Presses equipped with head hollow punches that allows to scouring the shape of the tip and the holes along the center line or the shape of the back. In addition punching the seat pin buckle, hot stamping of logos and alphanumeric codes. Machines with: variable power cut , structure of the cutting plane and punches head; these can work in manual, semi-automatic or automatic.
Operations such as trimming, milling, grinding, polishing, brushing and polishing or filings are present in particular for finishing cut edges almost always present on the belts, often on bags and small leather goods in general.
When the material of the edges occurs porous and the small roughness are not removed, then it is necessary to intervene with an action of polishing to make the surface smooth. This can take place before or after brushing, depending on the quality of the material. The sanding tool to be used is an abrasive wheel that can provide the similar result obtained with very thin sandpaper grit.
The interventions of staining for the models in the collection, incorporating parts sharp cut, serve to beautify and give that touch the artifact that makes it more aesthetically appreciable. These operations can be obtained with machines that require different interventions by the staff regarding time and skill, and such equipment is normally divided into two groups: those manual and semi-automatic ones.
Immediately downstream of the dye-edge machines, in the production laboratories of leather goods some ovens or dryers are installed to allow the semi-finished parts to proceed through the next step, in fast sequence. A special configuration of these units is used to dry the color applied on the edges of parts of bags and folders or already assembled final products, such as bags, folders, briefcases and small leather goods in general. Another unit type is represented by a configuration for horizontal and vertical belts and the like.
Hot polishing edges achieved through glazing-blocks for glazing responding to the profile to polish. The versions with rotating tools or with vibration motion are used in the production of belts, shoulder straps and strips in general.
Plants to produce small metal alloy of zinc or tin by centrifugal casting. It involves the use of silicone rubber for the preparation of molds, as negative counterform obtained from the original positive, to be filled subsequently by casting, using some materials such as white metal alloys, low melting point, or the resins (epoxy, polyurethane or polyester), gypsum, etc.. The plants performs the realization of buckles, jewels, buttons and fashion accessories.
Performs hot stamping and numbering or with the use of golden ribbons or colored, to imprint letters, words and numbers for the identification and traceability of the product and mark prestigious logos to validate content and price. The operation requires accurate and timely preparation of the machine to get a flawless, clear and well marked.
