Silicone Nozzle

Silicone Nozzle

Product Description

Silicone Nozzle, which is also called silicone rubber spray shower nozzle spout tip, Mainly used in sanitary products, purifier and cosmetic as elastomer rubber water nozzles, misty spray, air blast mouse (sometimes also called valve). Our Rubber Bath Rubber Shower Head Nozzle are produced to meet the latest standard, therefore they offer better guarantees of resistance and sealing power. Xiamen Better Silicone Co., Ltd is specialized in making mold tooling and manufacturing silicone rubber products.

We expanded into the producer of a variety of rubber silicone products and mold tool, rubber tube, seals, gaskets, vulcanize joining ring gasket, vent sealing gasket, sewer pipe gasket, grooved gasket, lighting gasket and so on. Applying to bathroom, auto part and other mechanical uses.

4. Application

In water products, elastic silicone rubber nozzles mostly use in shower head nozzles, faucet, tap products, sprinkler etc. Mold making, silicone rubber nozzle burr control, and nozzles structure will key to water or air spray splash effects.
5. Silicon Rubber Nozzle Mold tooling Making:
For better silicone rubber water nozzles, making mold tooling for need three layers mold plates and also need punch needles. Some need four layers mold plates for under-cut nozzles.
Machines holes in mold plate by WEDM-LS for assembling the punching needles. Each holes spacing mostly above 0.5mm. Installing the punching pin, need think of the nozzles structures etc.

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 shower head spray.
If even one nozzle have quality problem, the mold tooling can’t revive and reuse.
That is the reason why different suppliers mold tooling cost for silicone rubber water nozzles is big different.

7. 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.
