In our continuing efforts to improve
quality and service, this section has been prepared by our Quality Assurance
Department as a guideline for incoming items to be coated. Some of the
items in the following list are understandably unavoidable in certain cases,
but attention to all of these details can only affect the quality of your
valuable parts in a positive way.
Labelling – Important!
All parts to be coated should
arrive at Colourific well labelled. For example, your company name
needs to be clearly indicated on each separate
package,
the colour the product is to be
coated, and your purchase order number would also be helpful. Ensure
that Purchase Orders arrive with your order. Purchase Orders
must include a detailed description of parts to be coated i.e. quantity,
size, colour, part numbers if applicable, and any special packaging
instructions. This is a MUST. This will insure that your
material is easily identified, and will help us to complete your metal
coating more efficiently.
Packaging
Please ensure that the
packaging, containers, or skids you supply with your product provides proper
protection against damage. (For example, if your material is placed on a
skid it should not be larger than the skid, or “hang over” the space of the
skid.) Note that material will be repackaged in the packaging containers
you provide. Therefore, packages must provide suitable protection against
damage to the material as well as the coated finish.
Markers
All materials to be coated
should be free of inks, such as those from markers or other writing
materials. These inks can show through on the finished coating, (especially
when the parts are coated in lighter colours) and therefore should be
avoided whenever possible.
Weld Spatter
All welds should be clean and
the surrounding area is to be free of weld spatter whenever possible. The
heat involved can not only change substrate properties, but also incorporate
contaminants into the part surface (our pre-treatment process is only
designed for removal of surface contaminants and is not a suitable
substitute for mechanical cleaning). This will invariably compromise the
integrity of the final powder coating as manifested by bare spots and
pinholes in extreme cases.
Packaging Debris
All parts to be coated
should be free of packaging materials and shipping debris. While our
loaders inspect parts as they are hung on the line, certain problems have
arisen. The major culprit has been clear tape of various sizes and sorts as
they are nearly impossible to detect, especially in large orders. The end
result of this melted tape on the substrate is always complete coating
failure (e.g. zero powder adhesion). In conjunction with you, the customer,
Colourific hopes to minimize this problem. We only request that this issue
be addressed and awareness increased.
Oxidation and Hot-Rolled Steel
Any type of oxidation (e.g.
rust, white rust, etc.) can only affect the final product quality in a
negative manner. Our pre-treatment process cannot remove oxides
or scale, and if a
substrate is severely corroded (or has been lying around in a shop for an
extended period) the end product will have predictably less corrosion
resistance and a lower quality finish. The only solution is mechanical
re-finishing of the substrate, which cannot be done at Colourific.
Galvanized and Zinc Substrates
Poor quality of galvanized and zinc coatings
adversely affects the final product and in no way is Colourific liable for
lesser coating quality on these substrates. Ultimately, the customer
is responsible for the condition of the substrate before it arrives at our
site.
Drainage
All parts fabricated from tubing
should have drain holes, as powder will not adhere to a tube with water
trapped inside. Also, all parts must be hung on the line and as such the
configuration must be considered each time a new part is introduced to our
process. The sales manager will inform the customer of any special
requirements when the purchase order is placed.
This is only a guideline for you, the customer. Colourific is always
willing to assist in any way with the problems you may have and
understandably, these problems may be unavoidable in certain circumstances.
The purpose of this letter is to inform, not to delegate responsibility.
Through increased awareness of these potential pitfalls, quality and
efficiency of service to you can only be improved.
We greatly
appreciate and value your continued business.
