Gema Magic Plus Paint Application Booth

Gema's Magic Systems offer a complete solution for all your color change needs.

This simple and efficient design can be adapted to every user's needs in terms of manual pre/post touch-up, number of guns, object dimensions.

Magic Systems remain clean during operation: the non-conductive plastic walls and the self-cleaning floor prevent powder accumulations. Traditional sheet metal booth walls are conductive and attract charged powder particles that accumulate in thick layers on their surface.  Magic Systems’ plastic sandwich walls are non-conductive and do not attract powder. Only a small amount of powder particles can deposit on the nonconductive walls. The charge of the deposited particles create an electric field that repels powder.

Air-knives are integrated in the side-walls of the Magic Systems’ floor. During operation and cleaning air blasts are periodically released by the air knives. The air blasts remove the powder accumulated on the booth floor and push it to the extraction and recovery system. The booth floor remains clean, with just a minimum amount of powder

Magic Systems have very low powder accumulation, therefore the operator can clean the walls and the floor easily and quickly with an air lance. The risks to blow powder out of the booth and to contaminate the ambient are minimised. The risk of colour contamination due to improper booth cleaning is also minimised. Colour change is easy, quick and contamination-free.

In Magic Systems the overspray powder does not accumulate in thick layers on the walls and on the floor. The overspray powder is immediately recovered and reused. The mix of fresh powder and recovered powder remains constant over time. This results in significant improvements of the application quality.

Magic Systems have only a minimum powder accumulation inside the booth. At colour change the operator does not need to remove thick layers of powder accumulated inside the booth. The operator’s health is much better protected. The risk of powder escaping and contaminating the ambient is minimised.

Operation

The dust-laden air flows into the side of the filter housing . The perforated baffle plate in the inlet region assures a uniform flow distribution and enables coarse particles to be pre-separated. As it flows through the cartridge, fine dust is separated on the surface. The filter cake is cleaned off at fixed intervals, depending on the dust load and the filter surface load.

The detached dust drops down through the hopper and is collected in the bucket. The cleaned air flows into the clean air section and is discharged via the blow-out grid. The fully automatic compressed air cleaning system comprises a pressure vessel with membrane valves, an electronic ∆ p controller and the cleaning units.

More powder on the parts, less in the recovery

The powerful 100 kV cascade and the advanced electrostatic controls ensure the highest transfer efficiency even with challenging powder

PCC technology and SuperCorona improve quality

Improve penetration, reduce orange peel, backionization and picture frames even with difficult powders.

Today’s powder coaters need to use a wide variety of powders, with different formulations and characteristics. Only the ideal charging of each powder ensures perfect coating results. Gema is offering innovative technologies to achieve the ideal charging of even challenging powders like structured and metallic powders, porcelain enamel, 2-coats 1-fire powders, etc.

In a corona gun the high voltage electrode generates a big quantity of air ions. Only part of the air ions really charge the powder particles, the other ions remain free and are attracted by the surface to coat (which is grounded). The accumulation of free ions on the surface to coat can produce an uneven powder layer and the so called “orange peel effect” or “back-ionization” problems.

Most powders need the gun to deliver a high level of charging current in the region of 10 to 100 µA.  Special powders (metallic, enamel, two coat / one fire powders) are high-chargeable and require the guns to deliver a lower and well controlled charging current, below 10 µA. The precise charging PCC technology or the SuperCorona add-on are the ideal solution to provide the right amount of charges needed by each powder type This results in a much more efficient charging process and improved application quality.

Traditional Charging:  In traditional corona guns the regulations of the electrostatic parameters are not very precise. The actual value of the charging current can vary within a significant range in comparison to the set value. As a consequence the parameters can be set only with a relatively large resolution (1 µA / 1 kV or more)

Orange peel effect and back-ionization can happen when the guns are emitting too much charges. These charges accumulate on the surface to coat and create visual defects. PCC technology and SuperCorona help to optimise the amount of charges that are needed by each powder. 

Advantages:

  • much nicer surfaces,
  • even with special powders, even when high film thicknesses are needed

Precise Charge Control (PCC): more precise, high resolution Gema has developed PCC, an electronic technology that allows more precise electrostatic regulations. The electrostatic parameters are kept within a much smaller variation band in comparison to the set values The parameters can be set with a smaller resolution (0.5 µA) and controlled much more precisely.

Precise Charge Control (PCC) mode is automatically activated when Current is set below 10 μA. The OptiSpray display showing the High Voltage and Current control turns red when PCC mode activates.

