Some common valve issues that can cause actuator problems: A worn out valve stem. Seized up packing. An obstruction. Too much torque. It doesn’t do any good to repair an actuator when the valve is what’s causing the trouble. On the contrary, it wastes both time and money — and leaves you back where you started.

Common Wirebonding-related Failure Mechanisms: Ball Bond Lifting
The most common cause of motor failure, and arguably the most difficult to overcome, is low resistance. Low resistance is caused by the degradation of the insulation of the windings due to conditions such as overheating, corrosion, or physical damage. This leads to insufficient isolation between the conductors or motor windings, which can cause

Causes: Flow line defects are caused by the varying speed at which the molten plastic flows as it changes direction through the contours and bends inside the mold tool. They also occur when the plastic flows through sections with varying wall thickness, or when the injection speed is too low causing the plastic to solidify at different speeds.

Bearing failure demands immediate attention because it can cost as much as $25,000-$50,000 per hour—in lost productivity, unplanned outages and downtime. What’s interesting, though, is that the bearing replacement itself is almost always the cheapest part of the failure. A $50 bearing can take down a multi-million-dollar process.
