PP Woven Valve Bag Extrusion line - Gachn, the Efficient and Intelligent Choice for Plastic Weaving Equipment

In the field of plastic woven machinery manufacturing, PP woven valve bags are widely used in the chemical, building materials, grain, and feed industries due to their high strength, excellent wear resistance, and strong sealing properties. In the upstream process of the valve bag production line, the wire drawing machine is a key piece of equipment that determines product quality and production efficiency.

Gachn Group's wire drawing machines are specifically designed for the production of high-quality PP flat yarn. Integrating intelligent, automated, energy-efficient, and environmentally friendly features, they are an ideal choice for many plastic weaving equipment manufacturers looking to increase production capacity and quality.

Why choose Gachn Group Extrusion line?

High-Precision Intelligent Control

1. Equipped with an imported intelligent PLC centralized control system, it supports synchronized speed adjustment across the entire line and individual machine fine-tuning, ensuring simple and stable operation.

2. PID temperature control ensures precise temperature control and more stable wire drawing quality.

Advanced Automation

1. The automatic belt screen changer supports mixing new PP materials with an appropriate amount of masterbatch, ensuring continuous screen change and significantly improving production efficiency.

2. The variable frequency drive system enables high-speed production, with a maximum winding speed of 450m/min.

High-quality finished yarn output

1. The extruder screw and barrel are made of 38CrMoALA high-strength alloy steel, which is wear-resistant and has a long service life.

2. The 4-roller drafting and 4-roller shaping combination achieves drafting speeds of up to 400m/min, producing uniform flat yarn with strong tension.

Energy-saving and environmentally friendly design

1. The total installed power is approximately 600kW, but the actual operating power is only 320-350kW, reducing energy costs.

2. Equipped with a side yarn crushing and recovery device, it reduces waste, ensuring environmental protection and high efficiency.
