In post-injection molding operations, plastic parts often retain excess sprues (gates) that must be removed before final assembly.

In the assembly of large plastic components—such as housings for household appliances or electric vehicle (EV) charging stations, where part dimensions often exceed 300 mm—it is common to join two shell halves along complex, contoured seams.

In the manufacturing of consumer electronics and industrial control equipment, plastic enclosures often retain residues such as mold release agents, cutting oils, or ambient dust on their surfaces and within intricate internal features after injection molding.
