Medical Device Manufacturing This makes injection moulding for small batches economical

Editor: Alexander Stark

In medical, diagnostic and analytical devices, in industrial automation as well as in development processes, precise plastic parts are needed in small series. Injection moulding is usually out of the question due to the high tooling costs. With a new technology from Bürkert, this manufacturing process is now economical from as little as 250 units produced.

The quality of the material and the flushability of the channels have high priority in analytical equipment for in-vitro diagnostics, but also in other procedures in which gases or liquids are precisely distributed; after all, the accuracy of the systems depends on this. At the same time, however, economical solutions are also required. Especially with small series, it is a challenge to keep production costs low. Bürkert Fluid Control Systems in the Criesbach system house proves that quality and economy are not mutually exclusive with a standardised, modular plastic injection moulding technology that is suitable for small series with quantities between approx. 250 and 2,500 units. Despite the standardisation, individual adaptations are possible. Since everything from consulting and planning to material selection and qualification, component development, prototyping and simulation to mould design including pilot plant and production in the company's own plastic injection moulding shop is in one hand and the customer has only one contact person, time-to-market can be reduced considerably.

Individual small batch production through adapted injection moulding process

Normally, high tool costs for the injection moulds make the process unattractive for small series. Based on over 40 years of experience in plastic injection moulding, Bürkert has therefore developed a modular tooling system where only aluminium inserts and not the complete steel base frame have to be custom-made. This lowers the investment costs and reduces the project time without compromising quality. Due to the high vertical range of manufacture, the entire process up to the series product takes place under one roof and the components are perfectly coordinated. Special solutions can also be taken into account and, for example, supplied housing parts can be integrated.
