Technology 3r3492 demonstration. 3r33548.  3r? 3569. 3r33548.  3r? 3569. We demonstrate the manufacture of products on a compact machine HVC-M. 3r33548.  3r? 3569. 3r33548.  3r? 3569. In the thermal furnace we warm up the silicone form. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r3308. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569. We lay in the form of metal rods to form sufficiently precise holes on the product. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569. We prepare the required number of necessary components (the weight of the filling is 120 grams - for this, 40 grams of component A and 80 grams of component B are required. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569. The mixture is ready for pouring into the mold. We turn the bowl with component B downwards by turning the toggle switch and the components enter the mold through the funnel. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33434. 3r33548.  3r? 3569. 3r33548.  3r? 3569.

Open the vacuum cabinet and place the form in a heating cabinet for subsequent polymerization, which takes about 30 minutes for this material. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569. We received a functional finished product with the necessary surface texture, the color we needed, the necessary physical and mechanical properties, which remained to remove the burrs and the elements of the gating system. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569. 3r33548.  3r? 3569.

Dosage, supply, preparation, evacuation of the mixture and pouring into the form occur automatically in a single node. This scheme allows you to significantly reduce the cycle of filling, that is - 4 minutes in the automatic version, against 12 minutes in the classic. The whole process is reduced by approximately 1.6 times. 3r33548.  3r? 3569. 3r33548.  3r? 3569. Automated injection molding machines:
