Most sheet metal factories are essentially "process subcontractors" — they take orders, outsource what they can't do, and deliver after assembly. The "middleman premium" in outsourcing eats up 5%-15% of profit margins, while quality gaps and delivery uncertainties are the real "cost abyss."
Industry research shows: over 73% of sheet metal buyers rank "full-chain one-stop service capability" as the most important criterion for supplier selection.
As a company founded on spraying, DINGPRECISION has invested backward into laser cutting, CNC bending, and robotic welding, achieving full-process internal closed loop in 4 years.
Why reverse integration? Spraying is the "skin" of sheet metal parts — upstream process accuracy directly affects spraying results. Full-chain closed loop allows any problem to be traced to its root cause and resolved quickly.
Welding process upgrade: Intermittent welding → continuous TIG welding, eliminating microscopic gaps
Seal material upgrade: Open-cell foam → closed-cell EPDM, compression set <25%
Testing method upgrade: Batch sampling → 100% production line water spray test (IEC 60529 IPX4)
Curing process optimization: Extended curing time by 8 minutes to ensure complete cross-linking at weld areas
IP54 pass rate: 92% → 99.7%
Salt spray resistance: 1,000 hours (spec) → 1,200 hours (20% above spec)
Customer orders: increased 40% within 6 months, became preferred supplier
