Injection pressure affects the level of detail achievable and the minimum wall thickness of your products: higher pressure allows finer details and thinner walls.
For reference, the standard Precious Plastic Injection Machine v3 operates at 44 bar. You can see an example of how injection pressure is used in practice in this Academy article.
The maximum volume of plastic this machine can inject in a single shot.
