Darou Shisheh was established in 1981 as the first local manufacturer of Neutral High Borosilicate Type I Pharmaceutical glass containers to fulfill the pharmaceutical industry demand for ampoules.

During this time, with continuous effort, teamwork, training, and dedication, we have managed to sustain the majority shares of our local market and export Dashco products to our international customers.

Our company currently enjoys running above 50 production lines with the nominal annual production capacity of 1 Billion pieces of glass Ampoules, Vials, and Cartridges in different sizes and colors (Amber & Clear).

In 2003, we established sina glass neutral high borosilicate tube (type I) manufacturing site to localize our glass tube demand.

Today both companies (Darou Shisheh and Sina Glass) have merged into one company under Dashco name, with an annual production capacity of 5000 tons of clear and amber tubes of different diameters and thicknesses.

Our tubes have also passed the required standards and approvals for Type I borosilicate tubes, tested in well-known, accredited European laboratories.

The high-quality products manufactured with up to date state of the art high-Tech automatic production and quality control machinery together with our management & personnel commitment and manufacturing Know-How is the real Key to Our Success.

A single objective directs our efforts:

“To become our customers’ most valued Supplier”

To accomplish this, we work closely with our customers, understand and justify their needs and perform continuous improvement by developing new products and skills.
