The products and services assortment is a ceaselessly grooving group of services for our clients, oriented, first of all, to understand and to render their needs, and to try to adjust the ordered service or product so as they are required or as they are allowed to be done by the technology available to them. There is an intention, to get information available in a maximal possible extent, during parameters determination, and to get acquainted with the processes of the client, so as we could calculate with as many inputs as possible at size, composition, durability and many other terms determination. Then the faults due to insufficient knowing are eliminated in a maximum extent. The client itself is the first and most important source of information in this stage of design.
production-preparation technical-engineering - since the year 2000 we have two engineering and design stations at our disposal equipped with SOLID EDGE software. We are equipped also by one programming station for CNC 3D milling centre, equipped with POWERMILL software. Here are concentrated all the requirements coming from clients and from production. All data are processed in 3D first, a functional arrangement is then created on their basis, in three-dimensional models, and the individual detailed drawings for production needs are elaborated as well. All computer stations are connected to one network so as an immediate connection can be created, with the given participant, for any exchange of data or programs for CNC control, and feedback needs from production and design can be created as well.

CUTTING TOOLS – Are the tools where the hardened shearing tool edge penetration (intersection), through the cut material, to the hardened shearing support, with the required dimensions and shape, takes place. The material thickness for which we have manufactured tools already are ranging from 0,15 mm stainless steal spring wires, up to 22 mm thick 70 mm wide material of 11373 grade. The cutting tools are divided into more categories: ordinary, single-purpose, multi-purpose, with interchangeable shearing parts, and then more complicated ones with combination of more successive cuts – steps, these are manufactured in execution either for manual handling or in connection with stock feeder for automated cycle.

BENDING AND DRAWING TOOLS – With these type of tools the material, normally leveled, is being pressed between two hardened forming jaws, so as it should stay in the required final shape at the process finalization. These tools can also be divided into two main categories, namely to multi-purpose tools, where the forming part is a simple form of “V” shape most often, in general, and there we can achieve various products similar in shape and size by simple stops, and pads application used for press adjustment and setting. The other group, the bending tools, already with their naming define their application purpose, and they are designed for forming of special shapes given by the part design profile, single –purpose in preference.

PROCESSUAL-OPERATION (PROGRESSIVE) COMBINED TOOLS - More or less, in fact, they are true equipment in which the elements of the two former tools are applied in re-defined order, so as the required shape – the proper product is reached by the last operation completion. These tools are designed in case when the client took a decision for to manufacture a big series of products, and he needs to increase either the production efficiency or to minimize the number of operations, and to minimize he handling needs with the products in interim operations as well, these tools simplify all the production process, and thus all the process is more progressive –more effective then.

Moulds for plastics – Cavities with a system of inlets are made there, in shaped panels, into which the plastic material is injected in fluid state, under certain pressure application. Consequently the plastic material stays in the cavity for a cooling period. Following the mould opening, the ready plastic product, together with the inlet system, is thrown out from the mould by ejectors. Following the mould closing, the cycle is repeated. Plastics utilization, nowadays, is present in all industry branches, so the variety of mould types responds both the purpose of each product, and the plastic material performance of which the product should be made of. The moulds are manufactured also with respect to client’s demands, either concerning the cavities multiplicity in the mould, hot inlet systems requirement, or other technical parameters. Both, the combination of different forms in the mould, and the amount of the required products determine the mould complexity and the material used for shaped parts as well. Most common are the moulds for serial production of products intended for mass consumption. Prototype moulds are produced as well. In this case a cheap and simple manufacturing way is chosen, as it is not known if the product will meet the required criteria and if it will not be necessary to execute some adaptations in shape. After successful approval the moulds for serial production are manufactured, where all the problems were debugged on the prototype mould and the mould for serial production can be introduced into the production.

MOULDS FOR NON-FERROUS METALS (CHILL MOULDS) - like in moulds for plastics, there are made cavities with inlet system and some spew groves as well, given by the dimensions and function of the product, and also they contain a system of ejectors, but the materialization should by carried out with looser allowances, as it comes to bigger thermal expansion due to materials of higher melting temperature utilization, and so to possible position change of all moving parts mutually. The moulds are produced either in version for gravity- casting or for pressure-casting. With casting under pressure the allowances should be tighten, as the material, driven by pressure, requires mould joints closed more tightly. In general, these moulds are manufactured for products where either the material can not be replaced by any plastics, material rigidity is required or environmental resistibility is necessary, or it is necessary to prevent any scrap waste origination with big production series manufactured of non-ferrous materials by traditional cutting operations. The surplus material – the boss- is removed by band saw obviously and then it is re-cast.

DIES – Their use is like chill moulds, where it is necessary to avoid any material losses due to cutting machining or such machining inevitable need minimization only to the functional parts. They consist of two shaped matrixes between which a piece of a hot material, of necessary volume for matrix cavities filling-in plus some allowance material for addition, is being placed which is cut-off on the GRADING (trimming) TOOL in the following step. It use to be of simple design, where through a matrix, with cutting edge copying the forge circumference, this forge is pressed through downward by a pusher. After cutting-off any eventual imperfectness they are processed by barreling or are grinded by grinding tools according to the needs.

MOUNTING BRACKETS – They serve for two or more components into one unit mounting simplification, either manually or by the help of pneumatic ore hydraulic pressure if higher forces are need. This equipment are special purpose ones and it is necessary, for their function, to keep the in-advance-defined parameters and dimensions of the individual components, to lock their mutual position, and mainly for easy taking-in and taking-out of both, the components, and the final built-up assemblies.

CONTROL MASTER JIGS – They are intended for direct products checking or for their locking into the measuring equipment. The products are assembled into them to the pre-defined or agreed fixation points, like during assembling into a real unit. Quick clamping devices are used with pre-set clamping force for position locking. Then the dimension checking takes place at pre-defined points, either by the help of calibrated timing gauge or by measuring equipment directly, during which the actual position of the control master jig is measured first , and then the actual position of the product is checked.

SPARE PARTS - The parts for the already mentioned tools and equipment, and parts for machines of different use up to the dimensions of maximal ranges of our technologies available are concerned.
