  • Plastic ball, hollow plastic ball Plastic ball, hollow plastic ball

    Plastic balls are collectively referred to as plastic floating balls, plastic hollow balls, and plastic solid balls. Plastic balls are now widely used in the market. Plastic balls have the characteristics of lower density than metal balls. Plastic balls of different plastic materials have different densities. Between 0.83 g/cm³-2.2g/cm³, corresponding plastic materials can be used to produce plastic balls according to different needs. Plastic floating balls include plastic hollow balls and plastic foam balls. The manufacturing process of plastic hollow balls is mainly divided into For the blow molding process and the welding process, the plastic hollow balls produced by the plastic welding process have the characteristics of high precision, good compressive strength, and multiple material choices. The plastic foam balls are basically not stable because of the unstable density and low yield rate. Being eliminated, there is also a biodegradable plastic ball among the plastic balls. The biodegradable plastic ball is mainly used in the field of oil extraction and used as a sealing ball in the underground oil production operation. This kind of plastic ball is called soluble fracturing. Plastic balls, after the fracturing operation is completed, the fracturing plastic balls can be degraded downhole by themselves and do not need to be drained back to the well, which improves oil production efficiency and reduces the cost of oil production operations. PA plastic balls are mainly used in the automotive field. Because PA plastic balls have the characteristics of oil resistance, high temperature resistance, high strength and good toughness, smooth surface and long service life. PP balls are mainly used in the fields of food and medicine. PP plastics are environmentally safe and safe. Therefore, they are widely used in the field of medical equipment and food processing. POM plastic balls have high hardness, smooth surface and good self-lubricating properties. They are more used in slide rails. Category products above.


  • Plastic ball types and various types of plastic ball simple process: Plastic ball types and various types of plastic ball simple process:

    Plastic ball types and various types of plastic ball simple process:

    Plastic Balls, Plastic Hollow Balls, Plastic Hole Balls, Plastic Jump Balls, Plastic Yo-Yo Balls, Plastic Foam Balls Balls, Plastic Level Balls, Plastic Fracturing Balls, Plastic Microspheres, Plastic Alloy Balls, Plastic Billiard Balls, Plastic Crystal Balls,  Plastic Night Balls, Plastic Laundry  Balls, plastic chemical balls, plastic plating balls, plastic paint balls, plastic fire balls, plastic BB balls, plastic slide balls, etc.

    There are the following processes for producing plastic balls:

    1. Plastic injection molding ball process production: The plastic ball mold is first processed into a plastic hair ball with an injection molding machine, and then the plastic ball is ground through a plastic grinding ball machine, mainly to remove the plastic batch ball batch wind and the mold clamping line. And processed into a certain accuracy, so that the plastic ball into a plastic precision ball.

    2. Plastic foam ball process production: The plastic raw materials and plastic foaming agent are mixed in a certain proportion, and then put into a special plastic foam injection molding machine for injection molding, foaming agent and plastic raw materials in the plastic foam injection molding machine heating up Simultaneously, a chemical foaming reaction is generated between each other, and then the foamed plastic raw material is injected into the plastic ball mold through a certain pressure and speed. After the melted plastic material enters the mold, it is solidified into a plastic ball and the mold is opened. Good plastic foam ball.

    3. Production of Plastic PVC Ball Glue Glue: Glue gluing machine is generally used for doll toy equipment. It is less used to produce plastic balls and plastic hollow balls. The first material used for plastic PVC ball is powder, and it is mixed with a certain proportion. The plasticizer puts the paste-like plastic liquid into the plastic PVC ball mold, then puts the plastic PVC mold into the silicone oven and can rotate on the 360-degree rotation bracket, and then makes the liquid by continuously heating. The plastic solution is solidified on the inner wall of the plastic PVC mold. After all the plastic liquid is completely solidified, the silicone oven is opened, the mold is taken out and put into water to cool. After the cooling is completed, the mold is opened to take out the plastic ball, which is the finished plastic PVC ball.

