Create quality with science and technology, enrich life with intelligence
Casters are widely used in almost any industry. There are about 15,000 different casters in the world, used in furniture, industry, agriculture, logistics, warehousing, docks, national defense science and technology and other industries and fields. As a professional caster design expert, manufacturer and excellent export enterprise, Changche Caster has continuously invented various casters according to the needs of different industries.
However, the current Chinese caster market has many varieties and specifications, which dazzles users. There are thousands of caster factories, and the quality of casters varies. In order to allow users to choose high-quality caster products and to facilitate users to quickly choose suitable high-quality casters, the appearance of the casters is analyzed to provide users with methods to identify high-quality casters and low-quality casters.
1. Analyze the appearance of the caster packaging and choose high-quality casters
Generally speaking, regular caster factories use cartons or pallets to package and transport casters, marked with obvious marks (including the product name of the caster, the manufacturer's address, telephone number, etc.), which effectively prevents the casters from being damaged during transportation. Small factories usually use woven bags for packaging because they do not have mass production or to save costs, which cannot ensure that the caster products are not damaged during transportation.
2. Analyze the appearance of the caster bracket and choose high-quality casters
1. Analyze the material selection of the caster bracket to prevent substitution.
Caster brackets generally use injection molded brackets or metal brackets. Injection molded brackets have relatively small output and are mainly used in the furniture and furniture caster industry and the medical caster industry, so we will not go into details here. We will focus on the appearance analysis of the metal bracket. The thickness of the metal bracket of the caster ranges from 1mm or even smaller to 30mm or even thicker steel plates, which is mainly determined according to the load requirements of the caster.
Regular caster manufacturers usually use genuine steel plates, while small factories usually use head and tail plates to reduce costs. Head and tail plates are actually inferior steel plates. The thickness of head and tail plates is uneven, and the price of head and tail plates is also much different from that of genuine plates. The performance of caster products, such as appearance, load and other qualities, are also far apart.
2. Analyze the size of the caster bracket to prevent cutting corners
Many small caster factories deliberately reduce the steel plate requirements of their products in order to save costs. For example, the casters with high frequency and large usage in the domestic caster market are mainly 4-inch (diameter 100mm), 5-inch (diameter 125mm), 6-inch (diameter 150mm), and 8-inch (diameter 200mm) casters. This type of caster was originally produced based on the usage habits of the United States, also known as American casters. The steel plate thickness usually used is 6mm (but due to China's steel plate standards, it is generally a negative tolerance). Therefore, the steel plate thickness of regular caster manufacturers should be 5.75mm, and some small caster factories, in order to reduce costs, usually use 5mm or even 3.5mm, 4mm steel plates, which will inevitably cause the performance and safety factor of the casters to be greatly reduced in use.
3. Analyze the surface treatment of the bracket to prevent shoddy products.
Regular caster factories produce high-quality casters with beautiful surfaces and no burrs. At the same time, in order to ensure the anti-corrosion treatment of metal brackets, caster brackets generally use electroplating zinc (including electroplating white zinc, blue and white zinc, colorful zinc, anti-gold), electrophoresis, spraying, plastic spraying, dipping, etc. The market is dominated by galvanized brackets. In order to improve the adhesion of electroplating zinc, regular caster factories generally use shot blasting. More precise casters will use vibration grinding treatment, which can effectively remove burrs caused by stamping, welding, etc. At the same time, it can better provide the adhesion of the anti-corrosion layer on the surface of the caster. For example, the 600 series casters of Wanda Wheel Industry are all shot blasted on the surface, and there will be small and symmetrical craters on the surface (because many direct users are not very familiar with it, so it is specially stated here that such surface treatment can better improve the adhesion of the coating). Some small caster factories generally do not invest in such a high-cost production process.
3. Analyze the appearance of casters and choose high-quality casters
Casters are used for movement, whether they are injection-molded plastic wheels or processed metal caster wheels, so the wheels of casters must be round or spherical. This is the most basic principle and must not lose the roundness. The wheels of casters have a smooth surface, no bruises, uniform color, and no obvious color difference.
4. Analyze the working performance of casters and choose high-quality casters
For high-quality universal wheels, when the top plate rotates, each steel ball should be able to contact the steel plate runway surface, rotate smoothly, and have no obvious resistance. When the caster wheel rotates, it should rotate flexibly without obvious up and down jumping.
