Product Description

Mold Tooling for Silicone Rubber Shower Head Nozzles:

1. For save Molding Tooling process cost or less experience, many suppliers choose milling the mold steel for forming the needles to produce silicon shower head nozzles.
That just two mold plates without any punch needles.
When test mold tooling samples or trial production, they are difficult to find the burring in the silicone nozzles.
However, that will affect the silicone shower head nozzles quality when mass production.
The mold tool will wear as the production quantity increase, the silicone burr in nozzles will become more and more big.
The burring in silicone nozzles will affect the function and effects of showerhead spray.
If even one nozzle have quality problem, the mold tooling can’t revive and reuse.

2. Actually, the mold tooling for silicone shower faucet gaskets: Punch Needles, two mold plates (some time need three mold plates).
That need wire cutting the hole in the mould tool for installing the punch needles. And the wire cutting must choose the low-speed, even low-speed wire cutting process cost is expensive.
When silicone shower head nozzles appear burring, we can just dismantle the punch needles or directly change the new punch needles.
That can make sure each nozzle quality when mass production, and also can save production time and the mould tooling maintenance cost.

That the reason why different suppliers mold tooling cost for silicone handshower faucet nozzles is big different.

The influence of shower head nozzles to the water flow:
·      As the terminal of the shower head, the size and structure of the nozzles make a great influence on water flow capacity. There are three kinds inner hole of nozzles: round hole, rectangle hole, triangle hole and so on. However, the spray shape of the round hole is much better than the other two types. Under the same Reynolds number, as the sprayer of round nozzles tends to flows along the center line, the possibility of second flow is less,
·      The shower head nozzles have some structures, like thin-walled orifices(a), extended cylinder nozzles(b), inserted cylinder nozzles(c), shrink cone nozzles(d), expanded cone nozzles(e), and streamline nozzles.
·      The most common structure of nozzles is extended cylinder nozzles(b).
1.       Compare with extended cylinder nozzles, because the flow disturbance in the entrance area is increased, under the same flow capacity, the flow rate of inserted cylinder nozzles is slow.
2.       The water outlet area is smaller than the water inlet area, the flow speed of inserted cylinder nozzles is slow than extended cylinder nozzles
3.       The water outlet area is bigger than the water inlet area, the flow speed of inserted cylinder nozzles is fast than extended cylinder nozzles
4.       As will not form no vacuum and have not suction force, the flow capacity of streamline is also not maximal.
