Why Weld Seam Flattening is Crucial Before Polishing Refrigerator Liner Shells
When manufacturing high-quality refrigerator liner shells, stainless steel welding is a critical step. However, the intense heat from the welding process inevitably causes the stainless steel to warp, leading to an uneven and distorted weld seam.
If you skip straight to the polishing phase without addressing this unevenness, the final aesthetic and structural results will be heavily compromised. That is exactly where our Hydraulic Refrigerator Liner Weld Seam Flattening Machine comes into play.
Stainless steel is highly sensitive to heat. During the seam welding of refrigerator liners, thermal expansion and contraction leave the weld zone bumpy and irregular. Attempting to grind or polish an uneven seam directly often results in:
Inconsistent finishing: Excessive material removal in some spots and skipped areas in others.
Aesthetic defects: Visible warping that ruins the premium look of the appliance.
Increased tool wear: Faster degradation of grinding wheels and polishing belts.
To solve this pain point, our specialized flattening machine utilizes robust hydraulic power to roll and compress the weld seam before any polishing takes place.
By running the welded liner through the heavy-duty rollers just once, the machine effectively flattens the raised weld bead and relieves the internal thermal stress of the metal.
