Function of dry powder press:
25Ton Powder compacting press is a compression molding process used in ceramics, pharmaceuticals,
construction,brick-making and other industries to form complex shapes from metallic, ceramic, composite,
PTFE, and other powder compounds.
the powder pipe and filling shoe automatically, then the upper punch do compacting to shape the powder,
thereby, realize the function of automatic withdrawal, ejection and power filling to the shaped products.
All motions are completed automatically by mechnical powder press.
Shaping principle: lower punch fixed, when the cavity of die filled with powder in filling position, firstly,
upper punch immerses into the cavity of die and do pre-pressing (pre-pressing exhaust) for powder,
then upper punch and die move downward simultaneously and do compressing for power. At this time,
the lower density of green part is higher than upper part, finally, upper punch compress the powder to
the cavity of die and do top pressing. At this time, the density of upper part also become higher, therefore,
realize double-direction function. When die continues to move downward, the green parts eject out from
the die; if the upper punch has a suitable pressure which is constant compacting on the green parts till green
parts ejected out from the die so as to ensure protective withdrawal and avoid cracks caused by product expansion
during ejection, it also called protective withdrawal.

Technology and control of ceramic powder forming machine :
1.realize homogenization of green body
No matter whether it is dry powder pressing or isostatic pressing,
there are internal and external friction
between powderparticles and between powder and mold wall, which leads to uneven density distribution
of green body. Especially in dry powder pressing, in the pressing direction, the pressure decreases exponentially
with the height change, forming a density gradient, which makes it difficult to achieve the consistency of green body
density. Secondly, in order to meet the powder molding characteristics required by press molding, a certain amount
of additives need to be added.Whether they are uniform in each single particle is also an important factor affecting the
homogeneity of the green body.
2. powder metal forming sample:
The factors that affect the density of green compacts are very
complex. Apart from the characteristics of powder
itself, the main factors are the shape and size of green compacts,
the side-to-side area ratio of pressed pieces,
pressing pressure, mold roughness, lubrication conditions, pressing
methods and friction coefficient of powder
movement in the mold, etc. All these play an important role.
Practice has proved that isostatic pressing is superior
to dry powder pressing, and wet isostatic pressing is superior to
dry bag isostatic pressing. Now, the internationally
popular full-automatic dry powder press adopts the crank-connecting
rod mechanism of forced bidirectional
pull-down pressing. products are not simple blanks,
with different thicknesses and even multiple steps. When
special-shaped products are formed, the movement track of
each part of the die in the press is different, and the thickness
of each part is different. According to the molding technology,
the feeding method, the pressing times of the upper and lower dies,
the position of the pressing line and whether the protective
demoulding is adopted should be selected according to the shape of
the workpiece.
