Weifang Kaide Plastic Machine successfully developed a series of high-speed pipe production lines

Recently, Weifang Kaide Plastic Machinery Co., Ltd., which has rich experience in the production of PE-Xb, PE-RT and PP-R pipe units, draws on the best technology from abroad.

• 2007 floor rookie imitation solid wood and super solid wood flooring into the mainstream • Shunde two plywood companies rank among the top 50 in China • Wazhou has become the largest supplier of ceramic machinery enterprises in Asia • Ceramic sanitary ware industry will undergo great changes in the next 10 years

Based on the company's existing technology, a high-speed extrusion unit for heat-resistant polyethylene PE-RT, one-step silane cross-linked polyethylene PE-Xb and PP-R pipe has been developed (production speed of φ20mm pipeline is up to 30m/min).
The unit adopts large aspect ratio extruder (33:1). The screw adopts PE-RT, PP-R special BM barrier type mixing screw or PE-Xb special cross-linking reaction type screw. The screw removal and cleaning is convenient and quick. Because the design of the screw structure is more reasonable, the extrusion yield and plasticizing quality are greatly increased, which is very beneficial to the stable and rapid extrusion of the material; the barrel is a two-stage structure with a forced feeding section and circulating water cooling; The main motor adopts DC motor and imported DC governor for speed regulation; the specially designed inner cavity of the extrusion die is more suitable for the head pressure of PE-RT, PE-Xb or PP-R, effectively eliminating the splitting of the pipe. The traces greatly enhance the anti-blasting pressure of the pipe; the vacuum sizing sleeve adopts the high-speed special multi-chip superimposed combined water bath vacuum shaping structure unique to our company and has applied for three patent protections, achieving high-speed production, high-efficiency shaping and High stability, improve the accuracy of the various dimensions of the pipe, make the subsequent operation easier to control; the setting table adopts negative pressure vacuum setting, equipped with automatic water inlet and drainage system, and the cooling mode is a new type of full-range infiltration cooling, cooling medium Fully and comprehensive contact with the pipe to adapt to the high line speed of the pipe; the tractor adopts multiple sets of cylinders full-roller clamping mode, equipped with high-speed wear-resistant belt, and imported frequency converter frequency control, ensuring smooth and uniform traction of the pipe, especially The high-speed traction completely subverts the jitter phenomenon of the traditional rubber-type tractor; the coiler is a double-station coiler driven by a torque motor; the whole line is controlled by an imported brand-name PCC programmable computer control system, realizing the true meaning. Precision control and high synchronization.

High-speed PE-RT heat-resistant polyethylene pipe unit

It is reported that CapitaLand has successfully sold as many as 78 PE-Xb production lines and 23 PE-RT special pipe production lines.