    4.Plastic ball casting process production: The material used for this type of plastic ball is phenolic resin or unsaturated resin, and it is mixed with solidified liquid. The curing liquid is the function similar to glue. After the resin is mixed with the curing liquid, The liquid is poured into the plastic ball mold, waiting for the liquid to solidify in the mold to complete curing. This kind of plastic ball process is relatively simple, but it has a certain influence on the environment and has a large irritating odor, so such a plastic ball factory needs Apply for a special production license.

    5. Plastic super ball rotomolding production process: plastic super ball can not be produced with conventional injection molding and blow molding process, because the product is too large, and the demand is not large, it is difficult to have a specific production equipment to match, so the use of rotomolding Process production, simply put, the plastic super ball mold has a 360-degree rolling and heating function, the first production of raw materials is plastic powder instead of granular plastic materials, put a certain weight of plastic powder in plastic super ball mold, and then The heating makes the mold rotate 360 degrees. As the temperature of the mold increases, the plastic powder in the mold begins to melt. Because the mold is heated, the plastic powder that is first melted is close to the inner wall of the plastic mold. When the plastic powder is located When melted and adhered to the inner wall of the mold, the plastic large ball is basically formed. After the mold is slowly cooled, the plastic ball is removed, and the plastic super ball is also produced.

    6. Blow molding process to produce plastic hollow balls: Small plastic hollow balls are basically produced by a plastic blow molding machine. The quantitative plastic material is melted and put into a plastic hollow ball horizontal tool. Then a plastic needle is inserted through a needle. Pressurized inflation is carried out. When the plastic material is fully inflated to fill the entire mold, the needle tube is withdrawn and the plastic hollow ball is cooled in the mold for 10 seconds. Then the mold is opened and the plastic hollow ball is also produced.


  • Hollow plastic ball Hollow plastic ball

    The manufacturing process of hollow plastic balls is much more complicated than that of solid plastic balls. The manufacturing methods of hollow plastic balls are as follows:

    1. Ordinary plastic hollow spheres are manufactured by blow molding process. The plastic hollow spheres produced by blow molding process are generally aimed at plastic hollow spheres with low quality requirements, and plastic hollow sphere products without special requirements for appearance and strength. Plastic hollow spheres have strong material selectivity. Only PP and PE materials can be used to produce plastic hollow spheres, and the thickness of plastic hollow spheres cannot be precisely controlled, and there is a phenomenon of uneven wall thickness of plastic hollow spheres. Blow-molded plastic hollow spheres are often used in fillers or plating solutions for covering applications.

    2. Plastic hollow spheres are manufactured by bonding technology: to make two plastic hollow hemispheres, the joints of the plastic hollow hemispheres should be buckled accordingly. First, apply glue to the buckles of the two plastic hemispheres, and then Buckle the two plastic hemispheres together and place them until the glue has solidified. The finished plastic hollow plastic ball is the finished plastic hollow plastic ball. The plastic ball produced by the gluing process is not strong, sensitive to temperature and easy to crack under high and low temperature conditions, so Practicality is not very strong.

    3. Manufacturing of plastic hollow sphere welding process: firstly, two plastic hemispheres must be manufactured. The difference from the plastic hemisphere used for gluing is that there is no need to buckle. First, the two hemispheres must be put into a set of welding molds. The joints will be thinner. Put the assembled molds in a special furnace for heating. When the plastics at the joints are melted and fused together, take the molds out to cool, and take out the hollow plastic balls to be semi-finished plastic hollow balls. After passing the semi-finished plastic hollow ball through a dedicated hollow plastic ball grinding machine, the seam of the processed precision hollow plastic ball is integrated with the rest of the plastic ball. There is no difference in strength, the wall thickness is the same, and the appearance is beautiful. It is also the best manufacturing method for precision plastic hollow balls.

    4. Ultrasonic welding process of plastic hollow ball: ultrasonic welding plastic hollow ball also uses two plastic hemispheres for ultrasonic welding, but the plastic hollow ball of ultrasonic welding needs to make the corresponding buckle of the two hemispheres in succession. During ultrasonic welding Two semicircular hollow plastic spheres should be buckled together first, and then placed under the ultrasonic machine for ultrasonic welding. The plastic hollow spheres for ultrasonic welding have very little material selection and can only be welded with hard plastics, and the welding strength is not high. , Ultrasonic welding technology is suitable for plastic hollow spheres that require strength.


