The Advantages of Cold
Forming
Parch Saz Co. has developed its ability in producing
rivets with cold forming (CF) method and has optimized the production of
some tools which were produced in the past by expensive and slow ways.
CF is a procedure to form metals in high speed and with no shaving.
During this method materials move and take form based on the shape of
segment. The procedure is possible in ordinary temperature so is called
Cold Forming. Today, modern equipments of CF are capable to produce very
complex segments rapidly and with high quality. CF has attentionable
advantages by comparison with shaving methods and has the possibility to
produce strong and cheap segments.

Various Designs:
Above figure represents a cold heading (CH) operation
with three molds and three ramrods. Although the equipments of CH
have been developed during the last years, Parch Saz Co. has
provided various equipments to shape materials in different stages.
These different stages provide the possibility to produce complex
segments by upset or extrude methods. Upset and extrude methods are
very sufficient to control and shape raw materials and multi-stage
molds facilitate this procedure.

High
Production Speed and Monotony:
CF is able to produce 100 times more rapid and accurate
than machining methods. Four segments are shaped at once in a four-stage
machine and each one are in one stage of production. Each pressing
stroke completes one segment and enters another new one into the mold.
The procedure is performed with the speed of 100 segments per minute.
Tolerance:
The tolerance for the diameter of stairs is available
with ±0.05 mm, for the length of stairs with ±0.1 mm and in some cases
with at least ±0.05 mm.

Reduction of
Shavings:
Machining procedure starts with a bar that its diameter
is equal with the thickest machined bar. The total form will be
shaped by machining the bar until diameters become decreased. This
method produces expensive segments and also extra shavings.
Cold heading, on the other hand, starts with a cylinder
segment and raw materials take their shape by a series of molds. The
procedure forms segments during some stages and with no extra
shavings. The volume of total segment is equal with the volume of
primary segment.

Strength:
When a segment is being shaved, metal is cut to
decrease diameter. Shaving metal disturbs its structure and weakens the
segment. One of the advantages of CF is to increase the strength of
segments by changing the formation of molecules and no part will be
removed by shaving.
We wait to hear from you right today to tell you how we
can change your expensive machining segments to economic CF methods.
