A meter blasting machine is available in different designs and variants to cater to various requirements. Some of the common types are as follows.
Hook meter shot blast machines
A hook shot blasting machine uses a hook arrangement to hang and blast clean various metal components. It is an enclosed blasting device usually powered by an electric motor for effective cleaning, stripping, and surface preparation of metals. The machine's hook design provides an efficient, flexible, and fast blasting process that caters to components with complex shapes. In addition, the design allows for easy loading and unloading of the items being blasted.
Wire mesh belt meter shot blast machines
In a wire mesh belt shot blasting machine, the part to be blasted is placed on a moving belt. The belt then loads the part into the blasting area, where it is blasted by moving impellers. The blasted part is then offloaded by the same belt. This meter blasting machine is mostly used for small blasted pieces that need consistent surface preparation. One of the main advantages of a mesh belt machine is its ability to continuously feed parts into the blasting area, increasing productivity.
Undercarriage/ rubber belt meter shot blast machines
The undercarriage/rubber belt shot blasting machine works similarly to the wire mesh machine, where an item is conveyed into the blasting area, blasted, and off-loaded. However, this machine uses either a steel or rubber belt to convey items. This machine is more suited for larger workpieces that need thorough blasting.
Rotary table meter shot blast machines
A rotary table in a shot blasting machine can be described as an indexed turntable that rotates after each index to expose the blasted part to another area. This meter blasting machine is ideal for flat, round, and small-sized objects. The workpiece in the machine can also be fixed and turned for all-around surface preparation.
Wire bristle tire blast meter machines
This machine is explicitly designed to prepare and clean tire metallic wheels by using a wire bristle. In this type of meter machine, a hub supports the wheels, and an impeller throws the blasting media at a high velocity to clean off irregularities on the wheel's surface.
The meter shot blasting machine is an equipment that needs regular inspection and maintenance to ensure that it works well and to see if there is any part that needs to be changed or repaired. This ensures that the machine has a long life span and also keeps the blasting area safe for any users. The steps of maintenance can be done quite easily and do not take a long time to complete.
It is a good idea to always clean the blasting equipment and get rid of residual media and debris. Move parts should be lightly lubricated so that they do not wear out over time. If the machine has a dust collection component, make sure that the filters are cleaned as well so that no dust accumulates. The belts, chains, and bearings should be inspected from time to time to ensure they are working properly and there is no misplaced or missing parts that can affect the functionality of the blasting machine.
Any parts that are required to be oiled or greased should be done, and in case any parts are damaged, they should be repaired or replaced immediately. The electrical components and connections should also be checked on a regular basis, and the air hoses, cables, or pipes should be inspected for any leaks or damages that may reduce the efficiency of the shot blasting machine.
Following the manufacturer's instructions is a good way to know what parts need maintenance and what safety precautions should be kept in mind to ensure that the shot blasting machine is used safely and effectively.
Aerospace industry components:
The aerospace industry demands components with strict weight thresholds, durability, and aerodynamic performance. Therefore, an accurate surface polishing of the coupling components is required. The use of a meter shot blasting machine in the polishing and de-scaling of these highly specialized and critical components is necessary for both employee safety and the longevity and smooth use of the parts.
Medical device manufacturer parts:
In this manufacturing environment, a meter machine is used to improve the surface area of critical components such as valves and fasteners. Thereby, increasing the functionality and life expectancy of the medical equipment. This creates a more seamlessly functional device for the end user, which is of the utmost importance in the medical industry.
Automotive industry parts:
Frequency machines are ideal for use in high-volume automotive industries. A meter machine can be used to de-scale and improve the surface of commonly used parts, such as fasteners and joints. Higher productivity and efficiency are of the utmost importance when looking to product improve in this industry.
Construction industry aluminum and steel parts:
Aluminum and steel parts are frequently used during the construction of high-rise buildings and infrastructure projects. Hence, the construction industry demands a reduction in metallic inclusions and improved surfaces for better coatings. Therefore, the use of a meter machine can be employed on these steel and aluminum parts to prepare their surfaces for coatings, thus improving the life expectancy of the parts.
Consumer electronics metal components:
In the ever-growing consumer electronic device market, metal parts are most commonly used to connect devices and form their structural makeup. Improving the surface of these metal parts helps to ensure better electrical connectivity and enhanced user experience. A meter machine can be used to achieve this goal by removing impurities from the surface of the metal so that it may be used in various electronic components, such as smartphone frames, connectors, and laptop chassis.
When choosing a shot blasting machine, one should consider the flow of steel shots, the area to be blasted, and the object's geometry. The object's geometry includes the size and nature of the object (whether it has a flat surface or is tubelike, etc.). Another important thing to consider is the shot material and its flow direction. A meter shot blasting machine typically uses steel shots or iron shots. An air-blast machine usually uses aluminum oxide, which flows in an upward direction.
Things like machine capacity, blasting pressure, and type of operator should also be considered. The machine capacity is determined by the number of feet it can cover and square feet per minute. Blasting pressure ranges from 0.5 kg/cm2 to 7 kg/cm2, and the operator can be manual or automatic. Machines with automatic operators tend to cost more and be more efficient. In an automatic machine, a belt feeds the objects, and in a semi-automatic machine, a trolley is used to feed the objects.
It is also essential to consider what type of meter blasting machine is needed. An indoor machine will not have a recovery system, while an outdoor machine will. Indoor machines typically use a bag filter for air cleaning and may or may not have a blast cabinet. In areas where no recovery system is available, a wet blasting machine suffices, which avoids the dangerous issue of dust pollution.
Last but not least, the seller's reputation and after-sales service support are crucial in ensuring the customer selects a satisfactory product.
Q1: How does the meter shot blasting machine work?
A1: The blasting machine works by using an impeller to throw the shot blast at high velocity onto the surface to be cleaned or prepared. The impacted surface then goes through a rebound channel where it is collected and removed from the meter blasting machine.
Q2: What types of surfaces can the meter shot blasting machine be used on?
A2: The machine can be used on a wide range of surfaces including steel, cast iron, concrete, aluminum, ceramic and metal alloys. However, the meter shot blasting machine is not suitable for use on softer materials like plastic or rubber.
Q3: What is the blasting media for a meter shot blasting machine?
A3: The blasting media can be steel shots, steel grit, chilled iron shots, angular aluminum oxide, slag crystals or sanding quartz among others. The choice of media depends on the surface of the object to be blasted and the level of blast finish required.
Q4: What are the limitations of a meter shot blasting machine?
A4: Some common limitations include the ability to reach difficult geometries or corners, consume large quantities of blasting media and high power requirements.
