The development of gel pens in China.

The development of gel pens in China.

As far as China is concerned, in the mid-1990s, an enterprise in Wenzhou began to mass produce gel pens. At that time, the quality was unstable due to the process being not very mature and other reasons, so it failed to form a domestic market. After that, Ningbo Beifa Company used imported ink and floating plug grease imported from the pen tip. After that, changlong love le Meicheng Road Platinum Baineng Morning light and other powerful pens: enterprises have begun to produce gel pens. Its nib ink also relies on imports at present. The output of China's gel pen has reached 10 More than 700 million of them are exported. Gel pens and water-based pens account for more than 35% of the ballpoint pen production. According to the market development trend, it seems that in recent years the output of the gel pen will continue to climb and according to the information from the pen making association: in order to strengthen the quality management of the neutral pen in Our country, to ensure the quality of the product, according to the requirements of the manufacturers and consumers of the product, by the national pen making standardization center, in 2001 Formed by Ningbo in October Mr Group co., LTD. Wenzhou hobby hunan co., LTD Qingdao rectify stationery co., LTD. Ningbo into road style daily crystal manufacturing co., LTD Shanghai forword round bead pen co., LTD Shanghai beauty co., LTD Shanghai seven companies such as China and South Korea the morning stationery manufacturing co., LTD., established the gel pen standard The drafting team, after more than half a year of efforts, China's neutral pen standard has been approved at the end of April 2002, and reported to the Light Industry Federation and the State Bureau of Quality and Technical Supervision for approval in May, so far, China's neutral pen industry has laid a good foundation, further development has become an inevitable trend.

How are gel pens classified? Neutral ink water quality index requirements.

How is the gel pen classified? Carefully observe the tips of this kind of gel pen according to the type 1 bullet tip, we will find that they are just like a bullet. In the manufacturing process, we cut a raw rod into a complete pen tip through metal cutting.​ Usually, we call this type of tip a full tip. The key difference from the bullet tip is that it is made in a non-machined way. Before it is machined into the tip, it is a complete, thin tube. Through the precision instrument from 3 directions in the front end of the thin tube to play 3 concave points, the formation of the ball bowl; And the thin tube is formed three Angle of ink tank after tank outflow, again through the ball ball rolling out of ink, completing the process of writing Needle type is suitable for manufacturing a finer written, for example, 0.30 0.25, and so on 3 needles and syringes is somewhere between with bullet and needles, appearance is more beautiful Written tip can be as thin as a needle , while the tip of the pen is the same size as the tip of the bullet. The half-needle type can make a relatively thin tip, such as 0.48, 0.35, etc. 2 According to the ink color 1 basic color neutral pen most commonly used ink color, is red, blue and black 3 kinds of 2 special color neutral pen solid, our daily use of water chalk, color ink oil belong to the category of neutral pen, these gel pens, suitable for painting card decoration and other occasions, Let our writing become more creative and more wonderful.

Gel pen material

Now gel pen holder generally used AS plastic or TPR AS plastic characteristics than polystyrene has higher impact strength and excellent heat resistance, oil resistance, chemical resistance, such AS it can be very good resistance to some polystyrene stress cracking hydrocarbons and elastic modulus is one of the higher existing thermoplastics AS for styrene - propylene eyeball copolymer, not easy to produce internal stress cracking transparency is very high, its softening temperature and impact strength than PS high physical and chemical properties SAN (AS) has a strong ability to withstand load resistance chemical reaction resistance thermal deformation characteristics and several stability SAN(AS) adding glass fiber additives can increase the strength and thermal deformation resistance, reduce the coefficient of thermal expansion SAN(AS) vikas softening temperature is about 110 C load flexural deformation temperature is about 100 C SAN(AS) shrinkage rate is about 0.3-0.7% SAN(AS) is a hard and transparent Styrene makes SAN(AS) hard, transparent and easy to process; ​acrylonitrile ingredients make SAN(AS) with chemical stability and thermal stability injection molding process. The AS processing temperature is generally in 200-250 C is appropriate. The material is easy to absorb moisture, before processing to dry more than hours, its liquidity is slightly worse than PS - point, so the injection pressure is slightly higher if stored improperly, SAN(AS) Some hygroscopic characteristics suggest drying conditions of 80 "; 2-4 hours melting temperature 200-270 C. If I thick-walled products are added, you can use the melting temperature below the lower limit mold temperature 40-80 C for enhanced materials, the mold temperature should not exceed 60 C cooling system must be well designed, because the mold temperature will directly affect the appearance of the product shrinkage and bending Injection pressure 350-1300 bar Injection speed recommended high speed injection runner and sprue all conventional sprue can be used the sprue size must be appropriate to avoid lines, spots and gaps.

