the one mould with four cavities pipe making machine can produce four water pipes one time.it can reduce the speed of the single pipe production line.and it can let the product have good cooling effect in production.use the sjsz65 produce,the capacity will easy reach 6 tons / day.
1.way:replaceable die mandrel
2.mold material:45# steel.the inner channel for chrome plating, with strong corrosion resistance.the mould sleeve made of copper alloy.mould heating ring use steel. so it have low power, low energy consumption, stable heating.and it can be used very long.
