Which feature is commonly found in injection moulded products?

Injection moulded products typically exhibit mould split lines, which are the lines formed where two halves of the mould come together to create the shape of the object. This is an integral aspect of the moulding process, as it allows the molten plastic to fill the cavity of the mould and be shaped into the desired form. The split line is an essential feature in the design of the mould, ensuring that the product can be easily demoulded after cooling.

Mould split lines can often be strategically placed in areas that are less visible or can be designed to align with other aesthetic features of the product. Understanding the presence of mould split lines helps in the design considerations for aesthetics and functionality in injection-moulded items.

On the other hand, features like visible seams, textured finishes, and surface coatings may occur in some cases but are not inherent to the injection moulding process itself. Visible seams arise from the joining of materials rather than the moulding process, textured finishes require additional mould designs or treatments not standard in all injection mould products, and surface coatings are applied post-production to achieve specific looks or protective qualities rather than being a direct result of the injection moulding method itself.
