Miniature Compression Spring

Miniature Compression Spring features thin wire and small coil diameter. It generates mild axial thrust for short-stroke reset inside cramped component housings. Fine-wire manufacturing demands consistent coil spacing and flat end faces. Poor end finishing leads to tilting and jamming inside confined mounting holes. Miniature Compression Spring delivers soft thrust without generating excessive impact force for delicate small-scale mechanisms. A Miniature Compression Spring fits compact housings with strict dimensional constraints.

Electronic switches and button sub-assemblies deploy this part for light rebound performance. Precision instruments, compact stationery and toy internals use it for short-distance push-back functions. Miniature medical-device sub-components require gentle compression support with limited available installation room. All working environments impose tight dimensional constraints and low-force operating demands.

Buyers submit drawings or physical samples to define free height, thrust rating and hole-fit dimensions. Shengzhou Deyuxiang Hardware Accessories Co., Ltd. responds within a 12-hour window. Feasibility assessment and quotation complete over 3-5 working days. Sample production takes 10-30 working days before bulk-order start-up. Minimum order quantity is 5000 pieces; mixed-model ordering for single shipments is negotiable by product value.

Inspection includes random sampling plus optional full inspection before packing. Operators verify small-coil dimensions, free-height consistency and light-thrust uniformity; third-party inspection can proceed. Heat-treatment stabilises fine-wire elasticity and prevents performance drop after frequent light compression. Export packaging guards tiny coils against crushing, utilising isolated unit protection, secured inner boxes and labelled export cartons. Standard-item lead-time 7-15 working days; custom-item lead-time 15-30 working days. Repeat orders get 3-10 working-days priority scheduling. EXW and FOB support USD and RMB payment.
