The difficulties include technological process is too long, material is easy to become yellow； bending direction of each cavity is inconsistent and the discharge of each cavity is unstable. Using patent design channel, Aona can successfully solve the above problems.

Calibrator is the key factor to affect the extrusion speed. Aona uses segmented and progressive shrinkage of design concept, all water vapor holes are processed by high-precision gun drill with high precision, the distance between the hole and the cavity is only 3mm, and the cooling efficiency is high. Because of the high smoothness of inner hole, impurities are not easy to stick, prolonging the on-line production cycle of the tooling.

All kinds of telecommunication toolings: radome tooling, plum tube tooling, nine-hole tube tooling, channel tooling, etc.

Various shapes of auto parts toolings: curved surface embossing tooling, multi face embossing tooling, glass bead front co-extrusion tooling, glass bead post co-extrusion tooling, etc.

​Using imported pin sleeve for positioning device, and the clear ance is not easy to change, even it is repeatedly disassembled up to 10,000 times, ensures the stability of die discharge; Die is equipped with guide pillar to prevent workers from damaging the tooling during disassembly, and also increase the long life of the Tooling.

​Using coat hanger type flow channel, manual or automatic flexible die lip adjustments control precisely the thickness of the film and ensure a uniform and perfect film product.

The difficulty design of foam WPC profile tooling lies in the pressure of die. Reasonable pressure design can ensure the profile density, foam uniformity and production stability; Aona provides special toolings according to the formula characteristics: hard surface foam tooling, co-extrusion foam tooling, steel & plastic co- extrusion foam tooling, PVC &WPC foam tooling, PE &WPC Tooling, etc.

Aona adheres to the design concept of "the pressure is consumed at the die lip outlet as much as possible". In this way, the designed runner always has pressure without material stagnation.The co-extrusion surfoce brightness is high and the production is stable. If there are special requirements for the surface brightness, flexible heating strip can be added at the die lip outlet to meet the personalized needs of customers.

Because of wide vacuum groove and high adsorption resistance of the traditional pipe sizing sleeve, leads to large subsequent traction and unsatisfactory roundness. Aona breaks the traditional processing method, adopts narrow groove vacuum, with small production resistance and perfect roundness.

​Using integral diverter shuttle patent channel, not only ensure stable production at low speed or high, but also avoid leakage of material of die. The special design is well received among customers.
