Product catalog summary
Introduction to FIBROFLEX® Forming Elastomers
FIBROFLEX® forming elastomers are an economical alternative to conventional dies in press shops, particularly for small batch production. They are used in forming and cutting tools, providing solutions for bending operations and forming coated or surface-finished sheet metal.

Material Properties and Advantages
FIBROFLEX® is a polyurethane elastomer known for its durability, high rupture resistance, inertness to lubricants, excellent elasticity, and thermal resilience. It is available in various profiles and Shore A hardness levels, making it versatile for different applications.

Technical Specifications
FIBROFLEX® is available in three Shore A hardness levels: 80 (green), 90 (yellow), and 95 (red). It can withstand temperatures from -40°C to +70°C and shows excellent resistance to mechanical stresses, lubricants, and thermal shock. It also resists water, oil, chemicals, and solvents.

Machining Guidelines
FIBROFLEX® can be machined using ordinary tools with a sharp cutting edge. Specific guidelines for sawing, drilling, and milling are provided, including recommended cutting speeds and angles.

Product Range
The product range includes plates, square rods, U-profile rods, hollow square rods, round rods, hollow round rods, triangular rods, and hollow triangular rods, each available in different dimensions and Shore hardnesses.

Applications and Recommendations
FIBROFLEX® is suitable for blanking, forming, and embossing operations, especially in small and medium series production. It is ideal for forming pre-coated or polished sheets without causing damage.

Conclusion
FIBROFLEX® forming elastomers offer significant advantages over traditional rubber materials, making them indispensable in toolrooms and various engineering sectors. Detailed technical data and application examples are available in the publication "Elastomers in sheet metal forming and the toolroom."

Introduction to FIBROFLEX® Elastomers
FIBROFLEX® elastomers are used in blanking, embossing, and forming processes, allowing for the cutting of sheet steel up to 2.5 mm thick with workpiece accuracy of ±0.01 mm. This method is suitable for materials like spring band steels and sheet aluminum but not for deep-drawing sheet steel.

Forming with FIBROFLEX®
During forming, the elastomer remains constant in volume and must flow into a relief gap. Hydraulic presses are preferred due to their gradual pressure build-up, reducing machine stress.

Machine Choice
Hydraulic presses are recommended for use with FIBROFLEX® matrices due to their ability to accommodate displacement and prevent overload issues common with mechanical presses.

Blanking, Forming, and Embossing Recommendations
FIBROFLEX® is suitable for small to medium series production, offering reduced tooling costs and quick adaptability to changes. It is particularly useful for pre-coated or polished sheets that must not be scratched.

Application Examples
  • Vee-Bending: Utilizes a solid punch and FIBROFLEX® pads. The bending radius affects spring-back and punch penetration.
  • Bending of V- and U-Shapes: Achieved with stacked pads or solid/hollow sections. Hollow cushions offer greater die life.
  • U-Bends with Large Radius: Require significant punch penetration and are best achieved with hollow sections or channels.

FIBROFLEX® Forming Tool Applications
  • Combined Blanking, Embossing, Punching: Allows for completion in one pass with interchangeable tool elements.
  • Bulging a Pot: Uses concave profiles to direct elastomer deformation.
  • Flaring Pipes: Requires split cheeks and conical surrounds for workpiece release.

Material and Process Limitations
The maximum permissible deformation of FIBROFLEX® cushions varies with Shore hardness, with limits set at 35% for 80 Shore A, 30% for 90 Shore A, and 25% for 95 Shore A.

FIBROFLEX® FORMING ELASTOMERS The occurrence of small batch lots in the press shop generally makes the more expensive dies of conventional design inadvisable – and it is in this sector in particular that FIBROFLEX® Forming elastomers can offer economical alternatives. The use of rubber-elastic materials, which has been practised for many years, offers new, interesting solutions for the design of forming and cutting tools, for bending over in a single operation, thanks to the constantly further developed elastomers. The advantages of FIBROFLEX® tipped tools for forming coated or surface-finished...

FIBROFLEX® - TECHNICAL DATA FIBROFLEX® - Technical data Water resistance: FIBROFLEX® can be used safely at temperatures up to +70 °C. FIBROFLEX® exhibits outstanding long-term stability under exposure to water of up to +50 °C. Swelling and/or destructive influences remain absent. This typical resistance against hydrolysis is characteristic for the specific molecular structure of the elastomer. Water/oil emulsions present no problems either. This very high resistance to hydrolysis is characteristic of the specific chemical structure of the elastomer. These are clear advantages of FIBROFLEX® over...
