Pencil Crafting Process

The blade and the pencil to form a 15 degree angle, and then smooth from the back before pushing the knife back, Pencil so that the force to be uniform, the direction to be stable, Pencil try to keep the 15 degree angle, do not force too much or force uneven, otherwise cut Pencil rugged, both ugly and hands!

The tip of the best to keep in about half a centimeter, Pencil too short with a while and have to cut, too long easy to break, the front of the most sharp, Pencil refills do not generally thick, from the root to the tip, from coarse to fine and change, , Do not be too fine!

Tell the child to write the time, side of the rough, you can change, side of the rough, Pencil the other side certainly fine, so that not only save the pencil, but also save the time to cut pencil!

Divided into pencil cap and pencils in two parts: pencil cap appearance of the main decorative materials for the polyester material, the production process can be divided into mold, offset, Pencil assembly and other processes to complete. Pencil poles The main decorative materials are nitrocellulose pencil paint, printing ink, foil, rubber and aluminum hoop, and so on. Production process can be divided into pencil panels, lead, Pencil pencils, finished products such as decorative process.

Pencil plate processing will open the wood, cut off, open the side saw into a wooden block, after the heat treatment by cutting machine into a pencil plate. Plate length 184mm, Pencil width 73mm, thickness 4.8 ~ 5.2mm. And then heated (60 ~ 120 ℃) dry and high temperature (130 ~ 200 ℃) denaturation treatment, Pencil so that the pencil plate to soften the degree of easy to roll.

The lead core processing graphite lead is made of graphite and clay according to a certain proportion, Pencil the kneading machine, three-roll machine after mixing, through the pressure die extrusion of a certain size (such as HB ~ 3H lead diameter of 1.80 ~ 2.10mm) lead, by heating (50 ~ 150 ℃) drying and high temperature (800 ~ 1100 ℃) roasting, it has a certain mechanical strength and hardness, and finally made by oil immersion treatment. Pencil The color lead is similar to graphite lead, but does not require sintering. There are two kinds of processing methods: one is clay, talc, adhesives, colorants, greases and waxes and other mixed evenly after forming, Pencil drying and made, known as the mixing method; the other is the clay, talc , Pigment and adhesive, etc. Pencil are mixed evenly after extrusion into lead or the dry lead core placed in the oil core container, at a certain temperature to make it fully absorb grease and made, known as oil immersion method.

The pencil bar is machined with a pencil planer and cut into a groove plate with a thickness of 4.1 to 4.2 mm and a core groove adapted to the diameter of the lead core. Then, Pencil the adhesive is used to bond the lead and the pencil sheet together. (50 ~ 120 ℃) after drying for 1 to 8 hours, Pencil the workpiece was machined into a white rod pencil with a length of 178 to 180 mm.
