WORKSHOPS

The workshop is the core site of the company's production operations and the key link where raw materials are transformed into finished products. Below is a brief introduction to the workshop's basic situation:

 MAIN FUCTIONS

• Production Assembly: Assemble and fit various components of products in accordance with process requirements.

• Quality Inspection: Conduct quality control at every production stage to ensure products meet required standards.

• Equipment Operation and Maintenance: Operate all types of workshop equipment and perform routine maintenance.

• Material Management: Manage the requisition, storage, and recording of production materials.

MANAGEMENT REQUIREMENTS

• Safety Production: Strictly comply with safety operating procedures and prohibit any rule-violating operations.

• Quality Awareness: Uphold the principle of "Quality First" — do not accept, do not produce, and do not pass on defective products.

• 6S Management: Maintain a clean and orderly workshop by implementing Sort, Set in Order, Shine, Standardize, Sustain, and Safety.

• On-Time Delivery: Complete tasks according to the production plan to ensure timely delivery.

 BELOW ARE OUR WORKSHOPES

1, WORKSHOP NAME：FULLY ENCLOSED CNC MACHINE AND ROBOTIC ARMS WORKSHOP

     FUNCTION: The equipment shown in the picture is primarily used for machining core mechanical components such as Roots blowers and rotary blowers.Cylinder blocks and end covers for the BK series three-lobe Roots blowers and main components for the HC-S series low-noise rotary blowers.

2, WORKSHOP NAME：MACHINEING CENTER

      FUNCTION: This type of equipment primarily uses computer programs to control cutting tools moving along multiple axes, layer by layer removing excess metal from the raw workpiece (blank) to achieve the final dimensions and precision requirements.

3,WORKSHOP NAME: 5-AXIS VERTICAL MACHINING CENTER

   FUNCTION: Five-axis simultaneous machining, one‑setup completion: This is its most core advantage. Through the simultaneous coordinated motion of five axes (the three linear axes X/Y/Z plus two rotary axes), it can complete multiple operations such as turning, milling, and drilling on an impeller in a single clamping. This eliminates positioning errors caused by multiple setups, which is the fundamental basis for ensuring high precision in impeller machining.

4, WORKSHOP NAME：A TESTING WORKSHOP

    FUNCTION: A dedicated area where products are inspected for functionality, performance, and durability to ensure they meet quality standards before leaving the factory.

5,WORKSHOP NAME：AIR BEARING INSTALLING WORKSHOP

    FUNCTION: Various types of high-efficiency centrifugal blowers are installed utilizing air bearing technology.

Customer Project----The Ecuador Sewage 

The stable and low-noise performance of the B-Tohin fan has earned high praise from property owners.
Recently, the complete set of B-TOHIN three-lobe Roots blowers was successfully put into operation in a mountainous wastewater treatment project in Ecuador. Located in a tropical rainforest, the equipment requires uninterrupted aeration for sedimentation tanks throughout the year.

By optimizing the three-lobed rotor structure and adopting a dual-layer noise reduction design, the unit delivers stable air pressure and minimal vibration under full-load operation, with outstanding noise performance, perfectly adapting to the local high-temperature and high-humidity complex environment. After multiple rounds of on-site testing by foreign engineers, all operational data met standards. Its stable and low-noise advantages effectively resolved the past issues of high equipment failure rates and noise disturbances, earning high recognition from the project stakeholders.

The successful implementation of this project marks another landmark case for B-TOHIN's domestic fan exports to Latin America, showcasing the robust technical capabilities of Made-in-China in the field of environmental aeration equipment.
