The production cycle of paper corner guards can vary based on a variety of factors, including required quantity, customization requirements, production equipment and factory production capabilities, etc. Typically, the typical production cycle can be anywhere from a few hours to a few days, depending on several factors:

1. Order quantity: The production cycle usually increases as the quantity of the order increases. If ordering larger quantities, the production lead time may be longer.

2. Customized requirements: If special customized designs, sizes or colors are required, the production cycle may be relatively long as this requires additional processing time.

3. Production equipment and processes: Different production equipment and processes will have an impact on production speed. Some factories may have highly automated equipment that can produce paper corner guards faster, while others may require more manual operations, resulting in longer production cycles.

4. Seasons and factory busyness: Factories may be busier during certain seasons or holidays, which may extend the production cycle. Therefore, you may need to consider the factory's work schedule when placing an order.

5. Shipping time: Production lead time usually does not include shipping time. If you need to ship your paper corner guards to a different location, shipping time will also require additional consideration.

The best way is to contact the supplier or manufacturer that produces paper corner guards, ask about their production cycle, and develop an order plan based on your specific needs. They can usually provide you with an accurate production schedule.
