Custom rubber molded parts, designed and developed cost-effectively.

In most cases, rubber molded parts are no standard elements. Vibraplast AG is a development partner in molded rubber articles, tailor-made, in optimal geometry and material quality. We combine our skills with the know-how on suspension, kinematics, and acoustics as well as the many years of professional experience in the production of rubber products. We are always happy to help you find the right rubber quality for your requirements so that the elasticity is maintained during the entire service life; It should largely remain unaffected by environmental influences such as heat and cold, light, ozone, or contact media. Our design department is tasked with taking into account all the details of the conditions of use and the different types of stress that the rubber parts to be produced will be subjected to. For the production, we use vulcanization presses or injection presses that are perfectly suited for single, series, or mass production. Available range of rubber qualities: NR natural rubber, SBR styrene-butadiene rubber, NBR nitrile rubber, CR chloroprene rubber, EPDM ethylene propylene diene rubber, IIR butyl propylene diene, VMQ silicone propylene diene We are also happy to consult with you and work out the optimal solution for your requirements. Feel free to call us or send us an e-mail if you have any questions!

Frequently asked questions (FAQ)

Hardness testing of elastomers (rubber) The hardness test of elastomers (rubber) which is most commonly used is the Shore hardness test according to DIN ISO 7619-1. The Shore hardness is the resistance of a rubber sample to the penetration of a conical body of certain dimensions under a defined compressive force. Depending on the design of the measuring body, a distinction is made between Shore A for softer elastomer compounds and Shore D for harder elastomer compounds. For a perfect measurement of Shore hardness, the standard specifies a sample thickness of 6.0 mm. If measurements are carried out on finished products with smaller wall thicknesses, they usually lead to incorrect results. Commercially available elastomer compounds for technical rubber mouldings have a hardness range of 20-90 Shore A

Different types of adhesive can be used for bonding rubber. The choice of the right adhesive for rubber depends on the mixture of the respective rubber, therefore it is advisable to test it on a small area before gluing the rubber over the entire surface. In our online shop page https://www.vibraplast.ch/de/gummi-kunststofftechnik/Klebstoffe you will find a range of superglues for gluing rubber to each other or for bonding with different material combinations. The following elastomers/rubbers have proven to be suitable for bonding with superglue: EPDM (ethylene-propylene-diene rubber) NR (natural rubber) CR (Cloroprene rubber neoprene) IIR (isobutylene-isoprene rubber) SBR (styrene-butadiene rubber) NBR (nitrile butadiene rubber) Rubber bondings with superglue have the advantage that it hardens in a few seconds and the adhesive bond can be loaded immediately. The following advice for bonding rubber should be observed: clean surface no double-sided adhesive application a glueing gap as thin as possible in the case of mitre-cut gluing or butt gluing, ensure a straight, smooth and fresh cut skin contact should be avoided if possible, wear latex gloves if possible

Neoprene is a brand of the DuPont company and is a CR chloroprene synthetic rubber. The abbreviation of chloroprene rubber is CR. Vibraplast AG has no CR neoprene in its product range but a comparable commercial CR rubber with similar quality characteristics. Consult our technical data sheet in our online shop and compare the properties of our CR rubber quality.

The FDA (Food and Drug Administration), is an American supervisory authority, which is responsible for the control of all goods placed on the market in the USA. This includes all imports into the USA, therefore the regulations of the FDA authority are also important for European manufacturers. These regulations are binding for exporters to the USA. The FDA sets extremely strict requirements in the food sector where a large number of rubber and plastic products are used and as a result come into contact with food or drinking water. The materials must not release any ingredients into the food. As a result, all plastics that come into contact with food should be FDA-compliant.

Food grade rubber/elastomer is safe to use with food and meets the requirements of the FDA, Food Standards Agency. Food grade elastomer is non-toxic and does not discolor or alter the food with which it comes into contact. Food grade rubber qualities can be used safely in the production of food and beverages.
