BLUE Compressor Valve Plate Advantages
BLUE is an ISO 9001: 2015 certified company with the ability to manufacture high quality compression valve plates.
Our sintered compressor valve plates have high mechanical strength and good durability.
Our sintered compressor valve plates have a sintering density of more than 6.7g/cm³ and excellent wear resistance.
The compressor valve plates produced by BLUE are blackened and have good rust resistance.
Why use Steam Treatment?
Steam treatment, also known blackening, exposes sintered iron parts to high-temperature steam, forming a Fe₃O₄ oxide layer on the surface.
This process seals the holes of compressor valve plates, improving air tightness and allowing them to withstand gas pressures of 1.5-3.0 MPa without leakage.
In addition, blackening enhances the valve plate’s hardness and corrosion resistance.
Why use PM to Manufacture Valve Plates?
Cost-effectiveness
Compared with machining, the powder metallurgy process requires fewer steps and consumes less energy, making it more cost-effective for large-scale production.
Part to part consistency
Powder metallurgy compressor valve plates have high quality consistency from batch to batch
Precision manufacturing
PM can produce valve plates in near-net shape, thus reducing subsequent machining.
What is a Compressor Valve Plate?
Compressor valve plates are important parts of compressors, commonly used in refrigerators and air conditioners. They have the following functions:
Regulating Refrigerant Flow
They control the intake and exhaust of refrigerant gases, ensuring efficient compression and circulation within the system.
Sealing Compression Chambers
Valve plates provide a seal that maintains the necessary pressure differentials during operation, preventing leaks and ensuring optimal performance.

Powder Metallurgy Manufacturing Process
Powder metallurgy is a precision manufacturing process with a continuing and stable accuracy of up to 0.01mm, which requires strict control at each stage to ensure the quality of the final part. Any deviation or error during the process may result in the rejection of the entire batch.
Designing
Mold design is a critical process that must consider the desired part geometry, material properties, production volume, and cost-effectiveness.
Tooling
Powder metallurgy tooling includes upper and lower punches, die, and core rod. The mold needs to have excellent strength, hardness and wear resistance.
Mixing
Mixing is the process of blending metal powder with binders to improve its uniformity and fluidity, promoting better material consistency.
Compacting
Conpacting is a process that presses metal powder into mold cavity through powder compaction machine to get a green compact part.
Sintering
Sintering heats the green compact to a temperature below its melting point in a controlled atmosphere to obtain the desired mechanical properties.
Sizing
Sizing corrects dimensional deviations after sintering and enhances product accuracy. It requires an additional, simpler set of molds compared to the forming mold.
Machining
Machining can achieve complex shapes that cannot be pressed by powder metallurgy, such as transverse holes and screw threads.
Tumbling
Tumbling removes burrs and flash from a part's surface by vibrating it with abrasive media, such as stone or ceramic, resulting in a smoother finish.
Blackening
Blackening process, or steam treatment, forms an oxide layer to prevent rust and increase hardness, offering a cost-effective solution.
Hardening
Hardening enhances the material's strength and hardness through carburizing or nitriding, resulting in improved wear resistance and fatigue life.
Inspecting
The inspecting process is always a critical step that ensures quality and performance through BLUE inspection standards before shipping.
Packaging
BLUE's packaging process uses anti-rust paper, vacuum, blister and other methods to ensure that the product is intact during transportation.
