Page 16: Gauge Information
RAM FORCE CALCULATION All CARVER gauges are calibrated for the specific ram diameter of the hydraulic unit. The Mini "C" and Model "C" 12-ton (107Kn) ram is 3.294 square inches (21.253 square cm) and the Model "M" 25-ton (223 Kn) ram area is 5.157 square inches (33.273 square cm).
Page 17: Filling The Oil Reservoir
FILLING THE OIL RESERVOIR The hydraulic unit is filled with oil at CARVER, INC. and should not require additional oil. In the event there is some oil loss, lower the platen, remove the sintered breather plug, and fill with oil up to the level of the filler hole on 12 & 25 (107 &...
Page 18 The outlet manifold must be plumbed downward to drain the platens properly. If the manifold is plumbed upward, CARVER, INC. recommends the use of a check valve to eliminate backflow into the platens and a pump to recirculate the drain water.
Page 19: Section Four
Always check the pressure rating of the pressed apparatus prior to pressing to be sure it is rated for the applied pressure. IMPORTANT: The gauge on the CARVER laboratory press shows the total force exerted by the press. It DOES NOT show the pressure on the specimen (PSI/BAR). To find the PRESSURE (P) on the specimen, the observed FORCE (F) reading on the gauge must be divided by the specimen AREA (A), per the equation P = F/A.
Page 20: Operating The Hydraulic Press
Please keep in mind that no hydraulic unit will maintain constant pressure without some additional pumping. This is especially true when pressing against a soft or yielding material. Some pumping is required to offset normal packing leakage. After the desired pressure is obtained, an occasional stroke or two will normally maintain the pressure. Carver Inc...

Page 24: Laminating Presses
LAMINATING PRESSES Introduction We are pleased to provide a CARVER Laminating Press for your operations. Although this equipment is a standard apparatus for general laminating work, these presses have wide use for other applications where heating and chilling under pressure is required. Many of these presses are in daily use by the Armed Forces, Government Agencies, Universities and Industry for important jobs where securities, ease of operation and quality production are essential.
Page 25 Each press is supplied with one pint (.47 liters) of Special Hydraulic Oil #2170, but this should only be needed if there has been some visible loss. Keep this bottle sealed from dirt and dust. We advise using only CARVER Hydraulic Fluid or those recommended as substitutes earlier in this manual.

Page 28 This procedure is continued using the thick stack for the next transfer, thereby producing a stack of laminations every six to eight minutes. 4-10 Carver Inc...
Page 29 Often the best results come after a number of trial runs. The CARVER Laminating Press is adjustable for use with any of the thermoplastic materials used laminating. Figures given on the preceding pages for temperature, pressure and time are based on the use of regular plastic sheets, either .010"...
Page 30 It will be readily seen that the two stacks will not have equal pressure per square inch applied to the plastic. 13. Many of the thermoplastic materials on the market may be used with the CARVER Laminating Press such as acetate, vinylite and certain acrylic materials. Pressures, temperatures and time for laminating the various materials will however, be different.
Page 31: Section Five
SECTION FIVE MAINTENANCE Each CARVER Laboratory Press is thoroughly tested to provide trouble-free performance. Manufacturing and assembly processes are closely controlled in our factory under rigid inspection and testing procedures. Follow these instructions, and with proper care, your press should give many years of trouble-free service.

Page 48 AIR BLEEDING Air accumulation in a hydraulic system will cause erratic action. This may appear as pump failure to the inexperienced user. For this reason, it is advisable to air bleed each pump before attempting to operate. To remove air from the pump, open release valve with the pump in an upright position.
Page 49 PUMP PISTON Leakage of oil around the pump piston indicates worn or damaged piston packing. To replace packing: Remove piston actuating linkage. Remove piston. (See piston drawing.) Remove all packing. (See piston drawing.) Clean all parts and dry with compressed air. Install new packing, wipers and static seals, being sure, packing sealing lips, face down toward the pressure.
Page 50 PUMP VALVES If the pump fails to supply pressure or if the pump piston is under pressure at all times, the pump valves may need a cleaning. Stand pump in upright position while removing valve plug and valve seal. Tilt pump to remove valve springs and balls.
Page 51 RELEASE VALVE If the pump fails to lift or hold a load, the release valve may be dirty. From back of pump remove release valve plug, release ball spring and release ball. From front remove release lever pin, release lever, and release plunger. Clean release valve chamber and inspect ball seat.
Page 52 LARGE PISTON PUMP RELIEF VALVE If the pump fails to lift faster under no load than it does under heavy load, the large piston relief valve may be dirty. This valve is covered with sealing compound to prevent tampering with large piston changeover point. Remove sealing compound, relief valve screw, valve spring and relief plunger.
