What methods prevent warping in thin-walled PVC animal sculptures?
Warping in thin-walled PVC animal sculptures can be frustrating, but several methods can help maintain their shape and durability. First, ensure proper material selection by using high-quality PVC with additives like stabilizers to resist deformation. Second, control the cooling process after heating or molding—gradual cooling reduces internal stresses that cause warping. Third, reinforce the structure with internal supports or armatures, especially for larger sculptures. Fourth, avoid excessive heat exposure during crafting or display, as PVC is sensitive to temperature fluctuations. Finally, apply a protective coating or sealant to shield the sculpture from environmental factors. These techniques will help preserve the integrity of your PVC animal sculptures.
