Pencil Appearance
Divided into the pencil cap and pencil rod two parts: the pencil cap appearance decorative material is mainly for the polycool material, the production process can be divided into mould making, offset printing, assembly and other processes will be completed. Pencil rod decorative materials mainly nitro fiber pencil paint, printing ink, electrified aluminium foil, rubber head and aluminium hoops and so on. The production process can be divided into pencil board, lead core, pencil rod, finished decoration and other processes
Pencil board processing will be logs open, cut off, square sawing into wood blocks, after hydrothermal treatment through the board cutting machine cut into pencil board. The length of the board is 84mm, the width is 73mm, the thickness is 4,8~5,2m, and then it is dried by heating (60~120) and denatured by high temperature (130~200), so that the pencil board reaches the degree of softening and easy to be rolled and chipped.
Lead core processing graphite lead core is graphite and clay according to a certain proportion of good, through the kneading machine, three-roller machine mixing, through the core press machine extrusion of a certain specification size (such as HB ~ 3H lead core diameter of 1, 80 ~ 2, 10mm) of the lead core, after heating (50 ~ 15) drying and high temperature (800 ~ 1100 ° C) roasting, so that it has a certain mechanical strength and hardness, and finally made of oil impregnation treatment. . Colour lead core processing and graphite lead core is similar, but without sintering. There are two processing methods: one is the clay, talcum powder, adhesive, colour, grease and wax, etc., after mixing evenly, after shaping, drying and made, known as the mixing method; the other is the ceramic clay, talcum powder, colour, and adhesive, etc., after mixing evenly extruded into the lead core or the dried lead core in the oil core containers at a certain temperature so that it can be fully absorbed by the grease made of oil immersion, known as oil immersion method.
Pencil rods are processed with a grooving machine to plane the pencil board into a grooved board with a thickness of 4,1~4,2mm and core grooves compatible with the diameter of the lead core, and then the lead core and the pencil board are glued together using a gluing agent, and then heated up (50~120) and dried for 1~8 hours under the clamping condition, and then made into white-stemmed pencils with lengths ranging from 178~180mm by the creation of the rod processing machine.
Appearance decorative processing of white pencils will be painted and printed decoration, as well as cut light, printing trademarks, rubber head, cap and other processing, so that it becomes a finished pencil with certain specifications, appearance of colour and pattern.
Committed to the production of good stationery, so that the world's children are using good quality stationery, so that good stationery to accompany the growth of children!
