In-line Thermoforming Machines The in-line thermoforming machines are dedicated to the production of refrigerator inner doors and liners . The machines are available in various configurations depending on the Client's production requirements. All thermoformable materials used in the refrigerator sector, such as ABS, PS and HIPS can be processed on our systems. Our in-line thermoforming machines are designed to meet the highest standards in quality and production. The systems are subdivided into different working stations to guarantee elevated productivity and process repeatability. Infeed of either sheet or coils is carried out in automatic mode and the handing of the material in the various work stations is carried out using "forward/reverse" gripper or chain conveyors. The moulding station can use the various known forming technologies: with blow box " Bubble Blow Vacuum forming ", with a balloon obtained by blowing air from the blowing box; with universal bell moulding " Snap-Back Vacuum Forming ", with a balloon obtained by applying a vacuum from a universal bell; or with a nominal bell " Vacuum-Pressure Forming " using a particular combination of mechanical moulding, vacuum and pressure. Single Station Thermoforming Machines The Single station thermoforming machines are designed and built to the requirements of various production sectors , for small and medium productions of thermoplastic materials with thicknesses ranging between 1 mm and 10 mm; with no limits to the outer dimensions. The machines are available in various configurations according to the production requirements of the Client, the material to process and the requested productivity. All thermoformable materials , whether casted or extruded, can be processed in our systems. The processed material is subject to plastification and moulding in the same work station, using heating panels, positive and negative moulds and the use of vacuum. Our single station thermoforming machines are designed to meet the highest standards in quality and production. The systems are "configurable" to guarantee productivity and process repeatability. The base model of the single station thermoforming machine is supplied by manual loading and unloading. There are several solutions to automate the loading/unloading process of the moulded piece, such as the lateral "come and go" device or the one with perforating chain conveyors. Thermoforming Moulds The Thermoforming Division produces small, medium and large thermoforming moulds to mould thermoplastic materials. The moulds are used in the most various fields of application, such as the automotive, appliance, medical, sanitary and tertiary sectors. The moulds can be equipped with tools to improve and make the moulding phase easier, such as: dedicated reduction frames, plug assist, and both nominal and universal bells. The thermoformed moulds are produced based on the required thermoforming technology: vacuum or vacuum and pressure. The Thermoforming Division puts its several decades of experience at the disposal of the Client, to offer consultancy, research and development service aimed at drawing up a project, which fully corresponds to Client requirements. All of the phases involving research, design, construction, of both the wooden model as well as the finished mould, and final inspection, are carried out in our facilities by highly specialized personnel. The research and design of the thermoforming moulds is carried out with the use of the most advanced computerized three-dimensional CAD-CAM systems. The Thermoforming Division is equipped with dedicated tools to build moulds, and a department where custom processes are carried out on dedicated 3- and 5-axis CNC machines and CNC lathes, with routes generated with the use of the most modern three-dimensional CAD-CAM software. The moulds are made from aluminium casting, or starting from aluminium billet, with a pipe countersunk into the casting for temperature control. The moulds can also be made with alternative materials such as epoxy resins, especially suited for pre-series and prototyping. Depending on the application, the moulds can integrate moving parts for undercuts. Punching and Trimming Machines The punching and trimming machines for thermoformed pieces are designed and built to be used mainly in the appliance industry and to obtain a product that meets Client requirements. The punching and trimming machines for thermoformed pieces have either a "Stand Alone" configuration or an integration inside the "In Line" thermoforming machines. The machines can be equipped with either manual or automated loading/unloading of the thermoformed piece. The punching and trimming machines for the thermoformed piece, with “In Line” integration, are installed at the point where the thermoformed piece is unloaded from the forming station. In this configuration a manipulator handles the thermoformed piece in the various trimming and punching stations. The punching and trimming machines for the thermoformed pieces, with "Stand Alone" configuration, are configured with dedicated solutions depending on the request of the Client: perimetral trimming, separation or punching cut, or with integrated solutions, with automated units to transfer the thermoformed piece from one station to the next.
