There are too many parts in the injection molding department. If you count slowly, there are hundreds. Since it is called an accessory, its characteristic is that it is not linked to the BOM, that is, it cannot be directly linked to the order quantity. There are many categories-production materials, maintenance materials, tools, labor insurance supplies and office stationery, but they are not without traces, such as:

1. Labor protection and office stationery, which are the most basic, such as masks, anti-static gloves, helmets, double-sided tape, copy paper, gloves, finger covers, 2. The means of production are somewhat related to the number of people/orders, such as blank stickers, alcohol, cotton pads, art knives, sandpaper, polishing paste, diamond paste and decontamination.

3. Maintenance materials are linked to the number of molds/equipment, such as rags, degreasing oil, thimble oil, cleaning agent, antirust oil, release agent, butter, O-ring, argon gas, gasoline blowtorch, alcohol lamp, water pipe, sleeve, red lead, zebra glue, copper rod and rubber pad. There are many statistical determination methods for each item, which is rather cumbersome.
