube technology. You will experience a new quality of print powder dusting with highly specialized and individualized areas of application. The AST can be used in different versions and including extensions and can thus achieve powdering widths of over 2m.

Security information:
Many types of dust are flammable and can, in conjunction with an ignition source, lead to filter fires and dust explosions in individual cases. Therefore the operator of an extraction system has to take appropriate steps to avoid these specific dangers and especially has to ensure that during operation of the extraction system no ignition sources will be sucked. Additionally he has to meet the ATEX-directives.

Any necessary adjustments to the system have to be agreed prior to the execution in detail, and will be according to expenditure.

System is delivered in a compact metal casing. The regulation occurs by the internal control box. Automatic adaption of powder quantity to the respective speed of web is integrated. Control via speed signal (0-10V) to be provided by customer. Monitoring of min. powder quantity by light barrier sensors and monitoring of air pressure via pressure sensors fixed at the injector. This system enables application of pourable powder with medium-sized particles of 20-30μm.

Unique selling points

In addition to numerous product-specific unique selling points, Mediprint relies on the following features for all of its products:

Isolated cutter head

The hardened cutter head of our tab inserters can be flexibly changed at any time without the need to dismantle the tab inserter

Tape embossing

By adding structure to the stripe its strength is increased requiring less grammage​

Self-counting

With an (optional) sensor, Mediprint tape inserters can count themselves independently of the machine

Multifunctional

Mediprint Tape Inserters can distinguish between different input signals and therefore differentiate between use cases​

Multilingual

The menu offers 3 different languages (ENG, FRA, GER) and can be extended by further languages if required

Aluminum housing

Mediprint deliberately uses aluminum enclosures to weather the heat and dust in packaging and printing machines

The services we provide for you!

SUBSCRIPTION

Mediprint offers selected customers a subscription service on its own products at special conditions. This allows customers to automate the process free of charge and save additional money.

LEASING

Especially for customers whose workload and machine park size fluctuate, we offer individual leasing contracts for our tape inserters in order to streamline their cost structure and at the same time to increase flexibility.

INDIVIDUALISATION

Since most of our products are manufactured in batch sizes <25, individualisation in production can be realised at relatively low cost.
