H&T Presspart specialises in the design and manufacturer of respiratory drug delivery devices and components for the pharmaceutical market.
H&T Presspart has over 50 years’ experience in supplying metered-dose inhaler (MDI) canisters and MDI plastic actuators and new drug delivery devices including dose counting technologies and a range of dry powder inhalers. In fact 85% of inhalers in the world will contain a component manufactured by H&T Presspart, with millions of patients putting their trust in these components every day.
Metered dose inhaler (MDI) canisters
H&T Presspart is the world’s leading manufacturer of MDI canisters, and so a key partner to the world’s large pharmaceutical companies working in respiratory drug delivery. We offer a complete range of MDI ‘cans’, designing them for optimum compatibility with your chosen valves, actuators and drug formulations.
Our standard canisters are 10ml, 14ml, 17ml, 19ml and 22ml, and we can design and manufacture specialist smaller cans, sleeved cans for lower dosing, and cans to fit all valve sizes, including gasket and o-ring sealed valve
Plasma Surface Treatment Technology
H&T Presspart offers a unique plasma process – manufactured under license from Portal Medical Ltd – for treating the internal surfaces of metered-dose inhaler (MDI) canisters, which ensures the active drug content doesn’t stick to the canister wall. This solves a problem present in many other MDI cans and ensures the patient gets the correct dose.
This fluorocarbon polymerisation (FCP) plasma treatment process improves the surface energy performance of an MDI canister, which enhances drug stability in formulations where interactions with the aluminium substrate can lead to product degradation and reduced shelf life.
Other surface treatments, such as spray coating or anodising, or alternative materials like stainless steel, can be expensive, or use chemicals which are undesirable or have long-term supply issues. The new plasma treatment improves on all these issues.
Metered-dose inhaler (MDI) actuators
H&T Presspart is the world’s leading supplier of actuators for MDIs, producing a wide range of injection-moulded plastic actuator components for the pharmaceutical sector. We create actuators for all standard pharmaceutical valve sizes, and can also customise designs to meet your needs.
PowdAir Plus Dry Powder Inhaler
PowdAir Plus is a patented capsule-based dry powder inhaler, ideal for developing markets because of its advanced simplicity, ease of use and affordability.
Most other DPIs incorporate multiple components and complex mechanics. In contrast, PowdAir Plus is a complete unit with no metal or separate parts. Neat and compact, its novel all-plastic, four-component design minimises manufacturing assembly and production costs, while improving the device’s resilience to frequent use.
Inhalation Product Technology Centre (IPTC)
H&T Presspart Manufacturing, have further expanded our research and development capabilities with the introduction of an Inhalation Product Technology Centre (IPTC) which will help support the strategic projects of H&T Presspart and most importantly our customers.
Our IPTC will deliver the capabilities to support new product developments and strategic initiatives with our customers. H&T Presspart has an in-depth technical understanding of the products we manufacture and assembly and IPTC will enhance those capabilities and deliver a customer focused device development and drug related performance understanding.
