Since more than 10 years GEFRA offers a real 360° surround inspection with 4 cameras to inspect the surface of round parts to find coating defects, head cracks and external thread damage. One of the big advantages of the GEFRA system is that the parts run continuously with a speed up to 600 parts per minute.
This system can be used on a glass dial machine with standing parts as well on the slot dial machine with parts hanging in the disc.

GEFRA – Made in Germany
Since 1995, the GEFRA Company is developing and manufacturing inspection systems for automotive and aircraft fasteners and other bulk products.
GEFRA OPTISORT systems ensure an efficient 100 percent automatic quality control where a cost efficient and zero ppm error quote is needed.
More than 280 systems all over the world are speaking in the GEFRA Company’s favor.

360° Defect Detection
The thread inspection was getting much more important during the last three years for most of the manufacturer of automotive and aircraft fasteners.
That`s the reason why most of the GEFRA`s inspection systems had the additional 4 cameras inside.
The 360° inspection system is very flexible and can be used for head cracks from the side, thread inspection on different length and also for bended parts. The position in the hight of the cameras can moved depending on the areas which are to be inspected.

Easy to use
The approved PC-based system software AUTOCONTROL made by GEFRA itself does the image processing and generates the IO/NIO decision with the help of an individual quality control plane, which includes all important parameters of the part.
While the program is running, it is possible to save the pictures of the checked threads. If you want to see the damages, you can recall the images from the computer-storage. With these pictures the operator can compare the checked parts with the calibration part. The picture of the calibration part is able to call up while the operator is adjusting. So he can compare between the good and the actuell part.

All in one's
The GEFRA product portfolio is complemented by a wide spectrum of offers in the fields of accessories also for packaging, service, maintenance and training.
A high availability of spare parts and a short reaction time to all cases around a sorting system is guaranteed by the GEFRA team.
So the GEFRA Company is a reliable partner for all-in-one’s quality applications in the field of fastener manufacturing.
