The plastic tray is a kind of plastic processing technology, which is mainly made by heating the spreading plastic hard sheet to become soft, and then vacuum-absorbing it on the surface of the mold and forming it after cooling. The raw materials for the plastic tray box are PVC, PS, PP, PET, PETG and flocking, anti-static, conductive, etc.
The plastic tray is mainly divided into three categories:
1. Ordinary plastic tray. It is widely used in industrial packaging, medical device packaging, toy packaging, cosmetic packaging, electronic product packaging, etc.
2. Flocking plastic tray. It is a common material that is coated with adhesive flocking to give the blister surface a flocked feel. It can be used to improve the grade of packaging products, as well as for cosmetics, wine boxes, etc.
3. Anti-static plastic tray, which is a plastic tray with special materials. The surface resistance of the material is determined according to the different requirements of customer products. The resistance value is generally in the 3rd power of 10 to the 10th power of 10 ohms. Mainly used for plastic pallets of electronic and IT products.
Plastic tray product type show: Plastic Tray Sampling Process:
Design concept: Design a package that protects the product, beautifies the product, is easy to use, has a reasonable layout, does not waste space and other factors (as many products as the mold strength and space allow), while ensuring the customer's product quality.
The design of the mold needs to comprehensively consider the size of the customer's product, the complexity of the product, and the customer's requirements. In addition, pay special attention to which parts need protection.
Material Selection: The selection of sheets has a direct effect on the molding success or failure and the quality. In the actual production demand, due to the variety of plastic tray requirements, the nature of the forming sheet is diversified, and the performance requirements of the forming sheet are focused on different situations of the plastic tray. General packaging needs better transparency, shock, explosion, heat resistance, cold resistance, and so on. Food packaging requires more tasteless, odorless, non-toxic, and corrosion-resistant and some require high-temperature water and steam resistance. Generally, according to the aesthetic decoration, there is a variety of colors on the plastic tray sheet.
For the selection of mold materials, plaster molds are generally used for sample proofing. It has the characteristics of short production time, easy modification, low cost, and convenient sample production. It is not suitable for mass production due to comprehensive factors such as low strength, easy deformation, excessive die seam, and surface pitting. Generally, copper molds are used for products with large notch and low precision, which are easy to grind and polish, and have the characteristics of heat resistance, high transparency after molding, and slow cooling (25-30 seconds). The cost of the copper mold is low, but because its surface is electroplated copper, the copper mold will be damaged by too many production times. Therefore, in order to meet the requirements of the smoothness of the surface, and the product is small in size, small in spacing, and regular in shape, only by using aluminum molds can it have the longest life.
Whether it is aluminum or copper mold, once the mold is completed, the production process without worrying about the size will have too much change, stability in general!
The main process of plastic tray mold making: design, processing, punching, and polishing. It is noteworthy that some products need to be inverted buckle because some buckle is round, some buckle is square, and some buckle is irregular, so specific according to customer requirements design. Size labeling is also a key point. Mainly the external and internal dimensions of the entire product to be marked clearly. The next is the internal size of the slot requirements, special sizes are described separately.
After the whole mold is processed, air holes should be punched in the corners of all the grooves of the mold to facilitate the suction of the product in place, and it will not affect the quality of the suction molding. Blister stamping surface polishing after completion. Learn More>
