    Alignment Locks

    Precisely align and lock together your mold halves, so they stay in place during high-pressure injection molding. They're used as the final alignment between your mold halves, after leader pins and bushings (not included) guide your mold halves close together.

    Tapered round locks prevent sliding in all directions unlike top and side locks, which only prevent sliding in one direction. Install them where the two halves of the mold meet, often called the parting line. You’ll need to machine pockets in each half of your mold separately, so you’ll need to take extra care to make sure the two pockets are aligned. For a complete pair, you’ll need a male and female lock with matching ODs. The height does not need to match.

    The tapered shaft of these pins eliminates the need for hammering and prying when aligning flange bolt holes. To align bolt holes, fit the tapered end of the pin into the bolt holes and use a wrench on the hex head to rotate and align the holes. If your bolt hole is in between the sizes listed, choose the smaller size pin.

    Diamond Head

    A slightly undersized shank makes these pins easy to install and replace. Also known as slip-fit and lock-screw locating pins, they are held in place by a lock screw (sold separately). Mate pins with holes in workpieces for precise alignment. The shoulder provides a consistent height reference point.
    Diamond Head—Diamond-head pins make less contact with the inside of a hole than round-head pins to reduce sticking and jamming.

    Round Head

    Diamond Head

    The shoulder provides a consistent height reference point and keeps the pin from being pressed through the fixture. Install these pins in a plate or table and mate with holes in a workpiece for precise alignment. Press the shank into a drilled hole for permanent installation.
    Diamond Head—Diamond-head pins make less contact with the inside of a hole than round-head pins to reduce sticking and jamming.
