Cost & Efficiency Upgrade for Heavy Machinery Fabrication

Client: A leading heavy machinery manufacturer (specialized in excavator frames, loader chassis, construction steel structures)

Challenge: High custom fixture costs, long mold change time, high welding deformation & rework rate, low production flexibility for small-batch/multi-variety orders

Solution: 5 sets of 2000*1000mm 3D flexible precision welding tables (D28 hole system, high-strength cast iron, precision ground surface)

• Fixture Cost: Custom-made dedicated jigs for each workpiece type; annual fixture R&D & manufacturing cost > $85,000; 300+ sets stored, occupying 120 ㎡ warehouse space
• Production Efficiency: Mold change & debugging time 4–6 hours per workpiece type; line downtime frequent; labor idle cost high
• Quality & Rework: Positioning error ±1.5mm; welding deformation rate 18%; rework & material scrap cost > $42,000/year
• Flexibility: Unable to adapt to custom small-batch orders; production scheduling delayed, order delivery cycle extended by 25%

1. Fixture Cost Cut by 72%

   One set of modular fixtures adapts to excavator frames, loader chassis, steel beams, and 20+ workpiece types. No custom jigs needed; annual fixture investment reduced from $85k to $23.8k; warehouse space for fixtures cut by 85%.

2. Mold Change Time Reduced by 85%

   Quick assembly/adjustment of standard modules (clamps, supports, positioning blocks); mold change from 4–6 hours to 30–45 minutes; production line uptime increased by 32%.

3. Welding Quality & Rework Rate Optimized

   Positioning accuracy ±0.05mm; flatness & parallelism guaranteed; welding deformation rate dropped from 18% to 3.5%; rework & scrap cost reduced by 82% ($7,560/year).

4. Production Flexibility & Delivery Improved

   Fast switching between small-batch custom orders and mass production; order delivery cycle shortened by 28%; customer satisfaction up 40%.

• Total production cost reduced by 31%
• Overall welding efficiency increased by 45%
• Annual direct cost savings: $95,640
• Payback period: 5.8 months

"The 3D flexible welding tables completely solved our fixture and efficiency pain points. We no longer waste money on custom jigs, and we can quickly switch between any workpiece. Quality is stable, costs are down, and we’re more competitive for custom orders."
