A decoiler machine is a widely used equipment for feeding and uncoiling materials in automated stamping production. It is cost-effective, easy to operate, has a low failure rate, and a high degree of automation, making it a preferred choice for material handling in automated press operations. The types of decoiler machines are classified based on the maximum width of the coil they can handle, ranging from MT-200 to MT-1500, each with standard parameters for coil inner diameter, outer diameter, and load capacity.

When customers purchase a decoiler machine, they often directly ask for the price of a specific model, such as “How much does an MT-500 decoiler machine cost?” However, when our sales personnel inquire about essential parameters such as material thickness, weight, inner diameter, outer diameter, subsequent equipment compatibility, factory space, press type, and speed requirements, customers often have no information. This approach to purchasing is not scientific.

Although a decoiler machine is a relatively simple piece of equipment, to ensure it suits automated stamping production, attention must be paid to the following points during the selection process:

Understand the basic parameters of your stamping materials, including material type, width, thickness, weight per coil, inner diameter, and outer diameter. The decoiler machine is a vertical feeding device where the coil is fixed by mounting it on the expanding and contracting drum of the decoiler machine. Therefore, the inner diameter, outer diameter, and load capacity are limited. Often, standard decoiler machine models may not fit customer requirements precisely. In such cases, customization based on actual inner diameter, outer diameter, and load capacity is necessary. Additionally, knowing the material type and thickness is crucial. When dealing with hard materials or thick materials, a pressure arm may need to be installed to prevent the coil from loosening during uncoiling.

Assess the factory space and the compatibility with subsequent equipment. Decoiler machines come in powered and non-powered versions. Non-powered heavy material decoilers rely on subsequent machines to pull the material for uncoiling, requiring a short material waiting area but causing wear on the motors of subsequent machines. Powered decoiler machines have their own power source and control material feeding through a 24V sensor rod, requiring a larger waiting area. Therefore, when selecting a decoiler machine, it is necessary to consider the layout and space of the factory and the compatibility with subsequent equipment to determine whether a powered or non-powered decoiler machine is suitable. If the factory space is small, and the material needs leveling but lacks a leveling device, a decoiler and leveling machine combined is recommended.

Consider whether additional accessories are needed, such as a frequency converter, hydraulic expansion, pressure arm, photoelectric sensor, and material loading trolley. Adding a frequency converter to the decoiler machine ensures smoother feeding and better synchronization with subsequent machines, preventing frequent starts and stops that could damage sensor components. Hydraulic expansion simplifies loading when dealing with heavy materials. A pneumatic pressure arm prevents materials from loosening during uncoiling of thick materials. A photoelectric sensor replaces the contact sensor rod for non-conductive materials and materials with surface coatings, controlling the decoiler machine’s start and stop. A material loading trolley automates the coil loading process.

When selecting a decoiler machine, it is also important to consider the uncoiling speed required by the stamping process. If paired with a high-speed press, a horizontal decoiler machine designed for high-speed uncoiling should be used to meet the demands of the stamping process, rather than opting for a cheaper decoiler machine that might not be suitable.
