5, process: roll molding process (plastic and its composite material processing and molding process has a lot of kinds, in addition to people common extrusion, injection, blow molding process, roll molding is also a kind of processing method of plastic products. Step: (1) first measure the weight of the plastic raw materials into the mold. (2) make the mold along the two vertical axis continuous rotation and heating. (3) the plastic material in the mold under the action of gravity and heat energy, gradually uniform coating, melting adhesion on the whole surface of the mold cavity, forming the required shape. After the cooling and finalizing the product.
6. The picture shows the new double colors: red, yellow, blue and green.
7, with goods distribution: belt + safety hook + high frequency whistle for help! (note: old style does not give oh!!! )
8. The packaging adopts 5-layer corrugated paper box, and the product is wrapped with film.
The new model adopts the internationally accepted rolling molding process, and the steps are as follows:
1. Add the plastic raw materials for quasi-weight measurement into the mold.
2. Continuously rotate the mold along the two vertical axes and keep it heated.
3. Under the action of gravity and heat energy, the plastic raw materials in the mold are gradually coated evenly, fused and adhered to the entire surface of the mold cavity, forming the desired shape.
4, after cooling and finalizing the product.
Process comparison:
There are many kinds of processing and molding processes for plastics and their composites. In addition to the common extrusion, injection, blow molding and other processes, rolling plastic is also a processing method for plastic products. Foreign roll molding industry develops very fast, and domestic due to various factors, such as: slower processing cycle and the limitation of materials used, roll molding industry development speed is lower than other plastic molding industry.
Torpedo rescue buoy should be prepared in the bath, swimming pool, boat, lifeguard, lifeguard station or a specific location, the rope rolled up for carrying, ready to participate in the rescue!
The rope connecting the buoy and the harness shall be tightly wound around the central part of the buoy and the harness shall be inserted into the back two circles of the rope to expose the back head so that the harness can be pulled out of the rope quickly and the rope can be automatically untied in case of rescue.
At the beach, one end of the untethered connection of the rescue buoy is buried in the sand for about 15 cm and fixed upright. On the lifesaving platform or iron frame, the buoy rope harness can be tied up, and then the rear handle of the buoy can be hooked on the rack.
The sea area or the big water area and the moving water rescue person should match to wear the frog shoe. When the rescuer enters the water, he/she should put the suspender over his/her shoulder and put the buoy under his/her arm, or grasp the buoy with one hand and hold the frog shoe with the other hand. Under suitable conditions, he/she should lead the way into the water when entering the water at the beach. The rescuer must always pay attention to the drowning, in order to prevent the loss of the drowning, this is to help the drowning can see the rescuer.

1. We all know that the buoyancy of air is large, and we have heard that many lifejackets made of foam material will still absorb water and lead to the attenuation of buoyancy if they are soaked in water for too long. Similarly, the torpedo buoy made of PE or PVC or EVA foam material will also absorb water and the buoyancy will also attenuate with time. When the rescue unit fails to arrive at the scene of rescue in a minute and a second, the life belt made of foam will slowly absorb water with time, and the buoyancy will slowly decrease. The choice you made at the beginning of the purchase also determines the survival probability of floating on the water. You should consider this important factor before you purchase.
2. The weight of the foam floating strip is too light to throw away the lost rescue opportunity: When you often engage in water leisure activities in streams or lakes, when there is an emergency call for help on the scene, if there is a torpedo buoy at hand, you can immediately throw the torpedo buoy directly to the caller, and you can immediately save him. And general foam article lifesaving float out because is too light in weight easy to mess with the wind wave cannot be effectively controlled when the stroke direction so sometimes have to find a buoy article master article will float swim to HuJiuZhe to rescue effect, but often on time already too late and missed the gold rescue time another swim you send floating people must pay attention to their own physical strength can by back or physical strength overdraft or foot cramps and often the risk of life in life. If you you don't have to personally with the buoy cylinder adventure save people, even if you insist on the buoyancy of water rescue he buoy tube is enough for two or more persons. So choose buoyancy secure your environment Big.
3. The torpedo buoys (barrel) surface drag resistance smaller row water: when dragged torpedo buoys swimmers in the water (barrel) prior to the torpedo buoys (barrel) pointed round design line shape dragged the surface water resistance is small, the torpedo buoys (barrel) front end tip circle design consistent with real torpedo low water resistance design, the design of the head is pointed is to reduce water resistance, in addition the torpedo buoys (barrel) only unilateral semicircular curve contact with the surface of the water and generally identical to the design principle of the bottom is also in order to reduce water resistance.
4. Torpedo buoy (drum) has a long life
Under normal use, if well maintained for more than 3 years or longer
