Bellows, for example, a roll bellows and a folding bellows, can be produced that can be used at higher temperatures such as those prevailing in modern articulated constructions, using a mixture comprising at least one thermoplastic elastomer selected from the group of copolysters with a hard segment and a soft segment, wherein in a first step the at least one thermoplastic elastomer is mixed with approximately 0.8 wt. % to approximately 5 wt. % triallyl isocyanurate, based on the total amount of the mixture; in a second step the bellows is produced; and in a third step, the bellows is exposed to an ionizing irradiation in a range from approximately 140 kGy to approximately 350 kGy.

A micro moulding machine and process for forming small plastic parts for the medical device industry. The machine adds heat in two steps to a precision sized plastic pellet and then displaces the entire pellet volume into the mould cavity. A substantial amount of heat is added to the pellet by forcing it through an orifice very near the gate of the mould. The pneumatic pressure to drive the pellet through the orifice is controlled to regulate the amount of heat introduced into the pellet.

Resin supply system in which resin material is stored in a pouch in a degassed state ready for use. The pouch comprises a body portion forming a reservoir for resin material and a connector portion in fluid communication therewith. The connector portion includes an outlet which is configured to be connected to an injector head of an injector assembly, the injector head being connectable to a mould by means of connecting tubing to provide a resin supply thereto. The pouch is configured to be mountable in a housing of the injector assembly and is compressed by hydrostatic pressure of water surrounding the pouch in a chamber of the housing. The application of pressure by a piston moving in a direction transfers pressure to the water and then to the pouch in a controlled manner to provide the resin supply to the mould. After use, the pouch is removed and discarded thereby substantially eliminating the need for cleaning of the housing after use.

According to one embodiment, a mold includes a substrate clamping surface, a cavity, a suction part, a vent, an intermediate cavity, and an opening/closing part. The substrate clamping surface contacts a surface of a processing substrate. The cavity is recessed from the substrate clamping surface. The suction part is recessed from the substrate clamping surface. The vent is provided on a path between the cavity and the suction part, communicates with the cavity, is recessed from the substrate clamping surface to a vent depth. The intermediate cavity is provided between the vent and the suction part on the path, communicates with the vent, and is recessed from the substrate clamping surface to an intermediate cavity depth deeper than the vent depth. The opening/closing part opens and closes the path and is provided between the intermediate cavity and the suction part on the path.

A molding system for molding electronic components mounted on first and second sides of a substrate has a molding cavity onto which the substrate is locatable for molding. The molding cavity has a first section covering a molding portion of the first side of the substrate, and a second section covering a molding portion of the second side of the substrate. First and second pots have plungers for compressing molding compound placed therein. First and second runners connect the first and second pots to the first and second sections of the molding cavity for introducing the molding compound onto both sides of the substrate. In particular, the runners extend at least from an edge of the substrate along both sides of the substrate to the molding cavity.
