First Tank Movable & Dual Cooling – PP Strapping Extrusion

This production line features a dual-stage cooling system consisting of a first cooling water tank and a secondary cooling water tank. The first cooling tank is 3.5m long and can be moved forward/backward and up/down for precise alignment with the die outlet. It contains multiple sets of sizing tracks to keep the 6 strands parallel during cooling. The tank uses a honeycomb water inlet for uniform, smooth flow and an adjustable water level to suit different tape specifications. The secondary cooling tank is 5.5m long with adjustable water temperature from 10-25°C for low-temperature precision cooling. The dual-tank design enables staged cooling ("rapid setting + low-temperature precision cooling"), effectively controlling crystallinity, reducing internal stress, and improving product dimensional stability.

• First tank fully movable: Forward/back and up/down for easy die alignment
• Honeycomb water inlet: Smooth, laminar flow avoids turbulence and bubble impact
• Adjustable water level: Optimizes cooling depth for different tape sizes
• Multiple sizing tracks: Prevents interference or tangling among 6 strands
• 304 stainless steel: Corrosion-resistant, easy to clean, rust-free
• Dual-stage cooling: First tank for rapid setting, second for low-temperature precision
• Secondary tank temperature adjustable: 10-25°C for different materials and products
• Lifting motor: Smooth, effortless height adjustment
• Reduced internal stress: Staged cooling lowers product stress, improving toughness
• Dimensional stability: Uniform cooling ensures consistent width/thickness
