A compression moulding machine comprises: an extrusion unit configured to extrude a rod of pasty polymeric material; a cutting element, configured to portion the rod into individual charges; a rotary carousel, including a plurality of moulds, each mould being configured to receive a respective charge and to form a corresponding object from the charge; a feeder, configured to convey each charge to a respective mould at a feed position; an inspecting device, configured to capture inspection data, representing a composition of the rod or of the charges.

Disclosed are a gradient resin, a preparation method therefor and the use thereof. The gradient resin of the present application is formed by fusing different layers with color transition changes, wherein the color transition change between the two adjacent layers is in the range of 0.1% to 5 20%. The gradient resin is composed of, by mass percentage, 98%-99.99% of a resin powder and 0.01%-2% of a pigment.

A punch pin hole inspection apparatus and method uses a punch and a die capable of checking defects or damage, specifically pin holes or microcracks, due to shaping immediately after finishing shaping a laminate sheet into a battery case using the punch.
