WebbTo support good filling of the part, minimum wall thickness should be 8 mm (Note smaller wall thicknesses around 3-4 mm are achievable and depend on bead size, wall height to width ratio and manufacturing parameters). See additional detail below. Please note that most of the current UL 94 material listings require a minimum wall thickness of 8 mm. Webb13 dec. 2024 · Otherwise, the plastic parts will be deformed due to uneven shrinkage, which will affect the strength of plastic parts and the fluidity during injection molding. Thickness difference shall be controlled within 25% between each wall, and the minimum wall thickness of the part shall not be less than 0.4mm, and the area shall not be … Webb6 maj 2024 · The thickness of the rib where it intersects the wall should be 50% – 60% of the wall thickness, with a fillet radius of 0.015 inches (0.381 mm). The maximum height of the rib is 3x the wall thickness. The typical draft of a rib is 1° to 1.5°, with a minimum of 1/2° per side. The minimum spacing between the ribs is twice the wall thickness. … pachymetry test normal range
