- Pore size/porosity: microporous (several micrometers to several hundred micrometers) or uniform porous structure
- Protection/sealing level: Depending on the design, it can reach IP54 (dustproof, splash proof) or higher
- Optional: High temperature resistant material, chemical corrosion resistant formula, stainless steel shell composite, with drainage holes or anti blocking design
Production process of plastic pneumatic muffler
Select engineering plastic particles or modified materials containing fillers that meet the requirements.
Produce the outer shell and inner core through injection molds (if there is a porous structure, special molds or post-processing can be used).
If microporous or sponge cores are used, they may be obtained through sintering, foaming, or injection molding.
deburring, surface finishing, tapping (if internal threads are required), ultrasonic welding or bonding of composite components.
Install the filter element, sealing ring, connecting piece, etc. and fix them.
Air tightness test, pressure resistance test, noise attenuation performance test, flow/pressure drop test, appearance inspection.
Clean and dry if necessary, package and label according to customer requirements for shipment.
Batch records, factory inspection reports, and optional performance reports.
Advantages of plastic pneumatic muffler
Corrosion and acid alkali resistance
More resistant to certain chemical media than metal parts.
Lightweight and low-cost
Low material and processing costs, easy to replace and apply in large quantities.
Good sound insulation effect
It significantly attenuates airflow noise and reduces system vibration.
Diversified customization
Sizes, threads, materials, and filtration performance can be customized as needed.
Easy installation
Standard thread or plug-in design, easy to replace on site.
No spark risk
Plastic materials are suitable for low-risk environments around flammable gases (but attention should be paid to high temperature environments).
Easy to maintain
It can be designed with a removable or replaceable filter structure to extend its service life.
Application of plastic pneumatic muffler
Pneumatic system
cylinder, valve, pressure regulating valve, exhaust port noise reduction and filtration.
Compressor and vacuum pump
exhaust silencing and particle interception.
Automated equipment and assembly lines
reduce on-site noise and improve working environment.
Medical equipment and laboratory instruments
Low noise, clean requirements (choose materials and cleanable designs).
Food and pharmaceutical industries
Use silencers made of food grade or washable materials.
Automotive industry
pneumatic control components, workshop equipment, and contour cutting machines, etc.
Semiconductor and electronic manufacturing
Choose appropriate materials and treatments when there are special requirements for particles and cleanliness.
Selection and usage suggestions
- Select the model based on the caliber and flow rate, and pay attention to the pressure drop curve and maximum flow rate.
- Choose high temperature/corrosion resistant materials or metal composite types for high temperature or chemical medium applications.
- When there is a risk of blockage, choose removable or large aperture and maintain regularly.
- Keep the exhaust port unobstructed during installation to avoid damage to the seals caused by reverse installation or excessive tightening.
- For occasions with high requirements for noise, multi-stage or higher attenuation design can be chosen, and combined with pipeline vibration reduction measures.
