Valves, as the key to gas and fluid control
Xintai Valve Group
As a modern professional manufacturing company specializing in valve design and manufacturing
Craftsmanship and craftsmanship create excellent quality
Next, we will unveil the mystery of this craftsmanship for you
Wax injection

Before production, we make wax molds based on the model as internal molds for the castings
To improve efficiency and accuracy, we adopt automated wax injection technology
Accurately control the injection of wax to ensure the quality of wax molds
wax repair

The workers in the wax repair process will carefully inspect the wax mold
Correction and inspection to ensure that the shape and size of the wax mold meet the design requirements
Group tree
Tree assembly refers to the process of using qualified wax molds that have undergone quality inspection
Assemble onto the mold head and create a complete pouring system - commonly known as a tree string
shell making

The shell making process mainly includes dipping and sanding
Our entire shell making process
All are automated production lines, with 7-8 layers of sanding frequency
Strive to achieve the best sand shell effect
After sanding, the sand shell should be naturally air dried
Dewaxing (steam dewaxing)
The steam dewaxing process completely removes the wax model,
Prepare for the subsequent casting process
Mold shell roasting

The main purpose is to provide sufficient strength to the mold shell through high-temperature treatment
And stability to withstand the pouring of subsequent metal melt
Pre furnace inspection

Pre furnace testing is an important step before casting
The main purpose is to inspect the quality and composition of raw materials or semi-finished products
Ensure that they meet the casting requirements
casting

Casting is the core step of casting,
Including melting metals, slag removal, preheating sand shells, and injecting molten metal
This process requires meticulous operation to ensure the quality of the castings
The casting process is completed after the metal melt cools and solidifies
Seismic shell
By using the vibration of the shaking machine to remove the sand shell,
Ensure the integrity and stability of castings
shot blasting
Shot blasting is a mechanical surface treatment process,
Removal by high-speed rotating shot blasting machine
Surface impurities on the workpiece improve surface quality and enhance material properties
Seiko

The final precision process is a crucial step,
The purpose is to remove surface defects from semi-finished valve products
Burrs, oxide scales, etc. can improve the surface smoothness and accuracy,
To ensure the sealing and service life of the valve
finished product

After the casting process is completed, assemble the semi-finished valve products
All valve products undergo strict quality inspection and pressure testing before leaving the factory,
To ensure that its performance and quality meet the standards
There are eight production lines in the casting base
Capable of meeting the diverse casting needs of various customers, with an annual output exceeding 12000 tons
It can produce more than 30 tons of products per day. Mainly serving oil and gas
Chemical, power plant, metallurgy, national defense, water conservancy engineering, pharmaceuticals and other fields
We have always adhered to the responsibility of revitalizing national industry and promoting the spirit of scientific and technological innovation
To provide better products and services for both new and old customers
