Car Interior Adjustment Ball Products Description
This series of precision plastic balls is specifically designed for automotive interior components such as toggle switches, ball joints, and reset mechanisms. We offer a variety of material options, including POM-H (Delrin), PTFE, and PEEK, aiming to provide global automotive manufacturers with cost-effective and high-performance fluid and mechanical adjustment solutions.
Core technical indicators
1. Ultra high roundness: using centerless grinding technology to ensure consistent resistance when the sphere rotates at $360 O circle
2. Fatigue resistance: Meet the operational cycle life of over 100000 times for automotive interior parts.
3. Low friction coefficient: The friction coefficient U is as low as about 0.1 (depending on the material), without the need to apply lubricating grease, to avoid odors and dust adsorption inside the car.
4. Material grade: The flame retardant grade complies with UL94-HB/V0 and meets the fire protection regulations for interior design of vehicles.
Typical application locations
1. HVAC Vanes: Universal adjustment ball for air guide blades.
2. Interior rearview mirror: base rotating joint supporting ball.
3. Seat adjuster: screw drive or damping positioning ball.
4. Central control button: The positioning ball in the tactile feedback mechanism.
Why choose our adjustable ball?
We are well aware of the almost stringent requirements for batch stability in the automotive industry. Through a fully automatic image detection system, we ensure that every factory adjustment ball has no mold lines, black spots, or size deviations, helping your interior components achieve "zero defect" delivery.
Material recommendation
1. Cost effective first choice: Delrin (POM) - tough to the touch, wear-resistant, suitable for most air vents.
2. High end preferred: PEEK - extremely high temperature resistant, suitable for areas with the most intense direct sunlight such as above the dashboard.
3. Ultimate quietness: PTFE (polytetrafluoroethylene) - although relatively soft, the friction is almost zero.
