What are the advantages of using automatic sandblasting machine for surface treatment of hardware parts?

Compared with manual sand blasting and chemical treatment, the surface treatment of hardware parts has obvious advantages in treatment efficiency, quality consistency, process adaptability, safety and environmental protection, and the specific benefits are as follows:

Improve processing efficiency and reduce labor costs.

The automatic sandblasting machine can realize the whole automation of loading, sandblasting and blanking, and can continuously process hardware parts in batches with the feeding mechanism such as conveyor belt, turntable or manipulator, and the processing efficiency is 3-5 times that of manual sandblasting. There is no need for a special person to hold a spray gun, which greatly reduces the labor input, and is especially suitable for mass and standardized production of hardware (such as stamping parts, fasteners, automobile parts), effectively reducing the processing cost of unit parts.

Ensure the consistency of surface quality and improve product precision.

The automatic sandblasting machine can accurately set core parameters such as sandblasting pressure, spray gun angle, sandblasting distance, conveying speed, etc., and the parameters are stable without fluctuation in the whole process, which can ensure that the surface roughness (Ra value) and cleanliness of hardware parts in the same batch and at different positions are completely consistent, and avoid the problems of "missed spraying" and "overspray" caused by uneven strength and angle deviation of manual sandblasting.

For parts with precision requirements, they can be fixed by customized fixture to avoid displacement and deformation of parts during sandblasting, accurately control the degree of deburring and derusting, and do not damage the original dimensional tolerance of parts.

Adapt to complex hardware, no dead angle treatment.

For special-shaped hardware parts with blind holes, grooves and threads, the automatic sandblasting machine can be equipped with multi-spray guns and multi-angle layout, or with rotating tooling, so that the abrasive can evenly cover all surfaces and hidden parts of the parts, and completely remove burrs, scales and stains in the holes. Compared with chemical pickling, there will be no problems such as "residual liquid medicine in the hole" and "corner corrosion", and the treatment will be more thorough.

Enhance the adhesion of subsequent processes and improve the durability of products.

After sandblasting, the surface of hardware parts will form a uniform micro-rough surface, which can greatly improve the coating adhesion of subsequent spraying, electroplating, oxidation and other processes, and avoid coating peeling and peeling. At the same time, sandblasting can remove the stress layer on the surface of parts, improve the performance of metal surface, enhance the fatigue strength and corrosion resistance of parts, and prolong the service life of products.

Environmental protection, in line with safety standards.

The automatic sandblasting machine is equipped with a closed-loop dust removal and recovery system, the abrasive can be recycled, the dust can be collected efficiently, and it will not spread to the workshop environment, thus avoiding the dust pollution caused by manual sandblasting, and meeting the Comprehensive Emission Standard of Air Pollutants. Compared with chemical pickling, there is no need to use acid-base solution, no waste water discharge, reducing the cost of environmental protection treatment, and avoiding excessive corrosion of parts and damage to operators by chemical reagents.

Reduce abrasive loss and save production cost.

The abrasive separator of automatic sandblasting machine can separate unbroken abrasive from dust and debris, and qualified abrasive can enter the sandblasting cycle again, and the utilization rate of abrasive can reach over 90%, which is much higher than 60%-70% of manual sandblasting, greatly reducing the procurement cost of abrasive. At the same time, the automatic operation of equipment reduces the scrap rate of parts caused by human operation errors, further saving production costs.

Safe operation, reducing the risk of personal injury.

The automatic sandblasting machine is a closed operation, and the operator does not need to directly contact the abrasive sprayed at high speed, but only needs to monitor the running state of the equipment, thus avoiding the risk of eye and skin damage caused by abrasive splashing during manual sandblasting. The equipment is equipped with emergency stop, overload protection and other safety devices to further improve the operation safety.
