Kaifeng City Bell Stainless Steel Ball Manufacturing Co., Ltd produce high precision adjustment ball assists car interior: defining a new standard for smooth handling and ultimate quietness.
As the global automotive market enters the era of "perceived quality" competition, the operational feel of every tiny component inside the car determines the user's brand impression. Recently, Kaifeng City Bell Stainless Steel Ball Manufacturing Co., Ltd announced that its independently developed precision adjustment ball for automotive interiors has successfully passed the durability test of mainstream Tier 1 suppliers and officially entered the mass production stage.
Core Highlights
1. Eliminating abnormal noise (NVH optimization): In response to the small vibrations and abnormal noises that are easily generated by the air conditioning vents and rearview mirror adjustment mechanisms in the car, [company name] has significantly reduced the fit clearance and eliminated noise caused by looseness by optimizing the roundness of the sphere (tolerance controlled at +/-0.01mm).
2. Smooth texture: using specially modified Delrin Or PEEK material, with excellent self-lubricating properties. When users move the air outlet or adjust the knob, they can feel a "premium touch" with uniform damping, smooth and not dry.
3.Vehicle grade weather resistance: The product undergoes rigorous high and low temperature alternating tests (-40 to 90 C) to ensure that the regulating mechanism does not jam or become brittle under summer exposure or severe winter temperatures.
4.Environmentally friendly and low emission: The materials strictly comply with the VOC (volatile organic compound) emission standards of the automotive industry, ensuring healthy air inside the car.
| Product Name | Bell Balls POM plastic bearing balls (Delrin (Acetal Homopolymer) Balls) DELRIN Balls (ACETAL RESIN-POM) |
| Material | POM Acetal (Polyoxymethylene) |
| Feature | Acetal (POM) is considered a high performance plastic. This particular plastic has excellent chemical resistance, solvent resistance, wear properties and is self lubricating. The natural color of Acetal is white. This material, in its natural state, is heavier than water; meaning it will sink in water. The maximum continuous operating temperature in air for Acetal is 180°F. |
