Industry Application
Precision Steel Strip for IT and Electronics
IT hardware is where thin gauge stops being a convenience and becomes the design constraint. Yongxin has supplied the IT sector since the plant opened and rolls the gauges that shielding, contacts and stiffeners need.
Industry Pain Points
What Usually Goes Wrong in This Industry
Springback Changes Between Batches
A progressive die tuned for one hardness produces out of tolerance contacts when the next coil is softer or harder.
Surface Contamination Before Plating
Residual rolling oil ruins selective plating and conductive coating adhesion.
Flatness in Very Thin Strip
Shielding cans and stiffeners are unforgiving about coil set and edge wave at 0.05 to 0.2 mm.
Narrow Slit Width Tolerance
Contact strip fed into a high speed press needs edge condition and width held tightly.
Customer Requirements
What Buyers in This Industry Ask For
- Repeatable temper so die setting stays valid across deliveries
- Degreased clean surface ready for plating or coating
- Narrow slit widths with a controlled edge
- Grade cross reference between JIS, ASTM and EN designations
- Sample approval before a production tool is committed

Where the Strip Ends Up
EMI Shielding Cans
Thin stainless or cold rolled strip stamped and formed into shielding frames and lids
Connector Contacts and Springs
Harder temper stainless strip where springback and fatigue behaviour decide contact force
Stiffeners and Brackets
Flat thin strip supporting boards and displays where thickness variation shows up as assembly stress
Hinges and Sliding Parts
Strip with a controlled surface finish where wear and friction matter
