GENMAX manufactures mattress spring machines that cover the two core steps of innerspring production: coiling steel wire into individual bonnell springs, and assembling those springs into complete spring units with helical wires. Together, the YHJ coiling machine and CWJ assembling machine form a compact bonnell spring production unit that one or two operators can run.
