of sharpening and life of the equipment
Bending machine (Active
edge 60 BIESSE)
The Active Edge 60
is the new compressed, semi-automatic edge banding machine for
straight and shaped panels. It is very easy to install, maintain and
operate. It is suited of applying edges in rolls (melamine, ABS, PVC, veener)
and in strips (formica, solid wood).Active edge machine is operated through pneumatic
system (required Air pressure for operate the machine)
Punching machine (AMC
Tantus 256)
Punching is a manufacturing process
used for metal forming .it is suitable for mass production. Initial tooling costs, of both the job-specific press tool,
and machine are high.
In the AMC Tantus 256 have 20 work
stations shown in figure that can
be rotated to give any tool to the punching location. A very easy shape (e.g., a square,
circle, or hexagon) is cut directly from the sheet. A complicated shape can be
cut out by making many square or rounded cuts around the perimeter. As a press
tool needs die set and a matching punch, there are two corresponding turrets,
above and below the bed, for punch and die. AMC Tantus 256 punch are CNC controlled, with automatic
locating of the metal sheet beneath the programmed selection of particular
tools V. A CAM process first converts the CAD design for the
finished item into the number of individual punch operations required, lean on
the tools available in the turret.

Problem associated with
punching machine (AMC Tantus 256) :
Many problem comes out in industry but
main problem is bur formation on sheet metal when using punching machine .
(1) Bur formation
Punching machine works on according to
program .machine has contained 20 tool
station within itself .the main problem of punching machine is formation of
exit bur ,for eliminating of this problem industrial manager decided to change the tool when exit
bur is more and the finally result comes out production cost per unit is much
more high . Secondary process (Hand Grinding) also required for removing the
exit bur on the sheet metal.
Exit bur on sheet metal
Solution
of bur formation:-
(1)Tool
must be sharp and proper clearance between tool head and work piece
(2)Make clear that this wear between a punching and the next is
invaluable but force go accumulating cushioning’s wear is growing rapidly. When
you spawn a radius of 0.25 mm in the cutting edge we had 100,000 hits. If taste
0.25 mm we will be in optimum conditions of punching and we give 100,000 hits.
Following this procedure when we have rectified up to 1 mm we will have made
400,000 hits.
(2)Problems
of sharpening and life of the equipment
One
such factor is the thickness and the type of sheet under punzonando. It is
clear that the force needed for shearing aluminum of 1 mm is not the same as
for shearing 4 mm stainless. Much more force is needed most as wear the
tooling.
Another
factor is the correct use of tolerances which we talked about earlier. If the
tolerances are not correct and fractures are not the tools should make more
efforts to make a hole
Benefits of
using a proper cutting tolerance in punching machine:
- Pieces flatter punzonadas, with
less distortion.
- Less Burr and curvature in the
holes
- Higher accuracy between holes
- Holes more uniform and clean
cuts
- Longer life of the equipment
(punch and matrix)
- Better extraction of the awl
- Lower membership material

Edge Bending (Jade 325)
Edge
Banding, is a process and a correlate narrow strip of material used
to create durable and a good looking pleasing trim edges during finish
carpentry.
Edge
banding is generally used to cover the exposed sides of materials such as plywood, particle board or MDF, giving the appearance of a solid or more valuable material
and increasing durability. Common replacement for edge banding include face frames or molding. Edge
banding can be made of different materials including PVC, acrylic, melamine,
wood or wood veneer.
Traditional
edge banding was a manual process need ordinary materials and carpentry tools.
In modern functions, exactly for high-volume, repetitive manufacturing steps like
cabinet doors, edge banding is putted to the substrate by an automated process
using a hot melt adhesive. Hot melt adhesives can be water or solvent based and
may include of many raw materials including EVA, PUR, APOA, and PO. A substrate
primer may also be used as a bonding agent between the sustrade and adhesive.
Thicker edge bandings typically require a slight concavity to provide a rigid
glue line. The thickness can vary from .018" to 5mm or even more. The
machine that puts the edge banding is called edge bander. An edge bander bonds
the edge banding to the substrate, trims the following and trailing edges,
trims bottom and top flush with the substrate, scraps any surplus, and buffs
the finished edge.
Jade 325, is a only one slide automatic edge banding machine
designed and built to meet the demand for flexibility and easy set-up for every
type of user, it also features uniquely solid structure. Available working
units are the gluing unit, end trimming unit, top & bottom raw unit, edge
scraping unit, glue scraping unit and buffing unit. The Biesse Group was established
in 1969 and today the Biesse Group create highly sophisticated, compact and
technological machines and systems to satisfy every industrial need for
generating and assembling furniture, doors and windows, furniture accessories,
and everyday objects in wood, glass and stone.

