Custom molded seals according to drawing, sample, or design specification
INNSEALS manufactures molded seals according to reference samples, customer drawings, or its own technical design. This results in custom sealing solutions that precisely match the installation situation, the medium, and the respective application parameters.
The molded parts can be produced from various elastomers or thermoplastics. Smallest production runs, hand samples from pilot tools, large-scale series, and elastomer-metal compounds as 2K parts are possible.

Molded seals from INNSEALS
Molded seals are used when standard seals are not sufficient in terms of design, geometry, or function. They are individually tailored to the application and can be manufactured according to a sample, drawing, or technical design.
This involves not only the shape itself, but also the material, tolerances, Shore hardness, media resistance, temperature range, manufacturing process, and quantity. INNSEALS supports you from the initial technical assessment through to the right manufacturing solution.
Hose seals
Hose seals are manufactured from compression-molded hose sections and then cut to the required height. This produces seals with compression-molded smooth inner and outer surfaces.
The process enables a sharp-edged design with tight tolerances and is particularly suitable for applications where precise geometry and clean surfaces are important.
Features
- compression-molded hose sections
- cut to height
- compression-molded smooth inner surface
- compression-molded smooth outer surface
- sharp-edged design
- tight tolerances possible
Die-cut parts
Die-cut molded seals are suitable for very small parts and precise contours. Depending on the geometry, material, and quantity, different tooling concepts can be used.
Possible tools
- steel rule die
- knife-cutting tool
- open-cutting tool
- full-cutting tool
- progressive die or progressive compound die
Possible materials
- Gummi-Elastomere
- high-pressure materials
- rubber cork
- foams
- graphite
- plastics
- beaded metal
- diaphragm materials
- paper and fiber materials
LSR molded parts made from Liquid Silicone Rubber
LSR stands for Liquid Silicone Rubber. This process is particularly suitable for molded parts with excellent surface quality and high repeatability.
One advantage of LSR molded parts is that no post-processing is usually required. Due to the higher tooling investment, the process is economically attractive primarily for larger quantities.
Advantages and notes
- excellent surface quality
- no post-processing required
- high reproducibility
- economical primarily for larger quantities
- higher tooling investment
Diaphragms
Diaphragms are primarily used in dosing, regulating, and control devices. Depending on the application, a standard diaphragm with a suitable bead, a rolling diaphragm, or a fabric-reinforced diaphragm may be appropriate.
Precise technical coordination is important for selection. Restoring forces, stroke height, damping effect, pressure differentials, avoidance of sharp edges, and other factors influence the subsequent function.
Important design considerations
- standard diaphragm with bead
- rolling diaphragm
- fabric-reinforced diaphragm
- restoring forces
- stroke height
- damping effect
- pressure differentials
- avoidance of sharp edges
- technical coordination according to the application
Waterjet and laser-cut parts
Waterjet and laser-cut parts are manufactured from sheet material and are suitable for custom contours and cut-outs. Depending on the application, the parts can also be equipped with self-adhesive film.
This manufacturing method is particularly suitable when flexible geometries, fast implementation, or special material cut-outs are required.
PA seals, FEP parts, and PTFE seals
In addition to conventional elastomer molded parts, INNSEALS also supplies technical sealing solutions made from PA, FEP, and PTFE. These materials are used when special requirements regarding pressure load, chemical resistance, or function apply.
PA seals
PA seals made from polyacrylate are used at high ambient pressures and perform similar functions to back-up rings.
FEP parts
In FEP parts, an FEP jacket protects the seal core from chemical influences. Depending on the application, the core can be made from FPM or VMQ.
PTFE seals
PTFE parts include O-rings, back-up rings in various designs, and molded parts manufactured according to drawings.
Molded parts according to drawings
Molded parts manufactured according to drawings are an important part of the INNSEALS product portfolio. Together with customers, molded seals are developed and produced to precisely match the respective application.
In addition to the geometry, material selection, media resistance, temperature range, manufacturing tolerances, and the subsequent installation situation are particularly critical.
Key requirements
- Manufacturing according to customer drawings
- Manufacturing according to reference samples
- custom design according to the installation situation
- support with material selection
- implementation of critical special tolerances
- smallest production runs and large-scale series possible
- hand samples and pilot tools for testing
