When we buy the products of plastic flower pot manufacturers, we must check its quality, etc. If we find that some products have uneven colors, what is the reason?
Specifically, in the process of producing plastic flower pots, poor diffusion of the colorant is an important reason, which can cause patterns to appear near the gate. Another reason is the poor thermal stability of plastics or colorants. To stabilize the color of plastic flowers, it is necessary to strictly fix the production conditions, especially the material temperature, material quantity and production cycle. The shape and location of the plastic flowerpot have an impact on the filling of the plastic, and it will also cause chromatic aberration in some places.
In addition, for crystalline plastics, the cooling rate of each part should be as consistent as possible. For products with large wall thickness differences, colorants can be used to mask the color difference. If the color of the plastic flowerpot is uneven, it will affect the appearance, so we still have to check it carefully.
