In medical device manufacturing, tubing requirements can vary significantly from one application to another. Outer diameter, inner diameter, wall thickness, hardness, flexibility, material grade, radiopacity, surface finish, and secondary processing can all affect the performance of a catheter or minimally invasive device.
Standard off-the-shelf tubing is often unable to meet these highly specific requirements. For medical device manufacturers and procurement teams, working with a specialized custom Pebax medical tubing manufacturer can provide a more efficient way to develop tubing components that match specific product designs.
Kunshan Bova Plastic Co., Ltd. (Bova) specializes in medical Pebax tubing extrusion and secondary processing. Bova focuses on supplying customized semi-finished medical tubing components rather than complete medical devices. This business model allows Bova to concentrate on precision extrusion, material processing, dimensional control, and customized catheter tubing solutions for medical device manufacturers.
Pebax® is widely considered an important polymer family for catheter and minimally invasive medical applications because different Pebax grades can provide different combinations of flexibility, hardness, elasticity, and mechanical performance.
However, choosing a suitable Pebax material is only one part of the tubing development process. The final performance of a medical tube is also affected by its dimensions, extrusion structure, processing conditions, and post-processing.
For example, a catheter component may require:
A specific inner and outer diameter
Tight dimensional tolerances
Thin and uniform walls
A specific Pebax hardness
Different hardness zones or material combinations
Radiopaque additives
Custom colors or identification markings
Tip forming or flaring
Angled or customized tube ends
Special cross-sectional geometries
For these applications, custom Pebax extrusion tubing can provide greater design flexibility than standard tubing products.
Bova provides customized medical Pebax tubing based on customer drawings, specifications, and application requirements.
Bova's dimensional customization capabilities include:
Inner diameter: approximately 0.3–10 mm
Outer diameter: approximately 0.5–12 mm
Minimum wall thickness: down to approximately 0.1 mm
Single-lumen tubing
Non-round and customized cross-sections
Customized dimensional tolerances
Customers can provide the required ID, OD, wall thickness, tolerance, and cross-sectional drawing. Bova can then evaluate the extrusion structure and develop the corresponding tooling.
For suitable projects, sample development can typically be completed within approximately 10–15 days, depending on the complexity of the design and material requirements.
Different medical devices may require different Pebax hardness levels and material characteristics. Bova supports a range of medical-grade Pebax materials, including commonly used grades such as:
Pebax 2533
Pebax 3533
Pebax 4033
Pebax 5533
Pebax 6333
Pebax 7233
Bova can also evaluate modified materials, including formulations containing radiopaque additives or blended hardness requirements.
For applications requiring additional characteristics, customized material solutions can be discussed according to the customer's technical requirements, such as improved anti-blocking behavior or low-temperature performance.
Material selection should always be evaluated according to the final medical device design, processing conditions, and applicable regulatory requirements.
Visual identification can be important when multiple tubes or channels are used within the same medical device.
Bova supports customized tubing colors, including natural, blue, black, and other colors according to customer requirements. Color masterbatch ratios can be adjusted during the extrusion process to achieve the required appearance.
Identification markings can also be customized. Depending on the application, options may include:
Length markings
Position indicators
Reference marks
Custom printed identification
Laser marking
The appropriate marking method can be selected according to tubing material, surface characteristics, dimensional requirements, and intended application.
Precision extrusion is only part of a customized catheter tubing solution. Many medical device components require additional processing after extrusion.
Bova provides various secondary processing services for medical tubing, including:
Tip forming
Flaring
Tube expansion
Beveling
Angled cutting
Customized end forming
Processing can be performed according to customer drawings or technical specifications. Where appropriate, Bova can also work with customers to optimize the geometry of the tube tip or end structure for improved assembly and device performance.
This integrated extrusion and secondary-processing capability can simplify supplier coordination for medical device manufacturers.
Bova uses precision extrusion equipment and process control systems for medical tubing production.
Production equipment includes imported single-screw precision extruders, closed-loop temperature control, and online laser diameter measurement. These systems help maintain dimensional consistency during extrusion.
For applicable tubing designs, Bova can achieve dimensional control such as:
Outer diameter tolerance: approximately ±0.03 mm
Wall thickness tolerance: approximately ±0.02 mm
Thin-wall tubing down to approximately 0.1 mm
Actual achievable tolerances depend on tube dimensions, material grade, cross-sectional structure, tooling, and production conditions. Tolerance requirements should therefore be confirmed during technical evaluation and sample development.
Bova operates its quality management processes according to an ISO 13485-based quality management system and manufactures applicable products in a controlled cleanroom environment.
Quality control covers multiple stages from incoming raw materials through extrusion, dimensional inspection, secondary processing, and final shipment.
Depending on the project, documentation can include material information, dimensional inspection records, and available biocompatibility-related documentation.
For medical device manufacturers, the specific documentation package should be confirmed according to the customer's quality system, regulatory pathway, and product requirements.
Medical device development often involves different production stages, from prototype sampling and engineering verification to small-batch production and volume manufacturing.
Bova supports:
Prototype and engineering samples
Small-batch trial production
Customized production
Volume production
Common-size inventory where available
Standard samples may be available for rapid shipment, while customized tubing projects typically require approximately 10–15 days for development and production depending on project complexity. Expedited schedules can be evaluated for urgent projects.
Bova's business model is focused on medical tubing extrusion and secondary processing rather than complete medical devices.
This distinction is important for medical device manufacturers.
Bova does not compete with customers in the development, assembly, branding, or commercialization of finished medical devices. Instead, Bova acts as a specialized tubing supplier and manufacturing partner.
For procurement and engineering teams, this can provide several advantages:
A focused manufacturing scope allows Bova to concentrate on polymer extrusion, multi-dimensional tubing structures, material processing, and secondary tube forming.
Customers can specify dimensions, materials, hardness, colors, markings, cross-sections, and secondary processing requirements according to their device design.
Medical device companies do not necessarily need to establish their own specialized extrusion line and tooling development capability for every tubing project.
By combining extrusion and selected secondary processing under one supplier, customers can reduce the need to coordinate multiple tubing-processing vendors.
For medical device companies looking for a custom Pebax medical tubing supplier, Kunshan Bova provides a combination of precision extrusion, material customization, dimensional control, and secondary processing.
Bova's capabilities are particularly relevant to applications requiring customized catheter tubing, thin-wall tubing, flexible medical tubing, and other precision-extruded polymer components.
The company supports customized development based on engineering drawings and technical specifications and focuses on supplying tubing components rather than competing in the finished medical device market.
If your project requires a specific Pebax grade, tube dimension, wall thickness, hardness, cross-section, radiopaque formulation, color, marking, or tip geometry, Bova can evaluate the requirements and provide a customized extrusion solution.