  • Physical properties of PE plastic ball Physical properties of PE plastic ball

  • airsoft bb materials commonly used material statistics airsoft bb materials commonly used material statistics

    Plastic airsoft bb special filling barium sulfate powder

    Barium sulphate has high specific gravity, chemical stability, and is insoluble in water. Therefore, many manufacturers have long been used as airsoft bbmaterials. Generally, barium sulfate is used to increase airsoft bb. Strontium sulphate is an ore powder, which has no pollution to the environment and the price is low. By filling the airsoft bb, in addition to increasing the weight, the surface finish of the airsoft bb is also sufficiently improved.

    Plastic airsoft bb special calcium carbonate

    Calcium carbonate is the most commonly used filler in the plastics industry. It is inexpensive and can improve the physical properties of plastics. Therefore, its use is very extensive. Calcium carbonate is mainly added to increase the weight and surface finish because calcium carbonate is very fine and plastic is added. The voids in the plastic can be fully filled in the airsoft bb, so that the airsoft bb produced is exceptionally smooth, so the good airsoft bb is filled with calcium carbonate.

    Biodegradable airsoft bb material PLA (polylactic acid)

    PLA (polylactic acid) as a naturally degradable plastic is widely used in the plastics industry. As a consumable, airsoft bb is also a disposable product. It cannot be recycled and reused. If airsoft bb cannot be degraded, leaving it in the soil will cause With large environmental pollution, the time for complete degradation may be several decades. However, the time for natural degradation of airsoft bb produced by PLA (polylactic acid) can be shortened to several months. Therefore, PLA is widely promoted abroad. Lactate) BB, PLA (polylactic acid) generates water and carbon dioxide after degradation, and there will be no residual pollutants. With the environmental protection consciousness and policies and regulations, PLA will become more and more popular.

    It is also a biodegradable material that uses PLA as its main component airsoft bb.

    PP (polypropylene) PE (polyethylene) airsoft bb

    The most significant advantages of PP and PE are the low price and easy control of the production process. The production of BB by adding calcium carbonate or barium sulphate has a cost advantage in terms of price, but the disadvantage of this airsoft bb is that the hardness is not enough, and the surface finish is slightly In some cases, only 

    PP (polypropylene) PE (polyethylene) airsoft bb products produced by large-scale airsoft bbfactories are of higher quality. The basic reason is that the production facilities of the small factories are simple, which simplifies many production processes and results in inferior quality of airsoft bb produced by small factories. Can not meet the requirements of high-end customers.


  • airsoft bb grinding machine airsoft bb grinding machine

    airsoft bb grinding machine working principle analysis

    There are three types of machines for BB shell grinding: airsoft bb coarse grinding machine, airsoft bb grinding ball machine, airsoft bb grinding machine

    1.airsoft bb coarse grinding machine is a simple machine to remove batch wind and burrs of airsoft bb blanks, in order to ensure that the airsoft bb grinding ball machine will not be burred by the airsoft bb blank ball into the grinding wheel of the grinding ball machine, if it enters the burrs in the grinding wheel. The airsoft bb will be squeezed, and then the grinding wheel grinding wheel will wear the blank into an ellipse, resulting in uneven airsoft bb blank surface, which affects the accuracy of the airsoft bb and the subsequent polishing effect.

    2.airsoft bb grinding ball machine grinds the airsoft bb that has gone through a burr to a diameter of about 6mm, but the accuracy does not reach the accuracy required by airsoft bb. The accuracy required by BB is 5.95mm plus or minus 0.01, and the airsoft bb ball grinding machine grinds the ball. The ball machine accessories have high precision requirements. The upper grinding plate must be machined into a triangular groove with a depth of 6.5mm deep using precision lathes. The tolerance cannot exceed 2mm. The grinding wheel of the lower grinding plate must be machined with a special grinding wheel machine to produce grooves. Accuracy also requires a tolerance of about 2mm,

    3.airsoft bb grinding machine is the final precision machining of the airsoft bb after the grinding machine, the grinding machine on the grinding board is a good grinding board and then plated alloy, this grinding disc is high precision, and wear-resistant, under The same metal plate of the grinding plate is electroplated. The BB refiner requires workers to constantly adjust the machine and check the size. The airsoft bb grinding machine is equally important as the worker's technology.

