High-quality raw materials are the foundation for producing high-quality plastic food storage boxes. We select food-grade plastic particles as raw materials to ensure that the products are safe and non-toxic, and meet relevant national standards and the requirements of the catering industry.
Before the raw materials enter the production workshop, we will conduct strict screening and testing. Through professional testing equipment, we conduct comprehensive testing on the physical properties, chemical properties, and hygiene indicators of plastic particles to ensure the stable and reliable quality of raw materials. Only raw materials that meet the standards can enter the next production stage.
In order to prevent defects such as bubbles and shrinkage during the injection molding process, the raw materials need to be dried before use. We use advanced drying equipment and set appropriate drying temperatures and times according to different plastic materials and environmental humidity to ensure that the moisture content in the raw materials is controlled within a reasonable range.
Molds are the key tools for the production of injection molded products. The rationality of their design directly affects the product quality, production efficiency and cost. We have a professional mold design team. According to the needs of customers and product characteristics, combined with advanced design software and rich experience, they design molds with reasonable structure, high precision and long service life.
Mold manufacturing adopts advanced processing equipment and processes, such as CNC machining centers, electric discharge machining, wire cutting, etc. These equipments can ensure the precision and surface quality of the mold, and improve the production efficiency and service life of the mold. In the mold manufacturing process, we strictly control the quality of each link to ensure that the quality of the mold meets the design requirements.
After the mold is manufactured, it needs to be debugged and optimized. Through trial molding, we can find the problems existing in the mold and make adjustments and improvements in time. During the debugging process, we will adjust the parameters of the injection molding machine, such as temperature, pressure, injection speed, etc., according to the quality requirements of the product to ensure the stable and reliable quality of the product.
The process mainly includes steps such as feeding, plasticizing, injecting, holding pressure, cooling, and demolding. First, add the dried plastic particles into the hopper of the injection molding machine. Through the rotation and heating of the screw, the plastic particles are melted into a liquid state. Then, under high pressure, inject the liquid plastic into the mold cavity. After the injection is completed, perform pressure holding to ensure the dimensional accuracy and uniform density of the product. Next, perform cooling to solidify and form the product in the mold. Finally, the product is ejected from the mold through the demolding mechanism.
In the injection molding process, we strictly control the quality of products. Through online detection equipment, real-time detection of product dimensions, appearance, weight, etc. is carried out. When problems are found, the parameters of the injection molding machine or molds are adjusted in time. At the same time, we will also regularly perform maintenance on the injection molding machine and molds to ensure the normal operation of the equipment and the precision of the molds.
After demolding, the product may have some defects such as burrs and flash. Deburring and trimming treatment is required. We use professional deburring equipment and tools to process the edges of the product to ensure the appearance quality of the product.
For some products with higher requirements, we will also carry out grinding and polishing. Through grinding and polishing, the surface finish of the product can be improved to make it more beautiful.
To meet the personalized needs of customers, we can also perform printing and spraying on products. Through printing and spraying, various patterns and texts can be printed on the product surface to increase the added value of the product.
We have established a strict quality inspection system and conduct comprehensive inspections on each product to ensure that the products meet relevant national standards and customer requirements.
The contents of quality inspection mainly include appearance quality, dimensional accuracy, physical properties, hygiene indicators, Etc. We use advanced detection equipment and methods, such as three-coordinate measuring instruments, tensile testing machines, hardness testers, etc., to conduct comprehensive inspections on products.
Qualified products will be packaged to prevent damage during transportation and storage. According to the characteristics of the product and the requirements of clients, we select appropriate packaging materials and packaging methods. After packaging is completed, the product will be stored in the warehouse and wait for shipment.
Our innovation directions mainly include product design innovation, production process innovation, material innovation and other aspects. In terms of product design innovation, we combine the needs of customers and market trends to design more beautiful, practical and personalized products. In terms of production process innovation, we continuously explore new injection molding technologies and post-processing processes to improve production efficiency and product quality. In terms of material innovation, we actively research and develop new food-grade plastic materials to improve the performance and environmental protection of products.
