Tee for flow control - Stainless steel machined parts from lost wax
casting ASTM 316 1.4401.
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:
A wax injection mold is designed and built to produce castings per
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.
Using regulated steam pressure, an autoclave melts and remove the
wax from the ceramic shells.
High temperature ovens cure and preheat the ceramic shells before
Pre-heated Ceramic cavities are poured with the molten metal.
The ceramic shell is removed by vibration knocking and the cluster
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.

Corrosion-resistant finish. Parts can be anodized in different
black, red, blue, yellow and gold etc.
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.
