Aluminum foil lunch boxes are an environmentally friendly, safe and recyclable food packaging. They are now widely used in airline food and catering for large events. In the future, they will be more widely used. The production process of aluminum foil lunch boxes is roughly divided into six steps: spreading → oiling → feeding → stamping → blanking → testing. During the production process, the aluminum foil is subjected to a stamping pressure of up to 40 to 80 tons, the stamping frequency is 1 to 2 seconds, and the average consumption is 20,000 pieces per day.
Stamping oil plays a very important role in the production process of aluminum foil lunch boxes, including: heat dissipation, cooling, protecting the aluminum foil surface, protecting stamping equipment and molds, rust prevention, corrosion prevention and prevention of aluminum foil surface bonding. In response to the special lubrication requirements of the aluminum foil lunch box industry, the lubricating oil uses refined narrow-fraction base oil as the raw material and is combined with environmentally friendly lubricants and extreme pressure agents to develop special stamping oil for aluminum foil lunch boxes.
The stamping oil has suitable viscosity, excellent lubrication, load-bearing and cooling properties, can improve work efficiency and make the product have the best brightness and fineness. It has excellent volatility, no residue after evaporation, keeps the operation light and avoids the adhesion of the workpiece. The production of foil lunch boxes is due to its high pressure and high temperature process.
The special stamping oil for aluminum foil lunch boxes has excellent extreme pressure performance and excellent temperature resistance, which effectively handles the heat generated by friction on the surface of equipment and molds, greatly extending the service life of equipment and molds. The special stamping oil for aluminum foil lunch boxes is colorless and odorless, clean and environmentally friendly, does not contain any harmful substances to the human body, provides a high-quality working environment, and can meet the high safety requirements of aluminum foil lunch boxes as food containers for the use of lubricants. The use of special stamping oil for aluminum foil lunch boxes can improve the qualified rate of aluminum foil lunch box production.
