This is a TV Wall Bracket produced by precision metal stamping at our 20-year-old Dongguan factory. You get a flatness of 0.08mm across the mounting plate, a hole-to-hole tolerance of ±0.05mm, and a surface finish of Ra 1.6—all at a lead time of 15 days for standard sizes. We use SPCC or SUS304 steel, hardened to 400–500 HV, so your bracket holds a 65-inch TV without flex or creep.
How Our Die Set Controls Flatness and Hole Position
We build progressive dies with a hardened D2 punch and die insert. The die clearance is held at 5% of material thickness—no more, no less. That gives you clean sheared edges without burrs exceeding 0.05mm. The pilot holes are ground to ±0.01mm, so every bracket in a 10,000-piece run has the same hole pattern. We check flatness on a granite surface plate with a 0.001mm indicator. If a part exceeds 0.08mm flatness, it is rejected, not reworked.
SPCC vs SUS304: Which Steel We Recommend for Your TV Load
For a 32-inch to 55-inch TV, we recommend SPCC cold-rolled steel at 2.0mm thickness. It gives you a yield strength of 280 MPa, and we zinc-plate it to 8–12 microns for corrosion resistance. For a 65-inch or larger TV, or for outdoor use, we switch to SUS304 stainless steel at 2.5mm. That material has a yield strength of 520 MPa and needs no coating. We will not stamp thinner than 1.5mm for a swivel arm design—bending stress will crack it over time.
Bending and Springback Compensation in the V-Die
Our stamping press is a 160-ton CNC servo machine. We pre-calculate springback angle using a modified Siebel formula, then over-bend by 2 to 3 degrees. After the first 50 pieces, we measure the bend angle with a digital protractor and adjust the die shim if needed. Final bend angle tolerance is ±0.5 degrees. The bend radius is kept at 1.5 times material thickness to prevent micro-cracks on the outer surface.
Surface Finish and Coating Options That Prevent Rust
Standard finish is bright zinc plating, 8–12 microns, with a clear trivalent passivate. That passes a 72-hour neutral salt spray test per ASTM B117. If you need more, we offer black electrophoretic coating (15–20 microns) which passes 200 hours. For a matte look, we can powder coat to 60–80 microns, but that adds 3 days to lead time. Raw surface roughness after stamping is Ra 1.6; after coating, it stays below Ra 3.2.
Inspection Before Every Shipment: CMM and Pull-Test Data
Every batch of TV Wall Brackets goes through a three-stage check. First, we run a first-article inspection on a CMM (Coordinate Measuring Machine) and record 15 critical dimensions. Second, we do a pull-test on the mounting arm—applying a 150 kg static load for 10 minutes, then checking for permanent deformation under 0.2mm. Third, we sample 5 pieces per 500 and measure hole position, flatness, and coating thickness. You get a PDF inspection report with each shipment, no extra charge.
Packaging, Logistics, and Lead Time for Your Production Line
Standard lead time is 15 days for a stamped TV Wall Bracket from drawing approval to shipment. We pack brackets in individual EPE foam bags, then into 5-layer corrugated cartons with a 120 kg stacking strength. Each carton holds 20 pieces. For sea freight, we load into pallets with stretch wrap; for air freight, we use reinforced export cartons. We ship DDP to USA and EU warehouses if you need door-to-door delivery.

How We Handle Prototypes vs. Mass Production Runs
We do not ask for a minimum order quantity. Send us a 2D drawing or a 3D STEP file, and we will make 1 to 5 prototype pieces using a soft tool or wire-cut die. Prototype lead time is 5 days. Once you approve the sample, we harden the die and start mass production. Tooling cost is amortized over your order quantity, and we refund 50% of tooling cost after 10,000 pieces. For repeat orders, we keep the die in storage for 3 years at no charge.
Do you have a minimum order quantity?
No MOQ—we accept 1 prototype piece or 50,000 production pieces with the same quality system.
Can you customize the hole pattern or arm length?
Yes, we modify the die for any hole pattern, arm length, or VESA standard within 3 days of drawing approval.
How do you guarantee quality on a stamped part?
We use a CMM first-article inspection, a 150 kg pull-test on the arm, and a 5-piece per 500 sampling for dimensional and coating checks.
What is your fastest lead time for a custom TV Wall Bracket?
Prototype in 5 days, and mass production in 15 days after you confirm the sample.
