About Our Business
JBM Industries started in 1978 making reproduction rubber and machined parts for vintage
automotive hydraulic systems.
JBM is unique in that we offer both design, development, and manufacturing of many hard to find or
obsolete mechanical or rubber parts.
Being small offers us flexibility and the ability to offer attention to detail. We solve problems here.
JBM strives to make better quality parts. We are not always cheaper, but in many cases we are both
cheaper and better than other manufacturers. We design and build our own tooling, or can run your
tooling in our shop.

Shown here is a recent project restoring a very old
rubber press. This press will push 80 ton, has a 10 inch
ram, and can be disassembled easily.
This project involved conversion to electric heat from
steam. It also had to have a hydraulic power supply and
complete automatic control system as well as loading
table and extra daylight spacers.

This project involved conversion to electric heat from

This press runs at 240 volts with 6000 watts heating capacity. 5 hp single phase motor powers the hydraulic mule.
Split spacer bushings clamped over the post threads allow an 8 inch increase in daylight. This press runs insertion molds.
Hydraulic accumulator is used to maintain pressure when motor is off. Adjustable hydraulic pressure switch controls the pump
motor. We have converted 7 presses in this manner.

Rubber molding begins by heating the mold in the press for about 1 hour. The mold is then opened and mold
release is sprayed into the mold. Uncured rubber is cut to size and weighed.
The mold is placed in the press and held closed while heat is maintained for 15 to 30 minutes depending on the
part. Heat cures the rubber. Mold is then opened and parts removed.
Parts must be trimmed of flash with scissors.
