We are the top supplier of tooling for market leading medical blood filter manufacturers

Several of our long standing customers over the last 40 years are leaders in the blood filtration component industry. In that time we have developed unparalleled expertise in the design and manufactured dozens of complex plastic injection moulds including a wide range of filtration components such as various types of

  • blood filters,
  • check valves or
  • inline vented leur adapters.

The components moulded by our tooling are used across almost every aspect of the medical industry such as epidural procedures, transducer protector filters, blood transfusions, syringes, intravenous drips, and others.

We’ve successfully completed dozens of moulds in this market niche, incorporating techniques such as;

  • overmoulding,
  • screenfeeds,
  • in mould punching stations

in the manufacture process.

Smithstown Light Engineering UK have significant expertise in working with a wide selection of mesh and membrane filters. Membrane filters offer microfiltration with pore sizes from 0.1 µm to 8 µm.  Membrane filters would typically be used for applications such as cell retention, particle collection, microbiological analysis.


Mould Spares / Precison Components
We offer our customers a comprehensive manufacturing solution. As well as offering full mould design and manufacture, we can also manufacture precision mould components , we can manufacture to drawings or 3d models and we can offer a reverse engineering service for your mould if necessary. Smithstown UK can provide you with a new set of drawings and high quality precision spares for your tooling. Please click on our Precision Components page to learn more of the type of work we do

Mould Maintenance & Refurbishment

For certain customers, our services are integrated into their business. We operate as an outsourced mould maintenance department providing scheduled maintenance (according to the customers schedule). This includes performing regular scheduled tasks such as dis-assembly, cleaning, checking for wear or other problems. If replacement parts are required we can reverse engineer and create a digital model of the existing components so that we are assured our replacement parts will work first time, thereby avoiding downtime for these customers.
