Product details

Our VCM spring is manufactured by chemical etching process. It has high precision, stress-free, burr-free, and no heat effect. Deformation is unlikely to occur due to the etching process. Additionally, the edges of etching do not collapse easily. The benefits of etching cannot be achieved by other processing methods.

Dimensional ToleranceKey Parts (Spring Wire) Dimensional Tolerance Requirements is±10% of the material thickness. Ultra-Thin Materials (<0.05mm) Etching Dimensional Tolerance: ±0.008mm

Material Grade: BF158, GMX215

Thickness: 0.0275mm~0.08mm

Function and Usage: VCM is the abbreviation for Voice Coil Motor. When used on cellphone camera, VCM functions as an automatic focusing mechanism. The key component of VCM is the spring. It supports the lenses and drives the lenses back and forth in order to focus. There are two VCM springs in each camera. By applying magnetic and electric power, VCM springs move the lenses to achieve auto focusing. In order to obtain exact focus, accuracy of VCM spring is required. VCM spring is an indispensable key component to lenses. Currently, VCM springs are manufactured through high precision etching process.

Main Applications: Cell Phones, Video Cameras, Camera Lenses on Tablets and Laptops.

Production Machineries: Our company has reliable suppliers providing high-quality raw materials for VCM springs. We engage in high technology and innovative strategies backed by professional teams of engineers. Furthermore, we also have advanced production machineries such as precise vacuum etching machines, automatic precise reel-to-reel exposure machines, development machines, pre-treatment cleaning machines, etc. to ensure product precision. 

Quality Inspection Instruments: Nikon VMR-6555 Automatic Image Measuring Instrument, Mitutoyo Tool Microscope.

Daily Production Capacity: As a reference, VCM springs with size of 8*8*0.04mm, daily production capacity is 1KK (for every 10 hours)
