The product cost provided by the equipment manufacturer in the equipment manual is generally only for reference. Because the cost calculation provided by some equipment manufacturers often ignores the actual utilization rate of the equipment, it does not strictly calculate the loss rate of slurry and additives, and does not strictly assess the impact of factors such as product qualification rate on the cost, but it is fully calculated, so and The actual cost does not exactly match.
For example, the utilization rate of the slurry (including additives) is not 100% in the production process. If the loss of slurry and additives (loss in the wet end process) is considered, a meal of 25 grams can be produced without a ton of dry slurry. Boxes of 40,000 are calculated based on the 95% slurry utilization rate, but 38,000. If you consider the 95% pass rate, 38,000 will become 36,100. With this item alone, the cost of the product differs by nearly 10%. If the utilization rate of the equipment can no longer meet the requirements, then the product cost and economic benefits will be farther away.
Precautions for the use of egg tray machine equipment molds: remember to lubricate the molds before use to minimize the friction of each mold operation and extend the service life. Before the machine is stopped, it is forbidden to directly touch the mold with your hands to prevent people from being injured. Use special clamps to pick and place products and reduce work. When not in production, the mold of the egg tray equipment should be cleaned of the debris in the mold cavity, and then coated with anti-rust oil. Regularly check and measure the size of the mold, record the data, and do mold loss analysis to control the quality of the product within the qualified range.
Except for the cutters, die-cutting dies are made of ordinary carbon steel; setting dies and shaping dies are usually made of brass, aluminum alloy and stainless steel. The forming mold is currently made of brass, aluminum alloy and resin. When it is used in industrial packaging products with low precision, it can be directly manufactured by casting. Those with high precision must be manufactured by mechanical cutting. The transfer mold in the forming mold is preferably manufactured by directly overturning the resin from the corresponding punch or concave mold with high precision. If there is a paper sample, a low melting point alloy can be used to directly overturn the mold using the sample as a master mold.
The composition of the cost of paper-molded packaging products also has in common with general products, such as materials, energy consumption, wages, rent, water charges, electricity costs, transportation costs, depreciation costs, start-up fees, office fees, operating expenses, working capital loans Interest, etc., we can estimate the cost price per unit weight of the product based on the relevant elements listed above and the approved output, but this is just a statistic and does not truly reflect the cost of a product. Therefore, the quotation for a certain product cannot be based solely on the product weight. In the cost components, wages, rent, depreciation costs, start-up costs and food expenses of some enterprises are basically a fixed value, so the greater the output, the lower the cost. Therefore, the quotation for a certain product should consider the quantity of the order batch.
