Medical Expansion Device PE Tube Customization Service Guide

I. Diversity of Demands for Customized Expander Tubing

Expansion tubes used in different clinical settings vary significantly in terms of tube diameter, wall thickness design, tip shape, and material properties. Vascular interventional expanders require precise dimensions and extremely high wall smoothness; urological and gastroenterological expanders have larger diameters and specific requirements for support and flexibility. Bova Plastics specializes in providing custom extrusion and tip finishing services for medical PE expander tubes. While not producing finished products, Bova offers flexible OEM customization solutions for various medical device manufacturers.

Customer customization requirements typically include: pipe diameter (Fr number), wall thickness, pipe length, tip angle and length, color and development requirements, and material grade specifications. Bova can provide corresponding solutions for different needs, supporting both small-batch pilot production and stable large-volume supply.

II. PE Expansion Tube Specification Selection Reference

Dilator specifications are typically measured in Fr, where 1 Fr ≈ 0.333 mm. Commonly used clinical specifications range from 6 Fr to 24 Fr, with different departments having varying ranges of commonly used specifications.

Interventional vascular catheters: commonly used are small gauges of 6Fr-12Fr, with thinner walls and a long, gentle taper at the tip.

Urogenital and anorectal tubes: 12Fr-24Fr medium to large sizes are commonly used, with thicker walls and stronger support.

Gynecological dilation products: wide range of sizes, high requirements for surface smoothness.

Bova manufactures PE expander tubes in full specifications from 2Fr to 42Fr, with wall thicknesses ranging from 0.15mm to 1.5mm, and lengths can be precision-cut to order. Customers can customize according to product design drawings, or their technical team can provide selection advice to optimize costs while meeting performance requirements.

III. Full Process Description of Customized Services

Bova has established a standardized customization service process to ensure that customer needs are efficiently implemented. The first step is needs communication, where customers provide drawings or samples, clarifying requirements such as dimensions, materials, precision, and batch size. The second step is technical evaluation, where the process team confirms feasibility and provides a solution quote. The third step is prototyping and trial production, where samples are made for customer confirmation. The fourth step is mass production, where stable supplies are provided according to the confirmed samples.

For newly developed products, we offer small-batch trial production services to reduce customers' R&D risks. We maintain a stock of molds for standard specifications, ensuring fast delivery; for custom-made specifications, the mold-making cycle is short, allowing for rapid response to customer project schedules. All custom-made products are manufactured strictly according to the confirmed samples, guaranteeing consistency in mass production.

IV. OEM Manufacturing Cooperation Model

For medical device manufacturers, Bova offers professional OEM manufacturing cooperation models: clients provide raw materials or specify raw material grades, and we are responsible for the advanced extrusion production and post-processing; or clients provide extruded preforms, and we are only responsible for post-processing steps such as advanced forming. Multiple cooperation models are available to flexibly meet the supply chain needs of different clients.

All collaborations are governed by confidentiality agreements to protect client product design information. The production process is traceable, with production records and inspection reports for each batch of products, complying with medical device quality management standards. Long-term clients enjoy exclusive pricing and limited production scheduling services.
