IV. How to Choose a Suitable Valve Bag Making Machine

Choosing the right valve bag making machine requires consideration of several factors beyond just price:

1. Define production needs

First, you need to clearly define your production requirements, including: material characteristics (powder, granules, lumps), packaging weight (e.g., 5-50 kg/bag), and production speed requirements. Different material characteristics require different feeding methods and packaging technologies.

2. Examine the quality and performance of the equipment.

When selecting a valve bag making machine, the key considerations should be the equipment's metering accuracy (e.g., accuracy ≤ ±0.2%), stability , and durability . High-quality equipment typically uses imported load cells and weighing instruments to form a weighing control system, which can maximize the machine's weighing control accuracy and stability.

3. Consider after-sales service and technical support.

After-sales service is an important factor that cannot be ignored when purchasing a valve bag making machine. Understand whether the supplier provides installation, commissioning, operation training, maintenance, and other services, as well as their after-sales response time and warranty policy (such as a one-year warranty from the date of purchase with the warranty certificate).

4. Assess energy consumption and operating costs

In addition to the equipment purchase cost, the energy consumption and operating costs of the equipment also need to be considered . These include power supply (e.g., 4-11kW), gas consumption (e.g., gas consumption of 0.2-0.6m³/min), and daily maintenance costs.

5. Focus on environmental protection and safety performance.

With increasingly stringent environmental protection requirements, environmental and safety performance should be a primary consideration when selecting valve bag making machines . Priority should be given to equipment equipped with a dust removal system (air volume 800-2500 m³/h) and designs that meet explosion-proof requirements (especially important for industries such as chemical manufacturing).

V. Maintenance and Care of Valve Bag Making Machine

Proper maintenance and upkeep can extend the service life of valve bag making machines and ensure long-term stable operation of the equipment.
