WebAcrylic is a lightweight, shatter-resistant plastic also known as plexiglass. Since it is transparent and can withstand weathering effects like sunlight, heat, and rain, manufacturers often use acrylic as an alternative to glass. However, it is not good for bearing too much weight. Also, grease or oils can stain acrylic easily. WebOct 10, 2024 · Flow rate — the rate at which a material moves or flows into a mold — is partially dependent on material composition and will make a difference in the manufacturing process. Because pressure is required for the injection molding process, thin wall areas in a mold can cause material flow rate issues no matter what material is chosen.
