Design Solutions For Stainless Steel Handrail Tube Fittings

A glass stair railing design without an experienced manufacturer to deliver proper solutions can end up being costly.

There are various machining requirements:

  • Lost was casting, cold forging.
  • Cold forging.
  • Metal sheet forming.
  • Punching
  • Welding
  • Bending

Choosing suitable manufacturing solutions is critical and Unity Metal is good at it.

Stainless Handrail Tube Fittings Process

1. Die Design of Stainless Steel Railing Kits

Team of dedicated professionals at Unity Metal works closely together with their customers from the design stage through final qualification ensuring that both the die and final product meet all of their requirements.

The handrail accessory designers work with their die makers throughout the design and fabrication of the die using the latest industry-standard software. Computer-Aided-Manufacturing (CAM) is capable to read data files and generates complex molds efficiently assists in providing accurate, low-cost injection molds.

Our engineers help to determine the cast-ability of the stainless steel railing kits design, and suggestions may be made to improve casting design or performance. The engineers are also fully conversant with production processes, and their presence in the factories provides continual support during production.

No matter what your source drawing is, our engineer can transform your drawing into a solid model. This solid drawing enables you to see the final profile of stainless steel railing kits.

2. Wax Pattern Making – Injection Of Melted Wax

Wax replicas of the desired castings are produced by injection molding using a metal die, Melted wax is injected into the die, creating an exact wax replica of the part.

One wax pattern must be injected for every finished part. In the case of a prototype, a heat disposable pattern is generated using a CAD file.

3. Wax Pattern Assembly

The casting process begins by producing a wax pattern employing a precision mold. The wax patterns are fastened by the gate to a runner to form a cluster. The cluster is dipped in refractory slurry and coated with fine sand then dried.

The process of dipping and drying is repeated until a robust thickness is achieved. After this, the ceramic shell is heated, and the wax is melted away. These patterns are attached via a “gate” to a central wax stick, referred to as a “tree” or “sprue”, to form a casting cluster or assembly, and mounted on a pouring cup.

4. Shell Buiding

A shell is built by immersing the assembly in a liquid ceramic slurry and then into a bed of extremely fine sand. Several layers may be applied in this manner.

5. Dipping & Drying

The process of dipping and drying is repeated until a robust thickness is achieved. After this, the ceramic shell is heated, and the wax is melted away. This leads the mold into a cavity that can be filled with the molten metal.

6. Dewaxing

The hollow mold is fired, and the liquid alloy is poured into the pre-heated mold.

After the metal has solidified,the slurry shell is broken off and the individual part is cut away from the connecting gates. The parts are cleaned and subjected to further secondary operations.

7. Melting & Pouring

The shell is filled with molten metal using various techniques:

  • The Metal cools.
  • The parts.
  • The gates
  • Tree and pouring cap becomes a solid casting.

8. Knock Out & Cleaning

When the metal has cooled and solidfied, the ceramic shell is broken off by vibration or water blasting.

A metal melt casting apparatus comprises a vessel for containing the melt and having a wall portion having a downwardly pointing melt tapping hole, the vessel tilting so that this wall portion can be raised and lowered.

A fountain has a top for receiving the melt when registered with said tapping hole and a bottom for connection with the bottom of a mold.

A gas-tight elastically deflect sealing means interconnects the tapping hole and the fountain top when the mentioned wall portion is lowered thereon by tilting of the vessel.

The sealing means is made in the form of two parts which elastically flexibly engage when the converter wall with the tapping hole is lowered on the top of the fountain, one part being connected to the wall and the other part being connected to the fountain.

The sealing means is provided with a gas passage so that the tapping metal stream may be subject to evacuation for degassing or surrounded by an inert gas.

9. Cutting

The parts are cut away from the central tree using a high speed friction saw.
