Customizable Stainless Steel Spring Plungers for Molds & Fixtures

Spring plungers are essential precision fasteners for high-precision manufacturing and industrial automation, featuring an integrated SUS304 stainless steel body with a built-in high-elastic SUS304 spring and ball/pin tip. This design delivers stable pressure and consistent positioning, eliminating complex spring assembly and preventing spring displacement under pressure/vibration. Ideal for industrial clamping, indexing, latching and ejecting, it boosts mold and fixture stability and production efficiency.

Full SUS304 integrated design with industrial-grade raw materials, paired with high-strength bearing steel pins. Tips have four options: bearing steel (HRC55+ wear resistance), SUS304 (general corrosion resistance), ceramic (non-conductive/high hardness), nylon (scratch-proof). Full-process CNC machining and multi-level inspection ensure consistent performance and zero individual quality differences.

Install with matched mounting type/standard tools, avoid over-torquing; add thread inserts for soft bases and ensure vertical, burr-free mounting holes. Custom products include dedicated manuals and technical guidance. Quality assurance covers 100% pre-shipment testing, 500,000 compression cycles (≤5% preload attenuation), salt spray corrosion resistance, RoHS2.0 compliance, one-stop customization with sample confirmation, and 24/7 after-sales support (free non-human damage replacement).

Full SUS304 parameter customization (standard/non-standard), shorter lead times via dedicated production lines and raw material inventory, consistent quality with standard products, and one-on-one technical matching by mold/fixture experienced engineers to avoid blind customization and ensure perfect application fit.
