Hot Stamping Machines
Offering Expert Automation Systems
Acromark is your most reliable source for hot stamping equipment and supplies to meet your every decorating need. We have been the leaders in the development of new hot stamping technology since the hot stamping of plastics had its origins in the 1960s. Today we can offer you a full line of machinery, fixtures, dies, foils and transfers to deliver your company a truly turnkey decorating system.
Acromark manufactures a full line of standard equipment with vertical, roll-on, and peripheral marking machines designed to meet your productivity requirements. We offer Small Tonnage vertical presses for personalization and fine detail, rubber die applications; Large Tonnage machines for Heat Transfer/Digital Heat Transfers and large area foil stamping jobs; Roll-on Presses for tip stamping and full surface wood grain foiling or metallizing; Peripheral Markers for round molded parts such as pens and pencils, number wheels, jars, jar lids, and bottle caps.
Acromark pioneered peripheral hot stamp decorating of cylindrical parts. Today our machines are used to decorate toys and tumblers, plastic cosmetic jars and lids, lawn sprinkler heads, and cosmetic lip treatment containers, using metallic and pigment foils as well as preprinted Heat Transfer/Digital Heat Transferss.
Acromark is a leader in the design and construction of automated decorating systems. We can design and integrate fully automated systems with bowl feeders, automatic part loading and unloading, date and bar coding, in-line quality control, and packaging. The addition of laser markers, pad printers, and stations for assembly can also be integrated into our systems.
hot stamping and silk screening
Hot stamping is a dry printing process in which a metallic or pigment color is transferred to a substrate by means of temperature and pressure. Preprinted images, called "Heat Transfer/Digital Heat Transferss", provide the means for applying multiple colors in a single stamping operation. Both the single colored "foils" and multi-colored transfers are supplied as a continuous film in roll form. These rolls have extended shelf life stability and the use of these dry foils allows for quick and easy color changes in a decorating operation.
Color is released from the carrier films through the application of controlled heat and pressure. For single color applications of discreet images, a metal or silicone rubber die is created from black and white artwork. These dies can be flat or contoured to match specific part requirements. Full surface coverage can be achieved through the use of machines equipped with heated silicone rollers. Peripheral marking is also achieved with either rollers or flat dies, through the use of specially designed machines.
The hot stamping process is clean, dry, and fast with permanent bonding achieved immediately upon application to the part. There are none of the problems involving inks or solvents as are associated with various wet ink printing processes. Hot stamping is used on such common applications as greeting cards and book covers, TV cabinets and kitchen appliances, cosmetic packaging, writing instruments, toys, and beverage crates.
From simple gold "leaf" personalization to the application of a four color process reproduction of a photograph, hot stamping is a cost efficient decorating technique that is easy to set up, clean to operate, and capable of producing products that will last for years. It will also create a profit center for your business that may ordinarily be overlooked in the manufacturing environment of today's economy.
Acromark can supply your company with a complete decorating system inclusive of all the tooling and consumable items needed to produce your finished, decorated parts. Fixtures and dies, foils and transfers, everything needed to supply a turnkey production system is offered through one single company. To get started, send us a sample or drawing of the part you plan to decorate, along with the artwork you plan to use in the application. We will send you a complete recommendation for equipment and supplies at no cost or obligation. Sample decorating is also available through our lab, with the only charges possibly entailing prototype tooling costs. Contact us today to join the growing family of satisfied customers who have discovered the benefits of working with Acromark Industries.
HEat Transfer and digital heat transfer
Heat Transfer/Digital Heat Transfers (dye sublimations) decorating is a dry process that uses preprinted decals to decorate a particular part.
Heat Transfer/Digital Heat Transfers decals provide a high quality screened image that is permanently bonded to a part by way of the hot stamping process. Before the decals can be applied to a part, the part to be decorated is analyzed, so that the proper ink/lacquer /carrier construction is selected. The Heat Transfer/Digital Heat Transfers decals are then printed on large gravure or screen printers on large sheets.
In addition, since multicolor images can be printed in one hit, Heat Transfer/Digital Heat Transfers decals can be a cost-effective method for medium to large runs. Heat Transfer/Digital Heat Transfers decals can be applied to many substrates such as plastics, wood, coated metals, glass, painted products, leather, fabrics, and rubber.
Silk Screening Machines
Specializing in Silk Screening Machinery
Screen Tech began 29 years ago in the decorating tooling market for 3D products, which led to our first screen printing machine being built in 1981. Since that first machine, our company expanded into hot stamping, Heat Transfer/Digital Heat Transfersring, labeling, laser marking, assembly and packaging lines of equipment, as well as total custom designed and built machines. In autumn of 2005, we purchased Acromark, to add to our high-quality fleet of machines. With several thousand machines in operation, and our expertise in high-speed registration and parts handling, Screen Tech is an industry leader for all your automation and decorating needs.
Silk screening describes the process where an image is transferred to the printed surface by ink, which is pressed through a stenciled screen and treated with a light-sensitive emulsion. Film positives are put in contact with the screens and exposed to light, hardening the emulsion not covered by film and leaving a soft area on the screen for the squeegee to press ink through. A different screen is created for every color you print then each color is run separately allowing drying time in-between.
A screen is made of a piece of porous, finely woven fabric (originally silk, but typically made of polyester or nylon since the 1940s) stretched over an aluminum frame. Areas of the screen are blocked off with a non-permeable material-a stencil-which is a positive of the image to be printed; that is, the open spaces are where the ink will appear.
The screen is placed on top of a piece of dry paper or fabric. Ink is placed on top of the screen, and a squeegee (rubber blade) is used to push the ink evenly into the screen openings and onto the substrate. The ink passes through the open spaces in the screen onto the paper or fabric below; the screen is lifted away and then the squeegee is pushed back across the screen, with the screen lifted, "flooding" the ink into the screen. The screen can be re-used after cleaning. If more than one color is being printed on the same surface, the ink is allowed to dry and then the process is repeated with another screen and different color of ink.
Many of our machines can be used to decorate a variety of parts with the simple incorporation of additional custom tooling. A brief phone consultation can help you learn if your current equipment can lend itself to decorating or automating new and different parts.
Assembly & Automation Equipment
In addition to or in conjunction with our extensive line of decorating equipment, our capabilities include the incorporation of automation and assembly features such as bowl feeders, stackers and de-stackers, robotics, pick-and-place and many more. From semi-automatic to fully-automatic solutions, these integrations can improve your process times and increase your product quality while decreasing your company's long-term operational costs.
