| Powder Compaction Press for Very Small-Size or Thin Parts |
| Multipak Anvil-Type Press (Pentronix) |
|
|
Anvil pressing, pioneered and developed by Pentronix, is a simple, easy-to-use, high-speed, and high volume powder compacting method.
Anvil pressing requires that one side (anvil side) of the molded part be flat. Since most molded parts meet this requirement, anvil pressing can be used in a wide range of parts production. Due to its mechanical simplicity and durability, the anvil presses offer special user benefits. For example, anvil-type presses produce high-precision parts, continuously at high speeds, with no operator required. Because dies do not require upper punches, initial costs can be reduced by 25% and running costs can be decreased by more than 50%. |

- Although in conventional (general) presses parts are compacted between opposing upper and lower punches, in anvil-type presses parts are compacted between an anvil and lower punches.
- The anvil is fixed on the die surface and powder is compacted into parts against the anvil by the upward motion of lower punches.
- Because there is no upper punch insertion, breakage and wear of the dies, due to setup problems can be eliminated.
- The die's set up is easy, and special skills are not required.
