Industries & Applications
Hydraulic presses are commonly used for forging, clinching, moulding, blanking, punching, deep drawing, and metal forming operations. The hydraulic press is advantageous in manufacturing, it gives the ability to create more intricate shapes and can be economical with materials.
- Assembly – Fastening two or more parts together with a hydraulic assembly press.
- Ex: Bearings, shafts, electrical switches, water pumps, rear axle assembly, munitions assembly, windshield wiper blades, fuel injection sensors, gear assemblies, medical instrument assembly
- Compaction – An object produced by the compression of powdered material, typically done with a custom hydraulic compaction press
Ex: Powder make-up compacts, Teflon powder for seals, munition fuse assembly, fuel cell compaction, battery compaction, clutch friction material bonding, hot molding.
- Deep draw – The deep drawing process is a metal forming process that occurs under a combination of tensile and compressive conditions using a compression press. To be considered deep drawn, the height of the case is usually at least two times the diameter.
Ex: Fire extinguishers, oil cans, fan housings, aerospace ductwork
- Coining – A squeezing operation, usually performed cold in a closed die, in which the metal is forced to flow to fill the shape and profile of the dies. Due to the high tonnage requirements of a cold working process, customized hydraulic presses are preferred for this application.
Ex: Resizing powdered metal parts, high voltage power lugs
- Forming – change the shape of a metal piece and does not intentionally reduce the metal thickness.
Ex: Journal bearing for locomotives, electrical housings, medical battery or device cases, appliances including dishwashers, ranges, refrigerators, as well as stamped and formed panels for these items, flattening exhaust systems for mounting, windshield wiper blades, HVAC parts, jewelry (rings and settings)
- Embossing – A process, using a custom hydraulic press, that creates imprinted designs in sheet material by means of male and female dies, theoretically with no change in metal thickness.
Ex: Lettering, structural stiffening of sheet metal parts
- Piercing – Cutting or punching an opening, such as a hole in sheet material, plate or various parts with a hydraulic c-frame floor press.
Ex: Automotive exhaust systems, High Power electrical connectors
- Stamping – A general term that describes taking a flat piece of material and using a die and a hydraulic floor press to transform its shape.
Ex: Perforated metal, stamping battery substrates, or any shape in metal, plastic, foam or other materials
- Trimming – Typically a secondary cutting or shearing operation on a previously formed, drawn, or forged part. The goal is to “trim” any surplus metal off of the edges, bringing the part to the desired shape and size.
Ex: Automotive dashboards & carpets, dishwasher baskets, die-cast trimming, truck body panels, plastic parts
- Press fitting – Assembling parts with an interference fit
- Crimping – an assembly technique that uses a custom assembly press and appropriate tool to fold and flatten material so that two pieces are securely fastened together by a pinching action. This technique is commonly used to join sheet metal parts.
- Staking – A method using a custom assembly press to permanently fasten two pieces or parts together by recessing one piece within the other and causing plastic flow of the material at the joint.
