TZ1600-35 2-Sides 2-Coatings Aluminium Production Line (Separated)

Coating line features:

Model TZ1600-35 coating line (separated structure) is suitable for certain coating factories. 2-sides 2-coating coating products in thickness range 0.15mm~0.6mm applies to most ACP material, roofing and ceiling material. Model TZ1600-35 coating line is high quality coating line, good performance in all kinds of paint coating. Separated structure is flexible in production, pretreatment process and coating process are separated and non-interfering, so that production is much easier to plan or schedule. Operation faults and equipment problems effect is less.

A primary reason to choose separated structure is its advantage over dimension, Model TZ1600-35 requires only 85m×18m×7m workshop.

Application: For coating aluminium coil of ACP(Aluminium Composite Panel), roofing , cladding, ceiling,roller shutter,etc.

Advantage: Widely usage range, short line, smaller dimension workshop needed,  less operation faults and equipment problems effect .

2. Basic Production Process

Coating line

Coil loading → Uncoil machine → Sewing table → Topside primer-paint roller-coater → Curing oven 1 → Air cooling → CPC 1 → Tension device 1 →Topside 2-coat and backside roller-coater → Curing oven 2 → CPC 2 → Tension device 2 → Coil machiner → Coil discharging

Pretreatment line

Coil loading → Uncoil machine → Sewing table → Acid washing, brushing roller → Water washing → Deionized water washing → Drying → Roller-coating chromizing → Drying → Cooling → Tension device → Coil machine → Coil discharging

Rewinding line

Coil loading → Uncoil machine → Sewing table → Tension device → Coil machine → Coil discharging
