Manual flame treatment is the economical solution for surface activation of small batches. In addition, the method is also suitable for determining the optimum treatment duration of new substrates in trials. This ensures optimum results in subsequent large-scale production.
The FTM device is preferably used for the treatment of plastic and metal moulded parts, but sheets and films can also be treated. In addition to the treatment of small batches, the device is also very well suited for trial, standby and repair operations.
The manual flame treatment device consists of a mobile, combined pneumatic and electrical housing, from which a 3-m-long hose leads to the burner. The burner is lightweight and has a piezoelectric ignition in the handle.
The standard treatment width for manual flame treatment is 100 mm. For the treatment of grooves, we also offer a special round burner with a narrow and longer flame.
The air supply to the flame treatment system is provided by a built-in fan, which allows stepless adjustment of the flame output. All signal lights for the operating states and buttons for power adjustment are located on the clear control panel on the front of the housing. A shelf for the burner and a balancer for hose fixing are available on request.
Polymers, metals and other substrates have poor wettability when untreated. The aim of surface treatment for plastics and other substrates is therefore to increase the surface tension in order to improve the adhesion of the surface. This can be done using chemical primers or waste-free using physical processes.
Flame treatment is a physical pre-treatment process. The surface is activated by a specially adjusted flame in which unused oxygen and combustion products, such as CO₂ or H₂O molecules, are partly present in activated form and thus form free radicals (such as O or OH). These are extremely reactive and are thus able to break up the non-polar molecular chains on the substrate surface or remove residues of impurities (precision cleaning).
This results in a polar and clean surface that is very well suited for binding with paint, varnish or adhesive molecules. Flame treatment is generally suitable for activating all types of substrates that can also be activated with a corona or plasma system; i.e. polymers, metals, ceramics and glas. For an optimal result, the parameters of the flame plasma must be selected correctly. For this purpose, these are either determined by means of sample tests or derived on the basis of our experience with similar solutions.
Manual flame treatment differs from surface activation with other flame treatment systems only in that the burner has to be guided manually. Particular attention must be paid to the fact that the substrate is only processed with the non-luminous part of the flame. The blue flame areas must not touch the substrate.
Propane or natural gas are generally used as fuel gases to generate the flame. The flame intensity is adjusted by a single control knob. When used as intended, manual flame treatment does not produce any gases that are harmful to health.
Manual flame treatment systems such as our FTM device are typically used in the pre-treatment of small batches. In large-scale production, an in-line flame treatment system is usually the more sensible solution. However, manual flame treatment can be a valuable back-up option if the actual system needs to be serviced or repaired.
A manual flame treatment system also provides valuable services in the laboratory in order to test the optimum flame parameters such as mixing ratio, performance and speed of new substrates. This allows the optimum parameters for surface activation of a material to be determined before it is activated as part of series production.
