In House Testing Lab
to Ensure Your Top Quality
In addition to the process inspection in the production process, we also carry out appearance and color inspection, fatigue test, mechanical performance test, sweat corrosion test, spectrum and scratch wear and other inspection tests, pursuing 0.1mm processing accuracy and pursuing perfect quality.test, sweat corrosion test, spectrum and scratch wear and other inspection tests, pursuing 0.1mm processing accuracy and pursuing perfect quality.
Radnor Quality Control Process
Step 1: Strict IQA
Radnor's strict IQA ensures all the raw materials are conducted fairly.Making sure all of the accessories are qualified and matched our requirement
Step2:Metal Soldering QC
Radnor's metal soldering process is quite different from another factory. Soldering of Bridge, temple, lock,etc by stable mold.QC has to ensure each part is made according to specific requirements.QC has to ensure each part is made according to specific requirements.
Step3: After Polishing QC
According to Radnor's inner requirements of the color range of the surface, after polishing, each part of the frames has to be classified and inspected strictly.
Step4: Metal Plating QC
Metal plating, color praying are made by Radnor's inner workshop, there is a total of 10 aspects are need to be inspected for each frame.
Step5: Asembling QC
The high handmade process of eyewear frames causes the difficulty of assembling. We have 5 QC placed here to ensure each frame have been assembled perfectly.
100% Inspecting of All Incoming Materials
Strict QA is the key to offer qualified products to all of our customers. In regards to metal parts,we inspect the appearance by vision, touching, and reference samples. The measurement inspection is done by international vernier calliper. Testing the toughness of the material with destructive bending. The brightness of the material is inspected after polishing.
100% Inspection of Each Half-soldered Metal Frames
The metal acessories with Indentations,scratches,touch surface are rejected. The measurement tollerence controlled within 0.15mm. Same time, curve of the metal temple, tips taper, as well as the drilling position are strictly inspected. Each soldering process is done by specific soldering stable mold. Each mold is exclusive for our clients.
100% Inspection of After Polishing Frames
Most of the inspection of soldering is done by version. At this process,we will ensure no scratches, shift spots, dents on the surface. The surface is bright and the solder joints are smooth. The screws must not be scratched, and the pattern is clearly engraved. The sanded part is accurate, uniform and non-boundary, and cannot be blasted insufficient or polished off. The screws must not be flowered, and the pattern is clearly engraved.
100% Inspection of After Trembled Acetate Frames
In addition to the process inspection in the production process, we also carry out appearance and color inspection, fatigue test, mechanical performance test, sweat corrosion test, spectrum and scratch wear and other inspection tests, pursuing 0.1mm processing accuracy and pursuing perfect quality. Test, sweat corrosion test, spectrum and scratch wear and other inspection tests, pursuing 0.1mm processing accuracy and pursuing perfect quality.
100% Inspecting of All Plated Metal Parts
Adhesion inspection is most important for plated metal parts. Tools of magnifying glass,strong adhesive paper,and sharp edge lens are used for this process of inspection. Fisical version still place an importance role as well. The other points such as color difference,solubility resistance,grain,oxidation,color degree,thicknes,coating, and color difference are needed to inspected very carefully too.
100% Inspecting of Each Assembled Frames
This is the last key inspection which enable us to offer our clients qualified goods with right packages, print information, and perfect matching. All accessories are brought to here to go to their specific place. Measurement,structures,and physical property testing will be made again. Customized logo and packages are inspected one by one before put them in to paperboard carton.
