This flexible pad adapts to curved and textured shapes, making it an excellent…
When an electric toothbrush experiences a vibration malfunction, the handle can produce excessive or erratic amplitudes that not only compromise cleaning but, over time, may trigger gum recession. To help B2B manufacturers understand this critical risk, we analyze six key dimensions and provide actionable design and support strategies. How Vibration Malfunctions Damage Periodontal Tissue First, abnormal vibration patterns harm gums through: Excessive Instant Amplitude: Sudden high-amplitude jolts tear the fibers attaching the gum to the tooth neck. Frequency Instability: Rapid frequency shifts create micro-tears in the gingival tissue that accumulate into recession. Resonance Amplification: If the motor frequency resonates with the handle’s structure, localized motion spikes, worsening the impact. Understanding these mechanisms enables targeted improvements to vibration control. User Habits That Amplify the Risk Next, brushing behaviors can magnify the harm from malfunctions: Increased Brushing Force: Users often press harder to compensate for lost cleaning power, further stressing the gums. Prolonged Dwell Time: Lingering on one area subjects the same gum region to repeated impacts. Frequent Mode Switching: Repeatedly toggling modes can trigger more erratic vibrations, intensifying tissue damage. Guiding users on correct grip and brushing motion is therefore essential. Common Design Flaws Leading to Vibration Malfunction Furthermore, these design…
In today’s competitive oral care market, Electric toothbrush laser engraving is more than just decoration—it’s a core part of brand identity and consumer recognition. For electric toothbrush factories, offering toothbrush laser engraving customization adds value, enhances brand consistency, and ensures that the logo remains clear and durable throughout the product’s lifecycle. Laser engraving, as a permanent LOGO process, is widely favored because it doesn't fade, peel, or wear off like ink printing. But achieving high-quality engraving depends heavily on fine-tuning the right parameters: depth, speed, and power. Understanding the Basics of Laser Engraving Parameters To achieve precise and durable results, manufacturers must control three key laser engraving parameters: Power (W): Determines how much energy is delivered to the surface. Higher power increases depth but may burn or deform soft plastics. Speed (mm/s): Dictates how fast the laser moves. Faster speeds result in lighter engravings; slower speeds go deeper but may overheat the material. Depth (mm): Not a directly set parameter, but the result of how power and speed interact. For toothbrush handles (usually ABS or PP), ideal depth is 0.1–0.3 mm. Proper tuning ensures the OEM brand logo looks sharp, professional, and permanent on every unit. Material Consideration: Matching Settings to Handle Composition Electric…

When users complain of whitening unevenness, many manufacturers focus solely on bleaching formulations and overlook how improper frequency settings can lead to motor overheating and undermine product durability. In fact, incorrect vibration frequencies not only reduce activation efficiency but also accelerate enamel fatigue in localized areas, resulting in uneven whitening and increased wear. The Link Between Frequency Settings and Whitening Uniformity First, the frequency of cold-light or sonic activation directly dictates the speed and depth of free-radical generation: Low-Frequency Modes (<20 kHz) lack sufficient energy to break down deeper stains, causing superficial whitening. High-Frequency Modes (>30 kHz) improve penetration but concentrate energy and risk over-oxidation “hot spots.” Frequency Fluctuations: Without proper firmware compensation for voltage drops, load-dependent frequency jumps amplify whitening unevenness. Achieving precise and stable frequency output is therefore fundamental to consistent whitening. How Improper Frequencies Stress Enamel Next, mismatched frequencies impose cyclic stresses on the enamel surface: Micro-fatigue: High-frequency oscillations propagate micro-cracks, diminishing enamel hardness. Chemical-Mechanical Synergy: Vibration accelerates peroxide erosion, increasing surface porosity where stains can re-adhere. Localized Overheating: Excessive frequency settings can lead to motor overheating, transferring heat to tooth surfaces and intensifying chemical attack. Altogether, improper frequency settings are a key driver of both enamel…
