Molding flash

Molding flash is excess material attached to a molded product, which must usually be removed. This is typically caused by leakage of the material between the two surfaces of a mold. (This leak begins along what is called a parting line in mold design.^{[citation needed]}) Molding flash is seen when the optimized parameter on cull height is not calibrated.
