FAQ
1. Can one machine produce different corner bead sizes?
Yes. However, different corner bead profiles normally require different forming tooling. Before production, our engineering team reviews your drawings and recommends the most suitable machine configuration. This ensures stable forming quality and reduces unnecessary adjustments during operation.
2. What raw materials can be used for corner bead production?
The machine is primarily designed for galvanized steel coils, which are widely used for plaster corner beads in construction projects. Material thickness and coil specifications can be configured according to your production requirements and local market standards.
3. How much factory space is required for installation?
A standard production line requires approximately 25 meters in length. The final layout may vary depending on coil handling, finished product storage and available workshop space. DAPU provides production line layout drawings before delivery to help customers plan installation efficiently.
4. Is technical support available after machine installation?
Yes. DAPU provides installation guidance, commissioning support and operator training. Our technical team assists customers throughout the startup process to ensure the machine reaches stable production as quickly as possible.
5. How do I choose the right corner bead machine for my market?
The best solution depends on your finished product specifications, production targets and local customer requirements. By sharing your drawings or sample products, our engineers can recommend a suitable machine configuration that matches your business goals and investment plan.
6. What factors affect the quality of finished corner beads?
