In the manufacturing of modern electronic and electro-mechanical devices, unexpected failures such as Charging Overheat and Joint Leakage can greatly reduce product reliability and shorten service life. Although these two issues appear to belong to different system domains—thermal management versus sealing integrity—they are in fact closely interrelated. For OEM and ODM manufacturers, understanding this hidden connection is critical to preventing costly after-sales failures and maintaining customer satisfaction. What is Charging Overheat? Charging Overheat occurs when a device's battery or charging circuit generates excessive heat during the charging process. This heat can be the result of design inefficiencies, poor component quality, or misuse by the end-user—such as charging in a high-temperature environment or using incompatible chargers. Excessive heat during charging not only threatens battery safety but also impacts surrounding structural components, especially plastic joints, seals, and adhesives that are sensitive to temperature rise. Understanding Joint Leakage Joint Leakage refers to the loss of sealing effectiveness at the device's assembly seams, gaskets, or bonded areas. Leakage points often allow moisture, dust, or other contaminants to enter the device interior, potentially damaging sensitive electronics or reducing mechanical performance. For devices like electric toothbrushes, grooming appliances, or medical instruments, maintaining watertight or airtight joints…
In the manufacturing of consumer electronics and precision appliances, problems such as Handle Cracking and Connector Corrosion are often underestimated, yet they play a critical role in determining the overall lifespan and reliability of the device. For OEM and ODM partners, understanding how these two failure modes impact product durability is essential to optimizing design, reducing warranty claims, and maintaining market competitiveness. What is Handle Cracking? Handle Cracking refers to the development of visible or internal fractures in the plastic, rubber, or composite material used in the handle of a device. This issue is common in products that are subjected to repeated mechanical stress, exposure to moisture, UV radiation, or temperature cycling. When cracks form in the handle structure, they compromise both the mechanical strength and the sealing capability of the device. Over time, handle cracking can lead to water ingress, contamination of internal components, or a loss of structural integrity—all factors that contribute to premature product failure. The Risks of Connector Corrosion Connector Corrosion occurs when metal contacts in electrical connectors are exposed to moisture, salts, or corrosive environments. This leads to oxidation or material degradation that increases electrical resistance, causes intermittent connections, or even total circuit failure. Connector…
