Mold Section

Mold Type: Single Charge Material: Made from 5CrNiMo steel, heat-treated with surface polishing. Both the internal and external surfaces are electroplated, with the mold head surface chrome plating thickness between 0.04-0.05 mm. Heating Method: Heating is done using a closed-type heating system with a heating sterjn. Effective Width: 1300 mm Adjustment Range: 1-4 mm Heating Zones: 7 zones Heating Power: 3.5 kW per zone  

Pattern Printing Roller

• Working Speed: 1-5 meters per minute.
• Control Motors: 1.5 kW x 2 sets.
• Roller (Valve) Dimensions: φ295mm × 1300mm.

The system uses two types of rollers:

• Upper Roller: Raised pattern roller.
• Lower Roller: Reverse roller.

Both rollers are treated with hard chrome plating on the surface (depth: 0.10-0.15mm) to ensure durability and precision in pattern transfer. Control System: The system operates with an ABB inverter. Spiral runners are used in the roller, ensuring uniform surface temperature for consistent pattern quality. The synchronization of the upper and lower cylinders is guaranteed by two separate motors, ensuring that both rollers work together seamlessly. This setup guarantees high-quality pattern printing on the material.

Shaping Equipment

 

PLC-Controlled Cutting Equipment and Assembly Table

Cutting Type: The cutting equipment utilizes a circular saw type, with a motor power of 2.2 kW. It is designed with a special adjustable locator for precise placement, ensuring the accuracy of each cutting position. The machine's center of gravity is low, contributing to more stable operation during cutting. It is equipped with a dust collection system to minimize airborne particles during the cutting process. The cutting system uses a microcomputer-based electrical control, allowing for high-precision operation and minimizing errors, ensuring reliability in production. Assembly Table:

• Material: Stainless steel
• Length: 3000 mm

This assembly table offers a sturdy, durable platform for assembling cut parts, optimized for efficient workflow and providing flexibility for various post-processing tasks.
