SPC Flooring Quality Test From Raw Material to Shipping
Quality control in SPC flooring production follows a step by step process from raw materials to container loading. Each stage catches different potential issues. Here is how a well run factory checks quality at every stage.
Step 1 Raw Material Check
Before production starts, the factory checks the raw materials. The print film known as decor film is checked against the reference sample. The factory compares the color to the approved standard. If there is any color difference the batch is not used.
The limestone powder is tested for moisture content. If the moisture level is too high the material will not extrude properly. The powder must be dry enough to mix evenly with the PVC resin.
Step 2 During Extrusion Line Monitoring
As the planks come out of the extruder, the production line operator monitors continuously. Thickness is checked at multiple points across the plank width. Squareness is verified to ensure the plank has proper right angles.
The surface is inspected for defects. The operator looks for scratches, bubbles, dull spots, and print film wrinkling. Any defective section is marked with a grease pen. These marks are visible at the next stage so the defective planks can be removed before packaging.
Step 3 After Profiling Laboratory Testing
After the planks are cut to size and the locking mechanism is profiled, samples go to the lab for testing. The lab checks:
- Thickness at multiple points
- Squareness of the cut edges
- Gloss level on the surface
- Locking mechanism pull strength
- Peel strength between layers
- Shrinkage and curl rate using oven test data
- Surface scratch resistance
- Wear layer abrasion resistance
These lab tests confirm the production batch meets the product specification. If any test fails the batch is held for review.
Step 4 Before Packaging Surface Inspection
Before the planks are packed, a final surface inspection is done. Each plank is checked for visible defects. Dust and debris are cleaned from the surface. Short planks and end pieces are separated.
The correct label is applied to each bundle. The label shows the product code, color name, batch number, and quantity. Labels are checked for accuracy.
Step 5 Packaging
Planks are stacked in correct orientation and packed into cartons. Each carton is sealed with tape. The cartons are stacked on pallets.
Corner protectors are added to each pallet. The pallet is secured with strapping bands. Stretch wrap is applied around the entire pallet to protect against dust and moisture during shipping.
Step 6 Before Container Loading Final Check
Before the container is loaded, the factory checks the shipping marks. The mark label on each carton is verified against the packing list. The correct destination port, buyer name, and product code must match.
Photos and videos are taken of the loaded pallets. These records confirm the condition before shipping. Air bags are placed in the gaps between pallets inside the container. This prevents the pallets from shifting during ocean transit.
The container is sealed and the shipping documents are prepared.
