The double-layer glazed tile forming machine 25-28 is a specialized equipment for producing antique style roofs with double-layer and simultaneous/switching of upper and lower layers. "25-28" refers to classic small corrugated glazed tiles with a wave height of 25mm and an effective coverage width of 280mm (the upper layer is mostly 828/850 glazed tiles, and the lower layer is equipped with 900/1000 flat or curved tiles), suitable for 1000-1250mm color coated rolls. It is characterized by small tile shapes, tight overlapping, and high cost-effectiveness, and is widely used in roof projects such as villas, ancient buildings, new rural areas, and garden pavilions.

Core technical parameters

• Hydraulic shearing system: rear cutting design, double-layer independent cutting, smooth and burr free cutting, precise length, and durable blade.
• PLC control system: Delta PLC+touch screen, one click parameter storage, fault self check alarm, single person operation, easy to learn.
• Discharge rack: 4-6 meter double-layer pallet, scratch resistant, convenient for collecting and transporting finished products.

Core advantages

Compact tile shape, strong waterproof performance

• 25mm wave height+280mm effective width, fine ripples, high overlap, less likely to leak than large tile types, suitable for rainy areas.
• The upper layer has a coverage width of 828/850mm, with high material utilization, few joints, and fast construction.

Dual use, economical and efficient

• A set of equipment simultaneously produces antique glazed tiles and practical flat tiles, saving 30% of land and 40% of investment, suitable for flexible production of small batches and multiple orders.
• Double layer independent drive, capable of single layer operation or dual layer simultaneous production, with fast order delivery.

Precise and durable, stable molding

• Solid shaft+hard chrome plated rolling mill, wear-resistant and scratch resistant, long service life, long-term operation without shaking or deformation.
• CNC precision machining rollers with a size error of ≤ 0.5mm, consistent tile shape, seamless overlap, and beautiful installation.

Automation saves labor

• PLC intelligent control, one click setting of length, quantity, and speed, beginner can get started in 1 hour, single person on duty.
• Variable frequency speed regulation, smooth operation, low noise, energy saving of over 30%, daily output of 2000-3000 square meters.

Application scenarios

• 25-28 glazed tiles (upper level): villas, antique commercial streets, temple ancient buildings, garden landscape pavilions, new rural renovation roofs.
• Flat/curved tile (lower level): factory buildings, warehouses, residential buildings, steel structure roofs, balancing practicality and aesthetics.
