Arvitec has developed and extensive suite of extrusion equipment in partnership with its clients and drawing on more than 25 years of industry expertise.
In addition, together with our partners we include special and tailor-made equipment for all kinds of applications, from laser or ink printers and industrial welders for aluminium or stainless steel, control of artificial vision both on the surface and on the dimensional section, die-cast by design and customised, straight bending and over-injection.
Motorised metallic tape finishers, both for aluminium and for steel, designed to work in the in-line extrusion process. A finisher consists of:
The A-RF is easily synchronised with the extrusion line.
The universal head is an exclusive design to Arvitec. It has been designed combine four plastic materials in a reduced space with extruders of the same height and at the same time, whilst providing sufficient workspace for an operator.
Sufficiently large stainless block to provide stability to the work temperature by heat resistors (upper-lower).
Adaptable to the design of the client’s current die head to facilitate its integration.
Allows entry through the rear part of metallic tape, flock, chrome-plated foils, etc.
Compositions of up to 10 materials have been created with this original system for plastic extrusion and co-extrusion.
Calibration table and optimised refrigeration adjusted for technical profiles. The structure will be a structural tube of welded and painted steel. Control of position in l front zone in the three axes X,Y,Z using motors with encoder allowing up to 35 project positions to be stored. Refrigeration tank consisting of two 2 metre units to work with the submerged profile.
1-5 metre refrigeration tank by pressurised shower with polycarbonate to avoid the spatter of water. Independent drying zone with polycarbonate to deaden the sound. High-pressure electrical turbine to use an extra dryer with hot air. 500 litre deposit with cleaning system using detachable paper filter especially developed for flock tape profiles. Water deposit to reduce water pressure from the vacuum pumps, a system developed to avoid the loss of vacuum in leakage from these pumps. 25 litre pressureless water deposit and three outlets with spherical valves. Equipped with one or two vacuum pumps of 4 kW TRHC 40-110/C/RX Pompetravaini depending on the client’s requirements, placed inside the base [but] directly on the ground to avoid vibrations during the extrusion process. Light equipment along the base. The plate is prepared to work with an open circuit from the general installation of the plant or with a direct refrigerator and independent closed circuit, 10.4” touch-sensitive screen.
Drag for extrusion profiles with double band consists of:
The equipment allows rotation by the central part of the upper band so that possible oscillations in the profile are not absorbed into the initial section of the process. The structure is a structural tube of welded and painted steel, with polycarbonate protection in a hinged door according to EC regulations, with a stop sensor at its opening and with protection at the entry and exit of the tread. The straps are easily regulated vertically independently by motor reducers with electronic position control. Effective length of 800mm x 100mm bands Rotation direction from right to left or left to right. Speed from 0 mt/min to 40mt/min. 7.4” touch-sensitive screen with control and graphic speed servo torque, control of opening and closure, control of mechanical stop by position with respect to zero, and with a manometer to control clamping pressure. To activate every one of the treads, the equipment has two servomotors with torque control of 1 kW each: The installation of these servomotors allows control plus speed charges. The incorporation of the torque control will allow control by torque graphics which operates in real time in each of the servos. With the touch-sensitive screen security can be incorporated for the drag if one is locked in the extrusion line.
Design and construction of units with tailor-made cuts according to project requirements.
We have 3 types of cut:
As an option all the cut-sets can be supplemented with a collection tray, magnetic tape trailers, reaper…etc depending on the specific project of each client.
Cutting machine to provide a clean and burr-free cut
Precision cutting suitable for soft, rigid profiles, co-extrusions, etc. normally of small dimensions up to 40 x 40mm. Depending on the profile geometry, we guarantee a general tolerance of +/- 0.5 mm x mt. Cutting speed of up to 300 cuts per minute.
1.5 metre rear conveyor belt with adjustable speed for the extraction of parts especially to adapt in-line dies or post operations on the profile.
Dual action encode length control system (positive – negative) eliminates possible variations in measurement due to the vibration of the part.
