More than 60 years of experience with continued improvement in quality and efficiency are the foundation for our excellent radial-elastic fastener products.
Our range includes standard ISO coiled spring pins and slotted pins and additionally a high variety of customized pins as well as compression limiters and reinforcement sleeves made of rolled band strip material.
Meeting the highest quality requirements is a matter of course for us. We are looking forward to fulfil your individual tailor-made solution.
Our broad portfolio contains the following variations:
Coiled Spring Pins
Coiled spring pins are radial, elastic fastener elements and flexible at use. Coiled spring pins are frequently used as a joiner pin for two or more components, a hinge or shear pin. Inovan produces coiled spring pins with all established surface finishings and upon request also in customized versions.
Our competent personnel and best manufacturing equipment guarantee high precision and quality. Customers benefit from efficiency in series and large-series production particularly by using multiple progressive compound tools.
Coiled spring pins are used as fastener elements for a wide range of applications in the automotive up to the packaging industry.
Our delivery program includes the dimension range from 1 x 4mm up to 16x180mm and various versions:
|ISO 8750||Standard version|
|ISO 8748||Heavy duty version|
|Super elastic||Light version with high radial elasticity and less intrados pressure (1.5 windings)|
|TURBO||With circular cross section (2 windings)|
|3 Windings||For high shear forces|
With integrated firm-/loose function or for insertion aid
With customized solutions in dimensions, materials, coatings
In addition to coiled spring pins, slotted pins are another part of our wide range of products in mechanic connection technology. Slotted pins are produced according to ISO 8752 and ISO 13337 or upon customer request. They are rolled from strip material and have a permanent slot on the longitudinal axis. Shocks and impacts can be easily absorbed by the spring behaviour.
Our products are available with all common surface treatments and are therefore an appropriate economic and technical alternative for grooved pins, cylindrical pins, rivets and bolts.
Slotted pins are used in the automotive, electronic and packaging industry for varies applications.
Our product range contains:
|ISO 8752||Heavy duty|
|ISO 13337||Light version|
|ASME B18.8 n||According to US-standard also in inch-dimension|
|JIS-B2808||According to Japanese standard|
|Automotive-version||With reduced slot size as interlocking protection|
|Closed version||As interlocking protection e.g. for surface treatment|
|Customized||With customized solutions for dimensions, materials and surface treatments|
Compression Limiters / Reinforcement Sleeves
Compression limiters /reinforcement sleeves are used as fastener elements in various industry sectors. Our products are manufactured upon customer request and available with all common surface treatments.
Compression limiters /reinforcement sleeves provide multiple benefits. They offer a cost effective alternative to turned parts and can be delivered depending on the requirement with chamfered ends, stampings and embossing's on the lateral surface. In addition, Inovan offers various special solutions:
- Longitudinal open slot for assembly after plastic moulding process on request with interlocking device
- Longitudinal slot nearly closed for plastic over moulding
- with chamfer
- Depending on the technical requirement, products with notches and embossings are deliverable
Compression limiters /reinforcement sleeves are used in the automotive and plastics industry and in precision mechanics.
