Method of making a resin mould

본 발명은 수지금형을 제작하는 방법에 대한 것이다. The present invention relates to a method of manufacturing a water repellent mold. 즉 본 발명은 수지 주입구가 천공되고, 일정 두께로 경화시킨 백킹용 수지의 상부로 격자형의 브릿지를 고정장착시켜 금형 다이를 형성토록 하는 공정과, 시트왁스를 접착시킨 모크 업의 상단 바깥측으로 회형틀을 간이로 고정토록 하는 공정과, 상기 외형틀 상부로 상기의 금형 다이를 얹어 고정시키고, 상기 금형다이의 수지 주입구로 공압에 의해서 스킨수지를 주입토록 하는 공정과, 주입시킨 스킨수지가 일정시간 경화된 뒤 외형틀을 제거하고, 모크 업에서 스킨수지가 일체로 된 금형다이를 분리하여 탈형토록 하는 공정과, 스킨수지에서 시트왁스를 제거한 표면을 면삭 가공하는 공정으로 금형이 제작될 수 있도록 하므로서 모크 업(20)과 금형다이(10)를 동시에 제작 간단히 이들을 조립시켜 스킨수지(14)를 주입하는 방법으로 금형을 제작할 수가 있게 되므로 작업공정을 대폭 간소화 시키게 되는 동시에 수지소모를 절감할 수가 있어 저렴한 제작비를 제공하게 되며, 특히 공압에 의한 스킨수지(14) 주입으로 기포발생을 방지시키게 되어 수지제품의 품질을 향상시킬 수가 있게 되는 것이다. That is, in the present invention, the resin inlet is drilled and fixed to the upper portion of the backing resin cured to a predetermined thickness to fix the lattice bridge to form a die die, and to rotate the sheet wax to the outside of the upper end of the mock-up. The process of fixing the mold simply, placing the mold die on the upper part of the mold, fixing the mold die, and injecting the skin resin by pneumatic pressure into the resin inlet of the mold die, and the injected skin resin for a predetermined time After curing, the mold is removed by removing the outer mold, removing the mold die with the skin resin integrated in the mock-up, and demoulding the surface, and removing the sheet wax from the skin resin. Production of the mock-up 20 and the die die 10 at the same time can be manufactured by simply assembling them and injecting the skin resin 14. This greatly simplifies the work process and at the same time reduces the resin consumption, thus providing a low production cost. In particular, the injection of the skin resin 14 by pneumatic prevents the occurrence of air bubbles, thereby improving the quality of the resin product. Will be.

Method of manufacturing printing heads for ink jet printers and a printing head manufactured by the method

ABSTRACT: A bundle of parallel glass tubes is passed through openings in parallel alignment plates which divide the bundle into a central portion in a zone between the two alignment plates and two end portions beyond this zone. Subsequently, the tubes are softened by heating and the central portion of the bundle is con-stricted. Subsequently, the central portion is embedded in a moulding compound which, when set, forms two coupling pieces for printing heads, which coupling pieces can be separated from one another along a separa-ting plane which extends parallel to the alignment plates. Thus, important parts of at least two printing heads are manufactured simultaneously.

Composition panel manufacturing procedure and apparatus uses moving substrate covered with layer of fibres and plastic powder before heating

The procedure consists of applying a continuous layer of organic and reinforcing fibres to a moving substrate, covering at least one surface of the fibre layer with a powdered organic material - thermoplastic or thermosetting particles - and heating it to a temperature sufficient to melt the powder. The layer is then compressed and cooled to make a strip of composition material that can be cut into panels or rolled up on a support. The reinforcing fibres, of glass carbon or aramide, comprise preferably 30 - 85 per cent of the layer, and can be in the form of continuous or cut fibres, or a woven, knitted or non-interwoven layer. The powdered plastic is applied in a quantity sufficient to give a preferable final thickness of 0.5 - 0.8 mm.
