Vulcanized Rubber Stamps:
One of the most familiar rubber stamps that everyone aware about it is traditional red rubber. This was actually manufactured using vulcanizing press. Vulcanizing is one of the most effective methods to manufacture rubber stamps in mass. Usually batch of stamps produced using a mould. The same mould allowed to use many times for the making of stamps. But in case of manufacturing custom-made stamps, you can use only once moulds to get the impression will may increase the cost of manufacturing much.
Making The Mould:
In order to create a mould, you may need a master plate from metal or polymer. Using the master plate, you will get an impression in the mould. Now you have to press the master plate into a matrix board thereby creating a mould. Manufacturers have to apply the necessary heat and pressure to both master plate and matrix board, after it is kept inside Vulcanizing Press. The matrix will get the shape which will become harden on cooling.
Making Rubber Stamps:
It is very easy to create stamps, once the mould done. Now you have place the raw rubber stamp gum inside the stamp press after gum placed on top of mould. Hydraulic pressure applied upon the rubber and the mould, which will take the rubber to get the shape of mould by melting into the areas of the mould containing text or images or any other things within 10 minutes.
Advantages – For producing mass stamps, this is really a cost-effective method.
Disadvantages – Requires high cost for producing master plates and moulds for custom-made stamps.
Laser Engraved Rubber Stamps:
For manufacturing laser engraved rubber stamps, you can’t use traditional raw rubber, as the laser requires even thickness and free surface to get impression of image or text from a stamp die. So the rubber has to undergo certain curing process before allowing it to the laser beam temperature.
The depth of impression depends on how much laser speed applied and how much the density of rubber. In the laser engraving process, the machine will release excess dust cleaned using exhaust filtration system. Mirrors, lenses and any exposed bearing surfaces cleaned thoroughly to keep up the overall laser engraving system.
Advantages – Custom-made stamps manufactured easily with the production process.
Disadvantages – Maintenance costs is very high.
Various Types Of Stamps:
There are varieties of stamps manufactured using the above methods include self-inking rubber stamps, date stamps, multi-color self-inking stamps, pre-inked stamps, embossing stamps, common seal, JP & certification stamps, stock stamp
Summary:
Most of the stamp manufacturers will have the mix of above equipment for making stamp. Most of the unmounted rubber stamp dies easily crafted to produce simple hand stamps, dater stamps or self-inking stamps. Check about the quality of stamps, before buying them from manufacturer.
