Product Introduction

In the large flexible container processing field, mass welding of PVC water storage bags and children's swimming pools often faces two major challenges: Manual splicing is extremely inefficient (a 10㎡ water storage bag takes 3 hours) with seams prone to cracking and leakage; ordinary equipment has limited working width, unable to adapt to extra-large PVC materials, resulting in insufficient sealing of finished products.

This Large PVC bag welding machine is designed to solve these pain points: Equipped with an extra-long stroke welding platform, it can stably fuse extra-wide PVC materials, increasing seam fusion strength by 50% and reducing leakage rate to below 0.1%; combined with an automatic walking table system, it enables continuous large-area welding, shortening the processing time of a 10㎡ water storage bag to 40 minutes-350% more efficient than traditional methods. It also has a built-in intelligent spark protection to avoid material scalding, making it a core processing device for large mine water storage and outdoor pool production enterprises.

Product Features

Wide-Width Stable Fusion Technology: Supports fusion of PVC materials with a width of over 2 meters, with a seam fusion depth of 2mm and tensile strength increased by 40%, fully meeting the pressure and sealing requirements of water storage bags and pools.

Automatic Walking Table Continuous Operation: The extra-long stroke table with automatic feeding can continuously complete seamless welding of over 50㎡ materials, increasing single-shift processing volume to 4 times that of traditional equipment.

Intelligent Spark Protection System: Real-time monitoring of the fusion area; cuts off high-frequency output in 0.2 seconds when sparks appear, avoiding PVC material scalding and damage, reducing defective rate by 90%.

Application Scenarios

Large PVC Water Storage Bag Processing: Traditional manual splicing is inefficient with high leakage rates. This machine completes welding of a 10㎡ water storage bag in 40 minutes, with 99.9% seam waterproofness, suitable for water storage in mines and farmlands.

Children's PVC Pool Production: Ordinary equipment cannot adapt to large-area pool splicing. This machine's wide-width fusion ensures seamless pool seams, increasing tensile strength by 40% and avoiding cracking risks during use.

PVC Waterproof Tarpaulin Splicing: Manually spliced tarpaulins are prone to leakage in wind and rain. After fusion by this machine, the tarpaulin seam reaches IPX7 waterproof level, suitable for large outdoor covering scenarios.

FAQ

Q: What PVC products can the machine process?

A: It is core-adapted to large PVC water storage bags and children's pools, and also supports welding of large-area products such as PVC waterproof tarpaulins and flexible bulk bags.

Q: How is the waterproof performance of the fused seams?

A: The seam fusion depth is 2mm, and it passes 1.2MPa water pressure test without leakage, fully meeting the sealing requirements of water storage and pools.

Q: What is the thickness range of PVC materials supported by the machine?

A: It adapts to PVC materials with a thickness of 0.5-3mm; different thicknesses can be adapted by adjusting fusion parameters without replacing core components.

Q: How long does it take to train new employees to operate the machine?

A: The machine is equipped with preset parameter templates; new employees can independently process simple products in 1 hour after learning table operation and parameter adjustment.

Q: What is the warranty policy for the machine?

A: The whole machine has a 12-month free warranty; core components such as the high-frequency generator and walking table system have a 6-month warranty, with lifelong maintenance services.

Q: Can welding molds of different widths be customized?

A: Molds with a width of 2000-3000MM are supported; molds can be made with product dimensions, and replacement takes only 15 minutes.

Q: What shipping options are available for the machine?

A: It is shipped by sea (Yantian Port, Shenzhen) by default; land or air freight is also available, adjustable according to delivery time needs.

Q: Is the machine's energy consumption high?

A: It uses intelligent power adjustment, automatically reducing power when idle. Energy consumption is 20% lower than traditional equipment, saving electricity costs in long-term use.
