4th of July Holiday

DEPRAG is closed for the 4th of July holiday on Monday, July 4th, 2016. We will return on Tuesday, July 5th, 2016.


DEPRAG has launched a revolutionary Flow-Form Assembly System, the ADAPTIVE-DFS®, which has features that takes this system to a whole new level. Watch your calendar and see what we have done!

Lose that Feedhose - A Unique Way to Assemble Flow-Form Screws

A feedhose can interfere with the rather rapid movement requirement of a robot, which in turn can cause production interruptions as well as quality issues. DEPRAG now offers a clever solution to this problem.

DEPRAG introduces the revamped Minimat-ED

This handy all-rounder (MINIMAT®-ED) can be quickly and simply adapted to any screw joint. The torque required for the fastener assembly is set directly on the screwdriver at the push of a button. Up to five programs (with pre-defined torque or angle values) can be saved and selected as needed.

Flow-Form Automation by DEPRAG


In assembly areas where access from both sides is not possible, an alternative fastening process is required. In such cases, screw tightening made with flow drilling screws have come to the forefront as a solution to the problem. Flow drilling screws create a high-strength fastener connection and form a process-reliable joint for different types of sheet metals. 

                                                                             Flow-Drill Process
One Cycle incorporates the following processing steps:

  Step 1: Heating

  Step 2: Penetrating

  Step 3: Funnel Forming

  Step 4: Thread Forming

  Step 5: Screwdriving

  Step 6: Final Tightening



The new DEPRAG system is recommended because of its ability to adjust flexibly in places where available space is at a minimum. For those applications, robotic screwdrivers are designed to specifically deal with limited space situations. By using a 1:1 ratio offset gear to offset the drive motor and screwdriving axis to the side, the DEPRAG "FFS" screwdriving system can access screw positions located as little as 10-millimeters (0.393 inches) away from an obstacle! The screwdriving module can be turned in any direction, and simplifies the deployment into any position. It is available with a single configuration with Top-Rear-Left-Right robot mounting capability.

It incorporates an adjustable force from 150 - 3,000 N (34 - 674 pound force). This automation system utilizes already established product lines such as the proven MINIMAT-EC screwdrivers, DEPRAG feeding equipment, as well as its controllers that have proven themselves many times over.
