It is allowed to cure before being demolded carefully. You will find a thin-bodied cast that is an exact replica of the original model, down to every tiny nook and crevice. Other casting methods fail to achieve such a high level of precision. The demolded piece does not need to be cleaned or finished much either. However, models with large undercuts cannot be replicated with injection molding. Injection molding is a commonly-used manufacturing process for producing thin-walled parts with great accuracy. It is generally used to make small plastic, metal and even glass items. Model parts for miniature cars, trains and complicated superhero figures are made with the injection molding process. It will yield accurate copies very quickly and in large numbers too. The manufacturing process involves feeding the casting material into a machine which crushed it to a liquid state before injecting the same into the mold under high pressure. This mechanical process is repeated again and again to make multiple copies. The plastic in the mold is allowed to cool before being ejected from the mold.
