Parts made of resin are easily charged with static electricity so dust and other foreign particles often adhere to them. Since panels are exterior parts, there is a strict delivery standard for dust adhesion. Dust must be removed completely before pre-shipment inspection.
Even if the dust is removed with an air blow, it may adhere to the panels again due to the an electrostatic charge.
- Cannot eliminate static electricity, increases the charge instead.
- Cannot remove foreign particles completely.
Countermeasures with static eliminators (ionizers)
Ionized air prevents defective products caused by foreign particles. This measure is taken at the same time as pre-shipment inspection (such as burr inspection). The problem can be solved reliably without increasing takt time.
Disposal cost of $10,000/year + Recall cost (transportation and on-site service travel costs) of $5,000/year = $15,000/year
In addition, the increased level of trust and the solution can be good PR for the company's support system.
