KOR-LOK locking hydraulic slide by PFA

Locking hydraulic cylinders are used when undercuts occur in the cavity side of the tool. This is a situation that the savvy part designer will avoid if at all possible. Locking cylinders have a self contained locking mechanism that helps the cylinder hold against molding pressure. They are rated by pounds of holding pressure. This is calculated by multiplying the projected molding area on the slide by 10,000 psi. If you must have cavity side undercuts that require a locking cylinder, specify KOR-LOK by PFA ( www.pfa-inc.com ). They are the most compact and dependable locking cylinders available. PFA is also capable of locking against greater forces than other cylinders available.
