Advantages and Applications of Profile Projectors in Industries


Profile projector primarily used for analysing the shape of the components. Different industries use different type of components. Before incorporating anything, it is important to understand if it is not a misfit in the manufacturing process. The projector helps in measuring the dimensions with great accuracy. Components that cannot be measured using conventional techniques are measured by profile projector. Irregular shapes can be precisely measured with this instrument. 

In PET and preform industry, it is very commonly used. The dimensions of bottles that have irregular shapes can be measured with high precision. This instrument captures the image of the component and then magnifies it to many folds. The magnified images are projected to the operator. 


Advantage of Using Profile Projectors

  • Minute details can be assessed very easily as the images are magnified. Small defects like scratches and burrs also get highlighted. Defect identification can be done very easily.
  • During analysis of the components, there are some indention marks left on the test object. These marks can be easily analysed and identified using this instrument. These might be very minute indentions but can create a considerable effect on the end product. 
  • The profile projectors are used for measuring several measuring at a time which saves time and energy.


Applications of Profile projectors

·         For inspecting components with irregular shapes and sizes. Components which are generally used in different industries need to be analysed first. Not every component can be measured with a micrometre, sometimes due to the delicate nature of the product. Thus, this instrument cut down the challenge of measuring uneven shapes and surfaces.

·         For inspecting shape and sizes of the PET bottles and their defects. There are some defects which cannot be analysed by naked eyes. Moreover, uneven shapes can be measured to bring uniformity into the whole batch.

·         For inspecting surface deformities in the automotive industry. Surfaces of automobiles carry minute defects, like scratches and dents. These defects can be easily magnified using profile projector. 

·         For inspecting minute flaws in glassware. High-end glassware is crafted with precision. Any defect may decrease the mechanical stress and increase the brittleness.


Presto's Profile projector is one of the best testing instruments that offer a projection of high-resolution images of the test specimen for better quality check process. The instrument is equipped with best features that make it the best instrument for use in industries.
