Make Rubber Stamps: Comparing Methods of Manufacture

The traditional rubber stamp red Everyone knows how it's done curing press. The rubber stamp vulcanizing press was patented first in 1890 by Charles Schultze in New Orleans, USA. Vulcanization is now one of the most profitable to do for rubber stamps stamps mass produced. Each batch of stamps produced by molds. This is a production method better seal to the contract by the same model used repeatedly. Make a custom stamp increase vulcanizing press requiring 'once "production model operating costs significantly.

Make a model - the model before it can do, you must be a master disc of metal or polymer master disk is necessary to develop (with photo) to make an impression in the mold. After the file each time the soil is required, increasing the cost to manufacture vulcanized stamps. Government support to create a set of tiles teacher to take the rubber mold. The temperature and pressure applied to the master disk array and curing press the government. Matrix includes a photo of the main relief plaque hardens, at its discretion.

Making rubber stamps - stamps is to create a simple process when making the model. Raw rubber stamp gum is placed in the mold and then put pressure on the piston. The hydraulic pressure, the combination of rubber and mold inside the stamp press causing the rubber mold areas, including images and text, drying and hardening takes about 10 minutes. Vulcanized rubber sheet was from the mold and cut into individual pieces to fix stamp assembly.

The vulcanizing system cost approximately $ 12 000 AUD

Advantages - Low cost of production of mass produced stamps, good ink transfer.

Disadvantages - Cost of producing master plates and molds produced a postage stamp.

Laser engraving rubber stamp

Death of the traditional material used for the vulcanization of rubber stamp quite unacceptable for the production of laser stamp dies, laser process requires a very uniform thickness and free from defects in the surface to produce an acceptable print because of the seal of the image . The harder rubber before it is exposed to the laser temperature rise.

The depth depends on the etch rate and laser power density of the rubber. For example, records 100 W recorder 50 or the rubber deeper and faster than 25W machine, which can go to get similar results. Usually must provide a high quality A4 sheets of laser engraving rubber stamps death, and adequate compressive strength and properties of the ink also.

Help etching process requires removal of dust created by continuous laser cutting measures, in fact, the leaking exhaust. As engine little or no CO2 laser engraving originally built for engraving and cutting rubber, installing and maintaining an effective dust extraction will pay dividends in the long run. Surfaces must mirrors, lenses and influence good cleaning as part of regular maintenance. Any negligence in this area without prejudice to all the problems of laser operation, such as dust and residue effects on efficiency and quality of the finished stamp die. Lasers are controlled directly from a computer, software drivers work with lasers and many graphics programs like Corel Draw.

25-watt laser is considered suitable for the seal of $ 40,000

Advantages - Production is computer controlled, custom stamps can be easily

The large investment costs, operation and maintenance is much higher than vulcanizing or polymer manufacturing processes - Disadvantages.

Liquid polymer rubber stamp

Rubber stamp polymer change from liquid to solid to make stamps interesting enough. Polymer seals with two layers of glass with precision UV light that goes through the polymer artwork reinforce negative marks. Negative output is simplified by the introduction of technology based on water negative, photographic material for film production in the past.

The first step toward polymer stamp to print photos, clip art or text on vellum paper, almost transparent film.
Images of high quality brand products you need to use a laser printer, bubble jet printer ink is transparent when the ultraviolet light emitted if it is not. Easy washing water based negative after a few minutes due to UV exposure stamp machine.

Polymer with the bag is difficult to replace the old method of using foam strips to create a dam and pouring of rubber stamp polymers, the bag also examine the problems of aging to remove air bubbles from the polymer.

The negative image of the cover artwork and the polymer sandwiched between two layers of glass from 2 to 3 mm, the machine is exposed for several minutes. When you have completed the disclosure process is simple to cut open the bag, and take the excess unexposed polymer before returning the stamp die back in the machine 10 minutes to dry. When cured can be cut seals. Polymer bags are available in various sizes up to A4.

The building is about 30 minutes polymer seal.

Cost of polymer stamp making machines range from AUD $ 3.500 per unit of Australia seals are specifically designed for high-end computer-controlled units in the tables USD $ 15,000.

Advantages - lower investment, polymers make almost clear stamps are perfect for scrapbooking and card making. Relief stamp can control exposure.

Disadvantages - Early polymers did not accept inks and polymers available today, new technology caused initial resistance to polymer stamps.

Summary

The leading manufacturers of stamps combination of the above devices. It can be unmounted rubber stamp dies produced by this production one of the cut and date stamp to simple hand stamps or ink. Art Stamps normally attached to wooden blocks, or install adhesive revenue stamps acrylic polymer blanket arrest or charge. Manufacturers produce different pockets. Astro Industries in Australia manufacturer of hand Vuestamp clear tone, "and also share an excellent range of automatic assembly. Other signs of assembly machines are Trodat, Colop and shiny.
