Prior to coating plastic workpieces, they can be flame heated using a gas burner to improve adherence. This is not a heat treatment but rather a selective utilisation of the chemical effect of the gas flame. Naturally, we also offer further pretreatment equipment, such as the plasma treatment for example. During flame heating, the surface is briefly subjected to the direct effect of a gas flame fed with extra oxygen. This causes the breaking of molecular bonds in the surface of the substrate to be treated, and the binding of active ions, mainly OH and COOH groups existing in the flame. In this manner, polar groups, enabling the secure bonding of printing inks, lacquers/paints, adhesives, etc. are created in the originally nonpolar material. Due to the formation of polar groups, the surface energy of the treated substrate increases to a measurable amount.

Dust removal devices remove adhering dust particles from the workpieces by means of rotating blowing nozzles. The use of ionisation units enables the removal of electro-static charges from the plastic surface, which promote the adhesion of dust. In order to improve operation, the ionisation unit is combined with a dust removal/blow-off device. In the wood sector, this is generally integrated in the line without ionisation unit or installed directly downstream of a brush sanding/denibbing machine. We offer various dust removal/ionisation systems, according to the requirements of your production process. The COMFORT and PERFECT versions are additionally equipped with a rotating genuine hair brush to remove soiling from the surface. We would be please to provide more detailed information concerning the equipment features upon request.

The application of CO 2 ice jet spraying is convincing. Ranging between CO 2 cleaning and high-performance dust removal with regard to quality, optimum pretreatment can be accomplished with this system variant, only requiring simple workpiece fixing and little noise protection measures. DUST FREE can be flexibly integrated in existing equipment. A cleaning jet consisting of a mix of compressed air, CO2 and CO2 ice particles causes the soiling on the surface to become brittle. The thermal tension loosens cohesion and detaches the soiling from the workpiece surface. The cleaning jet guarantees the removal of soiling without residue. The DUST FREE and PERFECT applications optimally meet the requirements of the subsequent downstream surface quality, offering maximum thoroughness from dust removal through to cleaning. This process allows gentle cleaning of virtually all components, therefore, it is an alternative to aqueous power washing. Patented detail solutions form the basis for this mature system technology. Small workpieces are reliably held in place by the special hold-down system. The Venjakob pump station developed for this task guarantees the process reliable supply of liquid CO 2 from a low pressure tank system to the cleaning module. A clear advantage of the CO2 cleaning system over the conventional aqueous cleaning process is its relatively small space requirement. Additional decisive advantages of this system are:

System examples for possible operating widths from 600 to 3,500 and operating lengths from 2,000 to 5,500 mm. Depending on your production requirements, you can individually select from: Short change times and high operating comfort are possible thanks to the quick-exchange brush system using a push-in system together with a coupling. The optional infinite angle setting of the round brushes permits impeccable edge processing. The use of the structured brush unit is intended for special surface processing. This brush is used to structurise furniture parts, hardwood and softwood, flooring boards or to provide an antique look of up to 1 mm deep at a throughfeed speed of 10 m/min. Where required, the VEN BRUSH can be extended by a dust removal system with rotating blow nozzles and ionisation system. Following a brushing or sanding/grinding effect, this complementary function ensures optimum workpiece cleanliness to meet high requirements. As an individual solution, VEN BRUSH convinces as a station in a Venjakob machine line or when integrated in an existing machine line. As such, control system configuration takes all interfaces into account, through to higher ranking control and monitoring. The high-performance system technology can be easily operated directly using a control panel or a touch panel.
