Description

APPLICATION

The automatic centrifugal casting machine mod. CNT 400/500 CE Evolution has been studied and manufactured for the production of small and medium size items (such as leather and shoes accessories, costume jewellery, toys, key-holders, medals, buckles, etc.), employing low-melting point alloys (maximum working temperature of 500°C).

PRODUCTIVITY

• 70-110 castings per hour considering medium or large size items;
• 100-140 castings per hour considering small size items.

MAIN CHARACTERISTICS

• Tension: standard V380 three-phase 50Hz. On request all other tensions and frequencies;
• Possibility to employ silicone moulds until maximum diameter mm. 400 (mod. CNT 400 CE Evol.) or until maximum diameter mm. 500 (mod. CNT 500 CE Evol.) and of a maximum total thickness of mm. 120;
• Silk-screen panel of anodised aluminium on which the instrumentation is mounted;
• Electronic instrumentation for a better control of the functioning;
• Centrifugation speed 0-800 rpm controlled by an electronic system; the machine is also equipped by a selector with two pre-set speeds (according with customer request) plus one speed programmable. The electronic system allows a gain in acceleration and braking, further to a lower wear of mechanical parts and less vibrations, as it acts directly on motor power;
• Shielding of the inside electrical panel;
• Plate of increased thickness has been studied and manufactured to avoid deformations due to temperature and pressure;
• Both sectionalising switch and air-cock for pneumatic connection are equipped by predisposition for latch, as per Directives CEE;
• Complete closure of the parts in movement (centrifugation group) by means of an automatic cover regulated pneumatically and equipped with an electronic safety end-travel for immediate stop of the machine, if an advanced opening of the cover occurs;
• “Swan neck”: turned and grinded single casting of pig iron, on which the rotating cylinder and the platens to close the moulds are mounted. It allows to obtain an uniform pressure on the rubber, less vibrations and the consequent improvement of the castings.
