To Mr. Takahashi, a major pharmaceutical manufacturer
The quality of pharmaceuticals is extremely important. At our company, we have been using stainless steel for our main manufacturing equipment for quite some time. Stainless steel is stable with many pharmaceuticals and is very resistant to rusting and degradation.
On the other hand, in order to meet the increasingly high demand for pharmaceutical quality in recent years, we have been using stainless steel for peripheral equipment such as storage containers and transportation tools in addition to our main equipment. For example, when storing raw materials, we have been switching to stainless steel containers as much as possible because there is a risk of cut or abrasion materials mixing into the product when stored in plastic bags or containers. Specifically, when storing raw materials for oral drugs, we use Nitto Kinzoku Kogyo’s SMA-CTL buff polished containers for most of them. For higher quality injectable and oral drug products, we use SMA-CTL electrolytic polished or milk can type electrolytic polished containers.
Changing the subject, often overlooked specifications of stainless steel containers are the curled and handled parts around the mouth. Normally, these parts have many small gaps and are difficult to clean, making dirt easy to accumulate. In this regard, Nitto Kinzoku Kogyo can weld curls and make handles with round bars, which is very helpful in making specifications suitable for pharmaceutical manufacturing.
Furthermore, buff-polished containers can be used without problems if they are cleaned sufficiently, but we choose electrolytic polished containers because we do not know whether buff stains can be completely removed, especially for injectable purposes, and many electrolytic polished products from other manufacturers did not meet our requirements. Nitto Kinzoku Kogyo has studied this well and provides us with very high-quality electrolytic polished products.
Through solving each of our requests, we now have reached the point where we can ask for the grade of products we want by telling Nitto Kinzoku Kogyo our intended use. We believe this is very important. Many pharmaceutical manufacturers who use Nitto Kinzoku Kogyo’s stainless steel containers provide useful information, and we trust the brand because they also conduct their own research. To me, when it comes to stainless steel containers, I immediately think of Nitto Kinzoku Kogyo’s containers.
