Qiaosen Machinery Auxiliary Equipment Series: In-depth Analysis of MT Material Uncoiler, Performance Test, Selection Guide & On-site Application Data

Introduction

As essential auxiliary supporting equipment for precision stamping production lines, material uncoilers directly determine the stability of coil feeding, production continuity, raw material utilization and overall stamping efficiency of the whole line. Dongguan Qiaosen Machinery completes full-chain intelligent stamping supporting layout on the basis of main punch press equipment, and independently develops and manufactures MT series automatic & non-power material uncoilers, matching all ST/STB/STC/STA series punch presses of the brand.

This press release adopts professional Q&A structure, combined with laboratory performance test data, parameter comparison, scenario-based model selection, official product hyperlinks and long-term customer actual operation data, comprehensively interprets the structural advantages, load performance, feeding stability, durability and purchasing selection scheme of Qiaosen MT material racks, providing reliable reference for global buyers to configure complete automatic stamping production lines.

1. Professional Performance Evaluation & Laboratory Test Data of Qiaosen MT Material Uncoiler

All test data comes from Qiaosen Machinery industrial laboratory continuous feeding endurance test, load-bearing deformation test, material strip stability test, anti-fatigue operation test and long-time operation stability verification.

Q1: What are the structural material and mechanical performance test data of Qiaosen MT material rack main frame?

Laboratory Measured Data

Main frame: Integral thickened high-strength steel plate welded structure, with overall stress relief aging treatment. Under maximum rated load condition, frame deformation value is ≤0.15mm, no bending, no shaking, far better than ordinary material rack 0.4mm deformation industry standard.
Mandrel expansion structure: Precision machined mandrel, pneumatic & hydraulic dual expansion mode. Expansion concentricity error ≤0.08mm, stable clamping of coil materials without slipping, loose coil and offset deviation.
Pressure arm assembly: Custom high-strength rubber pressure roller with high wear resistance. Surface hardness reaches Shore A 85, continuous pressing wear amount after 500,000 times of coil uncoiling is only 0.12mm, effectively preventing coil scattering and material jumping during high-speed feeding.
Transmission structure: Adopts high-precision bearing transmission system, mechanical rotation resistance reduced by 35% compared with conventional racks, low power consumption and smooth uncoiling without jamming.

Q2: What are the core parameter indicators and feeding stability test data of MT series?

Qiaosen MT series covers non-power and power-driven automatic models, adapting to thin metal strips, stainless steel coils, copper strips, aluminum strips and hardware stamping raw coils. Special test data is as follows:

Applicable material thickness: 0.1mm ~ 3.0mm metal coil
Coil inner diameter adaptation: Φ450~520mm; Maximum outer diameter of coil: Φ1200mm
Maximum load range: 120kg ~ 2000kg, supports customized heavy-duty expansion up to 10 tons
Maximum applicable material width: 200mm ~ 800mm, non-standard customized up to 1800mm
Stable feeding speed: Automatic model maximum stable speed 15m/min, no material pulling, no tension deformation of strip during full-speed continuous uncoiling.
Strip offset error during continuous feeding: Whole process control ≤0.2mm, perfectly matching high-precision stamping production requirements.

Q3: What is the 72-hour continuous uncoiling endurance test data of Qiaosen MT material rack?

72-hour uninterrupted continuous feeding test (MT-500 model, 1.0mm stainless steel coil, full-load operation)

Total continuous uncoiling running time: 72h non-stop operation
Total feeding length accumulated: 64800m
Unplanned shutdown and jamming failure times: 0 time
Mandrel expansion structure precision attenuation: Only 0.06mm after long-time high-load operation
Pressure roller wear performance: No obvious aging, cracking and abrasion failure, service life 1.8 times longer than ordinary similar equipment.

Q4: What is the energy consumption and cost advantage comparison test with mainstream industry material racks?

Under identical working conditions (same load, same material width, same daily running time), horizontal comparison test between Qiaosen MT automatic uncoiler and ordinary market material racks:

Test Item	Qiaosen MT Series Uncoiler	Ordinary Market Material Rack	Performance Advantage
Frame deformation under full load	≤0.15mm	0.4mm	62.5% deformation reduction
Feeding offset error	≤0.2mm	0.6mm	Precision improved by 66.7%
Daily power consumption (automatic model)	0.8kW·h	1.5kW·h	Energy saving 46.7%
Pressure roller service life	18000 working hours	10000 working hours	Service life increased by 80%
Whole machine failure rate per year	≤1.2%	5.8%	Failure rate reduced by 79.3%

Data Conclusion

Qiaosen MT material rack has obvious advantages in structural rigidity, feeding precision, energy saving, durability and operation stability, which can effectively reduce later maintenance cost and production line abnormal shutdown loss.

2. Purchasing Guide, Full Model Parameter Comparison & Official Product Hyperlinks

Combined with laboratory test data, we answer core purchasing questions through Q&A, sort out complete model parameter table, give targeted selection suggestions for different production lines, with embedded official product links for direct jump viewing.

Q5: What core indicators should be prioritized when purchasing stamping auxiliary material racks?

According to stamping production line matching standards, 5 core detection indicators: frame load-bearing rigidity, mandrel expansion precision, feeding strip stability, component durability, matching adaptability with main punch press. At the same time, select models according to coil weight, material width, thickness and production line speed, avoid blind selection only by load parameters.

Q6: Qiaosen MT full series model parameter comparison & application scenario selection

Qiaosen MT series includes non-power light-duty, automatic medium-duty and heavy-duty customized models, fully matching with the whole series of Qiaosen punch presses. Detailed parameter table with official direct links is as follows:

Model Series	Maximum Load	Applicable Material Width	Material Thickness	Core Advantages	Suitable Scenarios
MT-100 Non-power Uncoiler	120kg	170mm	0.1~1.2mm	Compact size, no power supply required, simple operation, low cost	Small batch thin strip stamping, small hardware workshop, supporting small tonnage ST punch press
MT-200 Light Automatic Rack	500kg	200mm	0.35~1.6mm	Stable pneumatic expansion, automatic feeding, easy maintenance	Medium small coil production, supporting ST/STB series punch presses
MT-500 Medium Heavy-duty Uncoiler	1200kg	500mm	0.35~3.0mm	High rigidity frame, double pressure arm, high speed stable feeding	Conventional mass production line, auto parts stamping matching STB/STC punch press

Q7: Data-driven targeted purchasing selection suggestions for different production demands

Small processing workshops, small thin coil stamping (≤120kg load)

Purchase suggestion: Prefer MT-100 non-power material rack. No motor configuration, flexible layout, small floor space, fully meets small-batch single-piece stamping feeding needs, with highest cost performance.
Medium daily mass production, conventional metal coil (500~1200kg load)

Purchase suggestion: Prefer MT-200 / MT-500 automatic series. Stable automatic uncoiling, perfect matching with ST/STB medium tonnage punch presses, realize continuous feeding without manual intervention, improve production line efficiency.
Large heavy coil, wide plate metal stamping (≥2000kg load)

Purchase suggestion: Choose MT-800 heavy-duty hydraulic expansion material rack. Super strong load-bearing rigidity, wide material width adaptation, suitable for large structural parts and wide coil automatic stamping production lines.
