What is the 5 types of mold level of SPI classifications and standards?

When you want to make an injection mold tooling to produce your plastic parts or components, determining if the product is suitable for a streamlined injection molding process is one of the first steps.
The experienced injection mold engineers will ask a series of questions to better understand your project requests,from the part design, part market purpose and objectives surface requirements– to first determine overall mold making progress, and then to confirm what type of mold is best suited for the job. Using mold classifications to determine the correct mold type is crucial to achieving quality, production and cost objectives.
Standard the mold toolings are defined by the Plastics Industry Association (formerly known as the Society of Plastics Industry or SPI). These mold standards are categorized into five classifications to guide quotes and orders into uniform mold types as below:
