Mold clamps (also mould clamps) are clamping elements with a hole or an elongated hole for the mechanical fixation of various solid bodies on a work plate or holder. Mostly mold clamps are used for plastic injection molding machines and CNC machines.

1.       Mold clamps construction:
Mold clamps are made of long lasting through-hardened steel.
More durable than less expensive, case-hardened clamps.
Styles include Open End, Closed End, Socket and Oversize Hex Bolt.
Easy to install and adjustable—no spacers are required.
Washers are extra-large and made of hardened steel.

2.       The mold clamps mounting ways:
One end of the mold clamp rests on the body to be tensioned, while the other end rests on a base. The screw attached as close as possible to the workpiece is fastened at the lower end in a plate, measuring or machine table equipped with T-slots or holes. In most cases, the clamping force is applied by firmly tightening a nut. A faster change of workpieces enables lever-operated eccentrics attached to the screw. Hydraulic systems in connection with separate mold clamps are rather rare because automated operation is not possible.
