The demands of manufacturing pharmaceutical springs

The pharmaceutical industry is a particular demanding one with the need for the highest standards of manufacture. That is why RHD operates a sophisticated pharmaceutically-approved clean room for the manufacture of pharmaceutical springs. This facility offers exact control of humidity, temperature and even pressure to provide optimal cleaning conditions. It is also robotically cleaned in order to eliminate bacteria and dust. The computer managed production processes, meanwhile, ensure that a precise control is maintained on every production project, with real-time exact knowledge of where each stage of the project is.

The complexity of pharmaceutical springs

It is not just the production process of pharmaceutical springs that must be exact, the design, too must meet all desired criteria. This involves conducting careful consultations between the client and the technical and marketing managers in order that the RHD team fully understands the nature of the project and the required outcomes. This involves developing an agreed technical specification and also understanding budget and business needs. Decisions must be made about the grade of steel to be used, the spring’s compression characteristics and its relaxation constraints. Only once this close and full understanding of the client’s needs is achieved, does the project go ahead.

The need for partnership in the design and production of pharmaceutical springs

RHD is very proud of its customer list, which includes some of the leading players in the automobile, cosmetic and pharmaceutical industries. The company believes that this success is due in no small part to the way that it works closely with client in developing a true partnership approach. In fact, RHD does more than just design and produce pharmaceutical springs for its customers, it also develops lasting and valuable business partnerships that deliver value to these clients.

On the lenghty list of items that would be useless without one or several small springs, one would find shock absorbers, lighters, robots and industrial machines, bottles of perfume, watches. Springs are usually hidden; yet they are vital components for a very large amount of familiar objects. Because of exposure to multiple kinds of stresses and small dimension, springs production processes need to conform to very high quality standards. For leading-edge fields, among which high-tech industries, automotive, pharmaceutical, and other cutting-edge sectors,  it is of the utmost importance that the springs incorporated in their products are of the best quality.
