Lamp Shade Inspection Process

Lamp Shade Inspection Process

Oh, No. are There Any Customers Who Don’t Know the Production Standard of Our Lampshade? Then They Should Watch This Video Carefully.

First Product Inspection

First of All, We Will Conduct the First product Inspection of the Product During the Production Process.

Detect Color

Check Whether the Color of the Lampshade is Consistent with the Color Plate.

Detect Visual

Check Whether the Appearance of the Lampshade Has Black Spot, Drawing Scratch, Concave Convex Shrinkage, Etc.

Detect Dimension

Check Whether the Lamp Shade Size is Within the Allowable Range of the Engineering Drawing.

Detect the Fitness

Whether One Assembly of Lamp Shade and Aluminum Groove Can Be Clamped Tightly.

Instrument Test

Then We Carried Out a Series of Tests on Our Lampshade Through Our Professional Equipment, Including the Ultraviolet Glow,Wire Burning,High and Low Temperature,Light Transmittance and Dark Room IES.

Ultraviolet Glow

It is Mainly Used to Test Our PC Lampshade to Simulate the Aging Test of Artificial Light Source in the Scene of Sunshine, Rain and Dew. the Qualification Standard of the Test is That the Lampshade Should Remain Flexible, Non Fragile and Free of Cracks.

Wire Burning

Plastic Glow Wire Tester Test the Lamp Cap Made of PC According to the Burning Point Required by the Customer Test the Product Under Extreme High Temperatures a General Standard Test is at 750 Degrees.

High and Low Temperature

Whether the Simulated Lampshade Will Be Brittle Under the Environment of High Base Temperature and Extremely Low Temperature.

Light Transmittance

Use the Integrating Sphere to Test the Whole Lamp First, and Then Test the Bare Lamp to Get the Report. Divide the Lumen of the Bare Lamp by the Lumen of the Whole Lamp to Get the Luminous Transmittance.

Dark Room IES

Ies Light Distribution Test Means That the Light Intensity Distribution of Light Source or Lamp in All Directions of Space Can Also Test the Average Light Speed Angle, Measure the Color Temperature, Average Illuminance, Annular Luminous Flux, Ugr Value, Etc.

Heat, Cold, Dry and Wet Resistance Test

The Programmable Constant Temperature and Humidity Tester Can Test the Heat, Cold, Dry and Humidity Resistance of the Product.

Conduct High and Low Temperature Tests on Products Made of PC Materials Through Four Repeated Cycles of Extreme High Temperature 90 ° C and Low Temperature – 30 ° C.

After the Test, Our Lamp Cap and Lampshade Will not Turn Yellow, and the Appearance Will not Be Brittle, and There Will Be No Cracks to Maintain a Certain Degree of Toughness, Which Means That the Lamp Cap and Lampshade Have Passed the Test.

Thickness Gauge

It is an Instrument Used to Measure the Thickness of Materials and Objects. We Usually Measure Whether a Thickness of Aluminum Profiles is up to Standard.

Ul94 Horizontal and Vertical Combustion Tester

Ul94 Horizontal and Vertical Burning Test Machine is Used to Test the Flame Retardancy of Our PC Wire Tube. the Test Standard is to Extinguish After Leaving the Open Flame and the Length After Burning Shall not Be Higher Than 20Mm.


IT Refers to an Instrument That Can Quantitatively Express Color Perception Difference. for Example, There are Many Factors in the Production of Our Lamp Caps. Color Deviation May Occur in Batches of Products. Color Deviation Must Be Measured with a Color Difference Meter Frequently in Production to Adjust the Production Process to Achieve Product Color Consistency.

Fat Dissolving Index Tester

Used to Test a Melting Point of Products Made of PC Materials Because Each Batch of PC Materials May Have Different Melting Points, It is Convenient for Our Operators to Set the Melting Point Temperature for Heating.

Cantilever Impact Testing Machine

Used to Test a Toughness of Our PC Material If the Test Material is Hit by a Hammer Falling from a High Place, It is Proved That the Toughness of the Material is Qualified If It is not Broken.

Muffle Furnace Tester

It is Used to Test the Granulated Material Because Some Other Ingredients Will Be Added to the Granulated Material too Many Ingredients Added Will Affect the Toughness and Light Transmission of PC Materials. Generally, We Will First Weigh the Primary Color of the Test Sample, Put It in This Small Cup, and Put It into the Muffle Furnace for Repeated Heating at 900 ℃ Until the Temperature Test is Completed. Take Out the Crucible from the Furnace, and Put It in the Air for Cooling for About 5 Minutes. Put It in a Dryer for Cooling. the Weight Before and After the Weighing Test Cannot Exceed 0.4 Mg.

Through a Series of Professional Instrument Tests, We Will Obtain a Lot of Data About the Lampshade. When These Data Meet the Requirements of Our Customers, We Can Put Them into Production in Large Quantities. After the Lampshade Production is Completed, We Will Enter the Packaging Department.


Then We Will Conduct a Series of Nanny Inspections to Check Whether the Appearance of the Lampshade is Undamaged, Clean, Cut, Flat and Burr Free, Soot Blowing the Appearance of the Lampshade and Assembling the LED Cover.

Finally, Pack and Seal the Lampshades That Meet the Shipping Standards in Corresponding Quantities.

optimize our products and services

In Terms of Price, We Will not Reduce the Cost Invested in Each Link to Fight a Price War. Instead, We Will Keep Improving and Invest More Manpower and Material Resources to Continue to Optimize Our Products and Services

Low Price Products are not Necessarily Cost-Effective Products.It May Also Cause a Lot of After-Sales Problems.Spend Reasonable Money to Meet Customer Needs While Providing You with a Lampshade Aluminum Profile Supply Chain with Stable Production, Stable Quality and Stable Efficiency.
