How to choose a suitable wet automatic sandblasting machine?
Choosing a suitable wet automatic sandblasting machine requires comprehensive consideration of product characteristics, production requirements, equipment performance and cost. The following are the specific points:
Product related factors
Material: Products with different materials have different requirements for sandblasting. If the hardness of the metal material is high, it may require a large sandblasting pressure and a coarse abrasive; Glass, ceramics and other materials are relatively fragile, so it is necessary to choose a sandblasting machine with low pressure and fine abrasive to avoid product damage.
Shape and size: For products with complex shapes and deep holes or cavities, it is necessary to choose a sandblasting machine with multi-angle sandblasting function and suitable spray gun to ensure effective sandblasting of all parts; For larger products, a sandblasting machine with large working cabin volume and strong carrying capacity of the conveying system should be selected to ensure the smooth entry and exit of products and sandblasting operation.
Surface treatment requirements: if the product surface is required to achieve high cleanliness and high roughness, it is necessary to choose a sandblasting machine with good sandblasting effect and efficient abrasive circulation system; For products with special surface texture or pattern requirements, it is necessary to consider whether the sandblasting machine has the corresponding sandblasting process and control accuracy.
Production demand factor
Production efficiency: according to the production scale and output requirements, choose a sandblasting machine with suitable sandblasting efficiency. Continuous automatic sandblasting machine is suitable for mass production and can realize continuous sandblasting of products; Intermittent sandblasting machine is suitable for small batch and multi-variety production, and the sandblasting process can be flexibly adjusted.
Degree of automation: If the enterprise pursues a highly automated production process and reduces manual intervention, it can choose a sandblasting machine with the functions of automatic loading and unloading, automatic adjustment of sandblasting parameters, automatic fault alarm and so on. A highly automated sandblasting machine can not only improve production efficiency, but also ensure the stability of sandblasting quality.
Equipment performance factor
Sandblasting pressure and flow: Sandblasting pressure and flow determine the strength and speed of sandblasting. Generally speaking, sandblasting machines with a pressure of 0.4-0.8MPa and a flow rate of 1-3 m/min are suitable for most conventional sandblasting operations. For some special materials or difficult sandblasting tasks, a sandblasting machine with higher pressure and flow rate may be needed.
Abrasive types and particle sizes: Common abrasives include quartz sand, emery, glass beads, etc. Different abrasives have different hardness, wear resistance and sandblasting effect. Appropriate abrasives should be selected according to product materials and surface treatment requirements. Abrasive particle size will also affect the sandblasting effect. The larger the particle size, the higher the surface roughness after sandblasting.
Number and arrangement of spray guns: The more spray guns, the larger the sand blasting coverage area and the higher the sand blasting efficiency. The arrangement of spray guns is also very important. Reasonable spray gun arrangement can ensure the uniformity of sand blasting and avoid the occurrence of sand blasting dead angle. For large or complex products, multiple spray guns may be needed for multi-angle sandblasting.
Recovery and filtration system: An efficient recovery and filtration system can reduce abrasive waste, reduce production costs and ensure a clean sandblasting environment. The recovery system should have good abrasive recovery ability, which can recover and reuse the abrasive scattered in the sand blasting process in time; The filtration system should be able to effectively remove impurities and dust in the abrasive and ensure the purity and quality of the abrasive.
Other factors
Price and budget: under the premise of meeting the production demand and quality requirements, choose the sandblasting machine with appropriate price according to the budget of the enterprise. Don't blindly pursue equipment with high configuration and high price, and you can't choose products with poor quality and performance in order to save costs.
After-sales service: sandblasting machine is a consumable product, and various faults and problems may occur during use. Therefore, it is necessary to choose suppliers with good after-sales service to ensure that the equipment can be repaired and maintained in time in case of failure, reduce downtime and ensure the normal production.
