Plastic Manifolds a Boon for Medical Devices
Key takeaways:
- Plastic manifolds play a crucial role in enhancing fluid and gas control in medical devices, all while minimizing leak points and simplifying system design.
- When it comes to medical-grade plastics, materials like PVDF, PTFE, and polypropylene stand out for their impressive chemical resistance and low risk of contamination.
- Unlike metal, plastic manifolds are not only lighter but also resistant to corrosion, making them ideal for sterile environments.
- The design of integrated plastic manifolds streamlines assembly and optimizes flow paths in compact medical systems.
- Additionally, custom plastic manifolds can help reduce manufacturing costs without compromising on reliability and performance standards.
Companies that produce medical devices should consider the benefits of using components that utilize plastic manifolds. Plastic manifold transportation systems provide a continuous supply of gas and chemicals that can be used in a variety of applications.
Manifolds: Simple and complex manifolds can be produced in both stainless steel and several types of plastics. The design and fabrication of plastic manifolds depends upon the application and often must be developed to meet any strict quality specifications and criteria required by a given industry.
Plastic manifolds can be used in the production of medical equipment such as lab accessories, patient monitor devices, diagnostic instruments, operational machinery and many more applications. The life science and semiconductor industries have a huge dependence on manifold delivery systems.
Your goal should be a reliable, simplified system that delivers a consistent, highly-repeatable performance, with the flexibility of having sub-systems that have the capability of multiple flow rates and pressures. Plastic manifolds can deliver those results, and some plastic options even offer better insulation than some metal manifolds.
Advantages of plastic manifolds
There are several benefits to using plastic manifolds, including cost savings, space savings, fewer leaks, and easier maintenance. Among these benefits, the cost savings associated with assembly and installation, as well as the reduction in space requirements are the most significant.
Some of the benefits of making the switch to plastic manifolds include:
- High thermal mechanical strength: Some plastics are able to resist thermal degradation and maintain operating strength and rigidity in high temperatures.
- Plastic manifolds have good chemical resistance to acids, alkalis, greases and solvents, hydrogen peroxide, demineralized water and hot steam.
- Minimal outgassing (gas release within solid material) under vacuum: This is especially important in the medical device industry as maintaining a sterile environment is essential.
- Good creep and chemical resistance.
- Plastic manifolds have minimal thermal expansion.
- Good wear resistance.
- Good plasma resistance for reduced corrosion.
Our technicians have decades of experience in plastics fabrication. Some of the common plastic types we can use for your next project include:
Polyvinylidene Fluoride (PVDF)
PVDF is a high-purity plastic that is commonly used to produce semiconductor equipment components. Its excellent chemical resistance makes is a good choice for medical devices or life science industries. It is flame- and abrasion-resistant and offers a clean construction option for manifold systems. Piping, fittings and valves are often made with PVDF.
Polytetrafluoroethylene (PTFE/PFA)
PTFE/PFA is a low-friction plastic that is easily formable and boasts great resistance to chemicals. It works well in varying temperature environments, making it a good choice for semiconductors used in a variety of industries.
Polypropylene (PP)
PP is a durable plastic also used in semiconductor industries as it has the benefit of low moisture absorption. Its chemical resistance is good, though PTFE and PVDF offers a stronger performance there.
High Density Polyethylene (HDPE)
HDPE is a strong, light, and chemically resistant plastic that is used in construction projects.
Our plastic manifolds are customized to your specifications, tested in-house and delivered to you ready to be installed into your existing production area.
