Strudex Unveils Cutting-Edge Rubber Injection Technology

Strudex has acquired the most advanced rubber injection machine in the country, capable of producing rubber screen panels weighing up to 14 kg. The new machine adopts a first-in-first-out rubber injection system, ensuring the consistency of product appearance and quality to the greatest extent.

Thanks to recent advancements in rubber vulcanization technology, rubber has gradually emerged as a substitute for polyurethane screen panels in some beneficiation sites. Decades ago, producing these products via rubber injection was not feasible. However, today, rubber injection technology stands out as a cost-effective solution, enabling the production of rubber screens with hole diameters as small as 0.5 mm, thereby allowing rubber to replace polyurethane in certain applications.

In addition to acquiring the new machine, Strudex has also increased its investment in rubber molds to align with the current rubber injection process. While other manufacturers typically utilize existing polyurethane molds to produce their rubber products, this practice fails to guarantee the consistency of rubber products and may even result in blind holes in the rubber sieve plate. At Strudex, we leverage our in-house design capabilities to develop unique rubber molds. Users who have utilized these rubber sieve panels have expressed high satisfaction with their performance.

Rubber screen plates constitute one of Strudex's primary business areas. As the market for these products expands, an increasing number of users are adopting rubber sieve plates. Additionally, we are planning to further expand our business into the field of rubber injection molding. Rubber offers excellent impact resistance, addressing issues such as sticking and blinding that arise when screening wet materials. Employing rubber screen plates with 40 or 60 Shore A hardness ensures the cleaning of apertures, thereby enhancing the screening efficiency of sieve machines.

Furthermore, rubber boasts an impressive service life, as demonstrated in the iron ore industry and wet-feed equipment. The service life of rubber screen plates is comparable to that of polyurethane products, with rubber offering advantages such as reduced clogging and aperture adhesion in certain operating conditions. Additionally, rubber exhibits excellent temperature resistance, capable of withstanding temperatures ranging from 80°C to 120°C. Notably, we have successfully deployed rubber products in environments as cold as -50°C in Russia.
