Moulds
We manufacture Entry and Mirror type of Moulds for a wide rage of
presses. A typical Mould is shown here and mainly consists
of the following parts:
|
 |
A. Base Plate
This constitutes an extremely flat surface between
the mobile section of the die and the press bench so as to ensure
flatness and rigidity of the die.
B. Rise Block / Ejector
The risor block consists of a block, on the top
part which are fixed magnetic punch holders, to which the punches
are rigidly attached. The purpose of the block is to ensure that
the lower punches move together during expulsion and during loading,
when the punches lower to create the space for powder filling. It
helps to discharge the pressing force as well.

C. Die Box /
Matrix and Liners
The die box is essentially a frame manufactured
from a plate with good bending strength. It is fitted internally
with liners which consititute the most important part of the die
box as these contain the powder to be pressed and provide support.
These are made of high-quality alloy steel and are hardened to a
hardness of 60-62 Rc. The tapered shape facilitates de-aeration
during pressing, extraction of the tile and constitutes a guide
for the upper punches when they enter the die cavity.
D. Upper / Lower Punches
The punches are manufactured from hardened steel
or toughened steel with wear resistant material added to the edges.
The punches are milled and ground to obtain the exactly the right
profile of the tile edge, and finally covered with a layer of special
vulcanized rubber.
The rubber coating helps prevent the powder from sticking to the
punch surface and ensures better pressure distribution on the surface
of the powders. The tile production increases substantially, as
there is no necessity to clean the punches. |
