Where is mechanical active spraying applicable?
Spraying method is the most frequently used coating method in the industry, and is divided into mechanical active spraying and manual spraying.In this, mechanical active spraying is used for a wide range of production, a large number of or durable production of customers.
Advantages are: selectable spraying, high accuracy, average, high efficiency, and can be actively tested.Three anti - paint process of spraying
Errors and fallacies are: high cost, high requirements on the accuracy of the operation, and can occur shadow (the lower part of the components do not cover the place of three anti - paint).
However, manual spraying is usually a combination of hand-held spray gun, air pipe and air compressor (+ exhaust fan).
Advantage is: low cost, suitable for medium-sized customers.Nut punching rod processing but it needs more than 5KG pressure, to form fog barrier, is a higher requirement for air pressure conditioning, if the air pressure is not high, three anti paint does not atomize, will be drawing, manual spraying on the control of precision requirements are also higher than force.
Hand can spraying is also a kind of manual spraying, using spray can products, used for maintenance and small range of production, the greatest advantage is convenience.In a word, manual spraying investment is small, easy to operate;Mechanical active spraying coating divergence is better, the highest yield effectiveness, easy to realize the active production line at the moment, nut punching bar accessories can be suitable for large and medium-sized batch production.Bivariate and material cost generally will be better than the dip coating, is also the need for whitewashing process but not as high as the dip coating requirements.
The error fallacy of response is: requirements whitewashing process;Great waste of materials;Large manpower requirements;Coating bifurcation poor, nut processing plant can have a masking effect, on the narrow spacing above the components into the difficult dimension.
