Understanding Key Differences in Plastic Manufacturing Processes
It is imperative to note that injection molding and the compression molding are two common processes in plastic manufacturing, though varied greatly in their application. Injection molding has a particular advantage when it comes to the large production volumes of intricate parts with good surface finish, with the use of automation and repeatability. However, low pressure compression molding is especially suited for large parts, high reinforcement fractions, and small production volume and simple tooling.
In fact, the two do not subsume each other as systems but can be viewed as two different methods available for manufacturing. Superalloys have certain applications depending on the production rates, geometric complexity of the component, requirement of specific material, tolerance limit and cost constraints.
