Bolsters and Steel Plate
Bolster plates for Open Back Inclinable, Horning and Gap Frame and Large Press bolsters are manufactured to customer specifications in Lempco's plants. Bolsters for presses in these categories are built from steel.
In addition, Lempco's volume production of die sets and press machinery requires maintenance of large inventories of steel plate, which can be drawn upon for fast delivery of customer orders for stripper plates and riser blocks. Plates can be cut and machined to your exact requirements.
