Strict Quality Inspection Process

A complete quality inspection process is essential for mass production, and every step of quality control needs to be strictly enforced, ensure the goods are in control with nice quality.

IQC- Incoming Quality Control

We Screen the supply chain strictly, stable cooperative suppliers provide us with material, each components are sampled on each batches, ensure components meet the product requirements and prevent batch quality defects in advance.

  • Raw material inspectionCheck the color material without any impurities and, check the features meet the requirements of the order.

  • Accessory inspectionCheck the appearance, parameter and craftsmanship of the accessories which can meet the standards, randomly check the accessories can be installed normally.

  • Package inspectionCheck the thickness and printing pattern of box, the integrity of silkscreen and label.

ISC- Initial Sample Confirmation

Initial sample is confirmed by client, mass production should be same as it, the production process is pushed as the initial sample.

  • Determine the technical parameters of the product according to the needs of the region and the client, refine and adjust the technical parameters of each components.

  • Produce the initial sample according to the incoming material, which should be in full compliance with the comfirmed sample.

IPQC- In Put Process Quality Control

QC take online inspection during production process, 100% goods need to past electrical parameter test, earth resistance test and high voltage test. Pay more attention to products details in quality, which is strictly controlled by production line leader.

Assembly Inspection

Check the components are soldered and screwed correctly, install each components without burr or gaps.

Technical Parameter Inspection

100% check the products, which compliance with the basic parameters, they should be tested by the technical performance one by one, included earth resistance teste and high voltage test.

FQC- Final Quality Control

According to the qty. of the order, the QC take random inspection in accordance with the proportion of distribution and conduct a comprehensive assessment of appearance, function, performance, etc. Goods are tested by inspection equipment, precise data as standard, ensure that they are consistent with the Initial sample and order details.

  • Check the packing box, manual, technical data stickers and a series of packaging.

  • Check the appearance of each components and fan, ensure the fan comply with international certificate.

  • Measure the dimension correctly, check the quantity of each components completly.

  • Check the basic technical parameters of each components and the fan by professional testing equipment.

  • Arrange special product testing according to different markets and client's requirements.

  • Check the spare parts are complete, which is convenient to after-sale service.

Electric Fan Testing and Inspection

With well-equipped testing equipment and strict inspection standards, precision instruments and test data speak for quality, ensure excellent performance of electric fan.
A

Electrical Parameter Test

Check the basic technical parameters of fans, included voltage, frequency, power.

B

Earth Resistance Test

Check the earth resistance data of fans, ensure the safety factor.

C

High Voltage Test

Simulate the extreme conditions by high pressure in actual operation, check the performance of the fans which is tested to meet the expected standards.

D

Wind Speed Test

Check the air speed data of each fans.

E

Rotational Speed Test

Check the rotate speed data of each fans.

F

Noise Test

Check noise data of each fans, bring coolness quietly.

G

Life Test

Run the fans for a long period, testing the functional of fans, testing the life of the motor, to provide better technical support.

H

RoHS Test

It is a device used to detect whether the content of hazardous substances in electronic and electrical products complies with the RoHS directive, ensure compliance with environmental standards in Europe and safeguard user health and safety.

I

Tilt Test

Check the stability of the fans, ensure that it can operate stably at a 10° tilt angle inclined slope without tipping over or abnormal situation.

J

Finger Test

Check the safety of fans, the adult fingers or baby fingers can not be inserted to the fan grill, avoided safety risks.

K

Drop Test

Check the packaging stability of electric fans, simulate collision situation during transportation, ensure the fan can operates normally without ant damaged after the drop test at a certain height.

L

Tension Test

Check the fastness of the power cable of the electric fans, perform a tensile test on the power cord of the fan with the rated tension which is similar as the usual use, ensure that there is no damage after the test.

The Key Core Of Electric Fan - MOTOR

Our factory has an independent motor workshop, which can control the core technology of the fan well during production, ensure stable performance and improve the user experience of consumers.
Step 1

Winding

Wire is evenly wound into coils on the stator or rotor according to specifications. This process requires precise control over the number of turns, tightness, and arrangement of the coils to ensure the motor's performance and efficiency. Check the resistance after winding to ensure it meets specifications.

Step 2

Binding

After winding is completed, fine wire or straps are used to secure the coils in place, maintaining their shape and preventing movement. This step is also crucial for enhancing the structural stability of the motor. Ensure that the binding materials are heat-resistant to suit the motor's operating environment well.

Step 3

Stator Testing

It is a crucial step to ensure the normal operation of an electric motor. Included visual inspection of stator, resistance test, hi-pot test. Record test results for future analysis and tracking, ensuring they are within a safe range.

Step 4

Rotor Shaft Insertion

Install the rotor onto the electric motor shaft properly. Ensure all components are within the appropriate temperature range to avoid issues caused by thermal expansion or contraction. Check that the rotor rotates smoothly without any binding or obstruction.

Step 5

Stator Impregnation

The process involves treating the stator coils with insulating varnish, enhance insulation performance and improve heat resistance. Control the time and temperature of the impregnation and baking processes to avoid over or under-curing.

Step 6

Bearing Pressing

Install bearings onto the motor shaft or stator, make sure to maintain alignment during the pressing process, prevent unnecessary wear, ensure ensure smooth rotation.

Step 7

Motor Assembly

Combining various components to a complete electric motor in sequence, check all connections and components fix tightly, ensure there are no loose parts or anomalies.

Step 8

Finished Motor Testing

Ensure that all the motor meet quality standards before fans production, test the load performance of motor to ensure it operates normally and the temperature rise isn't exceed specified limits under rated load. Motors can operate smoothly without abnormal sounds.

Trustworthy Certification

Our household fan earn various certificate from various organizations.
