When purchasing shuttering magnet with reliable quality for PC components in the situation of uneven product quality and lack of industry standards in the market, the following aspects can be considered:
1.Brand
• In the prefabrication construction industry where there is fierce competition with inconsistent product standards and issues like low price and low quality, choosing suppliers with brand influence is a top choice when there's no product trial comparison.
• Among many brand suppliers, it's necessary to comprehensively consider the plant equipment, production capacity, qualification certificate, quality control and R & D team of each brand supplier according to the enterprise's own development plan.
2.Quality
1)Magnet Block
• Magnetic block is the core of the shuttering magnet, and the magnet within it is crucial. The quality of the magnet impacts the suction of the shuttering magnet , and the coating (anti-corrosion) and metal protective layer (anti-scratch) of the magnet affect its service life. Both aspects are essential. To detect the actual working suction of the shuttering magnet, professional testing equipment is needed, like the suction testing equipment before the shuttering magnet leaves the factory and the testing equipment for testing the suction (as shown in relevant figures).
2)Shell
• Currently, the shell materials of shuttering magnet available on the market are mostly steel Q235 and stainless steel 201 , 304 , 316 . Generally speaking, the thickness of the shuttering magnet plate ranges from 3 to 4 millimeters.
• When it comes to strength, steel Q235 will be better than stainless steel. However, in terms of anti-rust performance, stainless steel performs better than high-strength carbon steel. When making a purchase, you can select the appropriate material and thickness based on the actual usage scenarios.
• Moreover, attention should also be given to the frame structure of the shell. The structure that incorporates a reinforcing plate and bolt design is stronger and more durable compared to the one with direct welding.
3)Accessory
Saixin has visited numerous component factories and witnessed a large number of shuttering magnet . However, various quality issues have emerged because the quality of the selected accessories fails to meet the required standards.
The auxiliary accessories for shuttering magnet include switch indenters, springs, bolts, stainless steel rings, and so on. When making purchases, special attention must be paid to the quality of these accessories. For instance, one should focus on the dimensional accuracy of switch indenters, the performance grade of bolts, and whether the springs conform to the national standards.
The production of shuttering magnet must have standardized quality inspection procedures that cover everything from raw material procurement to processing and assembly. For example as shuttering magnet , the quality inspection procedures typically involve the following steps:
IQC (Incoming Quality Control) --- Inspection of semi-finished products --- Inspection of finished products ---- Incoming test --- OQC (Outgoing Quality Control)
Even a shuttering magnet has to pass all these tests from the stage of raw materials to becoming a finished product before it can be judged as a qualified product. If we compare the shuttering magnet to a car, the magnetic block is like the engine, which is the core component of the entire product. The switch pressure head is analogous to the steering wheel as it controls the working direction of the whole product, while the shell and screws are equivalent to the frame parts. Just as with a car, for a complete shuttering magnet, the quality of all accessories cannot be overlooked. If there is a problem with any one accessory, it will impact the working performance of the entire product. Therefore, when making purchases, we should opt for products from brands that have passed qualified quality inspections instead of blindly chasing low prices and choosing inferior products.
3、Model and Quantity
Once the supplier of shuttering magnet has been selected, the next step is to determine how to choose the appropriate shuttering magnet. This demands a comprehensive consideration of various aspects in the production process of precast concrete products, such as the usage scenarios of magnetic fixed products (whether for fixed formwork or vibrating formwork), the spacing of reinforcements, the temperature inside the steam curing kiln, the height of the mold, and the specifications and models of embedded parts, etc.
Take the shuttering magnet as an example. When laminated plates are produced on the fixed die table, it is recommended to use shuttering magnet with a suction force ranging from 600 to 800 kg. The service spacing of the shuttering magnet (generally between 1 and 2 meters) can be adjusted according to the height and thickness of the die.
In the production process of the assembly line vibration die, shuttering magnet with a suction force of 1000 kg can better meet the production requirements. When manufacturing wallboards, 1350 kg magnetic boxes can be chosen. And when producing prefabricated beams, columns or other special-shaped components, shuttering magnet with a suction force ranging from 1800 to 2100 kg can be selected and used in combination with corresponding fixtures.
With these basic data at hand, we are able to analyze the total quantity and budget for the shuttering magnet needed by a specific project.
