Smart Molding International 1-2021

40 smart_molding international 1/2021 periphery G-Max 13 beside-the-press granulator The G-Max 13 completes the existing G-Max granulator series from WITT - MANN, which offers cutting chamber sizes ranging from 130 × 260 mm to 460 × 235 mm and engine outputs from 2.2 kW to 4 kW. The models from the G-Max series can be used for ma - terial throughputs of up to 50 kg/h on injection molding machines with up to 500 t clamping force. The G-Max 13 granulator is suitable for in-line recycling of soft to medium hard sprue consisting of PP, PE, ABS or PU, and can be used on injection molding machines with clamping forc - es of up to 230 tons. The material screens of the G-Max 13 are available with screen per - foration in different sizes: either 4 or 5 mm in diameter. This ensures suitability for varying materials and throughputs. The perforations in the screens have a conical shape, so that soft and sticky granulate can pass through more easily. A feature which ultimately contributes to minimizing the accumulation of material deposits in the openings. The tiltable material hopper simplifies cleaning and servic - ing of the appliance enormously. For instance, a screen change can be car - ried out without tools, and the time required for servicing is reduced to a minimum. The granulator has an open rotor with three knives. It is designed with openings between the knives and the rotary axis to ensure unhindered ven - tilation of the cutting chamber. Thanks to this type of design, this model is ideally suited for grinding materials which are sensitive to heat or parts not yet completely cooled. Exchang - ing knives is extremely easy and com - fortable. The new G-Max 13 can handle a material throughput of up to 35 kg/h (depending on the shape of the parts/ sprues, screen size and quality of mate - rial), it operates with a low noise level and is extremely energy-efficient. CARD – small dryers with a great effect The new compressed air dryers from the CARD series have been an integral part of the WITTMANN prod - uct portfolio since April 1 of this year. The first few months have shown that, in spite of the great variety of differ - ent models and sizes, three types of appliances have become particularly popular. These are the sizes CARD 6G/FIT, CARD 10S and CARD 20S. On these appliances, the desired drying temperature can be set via a touch After this year’s FAKUMA has been canceled, WITTMANN decided to presents the exhibits originally planned for the show by way of product videos, and to upload them on “Virtual Fakuma”. The presentation of the videos is intended to take place primarily in personal meetings with customers. To present the product highlights as vividly as possible to a wide audience, the product videos will also be made available on the company’s YouTube channel.