Notes for purchasing ballpoint pens and gel pens.

In daily life, ball-point pen and gel pen, as everyone's necessities would be around to, so a ball-point pen and gel pen contact our life is very tight When the choose and buy, we must to ball-point pen and gel pen has a comprehensive understanding, choose - for your own ball-point pen and gel pen, so you can buy happy, rest assured Here are some ball-point pen and gel pen of choose and buy must pay attention to matters A: ball-point pen of the standard writing Angle of gb standard of 47 degrees, inferior pen or inferior ink can write only when vertical, slightly the penholder grip inclined at a difficult to write or not to come out (to hold pen around 47 degrees, counterclockwise, rapid looped is a good way to intuition inspection ballpoint pen) Three: ball-point pen the shelf life of national standard for two years, inferior dry ink months 3: inferior ink is not only a writing fluent or not to write, but will also have to spit ink or water seepage phenomenon, often looking at sample no problem, but the money after the goods paid wrong plate, problems With a ball-point pen the same Angle to hold pen gently draw straight quickly Line, good product lines continue to be not thick or fine color depth - to: and the same holding pen Angle according to the general writing pressure slowly draw a broken line, Good product lines do not accumulate ink and water) when writing slowly, there is no ink accumulation point, not thick or fine color depth - to: and the same Angle of the pen counterclockwise, fast circle, good product feel smooth and smooth) four: many opaque ball pen core will not press GB/T4306 -92 gb) requires full ink weight, only near the tip of the ink 1-2 cm; Some transparent refill ink near the tip of 1 centimeter or so can be written in ink, its residual can write 5: inferior neutral pen in addition to the problem of ink, and ball pen bead use inferior material cavity of the pipe rough Tail oil plug do not follow the tip of the elastic sealing wax ball and sealing is not good, and so on, these will be in the store after a long time or transport Or problems in the process of use six: ball-point pen and neutral pen pen stem made of plastic, inferior products fixed pen core cap is easy to slip teeth pen buckle and pen cover does not contact bayonet without glue bonding, by the tension of the plastic itself contact, easy to fall off; ​tail plug forced writing is also easy to take off the production line of these factories. Almost all pay by piece. Even if there is a quality system that will not do the process and the end of the process of inspection, the quality system is virtually empty seven: poor ink can not be used in 0-40 degrees of national standard environmental temperature range, hot weather will melt ink and you can't write when it's cold.

Did you know these about gel pen?

We believe that a lot of people when the choose and buy of gel pen is careless, actually gel pen there are many details we need to pay attention to, want to buy a high quality of gel pen also need to know to under these content 1 ink Due to the gel pen ink current technology is not mature, if storage processing transportation process problems, prone to all kinds of problems So please be careful to use a variety of ways to try to write in addition can be judged by other factors such as ink bubbles, if a lot of very obvious, that the wide family does not have a good control of the other can put a refill and in - up, ink height has 5-10mm deviation is reasonable, if more than, advise you or do not buy 2 tubing Profiteers always put the tubing diameter is very fine so that the ink seems to be a lot of some profiteers simply feel that consumers will not pay attention to the filling amount is very little special attention can choose high credibility of the brand, so that you will not buy inferior camouflage 3 rubber ball sealing nib rubber ball, we can not look down on this little thing Complaints or leak ink dry ink can want to accompany you to check - if they really can ensure depth direction under seal Four preserved the flexibility of rubber ball is close friends certainly ball bounce neutral pen has preserved, please pay attention to is easy to fall off 5 tail oil There are made from minerals, from oil refining From oil refining are generally transparent colorless, generally less impurity In addition, it can be judged by writing whether the tail plug oil can be followed well, which is very important. 6 Nib nib diameter Asian people like balls with diameters of 0.5mm or smaller. European and American people like large diameter ball material. At present, the comprehensive performance of stainless steel ceramics with tungsten carbide is better than that of tungsten carbide ball seat material with nickel white copper stainless steel brass from the comprehensive performance is better than that of stainless steel because brass is easy to rust nickel white copper nickel in many manufacturers at present, so special attention is needed.
