摘要:
An ophthalmic lens mold includes a first mold (32) half having a front side and a back side. The front side (40) defines an optical surface. A second mold half (34) has a front side (42) defining an optical surface. Upon alignment of the first mold half with respect to the second mold half so that the front sides oppose each other, a mold cavity (96) is formed between the front sides to form an ophthalmic lens therein from a moldable material. The first mold half includes a first section (40) that transmits curing light (104) and that extends from the back side to the front side. The first section includes at least an area of the first mold half optical surface enclosed by an outermost circumference (72) of the ophthalmic lens. A second section (46) is comolded with the first section and blocks the light. The second section is disposed with respect to the first section so that the second section prevents the curing light incident to the back side from passing through the first mold half into an area of the mold cavity (96) extending from the first mold half front side (40) to the second mold half front side (42) surrounding and extending radially outward of a boundary that includes the ophthalmic lens circumference (72) and so that the first section passes the incident light to an area of the mold cavity bounded by and within the boundary.

Rotatable rolls of plastic material are produced in the following manner: a thermoplastic material is injected between a roll shaft and an outer roller layer, whereby the volume of said material contracts during cooling, shrinks onto the roll shaft and shrinks away from the outer roller layer, or the outer layer is initially injected according to a multi-component injection moulding method, after which a thermoplastic material is injected between the outer roller layer and the roll shaft, whereby said material also shrinks onto the roll shaft and shrinks away from the outer roller layer. Said method produces rolls of plastic material, consisting of both an inner roller layer (2) which is firmly connected to the roll shaft (1) and an outer roller layer (3) which can rotate freely against said inner layer by means of a sliding gap.

A process and device are disclosed for manufacturing a toothbrush with a handle part and a bristle head carrying a plurality of bristle bundles. The basic body of a bristle head is formed from a hard component in an injection-moulding device and the bristle bundles are embedded at their ends in bristle bundle-holding regions joined by connecting webs. These connecting webs are cut through and the basic body of the bristle head is extrusion-coated with a soft component.

The invention concerns a throttle device, especially a butterfly valve (12) in an intake pipe of an internal combustion engine. It has a butterfly spindle (11) running concentrically to a central axis and the throttle butterfly (12) and the surrounding housing (10) have facing sealing surfaces. The sealing surfaces are fitted with at least one elastomeric seal.

A method of assembling a vehicle includes the steps of forming a plurality of different modular window assemblies each having at least one sheet of transparent material upon which a gasket has been formed. The modular assemblies include a driver's door and window assembly (30), a complementary passenger's door and window assembly (72), a windshield and leaf screen assembly (31) and a rear window assembly (42). Each of the modular window assemblies (30, 31, 42, 72) are manufactured separately and then brought to a vehicle assembly line to be installed in the vehicle body (71).

The procedure for the manufacture of strips of vials comprises the steps of: providing a forming mold (7) having a plurality of female housings (8) and as many male elements (9), wherein the female housings (8) and the male elements (9) can be coupled together to define an interspace (10) for forming a strip (1) of vials (2); - injecting under pressure a first material in the fluid state within the interspace (10); hardening the first material within the interspace (10) to obtain a strip of semi-finished vials (11); modifying the shape of the interspace (10); - injecting under pressure a second material in the fluid state within the modified interspace (10) directly in contact with the strip of semi-finished vials (11); and hardening the second material within the modified interspace (10) by making the second material adhere to the strip of semi-finished vials (11).
摘要:
Die Erfindung schlägt eine Palette (9) vor, mit einem Grundkörper (1) aus einem Kunststoffmaterial, einem Deck (2), das die Oberseite der Palette bildet, einer auf der Oberseite des Decks vorgesehenen rutschhemmenden Beschichtung (10), und Einfahröffnungen (3) zur Aufnahme der Gabel eines Flurförderfahrzeugs, wobei eine Einfahröffnung einen oberen Rand (6) aufweist, der von der Gabel unterfahrbar ist, dieser obere Rand an seiner Unterseite mit einer Anti-Rutsch-Schicht (20) versehen ist, die rutschhemmende Beschichtung und die Anti-Rutsch-Schicht aus demselben rutschhemmenden Material bestehen und durch einen mit diesem Material gefüllten Verbindungskanal (19) miteinander verbunden sind, das rutschhemmende Material aus der selben Kunststofffamilie wie der Grundkörper besteht und stoff schlüssig mit dem Deck verbunden ist, und wobei die rutschhemmende Beschichtung (10) und die Anti-Rutsch-Schicht (20) als gleichzeitig hergestellte Bereiche eines Spritzkörpers geschaffen sind, der sowohl stoffschlüssig als auch formschlüssig mit dem Grundkörper (1) verbunden ist.
摘要:
The multistep injection molding device (210) is for manufacturing thick lenses (100) for use with an illumination apparatus. The injection molding device (210) includes two sets of mold core inserts (250, 252) forming mold cavities when the injection molding device (210) is in a closed position. The lens core part (120) is formed in a first injection shot station. The molded lens core part (120) is then moved to a post-molding cooling station in which it is further cooled inside a corresponding mold cavity. Two outer lens parts (122, 124) are formed sequentially over the lens core part (120) in second and third injection shot stations. A method of manufacturing a thick lens (100) is also disclosed.
摘要:
Bei der Herstellung eines Kunststoff-Formteils, welches eine in Kunststoff eingebettete Barriereschicht aufweist, wird an einen dreidimensionalen Vorformling aus einem Zuschnitt einer Mehrschicht-Barrierefolie, welche eine beidseitig mit Kunststoff beschichtete Barriereschicht aufweist, nacheinander in unterschiedlichen Kavitäten des Spritzgießwerkzeugs Kunststoff angespritzt. Dabei wird jeweils durch die eingespritzte Kunststoffschmelze die Kunststoffbeschichtung des Barrierefolienzuschnitts zumindest oberflächlich angeschmolzen. Und der Vorformling wird auf der jeweils gegenüberliegenden Seite durch eine an dem betreffenden Teilwerkzeug ausgeführte Aufnahme unterstützt.
