1.Core Gear Manufacturing Process

Gear Blank Preparation

Adopt 20CrMnTiH alloy steel complying with GB/T 3077-2015. Forged and normalized to HB 187-229 for uniform grain structure and stable heat treatment performance.

Heat Treatment Process

Complete standardized heat treatment: 920±10℃ carburizing for 4 hours → 850±5℃ quenching → 180℃ low-temperature tempering for 2 hours. It achieves tooth surface hardness HRC 60-64, core hardness HRC 30-35, with 1.2-1.5mm effective hardened layer depth.

Precision Grinding Technology
Processed by Qinchuan YKZ7230 CNC worm gear grinder with Siemens 840D sl control system. Equipped with #120-#180 resin-bonded CBN grinding wheel. Standard parameters: 35m/s grinding speed, 0.005mm/rev feed rate, 80-100 gears wheel dressing interval.

100% Precision Inspection
Inspected by Zeiss Prismo CMM (≤0.0008mm accuracy) and Klingelnberg P26 gear measuring center. Strict tolerance control: Tooth profile error (f_Hα) ≤0.0015mm, tooth direction error (f_Hβ) ≤0.0012mm, pitch deviation (f_pk) ≤0.002mm, surface roughness Ra ≤0.2μm.

Performance Advantages for Carton Machinery

Ultra-Low Backlash & High Positioning Accuracy Total backlash controlled within ≤0.002mm, effectively eliminating transmission lag. It ensures ±0.03mm high-precision positioning for carton printing, die-cutting and folding-gluing machines, even at 350m/min high-speed operation.

Superior Wear Resistance & Long Service Life CBN precision grinding plus carburizing hardening treatment forms HV 850-950 high-hardness surface. The gear wear rate is reduced by 50% than ordinary gears, maintaining stable precision for 12-15 years under 24/7 continuous operation.

Low Vibration & Low Noise Operation Optimized 20° pressure angle modified involute tooth profile (module 2.5-5mm) limits meshing noise within ≤75dB(A). It reduces abrasion of cylinders, rollers and cutting tools, extending the overall service life of carton machinery.

Strong Environmental Adaptability Adopts QPQ black oxide anti-corrosion treatment on gear surface. It adapts to 40%-85% high-humidity workshop environment of carton factories, avoiding rust and precision attenuation.

2.Carton Machinery Frame & Precision Parts Machining Technology

HT250 Cast Iron Material

Carton machinery main frames and wall plates adopt HT250 gray cast iron (tensile strength ≥250MPa). It features high rigidity, excellent vibration damping and ultra-low thermal deformation. All core mechanical parts are produced with high-standard raw materials to match frame precision, zero assembly deviation.

Strict Industrial Tolerance Standard

All assembly surfaces and mounting holes comply with JB/T 13589 carton machinery industry standards:

Frame flatness: ≤0.015mm/m
Verticality & parallelism: ≤0.02mm/300mm
Key hole position accuracy: ≤0.015mm

Imported Gantry CNC Machining

Frames, wall plates and key mechanical parts are integrally processed byimported high-precision gantry CNC machining center (GB/T 18400.4 standard). One-time clamping milling eliminates repeated positioning errors for stable overall precision.

Machining Precision Parameters

X/Y/Z axis positioning accuracy: ≤0.015mm
X/Y/Z repeat positioning accuracy: ≤0.008mm
Spindle runout tolerance: ≤0.01mm

Stress Relief Annealing

All cast iron frames undergo high-temperature annealing, eliminating 98% internal casting stress. It effectively prevents plate warping and structural distortion during 24/7 high-speed operation of carton machinery.

Industrial Anti-Corrosion Treatment

Adopt SA2.5 level shot blasting + high-hardness electrostatic spraying (GB/T 9286 standard). Resists oxidation, dust and high-humidity corrosion, adapting to long-term carton factory harsh working conditions.

Core Performance Advantages
Excellent Vibration Damping & Stability HT250 cast iron reduces machine operating resonance by 40%, eliminating equipment jitter and precision fluctuation to ensure stable high-speed carton production.
Micron-Level Assembly Accuracy Ultra-precision structural parts match perfectly with carton machinery gears and transmission components. Overall assembly error ≤0.02mm, ensuring smooth synchronous operation.
Long-Term Precision Anti-Deformation Stress-free integral cast structure maintains original machining precision for over 10 years, no deformation or precision attenuation, reducing frequent equipment calibration.
Low Wear & Long Service Life High-rigidity frame disperses operating load, cutting core parts wear by 35%. It lowers carton machinery failure rate and maintenance cost, extending whole machine service life.

Corrugated Box Production Line Project for a Large Factory in Brazil

This video documents a turnkey corrugated box machinery project we delivered in partnership with a large manufacturing enterprise based in Brazil. The client’s primary objective was to establish a dedicated carton production facility equipped with reliable, high-efficiency machinery and backed by comprehensive, full-lifecycle technical support to facilitate their internal production, warehousing, and outbound logistics operations. Following multiple rounds of on-site supplier visits, technical comparisons, and proposal evaluations, the client selected us to supply a complete automated carton production line.

Upon delivery of the equipment, we dispatched expert technical engineers to the Brazilian facility to oversee on-site installation, including full-line assembly, wiring, integrated system commissioning, and trial production. We also provided systematic on-site training for the factory’s operators, maintenance staff, and management personnel, covering machine operation, routine maintenance, troubleshooting of common issues, and standard component replacement.
