Adjustable Pressure Boxes

Adjustable Pressure Boxes: J&R has taken their extensive custom thermoforming background, diagnosed the problem areas, and through experience and impeccable design created quite possibly the strongest, precisely engineered adjustable pressure box available today.

Our boxes are manufactured out of the toughest aluminums with ultimate strengths equivalent to steel. All fastener holes contain stainless steel helicoil inserts to ensure durability and longevity. The front panel is adjustable in 1" increments over the customers desired range of indexes. Also, the front and real panels contain v-groove channels to accept the sheet clamp bars providing a tight grip on the material before forming.

Other standard features include a gauge that measures forming pressure, silicone rubber "O" cord seal, and a pressure relief valve to guarantee safety during operation.
