Rubber bellows
Rubber bellows are usually employed as protections for parts in motion (such as pneumatic or mechanical cilinders) or for still parts. The applications of rubber bellows are countless.
Rubber molding
EXSTO Italia has more than 60-year experience in the production of molded rubber products
As well as supplying the finished product, we are also able to supply the moulds, manufactured by the most reliable Italian mould-makers, plus 2D and 3D design and engineering support.
Commonly EXSTO works with the following compounds, although other polymers can be developed for special requests, such as compounds in compliance of FIAT and DBL norms:
FKM, EPDM, NBR, NR, SBR, HNBR, Silicone, Neoprene, Epichloridrine, Vamac, Fluorosilicone, Polyurethanes.
Vamac compounds are fire-resistant, non-conductor, and low class in fumes emission (class 0).
EXSTO Italia employs the most popular rubber molding techniques, such as compression moulding, capillary injection molding, injection-compression molding and its presses are equipped with vacuum systems.
We built an A/C facility where we stock rubber compounds in a controlled environment: the rubber compounds we outsource are 100% tested before use according to several parameters like the hardness, elongation, tear, rheometric curve, …
We can also provide certificates of compliance with RoHs and REACH norms of our rubber compounds, or to different norms if required.
