Recently, the second phase of the Xiangshan Factory project has completed the main construction and is about to enter the plant capping stage. This project is specially designed and constructed to meet the requirements of the production, manufacturing and manufacturing of Qinding Company's large-scale IXPE foaming furnace production line. The total height of the factory building is 18.35m, with a single span of 8m. Each span of the workshop will be equipped with two 32-ton cranes with a maximum lifting height of 13.5m. After the construction is completed, it will be able to start production of 4 IXPE foaming furnace production lines and 3 XPE foaming production lines at the same time; it will have an annual production capacity of 32 XPE foaming production lines or IXPE foaming production lines.

Recently, the ultra-wide XPE foam production machine ordered by foreign company from Qin Ding Company has begun to enter the assembly stage. This XPE foaming production machine is a horizontal foaming production line. The target XPE coil specifications are a maximum thickness of 15mm and a maximum width of 3000mm. To this end, the effective width of the foaming furnace designed by our company is 3500mm and the length of the furnace body is 25M. This foaming furnace can produce products with a maximum thickness of 20mm, a maximum width of 3200mm, and a maximum output of 5.5~6T/24h.

This IXPE foaming production line includes the following components: unwinding machine, special feeder for IXPE foaming machine, horizontal foaming furnace, vertical foaming furnace, vacuum adsorption expansion mechanism for IXPE foaming machine, furnace mouth traction machine and five-roller cooling machine, A complete IXPE foaming unit such as a special sheet tractor for a foaming machine, a special winding machine for a foaming machine, etc.

In mid-August 2023, HNREY, the project manager of our company's IXPE foam production machine line, led the commissioning engineers to go abroad to debug a set of IXPE foaming machine line.

This IXPE foaming production line includes the following components: unwinding machine, special feeder for IXPE foaming machine, horizontal foaming furnace, vertical foaming furnace, vacuum adsorption expansion mechanism for IXPE foaming machine, furnace mouth traction machine and five-roller cooling machine, A complete IXPE foaming unit such as a special sheet tractor for a foaming machine, a special winding machine for a foaming machine, etc.

The XPE foaming machine line installed in Linyi adopts the traditional XPE foam production process. The whole set of XPE foaming machine line includes granulation unit, mother sheet extruder unit and horizontal XPE foaming furnace unit. It can produce XPE foam products with single layer thickness of 2~25mm and width of 1800mm. In addition, this project is equipped with a complex machine unit. Through thermal lamination, the thickness can be increased to a max thickness of 100mm ultra-thick XPE.

From August 1st to 2nd, 2021, the IXPE gas heating foam machine signed by a large foreign enterprise company and Qin Ding Company was delivered. A total of 8 containers are shipped this time. The entire production line includes a discharger, a storage device, a tractor, a gas-heated horizontal foaming machine, a gas-heated vertical foaming machine, an exhaust gas recovery integrated heating unit, and a vacuum expansion unit. , Five-roller cooling unit, surface treatment unit, correction unit, trimming traction unit, winding unit and corresponding frame.

The molding methods of polyethylene foam include extrusion, injection, molding, orientation and other methods. Among them, the extrusion method is divided into direct extrusion foaming and cross-linking foaming after extrusion. After extrusion, cross-linked foaming can be divided into chemical cross-linked foaming, physical cross-linked foaming and mixed cross-linked foaming.

Recently, the gas-heated IXPE foaming machine purchased by a large Korean PVC plastic floor manufacturer from our company is about to complete the factory production stage and is expected to be shipped in early July.

Because IXPE products are thin, such as the use of XPE/XLPE's horizontal and continuous foaming machine structure, it is prone to failures such as sticking or breaking during the foaming process. For this reason, our predecessors have specially developed a foaming machine structure that combines a horizontal furnace and a vertical furnace: the IXPE extruded mother sheet is preheated in the horizontal furnace section and enters the vertical furnace section when it is foamed. The IXPE extruded mother sheet is naturally It sags, and the blowing agent decomposes at high temperature, so that the IXPE extruded mother sheet expands naturally in the vertical foaming furnace, and a perfect IXPE foam product is obtained. The foaming furnace of this process is the IXPE vertical foaming furnace.
