Start a Rubber Stamp Manufacturing Business

 

(305). Start a Rubber Stamp Manufacturing Business

Rubber stamps have been utilized in all the business areas and became a significant need in all the businesses. It is used as signature on any kind of official documents. In simple words it is used as a common seal to sign any contract, bills, documents, etc.    Uses of Rubber Stamps: Initially such marking materials were used just for commercial purpose but today stamps are widely used in craft projects. Today stamping has become a hobby by which people can create different kinds of creative designs. Such stamps are made by different designs on rubber with quality ink pad, which is essential to design any paper, card or cloth.

 Types of Rubber Stamps 

Rubber Stamp Types

Presumably, rubber stamps began in the late 1800s.  A person named Andrew Schwab reportedly began Northwestern Stamp Company in 1881 . That makes rubber stamps a technology over 100 years old – an antique by definition. A company called X-stamper Online claims to have been making rubber stamps for over a hundred years. In large companies as well as small companies, each employee can have their own collection of rubber stamps to mark the documents they generate.  At times, these rubber stamp collections reached the point where the worker had a single desk drawer for their custom rubber or self-inking stamps. All had to be manually applied

Self-Inking Stamps

There are self-inking stamps, dater and numbering stamps, traditional stamps that use stamp pads and art stamps.  The most common ones now used for document marking are self-inking.  These stamps are designed with a built-in inkpad and are “re-inked” each time the stamp is depressed and returns to its resting position.  Historically, they were carved and/or molded and required an ink-pad.  They still do!  That pad contains the ink that the traditional rubber stamp uses to mark the document or object.  Custom rubber or self-inking stamps are still the most convenient type of stamp for marking odd-sized objects and boxes.  Some custom stamps were used to put logos, designs and other decorative art-work on paper when printing was much more expensive.

Industrial Stamps

These are an innovation in the area of pre-inked rubber stamps in that many have special ink formulations that speed drying time and that are waterproof.  Their design is intended to keep the ink from drying out and extending their life-time.  These industrial rubber stamps are designed to mark most anywhere and can be quite expensive by comparison.  For example.  A three-line stamp Xstamper stamp that using 38 pt. (72 pts/inch) letters is 1.78in. x 3.37in. is $99.95 at one stamp company.  Most of these are custom stamps. StampIt can make any image that these stamps can make and the cost virtually free.

Pre-inked Xstamper custom stamp

These are supposed to be good for over 50,000 impressions. X-Stamper range in cost from $33.50 for a  1”x2” to $79.95 for a 1-15/16”x 2-15/16” to the $99.95 for a 1.8” x 3.4” that is indicated above.  Frequently, the custom rubber stamps will become lost before they wear out. In large companies, the cost of these X-stamper stamps for each employee that uses them can become quite significant.  Some users become addicted to rubber stamps and tend to use them at every opportunity. Again, if these stamps are used for paper documents, StampIt can create them virtually free and with far more latitude.

Pre-made Stock Stamps

Much of paper document marking and stamping is done with “stock pre-inked rubber stamps.”  Stamps such as Approved, Copy, Client’s Copy, Draft, Confidential, Copy for your information, File, File Copy, First Class Mail, Important, Personal, Revised, Rush and the like are available for approximately $9.50 each.  These stamps are usually ½” in x 1=5/8” and come in colors. Here again, StampIt has these images built into the program and they can be used "as is" or customized to any size, color or font, virtually for free.  
    
Signature Stamps

Signature Stamps are similar to rubber or self-inking stamps but used to place a fascimile of a person's signature on a paper document. To order one of these stamps, the use simply scans a copy of his signature. StampIt, again, can apply this signature, automatically, to any document and selectivly use it where the user designates eliminating the manual process.

Manufacturing

Once the rubber stamping manufacturing business entity is established and operational, rubber stamp prototypes are created to present to factories for production. The prototypes will give a clear picture of the type of stamp to be produced and the opportunity to test different stamp artwork prior to investing in full production. By choosing different rubber stamp patterns such as delicate borders, words, quotes or character faces, you will be able to build different product lines for your potential customers.

Instructions

Draw your rubber stamp's artwork on drafting paper with your drafting pencil keeping your acrylic block's size scale in mind.

Create your design's stencil by tracing your artwork on card stock. Draw defined lines of the artwork with a dark fine tip marker.

Scan your defined outline into your personal computer's graphic design software program and save the work. Define the outlines with your program's linear and curve tools to ensure the lines are precise. Keep in mind that stamping is based on outlines, accent lines as well as specific breaks within the artwork pattern for the crafter to color in or embellish.

 Print out the artwork stencil on card stock.
Place your stencil on your cutting board and cut out the negative areas of the stencil with your craft knife. The negative space is the rubber stamp's defined lines. Leave the positive areas intact. This will be your rubber stamp prototype.
Position your stencil on a flat rubber sheet. Draw in the negative spaces with a permanent marker. Remove the stencil.
You will also have to mark the rubber stamp's parameter with a ruler for your acrylic block. For instance, if the acrylic block is 5 by 5 inches, make the rubber stamp backing 4-1/2 by 4-1/2 inches
Place your rubber sheet on your cutting board and cut out the positive space with a sharp blade craft knife. You will have to cut carefully. The stamp's outline as well as accent lines will appear. This will be your unmounted rubber stamp.
Draw the dimensions of your unmounted rubber stamp on the mounting foam's protective backing sheet. There is protective backing on both sides of the mounting foam sheet and both sides have very strong adhesive.
Cut out the mounting foam with your scissors. Remove the protective backing. Make sure the area is free of dirt or debris to ensure the adhesive remains clean..
 Stick your unmounted rubber stamp onto the mounting foam
Remove the remaining layer of protective backing from your mounting foam and stick it to your acrylic block to complete your rubber stamp prototype.

