LMG 500-TON HYDRAULIC COMPRESSION PRESS

Model: 500HD3724841 | Serial: 18829

GENERAL DESCRIPTION

Heavy-duty LMG (Lawton/Trinks lineage) hydraulic compression press

designed for high-force industrial molding applications. This unit was

previously utilized in the production of recycled plastic pallets and is built

for continuous-duty operation with large-format molds.

The press features a robust frame, large platen area, and a properly sized

hydraulic system delivering both high force and practical cycle speeds for

production environments.
