There are two variations: continuous or intermittent. On the one hand, the continuous variant involves constantly feeding the parison to mold and cutting it off with a blade on cooling. On the other hand, intermittent variant expels the molded part before inserting a new parison. As a result, the intermittent variant is less expensive and takes less time.
This combines injection and blows molding processes to make a plastic part. The process starts with making a solid pre-form using injection molding. Afterward, a machine heats the pre-form and blows air into it.
The most distinctive difference between the blow and injection molding is that the former is suitable for hollow parts, and the latter is applicable for making solid parts. Injection molding is the right method for making plastic parts that need a rigid wall, such as bottle caps, hair combs, and computer housings. In contrast, blow molding is suitable for making hollow products with flexible or structural properties. For example, bottles, coolers, fuel tanks, and stadium seats.
