- Offer Profile
- FJ Sintermetal has almost 30
years of experience in manufacturing components in powder metal Many
components can be manufactured by using powder metal technology. Powder
metal technology is often less expensive and has very high dimensional
precision. Process waste and process time are very low driving down costs.
Tool costs are to be considered, but depending on the complexity of the
component , it is often beneficial to choose powder metal, even if you only
have a few thousand components in annual volume.
- An efficient metal working technology that reduces total manufacturing costs by applying unique powder metal materials and innovative processes into creative designs and geometries. A combination that is hard for competing processes to match. FJ Sintermetal has almost 30 years of experience in manufacturing of powder metal components.
- Actuators are typically driven by a gear motor or
servomotor for determining velocity and position. FJ Sintermetal
manufactures sintered components for linear actuators that are part of the
rotating gear / planetary gears and piston rod / cylinder devices.
In this context, sintered components excelles by having a noise reducing
- Powder metal is a suitable manufacturing method for
machine components and automation. Bushings and wear parts are typically
made of bronze and the filters are often of bronze or stainless steel.
Examples of applications are numerous and the driving force is often price
in relation to the design optimization and precision. Sintered components
often turn out as a cost saving and efficient process compared to
conventional machining methods.
Oil impregnation is often used in bearings and bushings as a
- FJ Sintermetal manufactures sintered components for the
automotive industry. These components are generally characterized by high
quality standards and requirements for capability higher than 1.67 is
typically a necessity. FJ Sintermetal controls the entire process according
to TS 16949 with APQP and PPAP as essentiel elements. The powder metal
technology is an obvious process technology for manufacturing large batches
of uniform quality with specific accuracy requirements and material
- Components for compressors typically have particular high
precision requirements. A subsequent calibration of tolerances ensures the
high precision requirements on the connecting rod, where the parallelism
tolerance is 35 µm with a hole tolerance of only 6 µm.
The valve plates are typically designed with multi holes / channels, this
can be included in the pressing operation, thereby achieving net-shape
design without subsequent processing.
FORESTRY AND GARDEN
- FJ Sintermetal manufactures components for professional
machines for maintenance of parks and forestry. Components for lawn mowers
and clutch parts for chainsaws can profitably be manufactured in powder
metal. These components are typically hardened to higher hardness due to
requirements of high mechanical and wear properties.
- The sintering process is particularly suitable for the
manufacturing of gear components. Gears in one or more levels can be
manufactured directly in the tool with high precision. A quality class 8 can
typically be achieved and a module down to about 0.4 can be manufactured in
powder metal depending on the number of teeth.
- Powder metal components are found in many appliances and
machines used in the household. Among others are components for sewing
machines often made of sintered metal due the precision in the process.
Design is a keyword and materials could typically be stainless steel, or
made with a coating, if a neat and uniform surface or a particular color is
- FJ Sintermetal manufactures various components for hydraulic pumps. These
pumps are characterized by operating at high speed and high pressure that is
at 270 bar, which requires a high precision and strength of the sintered
- The powder metal process is used for manufacturing
locking systems. Components for locking of doors are usually small with
complex designs and in order to ensure high level of performance, tight
tolerances are generally reqiuired. Components are often made of stainless
steel or coated in order to obtain good corrosion protection.
- Components for electrical motors are typically
manufactured in soft magnetic materials. Materials used can be pure ferrite
or silicon and phosphorus alloyed. Depending on the desired magnetic
properties soft magnetic composites (Soft Magnetic Composites = SMC)can be
used, resulting in a 3-D high-flux induction and high resistivity, low core
loss comparable to that of conventional laminated steel sheets.
- The powder metal technology is a suitable manufacturing
method for many components within fittings, filters and other parts designed
for industrial use. The cheapest and simplest form of sintered components
are achieved simply by pressing and sintering without subsequent machining.
- Many tool parts can conveniently be manufactured in
powder metal when requiring uniformity and narrow tolerances. Components for
Power Tools require high mechanical properties and high precision. Clamps
with special trays can also conveniently be manufactured in powder metal due
to the many design options. Positioning systems for machining require good
material properties with high precision.
- Sintered components are often used as a basis for pump
components. With a subsequent calibration, fine tolerances are achieved
which are required for achieving a good vibration-free pump operation.
Bushings are typically made in special designs of bronze and sealing systems
in stainless steel. The components can be treated with a galvanic coating to
increase corrosion resistance.
- For automation of opening and closing operation of
windows powder metal components are typically used as the mechanical
operating element. Reduction gear motors are examples of this. The advantage
is that you can manufacture precision components at low cost in large
series. The components are usually surface coated to increase corrosion
- There is a wide range of design choices for sintered
metal components, and their areas of use are continually being enlarged.
Whether the powder metal component is manufactured in steel, stainless
steel, bronze or maybe soft magnetic materials is often determined by the
design and end usage of the component. Our powder metal components are often
used in mechanical applications but powder metal components are actually
used in everything from transmissions and fastenings to electromagnetic
In cooperation with our customers we continually discover new opportunities
for using sintered metal parts and the benefits and advantages of the
process. Do not hesitate to contact us if you have questions concerning
choice of material for your component.
Steel alloys are the materials most commonly used in manufacturing sintered
The many options for alloying the pure iron powder mean that materials can
be adapted to offer the specific properties the customer needs.
The strength of solid steel can also be achieved with sintered metal.
FJ Sintermetal uses several types of powder to manufacture stainless steel
A selection of your options can be seen below.
316 An austenitic and non-magnetic stainless steel powder with good
corrosion resistance and mechanical properties. The most commonly used
410 A martensitic, ferro-magnetic stainless steel powder that can become
extremely hard and therefore has good wear resistance.
430 A ferrittic stainless steel powder with enhanced magnetic and corrosion
resistant properties in comparison with 410. Used for applications where
there is a need for corrosion resistance and magnetic properties.
Sintered bronze is mainly used for bronze bearings, but due to the good
frictional properties of the material, it has many other areas of use.
Items made of sintered bronze are often calibrated and can therefore be
manufactured to tolerances down to tolerance grade IT6.
Soft magnetic materials
Sintered metal can be used with great advantage for applications that
requires soft magnetic properties, such as magnetic cores or other products
that have electromagnetic components.
Sintered metal adds a number of advantages to these types of applications in
several areas, such as design, uniformity, quality, and price.
- The sinter metal process involves compressing metal powder
in a precision tool and then heating or sintering the component to create
metallurgical bonds. The sintered component is often the end component or
product and addtitional operations are not necessary.
This is one of the main benefits of the sinter metal process and a major
competetive advantage when comparing the process with other component
manufacturing processes like machining or plastics.
