AFT’s sister company, SW Plastics is a premium supplier to manufacturers of HPLC equipment.

HPLC, also known as High-Performance Liquid Chromatography is a technique in analytical chemistry used to separate, identify, and quantify each component in a mixture. It relies on pumps to pass a pressurised liquid solvent containing the sample mixture through a column filled with a solid adsorbent material.

One of the problems these manufacturers face is fittings not staying tight within the equipment due to operational vibrations with the pumps which pressurise the solvents. The equipment must use PTFE due to its inert qualities when exposed to solvents and acids, and also very low friction and non-stick properties which are the fundamental cause of the problem.

Thanks to SW plastics high level of machining precision and repeatability, they are able to continually work with their customer base to develop and perfect the fits and interferences and the geometric profiles of such components to ensure the operational effectiveness is perfected. This is achievable through a combination of our expertise within plastic machining, our expertise in product development and our expertise in working to extremely tight tolerances in these materials which fundamentally don't lend themselves to such precision.

Topped off with manufacturing equipment developed specifically to the production of HPLC fittings, SW plastics is the premium real solution provider to its customer base within this niche product industry and not just another plastic machinist.

Alongside HPLC, SW Plastics also work in other critical areas of the industry including; solvent bottle caps, adapters and connectors for tubing and other various connectors and couplers. We are committed to providing the highest quality components for not only this field, but for all parts that pass through our hands.
