SHARE's capabilities to create the final product for medical applications involves more than just having precision fabric on the roller. We have many necessary finish process steps for medical fabrics including cleaning, heat treating, calendering, dyeing and coating.
We process our fabrics to become "application-ready" by cutting, stitching, gluing, welding, laser cutting, molding and more, all are tailored to meet medical specifications. We create a wide selection of forms for medical application from fabric ribbons and stamping pieces to cylindrical filters and precision plastic molded filter with smooth surface and high flow rate.
All these processing steps for medical parts are manufactured under strict cleanliness control standards and are processed in our clean room.
At SHARE, we produce filter materials characterized by precise mesh openings, open area and mesh thickness by ourselves. The most commonly filter material are the following:
Polyamide mesh (Nylon): Resistance to acids is limited and dependent on the concentration and temperature. Excellent resistance to alkalis, including caustic soda and caustic potash. Chemical performance against organic solvents is very good. Temperature resistant from 0 to 115 °C when dry, 95 to 100 °C in water.
Polyester mesh: Resistant to most acids. Not resistant to alkalis. Temperature resistant from -75 to +150 °C (for short periods), up to 135 °C for longer requirements.
PP mesh: Humidity resolution at 95% rel. air moisture and 25 °C is less than 0,01%. Resistant to alkalis, even in high concentrations. Use with organic solvents is limited. Temperature resistant from 0 to +100 °C (for short periods), up to 90 °C for longer requirements.

SHARE Converting Capabilities
1. Laser Cutting
Laser cutting produces highly precise fabric parts with a heat-sealed edge. Share uses different laser cutting systems to meet customers various requirements including semi-automated vision systems and fully automated with AI programming.
2. Heat Slitting
Heated knives are used to create fabric strips/ribbons for much many applications such as injection molding to diagnostic test strip, and hot-cut mesh edges are melted to enhance durability. Optical measuring systems measure ribbon width with tight tolerances.
3. Ultrasonic Slitting
Ultrasonic slitting are often used to produce fabric strips with closed edge, minimal material build-up. Ultrasonic cutting is ideal for precise and clean edge quality, and measurements are conducted using optical systems too.
4. Ultrasonic Stamping
Often used for highly precise fabric parts.
Ultrasonic stamping ensures tight geometric tolerances. The edges are non-fraying. One tool is used for punching and can be used for larger quantities. Optical measuring systems measure dimensions and tolerances.
5. Tubes and Tube Cuts
Different processes are used for tube production.
Ultrasonically welded overlap seams are used for functional seams, while hot cutting technology economically produces transport seams.
6. Ultrasonic Welding
Ultrasonic welding has accurate, clean welds without introducing secondary materials. SHARE produces precision blood filters by ultrasonic welded tubes.
7. Pleating
We increase the filter surface through pleating. Fabrics are firstly welded then pleated together, and cut to size of pleats.
8. Injection Molding
Share molded filters provide high flow rates and low pressure drops by maximal open area.
SHARE convert our fabrics to various plastic molded filters for medical and helthcare applications by technologies of plastic insert molding and overmolding.
By vertical integration of our global supply chain and expertise, our extensive manufacturing and production facilities, our experiences of filtration team, as well as our materials management, we take end-to-end control of all the steps in the manufacturing process, including weaving, fabrication, molding. Our ability to efficiently manufacture products not only ensures repeatable product quality, but also maintains a steady supply chain, reduces production costs and shortens lead times for our customers.
Whether you want to improve the quality or reduce the cost of your existing filter component, plan a new filtration application, or need assistance with specifications and design validation, SHARE is here for you. Our specialist problem solving skills are ready to address any challenges you encounter.
We aim to offer the most reliable and cost effective filter solutions for all filtration applications. SHARE application speciallists with decades of years experiences will help you select the best filter solution for your application.
Contact SHARE today for additional information and how we can help you with your specific filtration requirements.

9. Can plastic molded filter specifications be customized?
Absolutely, at SHARE, the materials, dimensions, shape, construction method, mesh size, and applications of the filters are all fully customizable to meet your specific requirements.
10. Regarding custom-made filter orders, do you need drawings for production?
If you have drawing (2D, 3D both available. 2D like PDF, CAD, JPG etc. 3D like STP, IGS, STL, SAT, PRT, IPT etc.) it'll be helpful for us to proceed with the production.
However, if you don't have any drawing, don't worry. SHARE can work with you to create a drawing based on a description or image of the filters you have in mind. We can get started without any drawings initially.
11. What are the common weaving types for plastic molded filters?
The most common weaving type is plain weave mesh, but we also utilize other options like twill weave mesh. Plain weave mesh is popular and affordable.
12. What situations can be anticipated in which plastic molded filters should be selected?
Plastic molding is better for mounting in the case of sandwiching. This is because it can be made without gaps in the shape of the mounting partner.
