Product Introduction

Introduction

Detailed Description

● As a high-efficiency Two-way Corona Machine, it also functions as a practical Double-Station Corona Machine, featuring dual corona treatment heads that process both sides of materials simultaneously-cutting treatment time by 50% compared to single-sided models, a key advantage of Two-way Corona Machine designs. It handles material widths 500-2000mm and thicknesses 0.01-1.5mm, with adjustable corona power (1-15kW) to match different plastic types, ensuring surface tension reaches 38-52 dynes/cm for strong adhesion.

● Equipped with a servo-driven conveying system, it maintains stable material speed (5-50m/min) to avoid stretching or wrinkling-critical for thin plastic films. The Double-Station Corona Machine structure allows one station to load/unload materials while the other operates, minimizing downtime and boosting productivity to 800+ meters per hour. A photoelectric edge-tracking sensor corrects lateral deviations in real time, ensuring uniform treatment across the material surface.

● The machine uses a high-frequency oscillating circuit to generate corona discharge, which modifies plastic surfaces without damaging their physical properties-a gentle yet effective process inherent in Two-way Corona Machine. A built-in voltage stabilization system prevents power fluctuations, maintaining consistent treatment quality. It also integrates a cooling fan for the corona heads, extending their service life to 5000+ working hours.

● Operation is user-friendly via a 7-inch touchscreen HMI, which displays real-time parameters (power, speed, surface tension) and stores 50+ process recipes for frequent materials. Safety features include emergency stop buttons, high-voltage insulation protection, and a safety cover for the corona area-meeting CE and ISO standards, similar to reliable Double-Station Corona Machine specs. Its compact size (2800×1200×1800mm) fits workshop layouts, with low noise (≤75dB).

● Optional accessories: a surface tension tester (on-site quality check), a material winding/unwinding unit (for roll-fed materials), and a dust removal brush (cleaning surfaces before treatment). Built with premium components (Siemens servo motor, Schneider electrical parts), it has an average failure rate below 2% per year. A 12-month warranty covers parts and labor, with on-site technical support-making it a cost-effective choice for manufacturers seeking consistent, efficient plastic surface treatment.
