Deburring is considered a light finishing operation, since it removes burrs, the residuals of material, usually of small dimensions, that remain on the surface of the article and along its borders, after the operation it underwent. The presence of small or big residual material has a negative impact on the surface quality and aesthetic quality of the article.

Since thermoplastics have a low thermial conductivity, the tooling operations that produce the highest quantity of burrs are those that heat up the article locally, that’s to say milling, drilling with removal of the chips and cutting with saw. The thermoplastics that produce the highest amount of burrs are the softest ones. The hardest thermoplastics, such as those reinforced with glass fibre, are more resilient to heat and produce a reduced amount of burrs.

The machineries of GS Finishing Machines can carry out the following kinds of deburring.



Burrs are removed manually or automatically by means of a specific tool. It is the most common method, since it is flexible and allows a last visual check of the article.



When heated up by a blow of hot-air, burrs melt down and shrink, adhering to the surface of the article. It is a safe method, since it allows to easily check the air temperature, so as to avoid that the heat damages the article.


The articles that we can deburr are produced by means of injection moulding, extrusion moulding, compression moulding, thermoforming, blow moulding, suction 2D/3D (2k) and rotational moulding.

Among the articles deburred by the customized machines of GS Finishing Machines there are the following, listed as an example: doors of glove-compartment, control dashboard of trucks, ends of engine dirty-air and clean air pipes, ends of fuel filling pipes, ends of pipes for the air conditioning of the inner compartment, ends of filling pipes for windscreen wiper’s liquid, tanks for various automotive liquids.
