Stainless Steel Casting of Marine Boat Hand Rail End Fitting

The hand rail end fitting is a kind of stainless steel fitment for marine boat tubing or pipe in different diameters. Same as other stainless steel marine boat hardwares, it is investment cast from heavy duty 316 marine grade stainless steel alloy.

Stainless Steel Casting Manufacturing Process

Stainless Steel Casting of Marine Boat Hand Rail End Fitting

Stainless steel casting for marine boat hand rail end fitting is a stainless steel lost wax casting process, which can cast the hand rail end fitting in one piece without additional welding. Cast from heavy duty 316 marine grade stainless steel, the hand rail end fitting is quite sturdy and durable, which last a long time. Compared to 304 stainless steel, 316 stainless steel hand rail end fitting can achieve maximum corrosion resistance and durability in the saltwater environment.

Stainless steel casting, a good option for metal parts requiring good strength and corrosion resistance, can creat near-net shape stainless steel products successfully in various shapes. Although the introduction of other materials and manufacturing techniques were introduced in the last few years, there is no such a material can replace stainless steel in lost wax investment casting technique. The mature stainless steel manufacturing method, fast delivery and impressive after-sale service make CFS a good stainless steel foundry in China.

Then, how does stainless steel casting work? The stainless steel casting of marine boat hand rail end fitting begins with the create of a wax pattern, which has the same shape with the desired part. Due to its good size accuracy in recreating parts with precise tolerances, it is also referred to as investment casting. Therefore, the stainless steel casting process in CFS Foundry is the investment casting process in different stainless steel alloys. Once the wax patterns are ready and mounted as an assembly, the whole assembly is coated with sand and dipped into slurry to form a protective coating. Hardening the coating and forming a ceramic shell by dewaxing. So, lost wax casting is named as the liquid wax leaks during dewaxing process.

Next, pouring liquid stainless steel through sprue gate until its fills the cavity of the shell. After solification, cut off the shell to achieve solid castings. Finally, removing the excess material to have net shaped hand rail end fitting.

Using stainless steel investment casting, instead of sand casting methods comes with several advantages for marine boat hand rail end fittings:

  • The marine boat hand rail end fittings are precise and exact copies of the original.
  • The casting process also ensures consistency and reduces costs for both time and labor.
  • You’ll receive precision boat hand rail end fitting at a lower cost.
  • The surface finish of investment cast stainless steel marine boat hand rail end fitting is far superior to that of sand casting method.
  • Besides hand rail end fitting, other marine boat fittings could be produced by stainless steel casting method as well.

Mirror Polished Finish

Although the surface of cast stainless steel marine boat hand rail end fitting is not rough, but it is not shinning. To have a smoother and shinning surface, mirror polishing is always applied to improve the surface quality. This kind of surface finishing way is popular for dealing with various types of cast stainless steel marine hardwares. Normally, to achieve the mirror like finish, the parts need to be polished several times, and it is time consuming. Of course, additional cost will be added.

As a comprehensive stainless steel casting supplier, CFS Foundry can deal with both stainless steel casting and mirror polishing. If you have any inquiry on stainless steel casting and mirror polishing of marine boat hand rail end fittings, pls get in touch with us!
