摘要:
An embodiment is disposed of a method of making gloves, more particularly polyvinyl chloride (PVC) coated gloves. The method comprises providing a liner, and coating at least a part of the liner with a PVC paste to form a coating having an outer layer, applying particles of a soluble solid to the outer layer of the coating and curing the outer layer. Preferably, the method further comprises gelling the outer layer after applying the particles and contacting the gelled outer layer with a solvent before curing. Preferable, the soluble solid comprises a solid acid.

Process and apparatus (10) for forming plastics by heating an open mold (12) and contacting the open mold (12) with plastic particulate material (16) held within a container (14) to form a melted skin on the mold (12), and resulting articles made therefro. The mold (12) is provided with a carrier (18), which may include heating and cooling lines for achieving a desired mold temperature. Single skin molded articles may be multi-layered with or without paint on the surface. Multiple skin moled articles may include sandwiched layers of plastic filler or expandable foam filled centers, with or without various inserts or reinforcements.

摘要:
A medical device such as a catheter, stent or balloon, is formed by depositing a radiation curable composition on a form (30) made of ice or wax. The deposited composition may be cured by irradiation, suitably with UV light. Complex structures can be built up if the deposition or curing is achieved imagewise. Compositions which photocure to polyester, polyamide or polyimide may be employed. A particular structure is a balloon for a rapid exchange catheter which has a guide wire lumen (85) passing through the balloon cone walls (86, 87).

Verfahren zur Herstellung eines komplizierten Bauteils aus Metall, Keramik oder Kunststoff, wobei Pulver (7) mittels Transportgas in eine unter vermindertem Druck stehende, sich in einem Behälter (11) befindliche, gasdurchlässige Negativform (14) eingeblasen und vorverfertigt wird, worauf die Negativform (14) aus dem Behälter (11) herausgenommen und der Grünling entweder in einer separaten keramischen Stützmasse oder in der aus Keramik bestehenden Negativform (14) selbst gesintert wird. Varianten zur Herstellung eines Hohlkörpers oder eines geschichteten Körpers als Bauteil durch Programmierung des Pulver-Einschiessens.
摘要:
This invention intends to make it possible to form a surface-hardened continuous layer evenly and to a specified thickness on a part or the whole of the surface of the foamed synthetic resin product during the internal foam molding process without greatly changing the ordinary foam molding process. A synthetic resin granular material having foaming nature is brought into contact with a heated part of the product surface so as to be melted and a molten resin layer is formed on that portion of the surface of the molded product corresponding to that portion of the surface of the metallic mold for internal foaming molding heated to a temperature higher than the melting point of said resin material, and then said molten resin layer is hardened to compose a foamed synthetic resin molded product having a continuous surface-hardened layer formed during the process of internal foam molding.
