How to choose the material of Cartridge Filling Machine

When choosing the material of Cartridge Filling Machine, it is necessary to consider multiple dimensions such as material properties, production environment, and equipment durability to ensure safe and efficient production. The following are the specific points:
1. Material contact parts
The material of this part directly affects product quality and equipment life. The food and pharmaceutical industries must use 316L stainless steel that meets FDA and GMP standards. It is corrosion-resistant, easy to clean, non-toxic, and can withstand high-temperature sterilization; when handling highly corrosive materials such as strong acids and alkalis, polytetrafluoroethylene (PTFE) lining or titanium alloy materials are required; for high-viscosity materials, ceramic filling heads and plungers have strong wear resistance and can reduce material residues.
2. Transmission and structural components
For non-material contact parts such as racks and guide rails, 304 stainless steel or aviation aluminum can be selected to take into account both strength and rust resistance; for transmission parts such as gears and screws, it is recommended to use carburized hardened steel, which has high hardness and wear resistance, and can ensure long-term stable operation.
3. Seals and consumable parts
The material of the seal determines the anti-leakage performance of the equipment. The food and pharmaceutical industries give priority to the use of FDA-grade silicone rubber, which has a wide temperature resistance range and is non-toxic; when the chemical industry comes into contact with organic solvents, fluororubber (FKM) must be used, which is oil-resistant and resistant to swelling; under special working conditions, polyetheretherketone (PEEK) can be selected, which has both high strength and chemical stability.
4. Environmental adaptability
In humid and dusty environments, the equipment housing and exposed parts must be made of stainless steel or materials treated with anti-corrosion coatings; in high-temperature environments, choose high-temperature resistant alloy steel or ceramic-based composite materials to ensure that the equipment performance is not affected
