These two parameters go hand in hand. ๐ค ๐ก A rougher VDI texture increases friction between the plastic part and the mold surface during ejection. Without sufficient draft, this can lead to: ❌ Drag marks ❌ Scratches on the textured surface ❌ Difficult ejection ❌ Increased wear on the mold ๐ฏ As a general rule, the deeper the texture (higher VDI value), the greater the draft angle required to ensure a smooth release and preserve the intended finish. At Star Moldes, we work closely with our customers from the design phase to optimize: ✅ Part aesthetics ✅ Mold manufacturability ✅ Reliable ejection ✅ Long-term production performance Because great plastic parts are not the result o...
