Plastic knives, forks, and spoons are a common type of tableware made from plastic materials through injection molding technology. This article will provide a professional introduction to plastic knives, forks, and spoons from two aspects: their benefits and injection molding process.
Firstly, plastic knives, forks, and spoons have various benefits. Firstly, plastic knives, forks, and spoons are lighter in weight compared to traditional metal tableware, making them more convenient and comfortable to use. Secondly, plastic knives, forks, and spoons have good wear resistance and corrosion resistance, are not prone to rust and discoloration, and have a longer service life. In addition, plastic knives, forks, and spoons also have good insulation performance and are not easy to conduct heat, which can effectively avoid the risk of burns. In addition, plastic knives, forks, and spoons can be made into various shapes and colors through injection molding technology to meet the personalized needs of different consumers.
Secondly, the manufacturing process of plastic knives, forks, and spoons mainly adopts injection molding technology. Injection molding process is a processing method that injects molten plastic into a mold through an injection machine, cools and solidifies it to obtain the desired product. Specifically, the injection molding process includes steps such as raw material processing, injection molding, cooling and solidification, and demolding. Firstly, it is necessary to process the plastic raw materials, including drying, mixing, and dyeing. Then, place the processed plastic particles into the hopper of the injection machine, and heat and melt them to turn them into a molten state. Next, inject the molten plastic into the mold and solidify it during the cooling process. The cooling system plays a role in reducing the temperature of the mold to ensure the quality and dimensional stability of the product. After the plastic knife, fork, and spoon are cured, the mold opens and closes, and the finished product is taken out.
In summary, plastic knives, forks, and spoons, as a common type of tableware, have the advantages of being lightweight, wear-resistant, corrosion-resistant, and insulated. Its manufacturing process adopts injection molding technology, by injecting melted plastic into the mold, cooling and curing to obtain the required product. The injection molding process has the characteristics of high efficiency and flexibility, which can meet the production needs of plastic knives, forks, and spoons of different shapes and colors. With the continuous progress of technology, injection molding technology will further develop and improve, providing more possibilities for the production of plastic tableware.
Disposable plastic pvc, pp ice cream spoon, plastic knife and fork, strong toughness, not easy to break.
According to customer information, it can be customized and engraved with logo.
Horizontal injection molding machine operation
Startup check
Before turning on the power supply, first check the power line, confirm whether the hydraulic oil is sufficient, check whether the proximity switch of the safety door is out of order, and whether the safety door switch is smooth.
The mold must be installed manually
Close the safety door by matching the mold with the circle setting of the fixed plate, and turn the mold switch to mold installation adjustment to close the mold.
Adjust the mold so that the center of the nozzle is up and down with respect to the nozzle, align it left and right, and mount the saddle at the back, and fix the mold on the fixed plate.
Adjust the stroke and speed of the ejector pin. If the stroke of the ejector pin exceeds the stroke, it may damage the mold. Therefore, at the beginning, it must be set shorter.
Adjust the mold closing safety device.
Adjust the mold closing safety device.
Manual operation of forming operation
Switch the operation selector switch to the "Manual" position, and then press the pump start button.
The safety door on the left side of the reverse operation must also be closed.
When the mold switch is switched to "mold closing", the mold closing action starts and the high pressure is
completed.
The ejection device switches to "forward" and the nozzle contact is completed.
When the switch of the ejection device is switched to "ejection", the ejection action will be carried out, and the pressure will be converted from the ejection (primary) pressure to the secondary pressure. Note: Start the screw drive motor 15 minutes after the temperature of the heating cylinder reaches the set temperature to avoid damaging the screw.
Measure the pressure holding time
Switch the screw switch to the "rotation" position for metering.
Switch the injection device switch and move the injection device back to the appropriate position.
After measuring the cooling time, switch the mold switch to "mold opening".
Press the ejection switch to measure the ejection of the finished product.
