 Poly Foam Filled Tire's Production Technology: SPIN-Cast Molding

The process of spin-cast molding is used to insert foam fill into tires. This process helps create a dense, firm tread area while keeping the sidewall area flexible. The distribution of the foam fill is even and accurate ensuring excellent shock absorption. This helps provide the user with a smooth ride, every time.

 How To Check The Air Void Inside Foam Filled Tyres After Foaming PU?

Technology: we do a full tire shaping process before production. Our filling process uses centrifugal rotation to uniformly fill the PU raw materials into the tires and fully realize complete bonding between the tire and PU Foam, thus avoiding any air voids inside.

Every time replacing the material or starting the machine, we will cut one tire to check the inside of the tire to ensure there are no air voids or separations in the product.

All of the products can meet the requirements of ISO7176 standard and have passed the testing requirements of ROHS and REACH. Some of them can even meet the German GS standards for children's products.
