DYNAMIN, present on the market ever since 1954, boasts over 40 years
of materials experience.
We have always monitored the evolution of explosion-proof materials and searched only for "the best".
This approach has gradually helped us to improve our technical know-how and convinced us to consider cast iron superior in respect to light alloys and employ it without any regrets or exceptions, for the manufacture of housings and accessories for explosion-proof appliances.
The type of cast iron employed by DYNAMIN is UNI/ISO
185 (ex G20 UNI
5007) that has a minimum tensile strength of 196 N/mm 2 . It is subjected
to zinc electroplating surface treatment and chrome finishing in accordance
with ISO 2081 (ex UNI 4721).
The surface roughness of cast iron is particularly suitable for further surface treatment such as painting, plastic covering etc.
The most appealing qualities of cast iron are:
DYNAMIN is not the sole company which employs this type of material
in fact an increasing number of famous national and international companies
have also acknowledged the effectiveness of cast iron and have introduced
this material too.
Cast iron has helped to solve the very serious problem of corrosion, especially caused by machining chemicals and salty-corrosive environments, where light alloys are renowned to fail in time.
Unfortunately cast iron has the following drawbacks:
In spite of these drawbacks DYNAMIN is still very competitive and can
offset the higher costs by ensuring a very high quality production output.
This is possible because DYNAMIN leverages the most modern and up-to-date
high technology solutions.
Despite the choice of cast iron as main raw material, other materials such as light alloys and stainless steel are available on request.
