An apparatus for shaping plastic preforms into plastic containers is disclosed. Said apparatus comprises a conveying device on which a plurality of blowing stations are arranged. Each of said blowing stations encompasses a blow mold, within which a plastic preform can be shaped into a plastic container. The apparatus further comprises a clean chamber, within which the plastic preforms can be conveyed. According to the invention, the zone of the conveying device in which the blowing stations are arranged is located in the clean chamber, and at least one additional zone of the conveying device is located outside the clean chamber.

Provided herein are methods of forming and optimizing cured features on a surface including controlling the surface upon which the cured features are applied. Additionally, a system for forming and processing the topographical features on the membrane is also described, along with mechanical features at specific system stations. More particularly, provided herein are methods of forming and optimizing topographical features applied to a membrane surface by controlling the membrane surface and by controlling the direction and magnitude of pressure applied to the membrane (substrate), as well as initially partially curing the topographical features, followed by fully curing of the topographical features to form the membrane having topographical spacing features formed thereon.

The invention relates to a method for supplying a polymerizable mixture to at least one molding device, said method comprising the following steps: a) providing a tank containing the polymerizable mixture (box E1), b) reaching a set value of pressure (Ps) in the tank, smaller than the ambient pressure (box E2), c) continuously maintaining the pressure (P) in the tank at the set value of pressure while supplying the polymerizable mixture to the molding device (boxes E3, E4, E41, E42, E5, E51). The invention also relates to a supply device for supplying the molding device with polymerizable mixture.

The present application relates generally to tubes, such as thin walled catheter liners with small wall thicknesses (e.g., less than 1 mm), including crosslinked fluoropolymers, e.g., crosslinked poly(tetrafluoroethylene). The disclosure further provides methods of manufacturing such tubes and systems for manufacturing such tubes.
