Seamless welding process

Seamless welding technology in the welding mold showed excellent performance and improved a considerable part accuracy, finish and appearance, to shorten the manufacturing cycle of the mold.

Overcoming the mold aesthetic shortcomings that has welding and affect the joints.

With the growing global market demand for high-quality parts, people are increasingly turning to the seamless welding technology can improve the accuracy of parts. Seamless welding technology can not only help eliminate mold weld, but also to improve the accuracy of parts, finish and appearance of the same time, the seamless welding technology implement efficient control and shorten the processing cycle of the mold in the injection molding process. Because of the technology products with excellent surface finish, so there is no need to adopt the second sputtering and annealing, to avoid dimensional changes caused by the secondary contraction.

In the mold production process, the cooling lines arranged in the vicinity of the mold surface, the surface finish of the product is always less uniform. The new process, the flow of the mold core and cavity cooling lines near the resin injection region can make the quality of products to get a better guarantee.

The new seamless welding techniques used in modern machine tools and some new technology. In accordance with the process requirements of the new technology, processing similar to the mesh of the mold core and cavity, the fourth axis milling machine in order to avoid its movement and the second fixture, which can improve the tolerance of dimensional accuracy.

The board of fins and the water chamber cooling lines to be more widely applied to further improve product quality and seamless weld finish.

Seamless pipe Specification, standard and identification

Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.
