Outdoor playground plastic raw materials

The main runway of plastic raw materials plastic track polyurethane plastic heritage is internationally recognized as the best sports Aile amusement park pavement, which originated from the United States in 1961, he first breakthrough technology related material with polyurethane rubber laid the first 200 meters of Horse Racing Heritage, in Aile swing sets began laying track and field legacy, now worry as part of modern sports facilities. Plastic heritage can be divided according to the structure: prefabricated, hybrid, complex peace particles, breathable and so several colors: red and green iron-based. Other colors can also be made according to customer needs. Thickness: 13 mm (National Standards) specifications and size (to 400 m runway as they): Heritage usually 6-8 of road, road width 1.22m-1.25m, the entire runway area at about 6900 m2 (including runways, fairways, jump shot, semi-circular area, etc.).

Characteristics of plastic tennis courts

Hard court surface layer using acrylic (hard acrylic / elastomeric acrylic) paint, the popular Hard tennis (U.S. Open, Australian Open, French Open) Aile exercise machine uses acrylic paint. Such coatings can be used in asphalt or concrete substrate. Depending on the hardness and the ball can be divided into two series of hard and elastic. Hard series is mainly constructed as follows: an adhesive layer, texture layer, the surface layer and the paint color line. The series is between the elastic adhesive layer and add texture layer thick, thin rubber layers each layer.

Plastic moulds, rounding

1. Start with spring section: generally speaking, there are square and merry go round, round me, because how long how long it would take that kind of cut. Grade 3 or 4 grade boss know best how to save cost, today to talk about design benchmark is not suitable for.
2. The spring to first understand the basic specifications: freedom, long long compaction, load and maximum compression spring rate. (this is for mould design, agencies have other considerations, but also very much the same).
3. Red, blue and yellow various load difference, no longer say more look-up table, please. I want to say is the spring compression ratio, the characteristics of the spring is as long as the actuator stroke more than elastic limit, the life is a sharp decline, speak only blue, his spring compression rate of 40%, if the design of the spring compression ratio less than 40% (35% give a safety factor), hang up soon.
4. Everyone at the top of the design of the plate spring have considering to stop travel restrictions, have given to a modest increase in the thickness of the template, you consider how much to the top plate spring from the parting surface, strength and bite (ENGAGE) how long the appropriate return pin.
For the above mentioned some good is almost the actual experience, for a beginner is a bit "zhang two Jin Gangmo is not the end", and mold the fitness really city more read more contact with the site, so the accumulation of experience can truly become a master, because... Mould is very and love and hate and afraid of being hurt, really hit no predecessors or friends to help, just want to commit suicide, below is my personal experience in the design process, feel good can be for reference, please comment: when bad

Basic knowledge of the plastic moulds

1, the introduction
That we use in our daily life and production to the various tools and products, to the base of the machine tool, the fuselage shell, small to a germ head screws, buttons, and all kinds of household appliances shell, which has close relation with the mould. The shape of the die decides the shape of the products, precision mold processing quality and determines the quality of these products. Because the material of all kinds of products, appearance, specifications, and different purposes of mould into casting die, forging die, die-casting mould, stamping mould of plastic moulds, such as, and plastic toys moulds.
In recent years, with the rapid development of plastic industry and general engineering plastics in the aspects of improving strength and precision, the application range of the plastic products are also constantly expanding, such as household appliances, instrumentation, construction equipment, automotive industry, daily hardware, and many other fields, proportion of plastics is rapidly increasing. A reasonable design of plastic parts often can replace more traditional metal pieces. Industrial products and daily products rising trend of plastic.
General definition: 2, die in industrial production, with all kinds of press and in a pressure on the special tools, metal or nonmetal materials through the pressure to make the required shape parts or products, this kind of special tools are collectively referred to as mold.
3, the injection molding process description: mold is a kind of plastic products production tools. It consists of several groups of parts, the combination with molding cavity. Clamped injection, mold in injection molding machine, molten plastic injection molding die cavity, and the cavity cooling stereotypes, then separated from mould, via ejection system will leave mould products out of the cavity roof, the mould closed again for the next injection, the injection molding process is a cycle.
4, mold of the general classification: can be divided into plastic mold and plastic mold:
Plastic injection mold are: (1) the seesaw die, forging die, stamping mold, die-casting mould, etc.
A. casting mould, cast iron platform - tap
B. forging die, car body
C. stamping mold, computer panels
D. die mold, super alloy, the cylinder body
(2) plastic moulds according to different production process and production product is divided into:
A. injection molding mould, TV shell, keyboard button (the most common used)
B. blow mold - beverage bottle
C. compression molding mold, bakelite switches, scientific heat-trapping ceramic disc
D. transfer molding mould, IC products
E. extrusion die - tube of glue, plastic bags
F. thermoforming mould molding, transparent packaging shell
G. rotational molding mold, soft plastic doll toys

Swing to draw

Swing setspicture: in a thick shade, flowers blooming garden, a beautiful young woman is swinging the seesaw.Behind her is a pushing a swing, coaxed wife play less experienced.Little wife well-dressed, look carefree, obviously a lot of fun.Long-term happiness without weakness of pushing a swing, see little wife so happy, the in the mind is very happy.However, he never imagined that his wife happy isn't his offer attentive to her, but hidden in the bushes a lad.Boy lies hidden in the bushes, the young woman kept on to him to flirt, are also interested in threw a shoe on your foot towards the young man.It is said that the young man was established famous banker mulberry?Zhu Lian.Obviously, the pint it is intended to show off their this period of "love".This painting represents the noble art interest at the time, careful painted garden scenery, people, trees and flowers painting is very beautiful, too.

