Sign Industries Ltd is a small business which specialises in etching onto Brass, Bronze and Stainless Steel.
OUR STORY
The company which was originally formed in 1989 was then re-formed in 2017 following the retirement of its founding owners. Jordan Law a former employee of the original company since 2004, decided that the years of experience and techniques would not be lost and that the doors to Sign Industries would remain open to existing and new customers.
Let us take you through some of the processes for different methods and materials we use.
PROCESSES
The Process of Etching:
First we cut your metal, we have a fairly large guillotine for cutting normal squares etc, if we need an odd shape we send it to a laser or water jet cutter to get that done so any shape is possible! We then cover the back side of the metal with vinyl and make a mask with the pictures or legend on it, this is placed on the front of the metal which has been polished and finished by the supplier where the letters and images are then picked out, any part of the sheet which has not been masked will etch. It is then placed on runners to go through the plant, we use ferric chloride to etch, which is a salt although the process is called acid etching there is no acid involved. The metal usually has two passes to get the depth needed but that can depend on the material, S/Steel is harder than bronze so it takes a little more time. By etching, it means we can cover a bigger area with more text, mechanical engraving on to S/steel is very time consuming and much more expensive. It then gets cleaned and with the mask still on, progresses to the paint shed. We use a 2 pack car paint to give longevity. We can do as many paint colours as you like but they all have to be done separately and we must have a thin divide of metal between the colours or they’ll mix together, it is only then that the vinyl is removed, the last job is polishing and packing, for delivery we use a carrier who gives us next day delivery to most parts of Great Britain.
Sublimation:
We print out the legend on to photographic paper with special sublimation ink, the paper is pressed on the metal which has a polyester coating, (or a sweat or T shirt which has polyester through it) where it‘s placed on a heat press, the combination of heat and pressing transfers the ink to the metal where it becomes permanent. It’s a good system for badges, inside & small signage but it can fade in the sun.
Aluminium Signage:
These are everything from road signs to large factory signs. Depending on the quality of the vinyl used they will last for 15 – 20 years. The aluminium is cut to size and the legend is placed on where it is rolled to secure. We don’t have the facility to make special designs but we know who to contact to get that done.
Before the change in countryside legislation we made almost all the Rights’ of Ways signage so most of the green signs are ours.
Foamex Signage:
Is much the same principle as the aluminium but a slightly cheaper and not quite such a hard wearing backing. As temporary signage it’s great as it’s not so heavy to handle.
Laser Engraving:
We can also work on Perspex, wood, slate and traffolite with our laser cutter. The traffolite or rowmark plastic is like a sandwich with different colours fused together, we can laser through the top layer to reveal the under layer showing the contrast. This is often used by Gardens to name the plants, it also makes good memorial plates which are fairly long lasting but not as expensive as the normal bronze plaque.
Perspex Signage:
Our newest signage is Perspex based which you’ve seen before, it suits the more modern buildings.
Backing Boards:
And lastly we make our own wooden backing boards with a clever system to secure and hang.
