The top platen is capable of handling a tool weight of 600 lbs.

The bottom platen is capable of handling a tool weight of 600 lbs.

1.2 10" sheet sag clearance.

2. DEPTH OF DRAW:
2.1 12" below sheet line, 12" above sheet line.

The top platen has a 28" maximum stroke.
The bottom platen has a 22" maximum stroke.

C. SPECIFICATIONS:

1. MAXIMUM SHEET SIZE:
1.1 Add 2" (50mm) to width and length of mold size.

2. CLAMP FRAME:
2.1 The clamp bars are operated by lock-over-center compound, toggle action air cylinders mounted on 18" centers.

The clamp frame bolts to the car and has color coded, quick disconnects on the incoming air lines, adjacent to the frame.

The long dimension frame and bars are adjustable front to back in the short dimension frame. To change the long dimension requires replacement with the desired length frame section and bar.

The clamp bar has spring loaded pins in the gripping edge on 2" centers for gripping the sheet.

2.2 The clamp frame has eight (8) clamp cylinders.

2.3 The clamp frame is arranged for top loading.

3. OVEN:
3.1 The lower bank is manually adjustable vertically to compensate for different sheet sag characteristics.

The lower bank is equipped with a safety screen.

3.3 The top and bottom heater banks are fitted with infrared, electric, ceramic heating elements. The elements are 4.7" x 4.7", 400W.

Zones 1 & 4 - Twenty-two (22) heating elements each zone outer ring.

Zones 2 & 5 - Fourteen (14) heating elements each zone inside ring.

Zones 3 & 6 - Six (6) heating elements each zone center area.

All of the above elements have a flat surface.

See attached layout.

3.4 IR head positioned in the center of the top oven. Display is mounted in the enclosure door.

5. OVEN AIR JET SYSTEM:
5.1 The manually actuated (from the load/unload area) air jet system in the lower bank of the oven simultaneously shuts off the oven heaters and activates the air jet.

6. FORMING STATION:
6.1 The form station has top and bottom platens that are actuated by two-speed electric motors.

Each platen speed and stroke is controlled by adjustable position limit switches.

The limit switches are accessible by the operator from the front of the form station.

Each platen has a multi-point gear rack/torsion shaft guiding to provide parallelism and stability.

The top platen will be chain driven to front and back drive shafts.

The bottom platen will be driven thru gear boxes to the drive shafts.

Each drive shaft has a disc brake to hold the platens during pressure forming.

7. COOLING FANS:
7.1 One (1) 1/4 HP, 16" diameter, high volume fans on adjustable position mounts. Fan is located above the form area on the inboard side.