Powder penetration: Powder penetration into corners is difficult because of the Faraday Cage effect. The electric field (created by the electrode and by the charges) pushes powder particles to the edges of the object, while the electric field is not getting into the corners. PCC technology and SuperCorona reduce the electric field generated by the free ions. 

Advantages:

  • Easier penetration into corners
  • More regular powder distribution
  • Powder savings

The PZ Powder center with Gematic control unit is conceived for simple and clean handling of the coating powder and enables a quick color change.

The coating powder can optionally be processed either from powder containers, as delivered from the powder manufacturer, or from a special fluidised container. The powder center is an essential part of the colour change system and is largely responsible for the end product quality.

The PZ powder center is an independently functioning unit with its own powder preparation unit, powder transport equipment with blow-off equipment, an exhaust air system, an electrical control unit and pneumatic control unit.

The powder center is designed for a quick colour change concept and replaces the usual powder coating from fluidised powder containers. Instead of fluidised powder containers, powder boxes or powder manufacturer's containers are supplied for direct use. After using, these containers can be kept in the powder storage room.

In order to avoid colour change problems, well known from practical experience, a fundamental difference is made in the powder center between light and dark colours, to achieve a quick and qualitatively good changeover from light to dark colours or vice versa. This means, that an own set of powder hoses for light and dark colours is provided.

Powder preparation unit

In the powder preparation unit the recovered powder and also the fresh powder are prepared for the transport to the spray guns. The powder box or the powder container, from which the guns are supplied, is positioned on the vibrating table. An additional, local fluidisation enables the powder transport.

Powder transport equipment

In this collective term, the injectors with the suction tubes, the powder hoses and powder level regulation with fluidisation are included. The complete powder transport equipment is fitted on a pneumatic linear cylinder.

Blow-off equipment

The blow-off equipment enables the automatically cleaning or blowing off of the injector suction tubes, injectors, powder hoses and spray guns. The blow-off nozzles required for this, are fitted below the vibration table. One blow-off nozzle is required for each injector. The cleaning procedure must be initiated manually by activating the cleaning key on the powder center. Starting from this time, the cleaning procedure takes place automatically.

Cleaning operation

The booth is stopped on the booth control unit, switched to cleaning operation and the booth doors are closed. The powder container or powder box are removed from the powder center. Now, the activation of the cleaning function can take place on the powder center. The powder transport equipment moves down into the cleaning position.

The injector suction tubes, the injectors, the powder hoses and the guns are rinsed in pulses with compressed air. During the cleaning sequence, the powder transport equipment is cleaned manually on the exterior with a compressed air gun. Detailed information about the commands mentioned in this manual you will find in the Gematic control unit operating manual.

As a part of the process controlled coating plant, it is laid out for fully automatic operation. The most important characteristics of the powder center are: -

  • Processing powder from the original container or from the fluidised container
  • Functional unit with its own exhaust system
  • Integrated electrical and pneumatic control units
  • Powder level monitoring through level sensor
  • Level controlled raising and lowering station with built-in injectors and fluidizing equipment
  • Automatic internal cleaning of the suction tubes, injectors, powder hoses and guns
  • Return of the recovered powder through a sieve machine or directly into the powder container
  • A built-in exhaust unit prevents the escape of powder particles during the coating process and during cleaning

General operating sequence
Powder flow With the typical operation of the powder center, the powder container is placed on the vibration table. The injectors move downwards into the powder through the level sensor, and fluidise the area around the suction tubes.
The fluidised powder is sucked up by the injectors and fed through the powder hoses to the spray nozzles. The powder, which does not adhere to the workpieces, is absorbed by the exhaust air of the booth and separated from the air in the cyclone separator.
The separated powder is cleaned passing through the integrated sieve and transported back into the powder container by the dense phase conveyor  where it can be reused for coating operation.

Gema PS5 Powder Sieve.

A good sieving solution helps to eliminate contamination from the recovery circuit and prepares powder ideally for the feed to the guns.

The Gema P5 is a swing aside sieve located at the base of the cyclone, the swing aside action makes cleaning the screen or changing the size very simle. Once placed back in position pneumatic rams tightly seal the mating faces for leak free operation.

Powder passes through a screen and retains particles with a larger diameters (contaminants). The choice of the right mesh size of the sieving screen is very important and usually requires some compromise, a finer mesh grants a higher-quality sieving, a bigger mesh allows larger powder throughput.  Vibratory sieves are the easier solution, robust and reliable.

Details

  • Available mesh sizes 300 - 500 µm
  • Powder sieve capacity on standard mesh size & depending powder up to 3 kg/min
