The difference between vacuum molding and injection molding -- carding duct
1. Different production methods
Vacuum molded products are formed by heating the sheet material, then pushing it out and bonding it with the mold through suction, and then cooling it to shape.
Injection molding is the process of squeezing the melted plastic onto an injection mold under pressure, and then cooling it to form the product.
2. Different types of uses
Vacuum forming is commonly used in electronic products, digital products, toys, stationery, hardware accessories, etc. The types of vacuum forming products include vacuum forming boxes, vacuum forming foam shells, vacuum forming trays, vacuum forming covers, and so on.
Injection molding is commonly used for phone cases, computer cases, plastic cups, mouse cases, hardware accessory cases, etc.
3. Different production cycles
Vacuum molded products are a hot and soft production mode that allows multiple molds to vacuum multiple products at once. The production cycle of injection molds is relatively long, which is produced by pressing multiple products from a single mold shape, without the need for further punching to directly form products.
4. From a practical application perspective
Vacuum molding belongs to the packaging form of products, while injection molding belongs to the product form of items. The same thing is that both belong to the plastic category of products.
Extended Information:
Injection molding refers to the process of making shoes by machines, where the upper is tied onto an aluminum last and PVC, TPR, and other materials are directly injected into the sole by a turntable machine, forming the sole in one go.
Nowadays, there is also PU (chemical name polyurethane) injection molding (machines and molds are different from general injection molding).
Advantages: Due to being machine made and having a large output, the price is low.
Disadvantages: If there are multiple styles, changing molds can be more troublesome, making it difficult to shape the shoes, and the workmanship of the shoes is not as exquisite as cold adhesive ones. Therefore, it is generally suitable for orders with a single sole style.
The main advantages of vacuum packaging are saving raw materials, light weight, convenient transportation, good sealing performance, and meeting the requirements of environmentally friendly and green packaging; Can package any irregular products without the need for additional cushioning materials for packaging; The packaged products are transparent and visible, have a beautiful appearance, are easy to sell, and are suitable for mechanized and automated packaging, facilitating modern management, saving manpower, and improving efficiency.
