Used Van Dorn Injection Molding Machines

On nearly every Van Dorn KD Machinery has listed, the first number in the model is the clamp tonnage, so a 300HT is a 300-ton press. As of October 2026, every used Van Dorn on its record was built between 1994 and 2007, and most are HT presses from 85 to 650 tons.

What the model number says

The tonnage rule holds from the small presses up, so a 170HT is a 170-ton press. What follows the letters varies. On some machines it is the shot size in ounces, so a 300HT-30 is listed with a 30-ounce shot and an 85HT5 with 5 ounces. On others it is a four-digit code: the 230HT and 300HT machines with 1220 after the name are listed with a 25.4-ounce shot, and the 500HT and 650HT machines with 4300 at about 89 ounces. When in doubt, read the shot size on the listing.

Larger Van Dorn presses

Above the HT range, KD Machinery’s record includes HP machines from 700 to 2,000 tons, Spectra machines from 500 to 880 tons, and Caliber and Titan presses from 730 tons up to 2,200. Some listings name the make as Van Dorn Demag, and a few carry an NC4 or NC5 control in place of a Pathfinder.

Pathfinder controls

Most Van Dorns on KD Machinery’s record run a Pathfinder control. The Pathfinder 2500 appears on machines from 1994 to 1997, the 3000 from 1995 to 2007 and the 5000 from 1998 to 2006. Ask whether the control has been serviced and whether spare boards come with the press.

What to check on a press this age

The Van Dorns on the record are close to twenty years old or more, so condition matters more than model. Ask to see it under power, which most of these listings offer. Check the hydraulic oil, filters, hoses and pump for leaks and noise, and the screw, barrel and heater bands for wear. Cycle the clamp and check the platens close square; on a 300-ton machine they are 37 inches square with 25 inches between the tie bars. Confirm the core pulls and hydraulic knockout, which most machines on the record have, work as they should.
