How To Drive Screws in a Clean Manufacturing Environment

The DEPRAG CleanFeed system is the world’s most comprehensive solution for technical cleanliness. From the initial engineering design to the assembly environment, DEPRAG CleanFeed utilizes decades of process knowledge, solutions, specific developed components and a thorough understanding of the production and assembly steps, to create the ultimate technical cleanliness solution.

The DEPRAG CleanFeed system begins by defining the cleanliness requirements for the client’s product. Then, in cooperation with the client’s quality department, design engineers, production and logistics, a solution is created to achieve the highest level of technical cleanliness and reliability.

Training the staff is just as important as a clean production environment. The production environment should be maintained in a state of meticulous cleanliness to prevent disruptive particles from being introduced by humans, materials or transport systems.

Already at the components design stage it is possible to avoid scenarios where particles could collect by choosing suitable materials, such as polished stainless steel or anodized aluminum surfaces.

With standard vibratory feeders the screws rub against one another and harmful particles are created by the abrasion. With the right technology the number of particles can be reduced as the fasteners are separated from one another. Sword feeders are used when a non-abrasive feeder is required in order to protect the components. The DEPRAG Sword Feeder uses vertical manufacturing, hardened, wear-resistant materials, and special coatings to ensure consistent high levels of quality, reliability and efficiency.

The DEPRAG Particle Killer adds an additional layer of protection to the feeder system by using a blast of air to shoot the screw into position. Any particles that may be created during this process are removed by vacuum suction.

The DEPRAG MINIMAT®EC-Servo range of screwdrivers reduce their speed as they engage with the screw. The on board sensor system assists with recognizing the precise position of the screwdriver and ensures that the bit engages properly into the screw drive. Once the bit is correctly engaged into the drive, the speed increases to carry out the tightening action. This reduces the amount of harmful abrasions while vacuums extract any remaining particles.

DEPRAG screwdriver function modules are compact and can be used for inverted fastenings, using gravity to drop particles away from the product.

Because DEPRAG is the single source supplier, all the components work in harmony with each other.
