We all know that whether using a conventional electric screwdriver or an automatic screw locking machine, it is common to encounter situations where the torque reaches the preset target torque and stops, but the screw is not fully tightened. This is often referred to as screw floating, also known as "floating high" or "floating nail." So why do screws float? Generally, t...
Torque overshoot—when the actual torque exceeds the preset or target value—can cause serious problems: Bolt Damage: Exceeding the bolt’s torque limit causes plastic deformation or even fracture. This not only ruins the bolt but can trigger a chain reaction, degrading overall system performance. Loosening of Joints: Excessive torque increases internal stress, leading to...
Blow-type screw feeders play an important role in industrial automation. The maximum screw size they can handle is a key performance indicator. However, since there are many different models and specifications on the market, the maximum screw size varies. So, what is the largest screw a blow-type feeder can handle? Let’s take Danikor’s blow-type screw feeder as an exampl...
Due to their extended length and specific design, long screws are widely used in mechanical equipment, the automotive industry, electronic devices, aerospace, and other fields.

In 3C electronics assembly, huge numbers of micro-screws (M0.5–M2) are used. Their tiny size makes traditional manual picking slow, prone to dropping screws into the product or losing them altogether. Common vibratory bowl feeders often jam, wasting cycle time and reducing throughput. Danikor’s rotary-disk (water-wheel) automatic feeder solves these problems: Vacuum pi...
Turbo-chargers are key components in automotive, aerospace and defense applications. A typical unit is built from a rotor, compressor, sealing set, center housing and bearing system.
