Standard Blasting Processes

The Vapormatt Contract Process Centre is equipped with a range of manual and automatic surface finishing machinery.
We can process your components utilising the following quality controlled processes: Dry blasting, Wet blasting,
Bead blasting, Grit blasting, Vapour blasting, Vaqua blasting and Aqua blasting.
Specialised Processes

We have developed expertise (through both operational experience and focused process research and development) in a range of specialised processes that are tailored to particular surface requirements.
|
| Composite preparation for painting / bonding |
 |
• Vapormatting gives a much more consistent
bonding than using conventional dry blast,
peel ply or hand flatting techniques.
• Resinous material can be removed without
damaging the fibres of the material.
• The lightly matted surface is very
“wettable” and retains the evenly spread adhesive. |
|
• The ever present water buffer prevents
impregnation of the resin surface.
• A water break test to ensure consistency of surface preparation is automatically carried out on every part processed. |

| Die & mould cleaning |
 |
. Our mould cleaning process using plastic
media
or other materials suspended in a hot
aqueous
cleaning jet, gently but thoroughly,
cleans moulds
and dies without surface or
edge damage.
. The Vapormatt mould cleaning process minimises
die and mould wear compared to
other cleaning methods so prolonging the
life of your tools. |
|
. Many types of contamination can be
cleaned
making our service suitable for
customers in the
glass, metal forming and
plastic industries.
. Our fast turnaround service allows tools to
be
dispatched within 2 hours of receipt. |

| Cutting tool enhancement for post grinding, pre and post coating |
 |
Tooling benefits
• Superior cutting tool performance.

• Stronger, longer lasting edges.

• Smoother, lower friction surfaces.

• Dramatically enhanced coating performance due to combination of pre and post coating
treatments |
|
Edge and face benefits
• Consistent, controllable edge radii.

• Semi polished faces.

• Extremely clean and reactive surfaces.

• Ideal pre / post coating treatment. |
|
|
|
| Wire, cable and strip processing for cleaning and surface engineering |
 |
• Our linear strip cleaning process produces
a variety of cleaning effects to remove a
range of surface contamination from
continuous material.
• Surface finishes and effects can be consistently applied on new wire, cable
and strip products without the negative
effects of chemical or standard dry blasting
processes. |
|
• Ideal for the reclamation of corroded or
contaminated material.
• Can be used to promote high levels of
bonding for coatings and / or additional functional layers of material.. |
|
|
|
| Shot peening for fatigue life improvement |
 |
The benefits of shot peening
• Increased life of critical components
vulnerable to fatigue failure.

• Wet and dry peening processes offered
according to requirements of your
pre-existing process specification.

• Process parameter record sheets
maintained for all shot peening operations. |
|
• Wet peening combines the benefits of
applying surface compressive stress, with the
advantage of a super fine non directional
surface finish. Such a combination can
inhibit crack propagation over and above
the simple effects of basic shot peening,
which can leave a contaminated and
deeply pitted surface.

• Wet peening is inherently a clean process
and secondary surface contamination as seen
with dry peening is dramatically reduced or
eliminated entirely

|
| Blacking for aesthetic enhancement of steel components |
 |
Our blacking process provides a durable black
finish that enhances the appearance and value of a
wide range of manufactured articles.
. The Vaporblack surface adds to the
perceived value
of engineered / machined
products.
. Vaporblacking provides an absorbent layer
ideal for
subsequent oil or wax
impregnation thus offering
enhanced
corrosion resistance. |
|
. The process is a chemical conversion
treatment,
not an additive process so
delicate tolerances are
not compromised.
. Operation at room temperature (18°C to
24°C)
so thermal distortion and stressing
are eliminated |
|
|
|
| Phosmatting for rubber to metal bonding and sub coating corrosion protection |
 |
A combined wet blasting and phosphating process in which a highly active mechanically cleaned surface is instantaneously exposed to an active phosphating solution, without the pre exposure to the oxidising effects of air. The benefits of Phosmatting
• An extremely dense, fine structured crystal
lattice is formed in the process. |
|
. The Phosmatt crystal lattice is tougher and
can
withstand greater substrate deformation
without
failure compared to conventionally
produced
phosphate coatings. This makes
the process very
suitable for rubber to metal
bonding applications
where metal is
subsequently compressed to
counteract
rubber shrinkage effects.
. Re-phosphating of selected areas, without
tripping
of the whole component, can be
achieved. This can
be of advantage in
rustproofing applications e.g.
small arms
repair and refurbishment etc. |
