In the less material shrinkage and not affect the aesthetics, then can a little thicker. However, should consider when designing for this easy brought to the dents on the surface opposite the latest tendons. -Tendon thickness also affects the priority flow in the extrusion process-the cause brought to the welding line defects and pitting. The tendon should parallel design, the distance between the tendons should at least equal to 2 times the thickness → help reduce cooling system and exhaust tracks within the The tendons should be placed along a direction to achieve solid hardness. Can put horizontal but this does not bring high efficiency by placed along the
