1. Look at the board: The boards used in the jewelry showcase mainly include large core boards and density boards. The surface of the high-quality large core board is smooth and flat, and the internal connection is seamless. The surface of the large core board with bad quality is rough, and there are gaps in the interior, and some are even hollow in sections. The density board mainly depends on whether it is environmentally friendly, and the unenvironmentally friendly density board has a serious formaldehyde content that exceeds the standard, which will cause great harm to the human body. Then look at the color of the density board, whether it smells pungent, how the eyes feel, and so on. A good MDF looks light in color and smells little, so it won’t irritate your eyes when you get closer, and vice versa.

2. Look at the paint: The paint for the jewelry showcase mainly includes furniture paint and glass baking paint. The furniture paint is preferably environmentally friendly and tasteless. If the furniture paint is inferior paint, the strong smell will cause long-lasting damage to people and affect sales. Therefore, the paint must be baked in a professional paint room, so that the paint surface will be smooth and free of impurities. Flow paint, no bubbles, no cracks, thick paint film and good texture. Then the glass of the jewelry showcase should be cleaned before the glass is painted, otherwise it will not be wiped off after the paint is painted, which will affect the quality of the jewelry showcase. In addition, it must be baked at high temperature to improve the wear resistance and hardness of the paint surface.

3. Look at the glass: As the glass is a transparent object, the quality of the glass can basically be seen through visual inspection during identification. The appearance quality is mainly to check the flatness of the glass, and observe whether there are quality defects such as bubbles, inclusions, scratches, lines, and fog spots. Glass is divided into ultra-white glass and ordinary glass. Ordinary glass has a lot of impurities and looks green or blue, making jewelry look unsightly. Ultra-white glass has excellent light transmission, is bright and has no impurities, and can well bring out the brilliance and sparkle of jewelry. In addition, the edges of the finely ground glass are smooth and fine, while the ordinary edging glass has jagged edges. The lamp trough should be bonded without shadow glue, watermark, and air bubbles.

3. Look at LED lamps: The quality of LED lamps in jewelry showcases directly affects the image of the corporate brand and the sales volume of the products. Generally good LED lights have sufficient brightness, good quality, high price, and long life. The higher the brightness, the better, and the color temperature closer to the color of sunlight is the best. Generally, the quality of large chip LED is better than that of small chip, and the price is proportional to the size of the chip. The radiator can look at the appearance of the luminaire. If the external or internal of the luminaire is made of aluminum, the larger the contact area between the radiator and the air, the better, which is good for heat dissipation and can better extend the life of the luminaire. In addition, the hardware of the jewelry showcase should be opened and closed freely, moderately tight, and durable.
