Tee for flow control - Stainless steel machined parts from lost wax casting ASTM 316 1.4401.
1,Quick Detail:
This is a stainless steel cast part with machined thread, applied in flow control industry.
We offer CNC milling and turning service for custom designed stainless steel parts after lost wax casting. Roughness can reach Ra0.2 for internal hole without polishing. Stainless steel 304, 316, 316L in particular.

2. LOST WAX CASTING PROCESS:

1.TOOL MAKING
A wax injection mold is designed and built to produce castings per customer specifications.
2. WAX PRODUCTION
A wax pattern is produced from the wax injection mold.
3. PATTERN ASSEMBLY
Wax patterns are attached to gating system by hot knife.
4. SHELL MAKING
The pattern assembly is dipped into a ceramic slurry, coated with a refractory material and dried. The process is repeated until the desired thickness and strength is achieved.
5. DEWAXING
Using regulated steam pressure, an autoclave melts and remove the wax from the ceramic shells.
6.SHELL PREHEAT
High temperature ovens cure and preheat the ceramic shells before pouring.
7. CASTING
Pre-heated Ceramic cavities are poured with the molten metal.
8.KNOCK OUT
The ceramic shell is removed by vibration knocking and the cluster is cleaned.
9.CUT OFF
Castings are cut off from the gating system.
10.MACHINING,SURFACE FINISH,AND INSPECTION
After cut off and gate removal, all secondary finishing operations are performed. Each casting is inspected according to customer specifications and requirements.

3. CNC Milling

Our CNC milling process produces custom prototypes and end-use production parts in as fast as 2 days. We use 3-axis milling and 5-axis indexed milling processes to manufacture parts from more than 30 engineering-grade plastics and metals. With machined production parts, you can also get more competitive pricing at higher quantities in addition to first article inspection (FAI) reporting, material certifications, and additional finishing options like anodizing and chromate plating.

How Does CNC Milling Work?
CNC milling is a subtractive manufacturing process. It starts by fixturing a block of metal or plastic material inside the CNC mill. The CNC machine is programmed to rapidly mill out parts from the block of raw material. Our 3- and 5-axis CNC machines are equipped with various toolsets to maximize efficiency and production speed.
Machined plastic parts are left as-milled, which typically means they show visible tool marks. Some metal parts allow more finishing choices like anodizing and chromate plating. When the run is complete and your required surface finish is applied, parts are boxed and shipped shortly thereafter.

4. CNC Turning

Our CNC turning process produces custom prototypes and end-use production parts in as fast as 2 days.

CNC turning process
What is CNC Turning?
CNC turning is a subtractive manufacturing process that rotates a metal rod while a cutting tool is held against the stock to remove material and create final parts.
Our CNC lathes are also equipped with live tooling that can machine flat features and holes into the workpiece. Outside diameter (OD) and inside diameter (ID) threading is also available.
Turned parts can then be left as-machined, with visible tool marks, or bead blasted. When the run is complete, parts are inspected, boxed and shipped shortly thereafter.

Bead BlastSmooth, matte appearance
Anodized

Corrosion-resistant finish. Parts can be anodized in different colors—clear,

black, red, blue, yellow and gold etc.

Powder Coat

This is a process where powdered paint is sprayed onto a part which is then baked in an oven.

This creates a strong, wear- and corrosion-resistant layer that is more durable than standard

painting methods. A wide variety of colors are available to create the desired aesthetic.