Powder
coating (Painting):
(1)
Powder Coating is an
advanced way to applying a decorative and protective finish to virtually any
type of metal that can be used both by consumers and industrial. The powder
used in the process is a mixture of finely ground particles of pigment and
resin, which is electrostatically sprayed onto the surface to be coated. The
charged powder particles adhere to the electrically grounded surfaces until the
powder is heated and fused into a smooth coating in the heal oven. The result
is a unvarying, durable, high quality and good looking finish. Powder coating
is the fastest growing finishing technology in North America, representing all over 10% of all industrial finishing
applications.
(2)Powder coating is a type of coating
that is putted as a free-flowing, dry powder. The main difference
between a conventional liquid paint and a powder coating is that the powder
coating does not needed a solvent to keep the binder and
filler parts in a liquid suspension form. The coating is generally applied a electrostatically and is then cured
under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is often used to generate
a hard finish that is tougher than conventional paint. Powder coating is mainly
used for coating of metals, such as household
appliances,
aluminum extrusions, drum hardware, and automobile and bicycle parts. Newer
technologies allow other materials, such as MDF (medium-density fiberboard), to be powder coated
using different methods
Properties of powder coating
Because powder coating does not have a liquid contained, it
can produce thicker coatings than conventional liquid coatings without sagging
and running, and powder coating produces minimal aspect differences between
vertically coated surfaces and horizontally coated surfaces. Because no
contained fluid evaporates away, the coating process discharge some volatile organic compounds (VOC). Definitely, several powder colors can be involved
before curing them all together, allowing color blending and bleed important
effects in a one layer.
While
it is relatively easy to apply thick coatings which keep to smooth, texture-free
coating, it is not as simple to apply smooth thin films. As the film thickness
is reduced, the film becomes more and more orange peeled in
texture due to the particle size and glass transition temperature (Tg)
of the powder.
Most
powder coatings have a particle size in the range of 30 to 50 μ (Microns), a softening temperature Tg around
80 °C, a melting temperature around 150 °C, and are cured at around
200 °C. for minimum 10 minutes to 15 minutes (Also its depend on thickness
of specimen or part) For
such powder coatings, film build-ups of greater than 50 μ (Microns) may be
required to obtain an acceptably smooth film. The surface texture which is
considered desirable or acceptable depends on the end product. Many
manufacturers actually prefer to have a certain degree of orange peel since it
helps to hide metal defects that have occurred during manufacture, and the
resulting coating is less prone to showing fingerprints.
There
are very distingue operations where powder coatings of less than 30 micrometers
or with a Tg below 40 °C are used in order to supply smooth thin films.
One difference of the dry powder coating process, the Powder Slurry process,
intermix the advantages of powder coatings and liquid coatings by dispersing
very fine powders of 1–5 micrometer particle size into water, which then gives
very smooth, small film thickness coatings to be created.
For
garage-scale jobs, low "rattle
can" spray paint are
costly and complex than powder coating. At the professional scale, the total
expense and time required for a powder coat gun, booth and oven are similar to
a spray
gun equipment.
Powder coatings have a some advantage in that the overspray can
be recycled. However, if multiple colors are being sprayed in a single spray
booth, this may limit the capability to recycle the
overspray.
