The feed material must be supplied under sufficient pressure to ensure a stable, continuous flow into the gap between the rollers, thereby forming a d

Roll forming is a cold-forming process that utilizes the plastic deformation characteristics of materials to shape complex components through the roll

Roll forming is an advanced sheet metal forming process characterized by material savings, energy efficiency, and high productivity.

The roll forming production line primarily consists of equipment such as an uncoiler, butt welder, forming unit, wheel welder, cutting machine, and co

The basic principle of roll forming involves passing metal strip through a series of sequentially arranged forming rolls to induce continuous, increme

"Induced voltage" on an appliance casing generally refers to an electric field generated on the surface of an appliance—which is neither grounded nor

The gray appliance casing is designed for grounding purposes.

Generally, only appliances with metal casings require a ground wire; casings made of other materials do not.

Grounding the casing of an electrical appliance prevents the risk of electric shock caused by current leakage and helps reduce electromagnetic radiati

The strength and corrosion resistance of an appliance's housing material are critical factors affecting its lifespan and safety. In these respects, me

Performance requirements encompass mechanical strength, impact resistance, rigidity, and weight.

Issues such as damaged insulation or aging wiring inside the appliance can cause current to leak onto the casing.
