Auxiliary processing equipment: efficient synergy, unlocking large-scale production

Lianjiang base provides supporting processing equipment to achieve rapid transformation from rough to semi-finished products: 

1. Multi-axis hydraulic drilling machine

Function Function: Processing mounting holes and heat dissipation holes on the heating plate, inner liner and other parts, supporting 6-axis synchronous operation.

Efficiency Comparison: Traditional single-axis equipment takes 120 seconds to process 1 piece, Osno six-axis model takes only 20 seconds, efficiency increased by 500%.

2. CNC automatic tube cutter & round molding machine

Function: Cutting tubes for shell bracket and roll round the edges of the inner liner with an accuracy of ±0.05mm. 

Innovative design: laser positioning + servo press-bending system, avoiding scratches on the metal surface, scrap rate <0.1%.

Heating Component Manufacturing Equipment: Master of Balancing Safety and Efficiency

Osno independently researched and developed fully automatic production line for heating components, breaking through the technological bottleneck in the industry: 

1. Tubular Heating Wire Winding Machine for Rice Cooker Function: Winding Nichrome alloy resistance wire, wire diameter precision ±0.01mm, support double helix structure.

Technical breakthrough: AI tension control system, resistance value fluctuation <±1%, life expectancy of more than 100,000 times start and stop.

2. Vacuum powder filling machine 

Function: inject magnesium oxide insulating powder into the heat pipe. Density deviation ≤ 2%, thermal conductivity up to 45W/m-K. 

The first in the industry: negative pressure filling process, powder filling rate ≥ 99%, to eliminate the hidden danger of local overheating.

Quality testing equipment: strict standards, guarding product safety

Osno integrates German testing technology to create a closed loop of quality control for rice cookers: 

1. High-precision voltage tester Function: Simulate 5000V high voltage testing of the insulation performance of the heating plate, leakage current detection sensitivity up to 0.1mA. 

certification support Function: Data is automatically uploaded to the cloud and complies with global safety standards such as IEC 60335-1 and GB4706.

2. 3D Machine Vision Inspection System 

Function: Scanning thickness of liner coating, uniformity, recognition accuracy of 0.005mm, replacing manual quality inspection.

Customer value: Saving 70% of labor cost of quality inspection for Granz, and the defect leakage rate is close to zero.

Production Process Synergy: Flexible Manufacturing, Activating Production Line Efficiency

Osno realizes efficient synergy in the whole process of rice cooker production through equipment interconnection and process optimization: 

Intelligent production line design: 

Four-station centrifugal casting machine → automatic pipe cutting machine → multi-axis drilling machine forms a continuous processing flow to reduce material turnover by 60%. The drilling machine forms a continuous processing flow, reducing material turnover by 60%.

Modularized design supports switching IH heating plate/traditional heating plate production line within 1 hour to meet the demand for mixed production of multiple models.

Human-machine collaboration mode: 

High-precision links (such as resistance wire winding) using fully automated equipment, the introduction of collaborative robots in complex assembly workstations, the overall efficiency increased by 40%.

Global Service Case: Technology Empowerment, Driving Customer Success

Mexican Customer: Osno's fully automated production line (including centrifugal casting + hot plate lathe) was introduced to achieve localized mass production, and the cost was 35% lower than imported finished products.

India: Jointly developed a low-cost manual centrifugal casting machine + semi-automatic winding machine combination program to help small and medium-sized enterprises to increase production capacity by 3 times.

Osno promises: 

All equipment enjoys 1 year warranty, lifetime technical support 

Local warehousing of spare parts in Bangladesh, Turkey and other 6 countries, 72 hours of rapid response 

Free process parameter package and production management SOPs
