Applications Across Sectors

Education Devices

Precision Parts in Action

Server Rack Chassis Fasteners

Structural rivets and self-clinching studs

Server enclosures require durable hardware. Automatic lathes mass-produce high-strength knurled steel rivets and clinch studs, ensuring perfect alignment, vibration resistance, and rapid assembly in data centers.

Coaxial RF Connector Pins

Pins for high-frequency RF connectors

High-frequency communication relies on flawless connectivity. CNC Swiss lathes precision-turn miniature brass and copper inner conductor pins down to sub-millimeter scales, guaranteeing stable data transfer.

Mobile Device SIM Card Trays

Ejector pins and return tension springs

Miniature ejection mechanisms demand exact tolerances. CNC Swiss lathes machine ultra-thin micro-pins, while precision spring machines produce reliable return compression springs to ensure smooth tray ejection.

High-Current Battery Spring Contacts

Pogo pins and compression springs for docks

Charging interfaces require resilient paths. Automatic lathes machine hollow brass plungers, which combine with integrated compression springs to maintain constant force for uninterrupted power delivery.

Semiconductor Test Probe Pins

Micro-pins for IC testing interfaces

IC testing requires ultra-fine probes. CNC Swiss lathes turn ultra-thin test pins with micron-level tips, which work with miniature internal springs to absorb impact and ensure stable testing contacts.

Smart Home Appliance Solenoid Valves

Valve plungers and tension reset springs

Smart appliances control liquids via micro-valves. CNC Swiss lathes produce highly concentric magnetic plungers, while precision-coiled extension springs ensure instant, leak-free return actuation.

Industrial PCB Terminal Blocks

Threaded brass inserts and clamping screws

Secure PCB wire termination requires robust metallic threads. Automatic lathes rapidly turn and thread knurled brass terminal inserts and steel screws, ensuring high mechanical strength and conductivity.