  • airsoft bb Reasons for the generation of air holes airsoft bb Reasons for the generation of air holes

    airsoft bb Reasons for the generation of air holes

     Since airsoft bb is an opaque plastic BB ball, there is no air hole in the middle, and it cannot be seen in appearance. However, the airsoft bb with a stomata in the middle has a great influence on the accuracy of shooting. Now the detection of the air hole in the airsoft bb is based on sampling. airsoft bb cut from the middle of the pliers, you can clearly see there are no pores, and the location of the pores, pore formation for the following reasons:

    1.airsoft bb mould reason: Due to the unreasonable design of the mold runner, when the airsoft bb blank billet is molded, the air in the cavity is too late to be discharged outside the mold, and this part of the air hole will be trapped in the airsoft bb blank shell to form the air hole.

    2. Reasons for airsoft bb material: In the production process o fairsoft bb, the BB granulator is a strip-brick water-cooling method to make airsoft bb material. If it stays in the water for too long, airsoft bb material will absorb too much water in the airsoft bb injection molding. During molding, this part of water will turn into water vapor and cannot be discharged to the outside of the mold. This part of the water vapor will remain in the blank of the airsoft bb blank to form pores.

    3.BB forming speed reasons: airsoft bb injection molding, if the firing speed is too fast, the cavity within the climate too late to die out of the mold, the formation of trapped gas, this part of the climate will remain in the BB blank bomb inside the formation of air holes.

    4. Reasons for high injection molding temperature: When the airsoft bb is injected, the temperature of the injection molding machine is set too high, causing the BB raw material to flow too high. When the injection molding, the natural firing rate will be very fast. When the airsoft bb plastic material is as fast as water Inflow mold, naturally there will be a part of the climate outside the mold, the formation of air holes, and airsoft bb material flows into the mold, the surface cooling, but the airsoft bb rough ball is still softened in the middle, the existing climate can not be evenly dispersed throughout the airsoft bbblank bomb , can only exist in a position in the middle of the airsoft bb blank bomb, forming a blowhole.

  • A brief introduction to airsoft bb A brief introduction to airsoft bb

       Airsoft bb is a plastic ball used for the firing of pneumatic toy guns and electric toy guns. The most commonly used specification is 5.95mm. The material is steel balls are plated with copper or galvanized. Airsoft bb is usually a copper or galvanized steel ball. The material used for the plastic materials Airsoft bb and Airsoft bb is different from that of the shooting gun. The firing accuracy is also very different. The plastic Airsoft bb will be faster due to the lighter initial velocity, but it will be easily deflected by the air resistance. The initial velocity of Airsoft bb is slower, but it is less affected by air resistance and the accuracy will be higher. The modern process of producing plastic Airsoft bb is filled with weight-increasing stone powder, making the weight of the Airsoft bb bullet into a variety of freely selectable BBs. The user can select Airsoft bb according to the needs of his own gun, and the plastic Airsoft bb will break after hitting the target. Cracking does not cause harm to people. Therefore, the plastic Airsoft bb shell gradually replaces the metal BB. The disadvantage of the ordinary plastic Airsoft bb is that it is not easily decomposed. The residual Airsoft bb after field shooting will cause soil pollution, and now there is a kind of biodegradable plastic. The manufactured Airsoft bb completely solves the problem of environmental pollution. The material of this Airsoft bb is processed by PLA. Degradation of Airsoft bb in the soil takes more than three months and can be completely decomposed by bacteria in the soil to generate carbon dioxide and water. There is no pollution to the environment, so now the general foreign Airsoft bb market is being replaced by a degradable Airsoft bb.
