Ortofon has considerable expertise in the manufacture of rubber components developed from customer specifications. Expertise that has been achieved, not only from its many years as manufacturer of Ortofon phono cartridges, but, to a large degree, also as sub-supplier and co-producer.
Receiver suspension for hearing aid production
We have learned from the market that many manufactures have a demand for a standard program of receiver suspensions, so we have developed our own design of suspensions for Knowles and Microtronic receivers. These suspensions are available for all manufacturers. The great benefit for the manufactures is no development and tooling costs.
We cover three sizes of receivers and each size is available in three materials. The Brominebutyl / Neoprene has an extremely good dampening. Other materials are available on request.
One of our special rubber compounds with high vibration dampening properties was recently used in manufacturing of the specially shaped rubber insert in the new Ortofon tonearms TA-100 and TA-210. The TA-110 and TA-210 tonearms have gone to the next level by reducing unwanted vibrations in the arm.
The production process is carried out by means of vulcanization (compression and transfer casting).
Moulds are developed and produced in close co-operation with the customer, with Ortofon providing technical support and contact with the mould suppliers.
