How long is the sample lead time for new customized parts
There is no need for expensive hard steel molds for etching, only digital photomasks are required. Drawing confirmation → photomask production → trial etching sample takes only 24–48 hours. For small batch trial production after sample confirmation, delivery can be completed within 3–5 working days; mass production delivery schedule will be adjusted according to order quantity, normally 7–15 working days for million-piece orders. -
Will etching produce burrs, scratches or residual stress on parts
Photochemical etching belongs to normal-temperature cold chemical subtractive processing, with no mechanical extrusion force or high-temperature heat influence. The finished product has completely burr-free edges, no tool scratches, no residual internal stress, and will not warp or deform after long-term stacking assembly. The surface roughness Ra can be adjusted according to customer demands to provide ideal bonding base for PVD coating, electroplating and other post-processing. -
he digital transformation of the energy
We support 304/316L stainless steel, TA1/TA2 pure titanium, titanium alloy, cupronickel, Invar, copper, aluminum alloy and other thin metal substrates. The applicable thickness ranges from 0.05mm to 1.0mm, which perfectly matches raw material requirements of hydrogen energy bipolar plates, electronic shielding parts, precision shims and sensor components. Custom corrosion solutions will be configured for different metals to retain original conductivity, corrosion resistance and mechanical properties of substrates. -
What are the accuracy tolerances of chemical etching compared with stamping and laser cutting
Our precision etching dimensional tolerance reaches ±0.01mm~±0.025mm, channel depth tolerance up to ±5μm; stamping tolerance is usually ±0.08mm with deformed warpage for ultra-thin plates; laser cutting has thermal deformation and rough cutting edges with large size deviation for complex micro-channels. Etching realizes burr-free, stress-free integrated forming for complex graphics, and flatness can be controlled within 0.01mm for 0.1mm thin plates. -
Can you realize double-sided differential depth etching and one-time forming of complex flow field patterns
Yes. We adopt synchronous double-sided gradient spraying etching technology, which can set different groove depths on the front and back of one plate at the same time, such as shallow gas flow grooves on one side and deep cooling flow grooves on the other side of bipolar plates. Serpentine, interdigitated, parallel composite flow fields, dense micro-hole arrays, positioning bosses and sealing grooves of any complex shape can be integrally formed in one process without secondary CNC or drilling operations. -
What main products do you customize via precision metal etching
Core customized parts cover three major tracks: 1.Hydrogen energy industry: PEM fuel cell metal bipolar plates, PEM electrolytic water titanium bipolar plates, flow field plates, sealing frames; 2.Electronic precision parts: electromagnetic shielding sheets, conductive shims, heat dissipation fin sheets, sensor metal substrates, filter mesh sheets; 3.Mechanical & medical precision components: ultra-thin gaskets, micro spring sheets, medical implant auxiliary metal parts, instrument thin metal structural parts. -
Is there a minimum order quantity (MOQ) for etched metal parts
No MOQ limit. We support 1–10pcs laboratory prototype sampling, hundreds of small-batch trial orders, and million-level mass production orders for vehicle manufacturers. Multiple different model parts can be arranged on one board for batch etching to reduce unit cost for small customers. -
Can you provide one-stop post-processing services such as coating, laser welding and cleaning
We provide full-process one-stop supporting services: precision etching → ultrasonic electronic-grade cleaning → vacuum drying → PVD magnetron sputtering anti-corrosion conductive coating → laser welding sealing → full-size dimensional inspection → helium air tightness testing → vacuum packaging. Customers can receive finished assembled semi-products directly without finding third-party processing factories separately.
