Cost efficient tip manufacturing equipment
from Mikron
Tip manufacturing
Mikron Machining Technology’s past is closely linked
to the history of the ball point pen. Since the early
stages of the ballpoint pen, Mikron has developed
machinery to make writing tips and to assemble refills.
As the cost of pens has been reduced over the years,
Mikron has developed more and more productive
machines.
Ballpen tips, whether made from brass, nickel-silver or
stainless steel are efficiently produced on the Mikron
Multistar LX-24 and Multistar LX-12 Writing machines.
Tips can be made automatically from coldformed
blanks or directly from wire stock. Production output
ranges from 80 to 300 finished tips per minute.
Various tips produced on Mikron Multistar transfer systems
Mikron Multistar machines work to the most demanding
tolerances in the industry and are thus ideally suited to
produce not only the ordinary ballpen tips but also
close tolerance rollerball and jel ink tips. In fact, most
of the leading ballpen brands use writing tips made on
Mikron equipment.

Wire cutting machine Mikron TR-42 WRI
The Mikron TR-42 is a machine for the economical and
straight shearing of wire metal.
Cold heading press Mikron RP-32
As a single stroke cold header the Mikron RP-32 is
most suitable for small plain parts working directly
from coil.

Multistar LX-24 Writing
The Multistar LX-24 with 24 work stations and up to
44 working spindles is the guarantor for a smooth
mass production. With the Multistar LX-24 machining
is possible from below and above. Other additional
features are the 24 intermediate stations, which allow
measuring, controlling and cleaning procedures during
the same run.
That way you can quadruplicate your productivity
It is unique! A run produces up to 600 simple workpieces
per minute. Separating the fields of work doubles, triples
or quadruplicates the amount of production at the
same high processing speed.
Factors of success at one glance
• Fastest rotary transfer machine worldwide
• High precision and repeatability
• Simultaneous machining at two sides at each station
• Multiple cycles for extremely high amounts
• Parallel production of two parts
• Load / unload time parallel to the machining process
• Quick and simple tool changes

Multistar LX-12 Writing offers economic high
volume machining at a low investment level.
The Multistar product line, with over 600 machines
sold world wide in the writing instruments field, has
been completed with the model Multistar LX-12 Writing.
This rotary transfer machine is particularly suitable for
the high-speed machining of brass and NiSi tips in a
single working cycle. Compared with today’s traditional
production methods, the Multistar LX-12 Writing will
considerably improve the writing quality of brass and
BNP tips.
The spindles, clamping collets and cutting tools are
interchangeable with the same components used on
the Multistar LX-24, thus stock keeping of spare parts
is reduced and running the Multistar LX-12 Writing is
economic and easy.
IMPI-34
The Mikron IMPI-34 refill assembly machine has proven
to be a highly reliable, easy to operate and extremly
productive refill assembly machine. This machine is
especially suited for economical capillary refills. It assembles
the writing tip to the point, does crimping and plug
assembly. Blind hot stamping is also possible.

Write test machine ATW-10
To guarantee a continuous, premium quality and
outstanding productivity, the very best quality control
and support equipment is a must.
Writing test machine ATW-10
The machine tests simultaneously 10 refills in different
writing angles between 90° and 60° under a load of
80 - 120 gr (0.176 - 0.265 lbs). It assists in investigating
flow character, affinity, lay-down and wear rate at different
writing speeds. Starting abilities, sphericalness of balls,
and other details may be checked. The registering
mechanism allows the reading of the writing distance
in meters. Adjustable paper feed and writing speed
allow most efficient testing.

Cutting tools and aggregates suggested
by Mikron
Precision tools
One of the key elements when producing steel or
brass tips on Mikron’s Multistar machine, are cutting
tools. Mikron has recognized the importance of high
performing tools many years ago and has thus established it’s own in-house tool manufacturing facility. We
are able to provide standard and special cutting tools
from small special production to large volume series all
within the most demanding quality standards. Consult
us for your tooling needs; our specialists are ready to
help you.
