TZM runner plate structure shape is mainly composed of the distribution of cavity on the mold, the nozzle arrangement and gate location and other factors. TZM hot runner plate according to whether the commonly used can be divided into standard TZM runner plate and non standard TZM runner plate.
1. The standard TZM runner plate there are two types according to the number of cavity, a cavity number is 2 n, 2, 4, 8, 16, 32, 64, etc; Another kind is a multiple of 3, 3, 6, 9, 12, 24 and so on; Standard TZM hot runner runner plate decorated with natural balance port, from the mainstream way nozzle to equidistant from each gate nozzle flow, as long as the corresponding shunt symmetrical arrangement way of the radius of the circular cross section is the same, can realize the balance of each gate nozzle casting.
2. The standard of TZM runner plate is a natural and balanced runner layout, general from the mainstream way nozzle to the flow of each gate nozzle distance is different, different process pressure will cause the difference of melt molding pressure injection point. But by the rheological balance calculation, adjust the radius of the shunt way, also can achieve the balance of each gate nozzle casting.
