Precision Plastic centrifugal compressor impeller mold
Plastic compressor Impeller Mold Structure
This compressor impelle mold controls the slider's directional movement through structures such as inclined guide pins. Because the slider is designed in layers, it needs to be separated from the product in sequence.
1. Delay mold opening by locking the machine to separate the slider on the fixed mold side from the product first. 2. The mold is opened and the slider on the movable mold side is separated from the product through the inclined guide pin. Only then can the product be ejected smoothly.

As shown in the video, this compressor impelle mold has two core movement steps: 1. Delay mechanism; 1. Delay mechanism; 2. Direction-changing movement of the slider.
Mold design: Precisely match the impeller structure
The impeller of a centrifugal compressor usually adopts a streamlined curved surface design to reduce air resistance and improve compression efficiency. Mold design needs to be modeled through CAD/CAM 3D modeling to accurately restore the complex curved surface and thin-walled structure of the impeller. Design points include:
Parting surface optimization: Ensure smooth opening and closing of the mold to avoid flash or burrs.
Runner system design: Use hot runner or cold runner technology to balance the filling speed and pressure of the molten plastic and reduce product deformation.
Exhaust structure: Use micro exhaust grooves or vacuum assistance to avoid pore defects.
Material selection: Considering both strength and wear resistance
The compressor impeller mold needs to withstand high temperature and high pressure environment for a long time, so the material selection is very important. Commonly used high-performance engineering plastic mold steels include:
P20/H13 pre-hardened steel: suitable for small and medium batch production, moderate cost.
S136 stainless steel: strong corrosion resistance, suitable for impellers with high finish requirements.
Beryllium copper alloy: used in local high wear areas such as cores to improve mold life.
Manufacturing process: precision machining and surface treatment
CNC machining: high-speed milling to achieve micron-level precision of mold cavity.
Electrical discharge machining (EDM): process complex curved surfaces or small holes to ensure no machining marks.
Surface treatment: nitriding, chrome plating or PVD coating technology to enhance mold wear resistance and demolding performance.
Industrial Application and Advantages of Compressor Impeller Mold
1. Application Scenario
Plastic compressor impellers are used in small industrial compressors, pumps or other small industrial applications. Although plastic impellers have advantages such as easy manufacturing and low cost, they may not be suitable for high pressure or high temperature applications.
2. Core advantages of mold technology
Efficient production: One mold with multiple cavities shortens the cycle and reduces the cost per piece.
Material compatibility: Suitable for engineering plastics such as PA66, PPA, PEEK, etc. to meet different performance requirements.
Lightweight design: Plastic impellers are more than 50% lighter than metal ones, reducing equipment energy consumption.
How to choose a high-quality compressor impeller mold supplier?
Technical strength: whether it has mold simulation analysis (such as Moldflow) and rapid mold trial capabilities.
Customized service: whether it can optimize the mold structure according to the impeller working conditions (such as speed, pressure).
After-sales service: provide mold maintenance, repair and upgrade support to extend the service life.
Conclusion:
As the compressor industry develops towards high efficiency, energy saving and lightweight, the technological innovation of compressor impeller mold is crucial. By optimizing mold design, materials and processes, companies can not only improve product competitiveness, but also seize the "technological high ground" of industrial manufacturing.