Make small electromagnetic swing

On Tuesday, a science teacher assign us to do homework - home to do a small production of science. Returned home, when I think I don't know what to do, my mother gave me a good suggestion: do a small swing, electromagnetic I saw mom, before is really interesting, I need to ask mother to help me to prepare the materials and tools, the materials they need to make their electromagnetic small swings are: two root length of about 20 cm thick wire enameled wire (or thick), about 1 meter long enameled wire, a battery, a piece of hard foam (or board), 2 wire, a magnet, the other is some wrapping paper, small toy doll (you can also use a paper doll), tape and pliers, knives and other tools. First when making the coarse with knives at the ends of the wire insulation slices to 5 cm, bent at right angles, and bent over his head a small circle, the other end into a hard foam do swing bracket, then will be fine at the ends of the enameled wire insulation varnish to about 15 cm, the rest with curved around in circles and forceps rectangularity, scrape off the paint the ends of the remaining at right angles to the short side of the rectangle, bent into a circle on the thick wire circle, put magnet coil below, try to close some, thick wire inserted in the bubble ends connected to wires, and immediately after the battery connection, separation, again contact again apart, can Swing setswing high, final packaging, small toy doll is put on a swing, a pretty little swing is ready. Mother told me that this small swing is the use of electromagnetic force, is the ampere force driven, so called electromagnetic little swing. My this little swing some regret, that is not always swing, mother said that as long as I study hard, not only make the last swing swing, in the future can also be put in when the swing music. How, do you also want to sit on the swing? I will study hard and make the dream become a reality

Principle of swing

Swing setshas two cases:
Sitting in the swing, to push the other one, if only a push, and then just as a simple pendulum swinging back and forth, but because of air resistance, amplitude will be more and more small, but at the same time constant, this kind of situation with the vibration of the pendulum when cannot ignore air resistance; If pushed, swing when swing swinging back to swing a thrust, the amplitude of the swing may be the same or increase, then the vibration of the forced vibration.
The second case is that people usually stand on the swing, squat down and up to swing a driving force, make the Swing setswing, this also is forced vibration. As long as people squat down and set up a perfect balance of time, will swing swing higher and higher, on the contrary, the time to grasp well, you might swing.

Swing - a variant of the swing

In addition to the autumn is the most common means of, some ethnic groups there are many variations on the swing. Xinjiang khalkhas try swinging, locals say "Allah" candy Xie Liqin jake ". In a little clearing choice, with 3 log on a tripod, in 3 ~ 5 meters away another point also build a similar rack, and then a beam between two tripod, about 3 meters from the ground, beam suspension 6 "U" type of ox hair rope, a Swing set. When playing a man and a woman face to face, two people both feet staggered off in the long two ox hair rope, draws two ox hair rope, his arms back on line, double pedal move, the more the higher. Qinghai tu swing with wheels in the autumn. Tu called wheels fall BuRi hot ", meaning "rotation, wheel". Wheels fall according to local conditions, local materials production. If remove the big wheel scooter column, column erected, the car wheel pressure under heavy fixed focus; Round tie on a ladder, fasten isometric leather rope ladder at both ends (like swing), so the "wheels" autumn ". Uygur play swingsmore strange, called "shah Hal", meaning "air wheel", during the spring and autumn season and have a wedding to play. On-court to firm up a log of about 10 meters high shaft, the shaft top be packed in a wooden wheel, wheel with two bar, each fasten ropes, such as swing. One another bar at the bottom of the vertical axis, with rope connected to the top wooden wheel. Games, one on a multipoint rope swing, then bar at the bottom of the both sides, all of several people relative to one another, and the constant push bar, the top wooden wheel rotates. Standing on the rope game that with the acceleration of wheel slowly ascended on high, the faster the speed, the player fly higher.

the ancient swing

Swing setsmainly for women in the palace, the best game in the future or traditional holiday plaza carnival. When the emperor palace in swing; High tang dynasty boundless "backyard swing of emperor han wu fu" cloud: "swing, lucky also. HanWu qi and consent of life, so the harem swings." Swing is mainly in order to keep fit at the time. Palace called swing "fortuneteller play" in the tang dynasty, five dynasties Wang Renyu in its notes the kaiyuan tianbao tian said: "tianbao palace, to the cold, vertical swing, the palace and mocks thought pleasures. Emperor of fortuneteller play, are thus called for citizens.
