Jamnagar makes almost every type of small and medium brass component. The main groups are plumbing and sanitary fittings, electrical parts, inserts and fasteners, valve and gas parts, and custom turned or forged parts made to your drawing.
Most units specialise. A shop that makes fine electrical pins on sliding-head lathes is rarely the right choice for heavy forged valve bodies, so match the part family to the supplier early.
The main product families
- Plumbing and sanitary fittings, such as elbows, tees, unions, nipples, compression fittings and tap bodies.
- Electrical parts, such as terminals, connectors, plug pins, earthing parts and neutral links.
- Inserts for plastic moulding, with knurled, threaded or heat-set designs.
- Fasteners, such as screws, nuts, studs, washers and spacers made from brass rod.
- Valve and gas parts, such as ball valve bodies, spindles, gas regulator parts and LPG fittings.
- Hose and pneumatic fittings, such as barbs, couplings and push-fit bodies.
- Automotive and instrument parts, such as sensor housings, fuel line fittings and gauge parts.
- Custom turned, milled or forged parts made to a buyer's drawing.
How the part is made decides the supplier
Small round parts are usually turned from bar on cam-type automatics or CNC lathes. The process is described in what a turned component is. Parts with thick walls or complex outer shapes, such as valve bodies, are usually hot-forged first and then machined.
Large or hollow shapes that cannot be forged may be sand-cast or gravity die-cast. Castings carry a higher risk of porosity, so ask how the supplier tests for leaks if the part holds pressure.
Finishing is often done outside the turning shop. Electrical parts may be tin- or silver-plated, and sanitary parts are usually nickel-chrome plated. Confirm which plating unit is used and how plating thickness is checked.
Other metals
Many Jamnagar shops also machine copper, stainless steel and aluminium on the same machines. Whether they do it well is a separate question, covered in stainless and aluminium parts from Jamnagar.
What to send when you ask for quotes
Suppliers quote faster and more accurately when the enquiry is complete. A photo and a rough size are rarely enough for a fair comparison.
- Send a dimensioned drawing with tolerances, ideally with a 3D model for complex shapes.
- State the alloy and the standard it must meet, not just "brass".
- Give the finish, plating type and minimum plating thickness.
- Give the annual volume, the batch size and how often you will order.
- Name any market rules the part must meet, such as drinking water or RoHS limits.
- Describe the packing you need, including bag counts and labels.
