Services
Bankier Companies provides RF heat sealing, heat sealing, and steam sealing services for plastic components and plastic packaging. Our team can help select the right sealing process, develop custom fixtures, refine production settings, inspect finished seals, and support additional assembly and packaging needs.
With experience across several manufacturing processes, we can help move your project from sealing through final production with fewer handoffs.
Discuss Your Sealing Project With an Expert
RF heat sealing, also known as RF sealing or RF welding, uses radio frequency energy to bond compatible plastic materials together. The process heats the materials at the molecular level, creating a strong seal where the surfaces meet.
RF sealing works well for materials such as PVC and polyurethane and can provide consistent seals without relying on adhesives.
The right settings depend on the material, part design, seal area, and production requirements. Bankier Companies can help develop a process that supports consistent results throughout production.
Each sealing process works differently and serves different manufacturing needs.
| RF Heat Sealing | Heat Sealing | Steam Sealing | |
|---|---|---|---|
| How it works | Uses radio frequency energy to bond compatible materials. | Applies heat and pressure to join materials. | Uses controlled steam as part of the sealing process. |
| Best suited for | Compatible plastics such as PVC and polyurethane. | Materials that respond well to direct heat. | Applications designed for steam-based sealing. |
| Key benefit | Creates strong, consistent seals without adhesives. | Provides a direct and efficient sealing method. | Offers another sealing option for specialized applications. |
| Process support | Custom fixtures, process development, and inspection. | Process setup, fixture support, and inspection. | Process setup and production support based on project needs. |
Our team can review your materials, product design, and production goals to help determine which sealing method fits your application.
Material selection plays an important role in seal strength and production consistency.
Bankier Companies works with RF-sealable materials such as:
PVC responds well to RF energy and is commonly used in products that require a strong, consistent bond.
Polyurethane can provide flexibility and durability while supporting strong RF-sealed connections.
Other materials may require a different sealing process. Our team can review your material and application before production begins to help identify the right approach.
A reliable sealing process depends on more than the rf sealing equipment. The fixture must position the material correctly and apply pressure in the right areas throughout each production cycle.
Bankier Companies designs and fabricates custom fixtures and tooling for RF heat sealing and other sealing applications. We consider the part design, seal location, material, and production needs when developing the fixture.
Well-designed tooling can help improve:
Our team can also make adjustments as a project moves through development and production.
Small changes in pressure, heat, timing, material, or part placement can affect the finished seal.
Bankier Companies works with customers to refine the sealing process before and during production. Our team can review the product, fixture, materials, and production requirements to identify settings that support consistent results.
This process can help reduce production issues and create a more repeatable manufacturing approach.
Consistent seals help protect the finished product’s performance and appearance.
Bankier Companies inspects sealed components throughout production to help confirm that they meet project requirements. Our team can monitor seal placement, appearance, consistency, and other agreed-upon quality standards.
If your project requires specific product testing or inspection procedures, we can review those requirements during project planning.
Heat sealing uses controlled heat and pressure to bond compatible materials together. It can provide a simple and effective sealing method for products that do not require RF sealing.
The exact process depends on the material, thickness, seal design, and finished product requirements.
Bankier Companies can integrate heat sealing into your manufacturing or packaging process and provide the setup needed for consistent production.
Bankier Companies also provides steam sealing for applications that use a steam-based sealing process.
Because steam sealing perameters can vary widely by product and material, our team reviews each application individually. We consider the product design, material, sealing requirements, and production needs before developing the process.
Contact our team to discuss whether steam sealing fits your application.
Sealing may be only one step in your manufacturing process.
Bankier Companies offers additional services that can help move products through production without sending them to several different vendors.
Depending on your project, we can also provide:
Working with one manufacturing partner for more stages of production can simplify coordination and keep your project moving smoothly.
RF heat sealing uses radio frequency energy to bond compatible plastic materials together. The energy heats the materials at the molecular level, creating a strong seal without adhesives.
Yes. RF sealing, RF heat sealing, and RF welding are commonly used names for the same type of process. It may also be called dielectric welding.
RF sealing commonly works with materials such as PVC and polyurethane. Material compatibility depends on the specific plastic and application, so our team can review your material before production begins.
Yes. Bankier Companies can design and fabricate custom fixtures and tooling for sealing applications. We develop fixtures around the part design, seal location, material, and production requirements.
The right sealing process depends on your materials, product design, production volume, and performance requirements.
Bankier Companies can review your project, help identify the right sealing method, and support the process through tooling, production, inspection, assembly, and packaging.