The Manufacturing
Process

1. After a rubber stamp design is selected for manufacture, a drawing of the design is photographed, and multiple copies of the image are transferred to an aluminum plate. The plate is then bathed in acid that eats away the exposed metal so the design is etched or raised above the plate.
2. The engraved plate (a positive image) is placed on a sheet of Bakelite, a registered brand of resins and plastics that can be used to produce finely detailed molds, in the rubber stamp press or vulcanizer. Under heat and pressure in the vulcanizer, the engraved plate leaves a negative mold in the resin sheet. A sheet of rubber is then laid over the Bakelite mold, and both are heated in a vulcanizer to produce the final positive image in rubber. Vulcanizing is a process in which crude or synthetic rubber is treated with heat and pressure to alter its properties of strength and chemical stability. Vulcanizers were developed as part of the rubber tire industry but are now used in many applications to treat rubber, fibers, polymers, and other materials. Operators of vulcanizers have their own techniques for producing the finest products, and the time and pressure used to vulcanize a sheet of rubber depends on the size of the mold and the operator's experience. Typically, a sheet of rubber stamps is subjected to 900 lb (408.6 kg) per square inch of pressure for about 3 minutes to complete vulcanization. The Bakelite molds are also vulcanized under about the same conditions. The mold or rubber sheet is then removed and set aside to cool.
   
3. Some manufacturers use sheets of photopolymer resin instead of rubber to make stamps. The resin is applied in liquid form to a negative transparency that is protected by a thin plastic film. A backing sheet is placed over the resin and the whole sandwich-like plate is placed in a photorelief printing plate machine. The machine exposes the negative and the resin to ultraviolet light, which transfers the image. The plate is then placed in a post-exposure unit that dries the resin. The sheet of resin is
   
   then handled just like a sheet of rubber in the following steps to complete a stamp.
4. Most of the other steps involved in producing rubber stamps require skilled hand labor. The sheets of formed rubber are pressed onto sheets of adhering material with adhesive on both sides. The mounted rubber sheets are cut into individual stamps by workers using scissors. They must cut the stamp so that the design is not damaged but also so that enough excess material is trimmed away to limit the likelihood that they will pick up ink and spread unwanted impressions. Some designs are cut on a clicker press, which is a die press that cuts predetermined shapes by applying pressure to dies with razor-sharp edges.
5. The backside of the adhering material supporting the trimmed rubber stamp is mounted on a specially sized block of maple. The wood blocks are made in standard sizes by an offsite manufacturer. Only hard rock maple is used so that the design will not bow or be distorted by natural
   
   aging of the wood or by changes in temperature and humidity. The blocks of wood are hand-rubbed with linseed oil, which helps protect the wood. The designs are mounted by hand, and exceptional care is required to mount the designs squarely. A clear piece of adhesive plastic is placed on the top of the maple block. The stamp design is imprinted on this label, which is called an index. The manufacturer Hero Arts developed a color index to show the design of the rubber stamp and suggest ways in which it can be colored to best convey the design. These labels are also made by outside suppliers.
6. Other steps in the manufacturing process are needed for some specialized commercial stamps. Date stamps and similar stamps with a variety of phrases are made of strips of rubber with the numbers or phrases impressed in them. The rubber-band-like strips are seamless and are placed on metal mounts that can be rotated with a dial or a key on the side of the collection of stamps. Thin sheet metal is used to manufacture the housing for the stamps and the dials or key. A wood handle is attached to the metal mount on the opposite side of the device from the printing image of the stamp. Plastic mounts are used for some commercial stamps with a single stamp for highly repetitive use or with the self-inking kind of commercial stamps that allow room for the stamp to reverse itself in the case and rest against an enclosed ink source.
7. Finished rubber stamps are sorted and stored by type. As orders are received from retailers, the stamps are selected individually for packing and shipping. In some cases, sets of stamps are made and prepacked for sale only as sets. 

8. Simple method of manufacturing of rubber stamp at low cost.

   Rubber stamp is an essential thing for these days, Mean to say that every important work is sealed by rubber stamp.  Rubber stamp is mostly used in every offices, schools, colleges, banks, Govt. offices, shops etc. Manufacturing process of rubber is very lengthy and long process. It takes more time. But now these days with a new developed techniques it is very easy to make rubber stamps in less time. The investment is also less for the new techniques. A small single room is sufficient for it.
   
   Advantages
   1) In new process laser printouts are used which can be made by various designs and sizes in DTP.
   2) No skill worker is required for this method.
   3) It takes very less time then te older method so the electric consumption is low for this method.
   
   Method
   As we discuss the new developed process is very simple and very easy. The of rubber stamp is taken by laser printer. Then a negative of this printout is made and this negative is kept on the bottom glass of machine  and fixed firmly without any creases. Then liquid polymer is poured in uniform layer which sets on the various part of negative. The excess polymer is removed by a special formulation/  brush. Finally this impressed polymer is processed and after drying. The seal is prepared by attaching a plastic holder. The whole process required minimum one hour which is very less time then the older process.
   
   Machineries required     
   1) Nylon stamp photo polymer exposer unit(12 V B tube, starter, clamps, 3 pairs of thickness gauzer bar, wash brush, port exposer tray etc.)
   2) Negative exposer unit, film washing and development tray, hot air blower etc.
   3) Other h/w tools.
