BvU said:How critical is the exact shape of the exit hole ?
And the skewness of the cone -- can it be a straight one ?
AZFIREBALL said:Is G required?
The hole entry should be with 21mm and it should end with 4mm, which deviates 16mm from center.BvU said:Not what I meant: a straight cone has an elliptical exit hole. Since your cone is only slightly skew, the deviation from circular will be small and might be acceptable.
Entrance hole same story.
The axis of the cone is obviously at an angle wrt both vertical and horizontal in the drawing. (Does G really need to be below center ?)
jrmichler said:Two thoughts:
1) Drill a large hole most of the way through, then drill a small hole from the other end at an angle.
2) Make the nozzle by 3D printing. Then you could make a curved hole if you wanted.
Is it important that the hole be tapered?

Material aluminium
Ranger Mike said:I do not think the thread will permit 3D build in a 3D metal printer. Otherwise it could easily be printed in aluminum, steel titanium or Inconel.
you need CAD for it as well. You could print i n aluminum with thread area over size and final machine threads

The material for the nozzle should be selected based on its compatibility with the substance being dispensed, as well as its durability and resistance to high temperatures and pressure. Conducting material testing and consulting with materials experts can help determine the best material for your specific application.
The manufacturing process for a nozzle typically involves designing the nozzle, selecting the appropriate materials, creating a prototype, conducting testing and quality control, and then mass producing the nozzle. It is important to have a detailed plan and follow proper safety protocols during the manufacturing process.
To ensure the nozzle meets quality standards, it is important to conduct regular inspections and testing throughout the manufacturing process. This can include dimensional checks, leak testing, and material testing. Implementing a quality control system and having trained personnel oversee the process can also help maintain quality standards.
The equipment needed for manufacturing a nozzle will depend on the specific design and materials being used. However, some common equipment used in nozzle manufacturing includes lathes, milling machines, drills, grinders, and welding equipment. It is important to have well-maintained and calibrated equipment for accurate and efficient manufacturing.
There are several ways to reduce the cost of manufacturing a nozzle, including optimizing the design to use less material, sourcing materials from cost-effective suppliers, and streamlining the manufacturing process. It can also be helpful to regularly review and improve processes, as well as negotiate bulk discounts with suppliers.
